Building on an up2date archlinux aarch64 fails in building/configuring ffmpeg:

I am building with the default instructions:

cmake -DADDONS_TO_BUILD=inputstream.ffmpegdirect -DADDON_SRC_PREFIX=../.. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../../xbmc/build/addons -DPACKAGE_ZIP=1 ../../xbmc/cmake/addons
make

I know there are several messages about building issues with attached PKGBUILDs but none of them are working.
I also tried with and without LTO but this makes no difference.

Nettle and gnutls versions are very specific and need to be compatible. I don’t know much about arch but this is definitely something that would need to be solved in pkgbuild

[coffeinflash]

...but nettle and gnutls are downloaded during building and I guess these versions are compatible...

[phunkyfish]

On Linux they should use the system libs and not the downloaded versions

ERROR: gnutls not found using pkg-config

since arch has moved to ffmpeg 7.0 internal deps need to be used to build the addon, i have reproduced the same issue with x86_64 pc.

at least i found what causing the issue.

-lgnutls -lgmp -latomic -ldl -lnettle -lhogweed -lgmp -lgmp -lz -lbrotlienc -lbrotlidec -lbrotlicommon -lzstd

in the linked archives list above, hogweed must come before nettle ie:

-lgnutls -lgmp -latomic -ldl -lhogweed -lnettle -lgmp -lgmp -lz -lbrotlienc -lbrotlidec -lbrotlicommon -lzstd

with the above order, linker links succesfully. I dont know which make file generates this list though, sotmething in some pkgconfig but which one? nettle?
