Библиотека инструментов wxWidgets. Сборка

Выдержка из Wiki: wxWidgets — это кросс-платформенная библиотека инструментов с открытым исходным кодом для разработки кроссплатформенных на уровне исходного кода приложений, в частности для построения графического интерфейса пользователя (GUI).

Библиотека имеет набор классов для работы с графическими изображениями, HTML, XML документами, архивами, файловыми системами, процессами, подсистемами печати, мультимедиа, сетями, классы для организации многопоточности, отладки, отправки дампов и множество других инструментов.

Совет: При установке каких либо программ, библиотек, распаковки пакетов и т.д., лучше всего использовать, в мастере установки программ, настройки (опции) по умолчанию. Поверьте, это вызовет намного меньше забот, и меньше плясок с бубном вокруг библиотек и программ. Это касается, библиотек, программ, и всевозможных компиляторов.

Настройка компилятора заключается в том, что необходимо добавить в системную переменную окружения Path, путь к бинарным сборкам компилятора, если этого не сделал мастер установки по умолчанию. Обычно это: C:\TDM-GCC-32\bin (если директорией установки (распаковки) был выбран корневой каталог диска C:\ );

Процесс сборки будет похож на этот скриншот:

FAQ, Note: The codeblocks-13.12mingw-setup.exe file includes the GCC compiler and GDB debugger from TDM-GCC (version 4.7.1, 32 bit). The codeblocks-13.12mingw-setup-TDM-GCC-481.exe file includes the TDM-GCC compiler, version 4.8.1, 32 bit. While v4.7.1 is rock-solid (we use it to compile C::B), v4.8.1 is provided for convenience, there are some known bugs with this version related to the compilation of Code::Blocks itself.

IF UNSURE, USE «codeblocks-13.12mingw-setup.exe»!

Примечание: Общее время компиляции занимает в среднем порядка 30-40 минут. Да-да, библиотека не такая уж и маленькая, имеет кучу классов.

Далее стандартная процедура, запускаем мастер установки, и устанавливаем программу с опциями по умолчанию.

должен быть такой код:

если необходимо редактируем.

Глобальные переменные проекта должны быть настроены следующим образом ( Settings—>Global variables ):

__GNUWIN32__
__WXMSW__
wxUSE_UNICODE
WX_PRECOMP

Окно Project build options ( wx_test ) [Вкладка Linker settings ]:

Окно Project build options ( Debug ) [Вкладка Linker settings ]:

Окно Project build options ( Release ) [Вкладка Linker settings ]:

Бывают и неприятности. Например линовка может выдавать следующую ошибку:

rem gcc_mswudll\monodll_xh_combo.o: file not recognized: Memory exhausted
rem collect2.exe: error: ld returned 1 exit status
rem mingw32-make.exe: *** [..\..\lib\gcc_dll\wxmsw28u_gcc.dll] Error 1

Проявляется на некоторых 32 битных платформах при компоновке монолитной динамической библиотеки из-за нехватки памяти. Из-за того, что линковщик собранный для x86 архитектуры, не может использовать адреса выше 2Гб, даже на x86_64 архитектуре. Поэтому смена компилятора обычно не помогает, перепробованы MinGW4.4.1TDM, всё семейство MinGW4.6.x, а также MinGW4.7.0, хотя в сети есть информация, что собирается под TDM-GCC 4.5.2 sjlj.

Также обойти проблему можно не используя монолитную сборку, или отказавшись от создания динамических библиотек для монолитной сборки, статические собираются без этой ошибки.

Решаются явным указанием стандарта при сборке библиотеки (добавление опции):
CXXFLAGS=»-std=gnu++11″

Upd1: вероятно в последних релизах MinGW баги пофиксили, теперь можно смело собирать при помощи указанного компилятора, соблюдая те же (описанные) правила.

p/s.
Пост ориентирован прежде всего на начинающую аудиторию программистов, и не в коем случае не претендует на истину в последней инстанции.
В следующих постах опишу как «правильно» собрать библиотеку компьютерного зрения OpenCV.

Patches for the underlying binutils, GCC, GDB, and winpthreads components used to be included as part of a combined TDM source and build scripts release tarball, but are now kept in individual Github.com source repositories per component:

In order to duplicate the build process used for TDM’s binaries, you will need the following packages:

The 10.3.0 TDM32 and TDM64 GCC binaries were built as native bootstraps in Windows 10 (64-bit), using previously built toolchains with the same set of patches, under the MSYS2 environment. The build scripts in this package will probably not work in Cygwin, WSL, or GNU/Linux without modification.

Generally, building GCC consists of first building its support libraries (gmp, mpfr, mpc, isl, libiconv, winpthreads, and windows-default-manifest), combining these with binutils and the runtime API into the «staging prefix», and then building GCC itself. GCC is built to expect it will be installed to the staging prefix but for the installation step is actually staged into a different directory.

About

TDM-GCC is a cleverly disguised GCC compiler for Windows!

