How to build as static libary

[MrPlatnum]

I modified the build script found in build/linux/aarch64 like this:

# Run this from within a bash shell

set +e

MPP_PWD=`pwd`
MPP_TOP=${MPP_PWD}/../../..

# toolchain detection
check_cmd(){
    "$@" >> /dev/null 2>&1
}
check_system_arm_linux_gcc(){
    check_cmd aarch64-linux-gnu-gcc -v
}

check_system_arm_linux_gcc
if [ $? -eq 127 ];then
    MPP_TOOLCHAIN=/usr/bin
    export PATH=$PATH:${MPP_TOOLCHAIN}
fi

# generate Makefile
cmake -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_TOOLCHAIN_FILE=./arm.linux.cross.cmake \
      -DHAVE_DRM=ON \
      -DENABLE_STATIC=ON \
      -DENABLE_SHARED=OFF \
      -G "Unix Makefiles" \
      ${MPP_TOP}

But it wont build the librockip_mpp as a static library. I need a static version of this library to inculde it in a static binary of ffmpeg. All help would be appreciated.

Attached patch could be referred. All the library referred should be set to static.

[MrPlatnum]

Thank you for your quick response. This does compile correctly but i unfortunatly always get the error: "ERROR: rockchip_mpp not found using pkg-config" When trying to include it in a project. Is the .pc file faulty maybe?

[MrPlatnum]

Thank you again for your response. It compiles fine as a static lib when i change the line you mentioned but as soon as try to use the lib i get a whole lot of "undefined references" like these:

And finaly the error:

collect2: error: ld returned 1 exit status
ERROR: rockchip_mpp not found using pkg-config

Do you have any idea what could be going on here?
