Build yara static lib with a musl-gcc for rust project

[fivlao]

I am trying to build yara static lib with a musl-gcc for my rust project. But when it is running

CC="musl-gcc"  \
CFLAGS="-I/usr/local/musl/include -I/usr/include/linux -I/usr/include/x86_64-linux-musl"  \
LDFLAGS="-L/usr/local/musl/lib -L/usr/lib/x86_64-linux-gnu -L/usr/lib/x86_64-linux-musl"  \
./configure \
  --with-crypto \
    --enable-magic \
    --enable-cuckoo \
    --enable-dotnet

it return me error "configure: error: pthread API support is required". Details output

I tried add path pthread header to CFLAGS and add path pthread static lib to LDFLAGS but it did not help

About CFLAGS:
/usr/local/musl/include - path to jansson headers
/usr/include/linux - path to libmagic headers
/usr/include/x86_64-linux-musl - path to pthread header (it did not help 🥲)

About LDFLAGS:
/usr/local/musl/lib - path to jansson static lib
/usr/lib/x86_64-linux-gnu - path to libmagic static lib
/usr/lib/x86_64-linux-musl - path to pthread static lib (it also did not help 😭)

docker build command: docker build . -f ./Dockerfile -t yara-build-image:latest

Maybe who knows how to fix this problem and build yara static lib
