ffmpeg freetype2 on msys2

[alicera]

Describe the issue

I build https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidia-gpu/#compiling-for-windows on msys2. I already install freetype2 but it still can't find the path of freetype2

Steps to Reproduce the Problem

Follow the installation and add --enable-libfreetype.
I use --extra-cflags and --extra-ldflags to assign the path of libfreetype.
But meet the error ERROR: freetype2 not found using pkg-config and it try to use pkg-config to find freetype2 .pc file

I try the

pacman -S mingw-w64-x86_64-freetype 
pkg-config freetype2 --libs

It is still the error.

you might need mingw-w64-x86_64-pkgconf as well, seems like configure didn't detect pkg-config

[alicera]

Using mingw-w64-x86_64-pkgconf, it is still the problem.

pacman -S mingw-w64-x86_64-pkg-config

[1480c1]

Just to make sure, you did run these through the blue MINGW64 environment and not the purple/pink MSYS environment, right? Can you upload the ffbuild/config.log somewhere like gist.github.com and paste it here?

[alicera]

I use blue MINGW64 by From the Visual Studio x64 Native Tools Command Prompt, launch the MinGW64 environment by running mingw64.exe from the msys2 installation folder

config.log

[1480c1]

Can you try running pkg-config --version and check the output of echo $?? According to FFmpeg's configure,

set_default arch cc cxx doxygen pkg_config ranlib strip sysinclude \
    target_exec x86asmexe metalcc metallib
enabled cross_compile || host_cc_default=$cc
set_default host_cc

pkg_config_fail_message=""
if ! $pkg_config --version >/dev/null 2>&1; then
    warn "$pkg_config not found, library detection may fail."
    pkg_config=false
elif is_in -static $cc $LDFLAGS && ! is_in --static $pkg_config $pkg_config_flags; then
    pkg_config_fail_message="
Note: When building a static binary, add --pkg-config-flags=\"--static\"."
fi

it sets $pkg_config to false (the false --exists --print-errors freetype2 occurs because of this) if --version errors out

[alicera]

$ pacman-key --keyserver keyserver.ubuntu.com --refresh-keys
$ pkg-config --version
0.29.2

echo $?   
0

[1480c1]

1. try pkgconf, not pkg-config, instead, it should be a better, drop-in replacement for pkg-config (subjective)
2. Did you download the latest msys2? You might want to try from there, if you still need this install, you can try some commands mentioned in https://www.msys2.org/news/#2020-06-29-new-packagers, but I personally haven't had the issue, so I can't help further with that

a return of 127 usually occurs when bash itself fails to find a command, but that shouldn't occur if pkg-config --version prints something

[alicera]

I install the newer https://www.msys2.org/news/#2020-06-29-new-packagers.

How to assign pkgconf not pkg-config?

[1480c1]

pacman -S mingw-w64-x86_64-pkgconf will install pkgconf and remove pkg-config

[alicera]

I install it and build again, but the message say ERROR: freetype2 not found using pkg-config not pkgconf

[1480c1]

Just to make sure, pkgconf --version still errors with 127?

[alicera]

$ pkgconf --version
1.7.4
$ echo $?
0

[1480c1]

Okay, try pkg-config --version, it should say the same thing

[alicera]

yes, it is the same thing.

$ pkg-config --version
1.7.4
$ echo $?
0

[1480c1]

When you run configure, does ffbuild/config.log still have a line with WARNING: pkg-config not found, library detection may fail.?

[alicera]

no find similar message WARNING: pkg-config not found, library detection may fail

[alicera]

try it again.

Do you have the method that stop use pkg-config? and use pkg-config to generate the freetype2.pc

[alicera]

# pkg-config freetype2 --libs
Package freetype2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `freetype2.pc'
to the PKG_CONFIG_PATH environment variable
Package 'freetype2', required by 'virtual:world', not found

# pkg-config freetype2 --cflags
Package freetype2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `freetype2.pc'
to the PKG_CONFIG_PATH environment variable
Package 'freetype2', required by 'virtual:world', not found

[lazka]

What does echo $PKG_CONFIG_PATH print?

[alicera]

I try to install freetype2 with msys2. But it is still fail.

 pacman -S mingw-w64-x86_64-freetype

I meet another error

Do you have another method to install ffmpeg with --enable-libfreetype?

[alicera]

pacman -S mingw-w64-x86_64-freetype

It will generate the freetype2.pc
