mingw with windows gcc plugin suppot is missing

[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 :

Looks like something interesting 👍. Building now.

BTW you may try building yourself by invoking the command makepkg-mingw in the mingw-w64-gcc-git directory in a MSYS2 shell.

[lhmouse]

Done. New builds are now available at https://gcc-mcf.lhmouse.com/.

thanks!

i have tried building from git and gotten the following error after a while:

Hmm perhaps something (including system headers, libraries etc.) changed during your build. Or there was some misconfiguration of your environment that caused a wrong compiler to be invoked for that stage.

[labba]

i think its misconfiguration on my env. but i haven't seen any clear environment setup requirements.

[lhmouse]

Running makepkg-mingw inside an MSYS2 shell (not a mingw32 or mingw64 shell) should suffice. In reality that isn't what I do. I have my PATH set like /mingw64/bin:/mingw32/bin:/usr/bin:<...> and invoke makepkg-mingw in CMD, and that should just work.

[labba]

it's not enough since while i have compiled i found that i was missing "diffutils" package that is also missging that wasn't reported as required also "tar" wasn't required and i had to install it.

so the pre-requirement are still not complete and need to give a try and build on top of a clean system to find what is the needed pre-requisites to have a good build like is being done on a docker like image that you can see in the script how it build the entire environment and compile it.

[lhmouse]

Try pacman -S base-devel.

[labba]

is there someone that build GCC for window (32 bit version) but without all the MCF model ? something lighter ? couldn't find any beside your version that works amazing but requires all the DLLs imports of the MCF build when i'm using a plugin on windows ..

[lhmouse]

You may build one yourself.

pacman -S base-devel mingw-w64-{i686,x86_64}-toolchain
git clone https://github.com/msys2/MINGW-packages.git
cd MINGW-packages/mingw-w64-gcc-git
makepkg-mingw

[labba]

sorry for not returning to this .. i have stopped since it never successfully compiled so now that i have a lot of time i can document every step that i have done on a clean system and i hope you will be able to help me.

here are the full steps until compilation failure i got:

OS: installation on Win10 x64.

1, install msys - msys2-x86_64-20200602
https://www.msys2.org

2. Trying to install packadge failed
   $ makepkg-mingw
   => WARNING: You don't have installed mingw-w64 toolchain for architecture x86_64.
   => WARNING: To install it run: 'pacman -S mingw-w64-x86_64-toolchain'
   => WARNING: You don't have installed mingw-w64 toolchain for architecture i686.
   => WARNING: To install it run: 'pacman -S mingw-w64-i686-toolchain'

3. installing all dev pack
   $ pacman -S base-devel

4. Clean install doesn't have git… so install git
   pacman -S git

git clone https://github.com/msys2/MINGW-packages.git

cd MINGW-packages/mingw-w64-gcc-git
makepkg-mingw

=> WARNING: You don't have installed mingw-w64 toolchain for architecture x86_64.
=> WARNING: To install it run: 'pacman -S mingw-w64-x86_64-toolchain'
=> WARNING: You don't have installed mingw-w64 toolchain for architecture i686.
=> WARNING: To install it run: 'pacman -S mingw-w64-i686-toolchain'

7. since we are still missing toolchain installing more required toolchain:

pacman -S mingw-w64-x86_64-toolchain
pacman -S mingw-w64-i686-toolchain

8. applying command:
   $ makepkg-mingw

After long compilation Getting the following error:

Try removing languages (changing these to no) that you don't need from PKGBUIlD:

_enable_fortran=yes
_enable_ada=yes
_enable_objc=yes

See msys2#6463 (comment) for details.

i have done it and after started again a clean compilation getting the following:
