交叉编译wxGtk [英] Cross-compile wxGtk
问题描述
我必须交叉编译wxGtk(旧版本:2.8.11)并设法设置环境，以使 configure 成功运行.
I have to cross-compile wxGtk (an old version: 2.8.11) and managed to setup the environment so that configure runs successfully.

我已经打印出报告该问题的编译器命令:
I've printed the compiler command which reports the issue:

如果我从此编译器命令中删除了两个 -Wl，-rpath-link = 语句并手动调用它，则该命令将成功.
If I remove the two the -Wl,-rpath-link= statements from this compiler command and invoke it manually, the command succeeds.
似乎附加的 -Wl 语句使编译器使用 main()-函数(似乎是通过提供的)错过了源文件.include/wx/wxprec.h )，但我真的不知道怎么回事.
It seems the additional -Wl statements make the compiler miss the source file with the main()-function (which seems to be provided via ./include/wx/wxprec.h), but I don't really see how that could happen.
对于能解决该问题的任何建议，我将不胜感激.
I'd be grateful about any advice how I can address this problem.
更新
configure -脚本具有通常的选项(无-source )
The configure-Script has the usual options (no --source)
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
--target=TARGET configure for building compilers for TARGET [HOST]
其中-target 无关紧要.我必须检查的其他选项.正如我在评论中提到的那样，到目前为止，我只看到它们与前缀一起使用，例如 aarch64-linux-gnu ，用于来自 $ PATH 中的程序包存储库中的工具链，以及相应的库等.
where --target is of no interest. The other options I'll have to check. As I mentioned in the comments, I've so far only seen them being used with prefixes e.g. aarch64-linux-gnu for toolchains from package repositories which are in the $PATH, and with according libraries etc.
因此，我已将工具链二进制文件的文件夹添加到path并配置为
So I've added the folder for toolchain binaries to path and configured with
./configure --enable-unicode --disable-shared --prefix=/usr/local/<target> --host=i686-pc-linux-gnu
configure: WARNING: If you wanted to set the --build type, don't use --host.
If a cross compiler is detected then cross compile mode will be used.
checking build system type... x86_64-unknown-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
这看起来是正确的.我想在本地计算机上构建另一个目标.
That looks correct. I want to build on my local machine for another target.
但是:
checking for GTK+ - version >= 2.0.0... no
*** Could not run GTK+ test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GTK+ is incorrectly installed.
configure: error:
The development files for GTK+ were not found. For GTK+ 2, please
ensure that pkg-config is in the path and that gtk+-2.0.pc is
installed. For GTK+ 1.2 please check that gtk-config is in the path,
and that the version is 1.2.3 or above. Also check that the
libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config
--libs' are in the LD_LIBRARY_PATH or equivalent.
不幸的是，这是有道理的.工具链本身只有一些库，但没有GTK库.
Unfortunately that makes sense. The toolchain itself only has some libraries, but does not have the GTK-libraries.
/opt/my_toolchain/toolchain_base/
GTK库和其他库位于单独的文件夹中:
The GTK libraries and other libraries are in a separate folder:
/opt/my_toolchain/additional_libs/
工具链的二进制文件不知道此文件夹.
And the toolchain's binaries don't know about this folder.
我认为整个问题的出现是因为wxGtk为 host = i686-pc-linux-gnu 构建库，而且还构建了可执行文件(例如 wx-配置)，用于 build-system = x86_64-unknown-linux-gnu .
I think the whole issue arises because wxGtk builds libraries for the host = i686-pc-linux-gnu, but also builds executables (e.g. wx-config) for the build-system = x86_64-unknown-linux-gnu.
推荐答案
wxGtk 2.8.11跨版本终于可以使用以下设置了:
The wxGtk 2.8.11 cross-build is finally working with the following setup:
export PATH=/opt/my_toolchain/toolchain_base/bin/:${PATH}
export PKG_CONFIG_SYSROOT_DIR=/opt/my_toolchain/additional_libs
export PKG_CONFIG_PATH=/opt/my_toolchain/additional_libs/usr/lib/pkgconfig
export PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1
# make sure those env vars are not left from previous setup
unset CC
unset CXX
unset CPPFLAGS
unset CFLAGS
unset CXXFLAGS
unset LD_LIBRARY_PATH
unset LDFLAGS
unset PKG_CONFIG_DIR
unset PKG_CONFIG_LIBDIR
./configure --enable-unicode --disable-shared --prefix=/usr/local/<target> --host=i686-pc-linux-gnu --build=x86_64-linux-gnu
make
sudo make install
