So there are problems with IMPORTED_IMPLIB, I don't know why

compilation fails:

indeed in CMakeFiles/avif.dir/build.make line 118 and later:

libavif.dll: aom-NOTFOUND

I have no idea why it fails and what to do to fix this issue

[y-guyon]

Thank you for reporting this issue.

It sounds like the following is missing IMPORTED_IMPLIB definition:

https://github.com/AOMediaCodec/libavif/blob/db72bb1313a637f9c3aeaf56e3bac43f22254d2d/cmake/Modules/Findlibyuv.cmake#L66

Would the following work for each of the problematic dependencies?

set_target_properties(yuv::yuv
                      PROPERTIES
                        IMPORTED_LOCATION "${LIBYUV_LIBRARY}"
+                       IMPORTED_IMPLIB "/home/vtorri/ewpi_64/bin/libyuv.lib"
                        IMPORTED_SONAME yuv)

[vtorri]

I have to do the same for aom, and the directory is lib, not bin. It would also be nice to remove the full path, but I don't know how to do that.

[vtorri]

actually, doing like Finddav1d.cmake seems to work:

IMPORTED_IMPLIB "${AOM_LIBRARY}")
IMPORTED_IMPLIB "${LIBYUV_LIBRARY}"

[y-guyon]

I have to do the same for aom, and the directory is lib, not bin.

Thanks for trying the solution.

It would also be nice to remove the full path

Yes, I just wanted to check if that was the right fix. We will adapt it into a proper patch soon.

[wantehchang]

@vtorri Could you run the make command in verbose mode

make -j VERBOSE=1 install > ../../make.log 2>&1

and post the command line that builds libavif.dll here?

I'd like to see what pathnames of libaom and libyuv are used as inputs when building libavif.dll. Thank you!

[vtorri]

the result above is with the patch of course

[wantehchang]

@vtorri Yes, I'd like the build output with the patch. You did not pass VERBOSE=1 to the make command. Could you try this again with VERBOSE=1? Here is the exact make command line:

make -j VERBOSE=1 install > ../../make.log 2>&1

[vtorri]

@vtorri Thanks a lot!

The command that builds libavif.dll is:

C:/Documents/msys2/mingw64/bin/x86_64-w64-mingw32-g++.exe -IC:/Documents/msys2/home/vincent.torri/ewpi_64/include -D__USE_MINGW_ANSI_STDIO=0 -D_WIN32_WINNT=0x0A00 -O2 -pipe -march=native -LC:/Documents/msys2/home/vincent.torri/ewpi_64/lib -shared -o libavif.dll -Wl,--out-implib,libavif.dll.a -Wl,--major-image-version,16,--minor-image-version,1 -Wl,--whole-archive CMakeFiles/avif.dir/objects.a -Wl,--no-whole-archive @CMakeFiles/avif.dir/linkLibs.rsp

It does not have libaom and libyuv as inputs. I guess they are hidden in the CMakeFiles/avif.dir/linkLibs.rsp file. Could you paste the contents of CMakeFiles/avif.dir/linkLibs.rsp?

[wantehchang]

@vtorri Thank you! C:/Documents/msys2/home/vincent.torri/ewpi_64/lib/libyuv.a looks like a static library. Did you install libyuv as a static library?

@y-guyon Yannis: This shows your fix https://github.com/AOMediaCodec/libavif/pull/2425 has the desired effects, even though the IMPORTED_IMPLIB property is not set to the pathname of the import library ("the location of the .lib part of the DLL"). The import libraries, which have the .dll.a suffix instead of the .lib suffix in mingw, are used when building libavif.dll.

[vtorri]

there are both shared and static libs:

$ find ~/ewpi_64/{bin,lib} -name "libyuv*"
/home/vincent.torri/ewpi_64/bin/libyuv.dll
/home/vincent.torri/ewpi_64/lib/libyuv.a
/home/vincent.torri/ewpi_64/lib/pkgconfig/libyuv.pc

the import lib of libyuv is missing though

[vtorri]

I have installed the import lib of libyuv and here is the content of linkLibs.rsp:

 C:/Documents/msys2/home/vincent.torri/ewpi_64/lib/libyuv.dll.a -lm C:/Documents/msys2/home/vincent.torri/ewpi_64/lib/libdav1d.dll.a C:/Documents/msys2/home/vincent.torri/ewpi_64/lib/libaom.dll.a C:/Documents/msys2/home/vincent.torri/ewpi_64/lib/libvmaf.dll.a C:/Documents/msys2/mingw64/lib/libm.a -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32 

the import lib of libyuv is now used

it seems that libyuv is installing the dll, but not the import lib, i had to do it by hand

