missing gcc configure "--enable-plugin" package for windows

[labba]

hi i'm using windows Mingw and couldn't find a copmlete build of Mingw with latest gcc that was gcc configure with "--enable-plugin" can you please build and upload a new build with gcc configured with "----enable-plugin" ? it should generate a new folder that is now missing in the latest build the new folder should be generate in "mingw32\lib\gcc\i686-w64-mingw32\8.3.1" as a "plugin" folder with some libs and includes so it would be possible to compile plugins also in windows build.. it was published here that this is now supported : https://www.phoronix.com/scan.php?page=news_item&px=GCC-Plugins-Windows-MinGW

plugin support is not possible by default with gcc on windows.

There was some work some years back when clang was in a much worse shape on windows, to get the plugin for clang building on windows so that we could use it.

Sadly while it did work to some extent, it was a pita to build (required the use of dlfcn-win32 for dlopen support), also instead of seperate plugins for clang functions, we had to yank them all into the same dll which had to be placed correctly in the gcc tree by hand.

So main reason its not a thing you will be likely to see in gcc on windows is that it relies on loading from shared objects (this is by no means an easy feat on windows).

So if you realy want it the best way to get it would be to patch gcc yourself, and if its working correctly you could ask alexey if he would consider adding it to the package.

I built gcc-8.3.1 with "--enable-plugin" on windows and its working correctly. you can download mingw8.3.1 from https://sourceforge.net/projects/libportable/files/Tools/mingw8.3.1-clang-win64_32.7z now and try it out for yourself.

If you want gcc-plugin enabled, patch the PKGBUILD, make sure it works and submit a pull request. Then the maintainer will consider it.

BTW, two weeks ago someone did that for mingw-w64-gcc-git.

Neat :)

how did you compile it ? i have tried many times and couldn't compile it ..

what is the setup you have and dependencies / commands you done to compile this ?

Thanks!

i can't find the binary for download anymore.. can it be re-uploaded ?

Hi, Just in case this thread is still relevant, I built gcc-13.2.0-5 with plugin support on MinGW just yesterday and it's working perfectly. It's been tested with the ODB C++ ORM Compiler which I also built (ODB 2.5.0-b.25). I will submit the patch next week. It's quite very simple, just check the ../configure section in the PKGBUILD file of the mingw64-gcc package after cloning the repository and add --enable-plugin option, then build following the instructions on the MSYS2 Documentation. You can then check if your GCC support plugging with $ gcc --print-file-name=plugin, it will output a directory path where the cc1.exe.a plugging file is located if it support plugging, if not, the output will be "plugin"

The patch to the gcc build was submitted years ago, in 2017 , patch link by Boris Kolpackov and is already in the mainstream gcc code

i remember atleast some later versions of gcc where it did not work (export ordinal to large) but if it works in the latest build thats something :).

I tried building with plugin support enabled, It succeeds on 64-bit envs and fails on mingw32.

Please can you post the error message with the build configuration you used
