Hi, all
I built gcc with --enable-plugin on windows.
download link:
https://pcxprj.googlecode.com/files/MinGW_GCC4.6.1_enable_plugin_experimental.7z
There is an example in the package, and this is in the example directory.
Makefile.gcc is linked with cc1
Makefile.g++ is linked with cc1plus
So the gcc has some problems, when you use gcc to call plugin, you
should link plugin with libcc1.a, and if you use g++ to call plugin,
you should link plugin with libcc1plus.a. You can't mix linking, or
you will get segment fault.
Here is the patches and build process. (I only use C/C++/Fortran, so only
modify them)
Before building it, you should have dlopen/dlsym, here we can use
dlfcn-win32 temporarily.
1. Make binutils export exe's symbols.
Patch binutils using export-symbols.diff
And using the newer binutils to build gcc.
2. Modify gcc source code to support plugin
Patch gcc using gcc-plugin.patch
3. Build gcc using --enable-plugin
4. After installing, you should copy libcc1.a, libcc1plus.a and
libf951.a to your install directory's lib.
Then you can use gcc plugin.
Note: when you use gcc to call plugin, you should link plugin with
libcc1.a, and if you use g++ to call plugin, you should link plugin
with libcc1plus.a. You can't mix linking, or you will get segment
fault.
In the end, I use the built editon to run the gcc testsuite plugin section
successfully.
So, at some time, we can port llvm-dragonegg to windows?
Any ideas?
Thanks.
