make win32/win64 failing: Linking carla-bridge-win*.exe

Hi! I'm getting this error after make win64 CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++:

Likewise with make win32. Help?

Need some info about your system. which os and version? what version of mingw?

[muni-corn]

Gentoo Linux (kernel 5.2), mingw 6.0.0-r2. I'm building Carla from source without a package manager

Sorry for taking long to reply. Can you provide the entire build log? Or did you find a way to build it in the mean time?

It's a bit late, but I got the same error on Gentoo (amd64) and got it working somehow. I think it's important to go through the whole building process in the correct order. Not sure about the RANLIB and AR variables, but I added them. Tested with this VST-Plugin: Bitsonic Keyzone Classic. Works great :-)

These are the steps I took (for full 32 and 64 bit plugin support):

1. install the mingw toolchains for 32 and 64 bit (https://wiki.gentoo.org/wiki/Mingw): sudo emerge crossdev sudo crossdev --target x86_64-w64-mingw32 sudo crossdev --target i686-w64-mingw32

2. Rebuild mingw64-runtime with necessary tools and libraries: sudo USE="libraries idl tools" crossdev --ex-only --ex-pkg cross-x86_64-w64-mingw32/mingw64-runtime -t x86_64-w64-mingw32

sudo USE="libraries idl tools" crossdev --ex-only --ex-pkg cross-i686-w64-mingw32/mingw64-runtime -t i686-w64-mingw32

3. Install wine of course: sudo emerge wine-vanilla

4. Get the sources of Carla: cd ~; mkdir sources; cd sources git clone https://github.com/falkTX/Carla.git

5. Build Carla and install to /usr/local: cd Carla make -j9 make -j9 posix32

make -j9 win32 CC=i686-w64-mingw32-gcc CXX=i686-w64-mingw32-g++ RANLIB=i686-w64-mingw32-ranlib AR=i686-w64-mingw32-ar

make -j9 win64 CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ RANLIB=x86_64-w64-mingw32-ranlib AR=x86_64-w64-mingw32-ar

make -j9 wine32 make -j9 wine64 sudo make install PREFIX=/usr/local

OK, for anyone interested, here are working ebuilds (based on the ebuilds from the audio-overlay). New USE flags (off by default):

32bit (for native 32 bit plugins) win32-vst win64-vst

It checks for the mingw toolchain but won't be too verbose on how to install it. So be sure, that you have everything installed (see https://wiki.gentoo.org/wiki/Mingw).

To install the ebuilds, create a local overlay (described here: Gentoo Wiki: Custom repository).

Download carla-ebuilds.zip (includes v2.0.0 and 9999).

Then: mkdir -p /var/db/repos/localrepo/media-sound/carla unzip carla-ebuilds.zip -d /var/db/repos/localrepo/media-sound/carla pushd /var/db/repos/localrepo/media-sound/carla repoman manifest popd

Unmask in package.accept_keywords and change USE flags, then: emerge carla -av

hi @q-g-j I am trying to compile the carla bridges using your tutorial under Gentoo. Could you create a new ebuilds for 2.4.1 I am having this weird failure:

../mingw-std-threads/mingw.mutex.h:472:24: error: ‘class mingw_stdthread::once_flag’ conflicts with a previous declaration
  472 | using mingw_stdthread::once_flag;

It is like that file is included multiple times and failing.

but I am seeing this: https://github.com/falkTX/Carla/blob/afd6f1bc1ffdc77e90b216b8635649da5bf2453b/source/modules/mingw-std-threads/mingw.mutex.h#L21

and I don't have more c++ knowledge to understand the failures.

Hi,

this error comes from using cross-x86_64-w64-mingw32/gcc version 11 together with the mingw-std-threads headers included in the Carla source code.

I have fixed the ebuild in my portage overlay. It should pull in cross-x86_64-w64-mingw32/gcc:10 as a dependency and use this version for building.

You can get it here: https://github.com/q-g-j/qgj-overlay

Also take a look at my portage config in my other repo: /etc/portage/package.use/cross-x86_64-w64-mingw32 You can install this file before emerging cross-x86_64-w64-mingw32/gcc:10 for the correct use flags.

[mercuriete]

@q-g-j Thank you very much I will use your overlay.

One question, if this project is not compiling with mingw gcc 11 that means is an application bug isn't it? I will try to compile it using mingw gcc 10 but I would rather preffer to use gcc 11 if is possible.

[q-g-j]

You can have multiple mingw gcc versions installed and keep 11 the default. My ebuild should use version 10 even if it is not set to default.

Furthermore, having mingw's gcc installed does not interfere with the other Gentoo packages which will always use the native compiler.

[q-g-j]

I didn't manage to fix the error myself but will look into it the next days. Maybe someone has a patch for std threads or sth.