Источник

Tdm gcc что это

This edition of TDM-GCC is a dual-arch multilib bootstrap of GCC’s x86_64-w64-mingw32 target, built to run on 32-bit or 64-bit Windows and generate binaries for 32-bit or 64-bit Windows.

If you encounter any bugs with this edition of TDM-GCC, it is likely that they will be inherent to the x86_64-w64-mingw32 GCC target or to the MinGW-w64 runtime API. As such, you are encouraged to report bugs to the tracker for the MinGW-w64 project on SourceForge (https://sourceforge.net/p/mingw-w64/bugs/).

Please note that the MSYS2 project also maintains easy-to-install GCC 64-bit and 32-bit toolchains at https://www.msys2.org/, and you are encouraged to try them out as well to see if your problem exists on both toolchains.

However, you may also submit a helpful bug report at https://github.com/jmeubank/tdm-gcc/issues, though TDM-GCC is only supported on a minimal best-effort basis.

Using the TDM/MinGW installer is highly recommended; it can automatically install TDM-GCC as well as all supplementary base system packages. The installer uses a standard wizard interface with reasonable defaults.

Do not install TDM-GCC packages on top of a previous GCC installation of any kind.

You will need to download and unpack a set of archives. A minimal base set of archives is required; there are also some additional components that are optional, adding support for additional programming languages or GCC features.

TDM-GCC provides a ZIP-compressed version and a TAR.XZ-compressed version of each archive. Use whichever is easiest.

You’ll need GDB particularly if you want to use an IDE with debugging support.

Unpack all the archives to an empty directory. You may choose any path, though it is recommended that you avoid a path with any spaces in the folder names. Finally, consider adding the bin subdirectory to your Windows PATH environment variable.

TDM-GCC is currently a one-man show, so support is best-effort. You can submit helpful problem reports at https://github.com/jmeubank/tdm-gcc/issues, and they will be triaged. Reports that appear to consistently cause TDM-GCC to be unusable for a majority of users will be addressed first.

Support for the x86_64-w64-mingw32 GCC target, as well as for any incompatibilities in its runtime API, is provided where possible by the MinGW-w64 project. The MinGW-w64 project provides multiple venues for support including a mailing list, an IRC channel, a web-based discussion forum on SourceForge, and a web-based issue tracker on SourceForge.

For more information about MinGW-w64, see the project’s home page at http://mingw-w64.sourceforge.net/.

If you provide your own manifest, it will override the default manifest.

The default manifest looks like this:

GDB AND GDB32: TDM BUILDS OF THE GNU DEBUGGER

The TDM «gdb» and «gdb32» packages are slightly-modified builds of GDB for (respectively) 64-bit and 32-bit Windows that include Python 3, enable libstdc++ Python pretty printing by default, and use wrapper executables to allow 64-bit and 32-bit cooperation in the «bin» directory. For more details, see the separate README files (README-gdb32-tdm.md, README-gdb-tdm64.md).

32-BIT OR 64-BIT COMPILATION

In a 64-bit binary, all pointer math is 64-bit by default, and the built-in size_t and ptrdiff_t types are 64 bits in size (some other types are larger also).

Additionally, the following preprocessor definitions will be in effect:

Be sure to use «-m32» or «-m64» at both the compile stage and the link stage.

There are also two different exception handling mechanisms used in the generated code, depending on whether you compile for 32-bit or 64-bit:

32-bit programs compiled with this edition (TDM64) will use SJLJ (setjmp / longjmp) exception unwinding, which is somewhat compatible with Microsoft system DLLs and other MSVC-generated code. Cleanup code will not be executed when unwinding through MSVC function frames, you cannot throw C++ or other language-specific exceptions and have them caught in MSVC code, and you cannot catch C++ or other language-specific exceptions thrown by MSVC code. However, the exception unwinder can traverse MSVC function frames in the stack in order to reach GCC function frames.

64-bit programs compiled with this edition (TDM64) will use 64-bit Windows SEH (Structured Exception Handling) exception unwinding, which has better MSVC compatibility. Cleanup code will be executed when unwinding through MSVC function frames, but you still can’t catch language-specific exceptions from MSVC code or throw language-specific exceptions to MSVC code.

POSIX THREADS, C++11 STD::THREAD AND OTHER SYNCHRONIZATION FEATURES

TDM-GCC includes a pthreads compatibility layer called «winpthreads». «Winpthreads» is one of the libraries distributed by the MinGW-w64 project, and it allows GCC to be compiled with full pthreads compatibility, which is necessary to enable std::thread and other threading related functions in the C++ runtime.

Because of TDM-GCC’s continuing goal of minimizing extra DLLs, winpthreads has been compiled statically. It will be statically linked with every program you compile, which will increase your baseline executable size.

The same mechanism used in libgcc and libstdc++ to allow EXEs and DLLs to share state for handling exceptions has also been patched into winpthreads to allow your EXEs and DLLs to share C++11 thread handles via the underlying pthread handles.

