libvpx Dependencies

Required

yasm-1.3.0 or NASM-2.15.05, and Which-2.21 (so configure can find yasm)

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/libvpx

Installation of libvpx

Install libvpx by running the following commands: 

sed -i 's/cp -p/cp/' build/make/Makefile &&

mkdir libvpx-build            &&
cd    libvpx-build            &&

../configure --prefix=/usr    \
             --enable-shared  \
             --disable-static &&
make

To test the results, issue: LD_LIBRARY_PATH=. make test. The test suite downloads several files as part of its test process.

Now, as the root user: 

make install

Command Explanations

sed ... : This command corrects ownership and permissions of installed files.

mkdir libvpx-build && cd libvpx-build: The libvpx developers recommend building in a dedicated build directory.

--disable-vp8: This switch prevents building of VP8 codec support.

--disable-vp9: This switch prevents building of VP9 codec support.

--disable-static: This switch prevents installation of static versions of the libraries.

LD_LIBRARY_PATH=.: This is needed for the testsuite to use the just built library.
