[mingw64] [libplacebo-git] meson.build:47:12: ERROR: C++ static library 'OGLCompiler' not found

[statusquont]

Hello, building for 64-bit, it fails on libplacebo-git

I've attached the relevant logs and pasted the error message below. Hopefully I followed the instructions correctly. I appreciate your time with any helpful responses!

I tried to comment out that library in ffmpeg_options.txt file

#--enable-libplacebo

and then re-ran the media-autobuild_suite.bat script. It got much further along this time, but then failed on ffmpeg-git

@statusquont Just change in media-autobuild_suite\local64\lib\pkgconfig\libjxl_cms.pc Requires: to Requires: lcms2

[hydra3333]

That line already had Requires: libhwy libbrotlienc libbrotlidec libjxl_cms note the libjxl_cms

so I added lcms2 on the end of the line and am re-running ...

edit: Um, no, that change didn't fix anything.

[Ajaja]

@hydra3333 Requires: ... libjxl_cms can not be in libjxl_cms.pc Obviously you changed a different file.

[maclauk]

I had the same original problem of "'OGLCompiler' not found"

The combination of #--enable-libplacebo and Requires: lcms2 allowed me to successfully build FFMPEG.

[hydra3333]

edit: @Ajaja you are indeed correct, apologies. inattention is a confounding blighter.

I think a better way would be add FORCE_SYSTEM_LCMS2 to -DJPEGXL_{FORCE_SYSTEM_BROTLI,STATIC}=ON

Like this -DJPEGXL_{FORCE_SYSTEM_BROTLI,FORCE_SYSTEM_LCMS2,STATIC}=ON

(The final effect of this is equal to modify the .pc file like you do)

Or use skcms, by deleting SKCMS from the "=OFF" list above. What the difference between lcms2 and skcms? Why jxl official cmake enable skcms by default and m-ab-s disable skcms by default? Curious.

Here's a issue on the libplacebo git that has a patch to compile. https://github.com/haasn/libplacebo/issues/226

[jfe1205]

Is there a way to apply this patch during the build process as there does not seem to be any urgency to apply it to the git?

[cantrell216]

I got this error till i turned on mpv=1. Then rebuild if you want with mpv=2. Seemed to grap a little extra from shaderc or libplacebo with it on. idk.

[jfe1205]

Can't pretend to understand why, but that worked for me too! Thanks for the tip.

Edit: Having looked at the different meson.build that is used with MPV enabled, I do now understand, but why it should need a different meson.build is beyond me!

[jfe1205]

This can now be marked as fixed, I believe as all builds fine now, thanks.