Because every program you compile will now rely on winpthreads, you should make sure to read and comply with its MIT-style license, included in the file «COPYING.winpthreads.txt».

LTO (LINK-TIME OPTIMIZATION)

EXCEPTIONS AND DLLS

The TDM releases of x86_64-w64-mingw32 GCC support propagating exceptions out of shared libraries (DLLs) whether you use DLL versions or statically-linked versions of the GCC runtime libraries. The statically-linked runtimes utilize shared memory regions that will allow all TDM-GCC-compiled executables and DLLs (for the same architecture) to propagate exceptions correctly. This method incurs a small execution overhead as compared to the shared library method, but has the very important benefit of not requiring you to redistribute extra DLLs with your program.

GCC RUNTIME LICENSE

There has been an update to the license exception clause that permits you to distribute programs that make use of the GCC runtime libraries without requiring you to license your programs under the GPLv3. As always, please be familiar with the terms of GCC’s GPLv3 license and exception clauses, and do not redistribute any portion of GCC, including its runtime DLLs, in any way except as granted by the license. If you are unclear about which permissions are granted by the license, please consult a lawyer and/or the Free Software Foundation (http://www.fsf.org/).

OPENMP AND WINPTHREADS

TDM-GCC has been built to allow the use of GCC’s «-fopenmp» option for generating parallel code as specified by the OpenMP API. (See http://gcc.gnu.org/onlinedocs/libgomp/ for details.) If you want to use OpenMP in your programs, be sure to install the «openmp» optional package.

The OpenMP support in the TDM-GCC builds has received very little testing; if you find build or packaging problems, please send a bug report (see BUGS above).

LibGOMP, GCC’s implementation of OpenMP, currently only supports the use of the POSIX Threads (pthreads) api for implementing its threading model. This edition of TDM-GCC relies on the «winpthreads» library (part of the MinGW-w64 project libraries and included in this distribution). The «winpthreads» library is distributed under the terms of an MIT-style license; see «COPYING.winpthreads.txt» for details.

In order to correctly compile code that utilizes OpenMP/libGOMP, you need to add the «-fopenmp» option at compile time AND link time. By default, this will link the static version of winpthreads to your program, and you should not need to distribute any additional DLLs with your program. If you plan to distribute a program that relies on OpenMP and winpthreads, be sure to understand and comply with the terms of winpthreads’ license (see COPYING.winpthreads.txt).

«libpthread.a» is included in the «lib» subdirectory of the openmp package along with three other pthreads library files:

WARNINGS AND ERRORS

Recent GCC releases make significant strides in optimization capabilities, error detection, and standards compliance. For you, the end user, this often means that code which compiled and ran without problems on previous GCC releases will exhibit some warnings and maybe even a few errors.

These meaningful warnings and errors are a very good thing, as they help the programmer to write safer and more correct code. Unfortunately, there’s also a chance you might encounter incorrect warnings or errors, ICE’s (internal compiler errors, where the compiler makes a mistake and has to bail out), or even miscompilations (where your code is incorrectly compiled and produces the wrong result).

If you encounter an ICE while using a TDM-GCC build, feel free to file a bug report (see BUGS above). With any other unexpected problem, you are urged to work from the assumption that it stems from user error, and ensure that your code is correct and standards-compliant.

«« DETECTION AND COMPATIBILITY (TDM64) »»

Ideally, the binaries and compiled code produced by TDM-GCC would be ABI-compatible with other Windows compilers, such as MinGW.org, MinGW-w64/MSYS2, and even Microsoft Visual C/C++. This is sadly not the case.

«« BUGS AND KNOWN ISSUES »»

As these builds are provided on the same basis as the source releases, and the mingw32 target in GCC tends to receive somewhat less-than-average attention, some bugs are expected. If you encounter a bug that you are certain is in the GCC sources (such as an ICE), or that is due to an issue in the building or packaging process, you are encouraged to report it. Please visit the TDM-GCC Bugs page at http://tdm-gcc.tdragon.net/bugs for bug reporting instructions.

«« LOCAL FIXES AND CHANGES »»

TDM-GCC 9.2.0 release

I’m proud to present a new series of TDM-GCC binaries based around GCC 9. It’s been a long time coming, but getting back into the groove of delivering a Windows-friendly GCC toolchain was both a lot of work and an enjoyable challenge!

Check the download page for links to individual components and sources.

Change Log

Move everything to Github!

In the years since the last TDM-GCC release, Github has outpaced SourceForge for ease of development, modern dev tools, and general credibility. I’m happy to announce that all TDM-GCC sources are now on Github, and it’s much easier to track the ongoing changes and underlying process that drive TDM-GCC releases.

The TDM-GCC website is enjoying a redesign and a new home on Github pages!

Start using StGit to track patches

Switch GDB to Python 3

Enable NLS for TDM32 (not yet TDM64)