[wantehchang]

@vtorri Thank you for looking into your libyuv installation. I looked at libyuv's CMakeLists.txt and researched this issue on the Web. I found a relevant StackOverflow article: https://stackoverflow.com/questions/77826068/keep-cmake-from-from-installing-the-import-library-when-installing-a-shared-libr

Based on that StackOverflow article and libaom's build/cmake/aom_install.cmake file, I think we can fix this by adding ARCHIVE DESTINATION lib to this install() command in libyuv's CMakeLists.txt:

install ( TARGETS ${ly_lib_shared} LIBRARY              DESTINATION lib RUNTIME DESTINATION bin )

Could you please give this a try? (See the patch below.)

I also have a question. The title of this issue says "Can not cross-compile for Windows", but I see Windows drive letter C:/ in the pathnames of your build log, so it looks like you are on a Windows computer. Are you cross-compiling (on a Linux or Mac computer) for Windows?

Here is the patch for libyuv's CMakeLists.txt:

about cross compilation, here are the explanations : i (cross-)compile with msys2 + mingw, with a cross compilation file. When everything works, I create a NSIS installer for a project on linux by cross-compilation in a VM (to avoid viruses). The problem arises in both cases.

I'll try the patch soon, this evening

Thank you. I have submitted my patch to the libyuv project for approval: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5837740

[vtorri]

about libyuv, failure with file not found in cmake_install.cmake line 41 (yuvconvert not found i guess). If I replace yuvconvert with yuvconvert.exe, which exists, it works.

I know nothing about cmake, so if you can find a patch for this.

maybe also add an option to remove the build of the tool would be nice

that's why i prefer meson over cmake, no such hack should be done. You create a shared lib, the import lib is automatically built and installed.

[vtorri]

you can also propose a libyuv.pc which version is extracted from include/libyuv/version.h

[vtorri]

you can also look at https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-libyuv/cmake-mingw.patch

[kmilos]

you can also look at ...

Yep, definitely the right way to do it, and should be upstreamed.

you can also propose a libyuv.pc

Also created in https://github.com/msys2/MINGW-packages/tree/master/mingw-w64-libyuv and should be upstreamed.

@vtorri @kmilos Thank you both for your comments.

My patch for libyuv has been merged: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5837740

@vtorri Could you please confirm whether it fixed the libyuv.dll.a installation problem for you?

The mingw fix for the libyuv.dll.a installation problem will break the installation of libyuv.so on Unix platforms, if I understand it correctly. So we need to use my patch.

The mingw fix for the yuvconvert installation problem looks correct to me, so we should be able to use that fix.

[kmilos]

The mingw fix for the libyuv.dll.a installation problem will break the installation of libyuv.so on Unix platforms, if I understand it correctly. So we need to use my patch.

Indeed, the full cross-platform fix is to specify all of the LIBRARY, ARCHIVE, and RUNTIME for a shared object.

[vtorri]

@wantehchang libyuv.dll.a is indeed installed.

it remains the yuvconvert issue.

[wantehchang]

@kmilos @vtorri Thank you for reviewing my fix for the libyuv.dll.a installation problem and verifying that it works.

I will try to upstream the fix for the yuvconvert.exe installation problem today or tomorrow.

[wantehchang]

I sent a patch to the libyuv project for for the yuvconvert.exe installation problem: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5840469

@kmilos To upstream the libyuv.pc fix in mingw, it would be cleaner to have the original author submit a patch (changelist) to the libyuv project. Alternatively, if you know who the author is, I can try using git --author= to upstream the fix for the author.

[vtorri]

your patch was merged. It works:

[ 96%] Linking CXX executable yuvconstants.exe

[ 98%] Linking CXX executable cpuid.exe

[100%] Linking CXX executable yuvconvert.exe

[100%] Built target yuvconstants

[100%] Built target cpuid

[100%] Built target yuvconvert

Install the project...

for libyuv.pc, the last commit was a rename:

[wantehchang]

@vtorri Thank you for testing my libyuv patch! I will try to write libyuv.pc independently.

@kmilos Could you remove the following three lines from mingw-w64-aom/PKGBUILD?

  if [[ "${CARCH}" == "aarch64" ]]; then
      extra_config+=("-DCONFIG_RUNTIME_CPU_DETECT=0")
  fi

Runrtime CPU detection works now for aarch64.

[kmilos]

Runrtime CPU detection works now for aarch64.

Done, thanks. Might take some time to propagate...
