I'm attempting to build pjsip 2.7.2 with video enabled for an embedded application.  When attempting to build, I always end up with linker errors when pj attempts to build the video tests files.  The build environment I'm using is buildroot on Fedora 27.  I have a full build log that I can post if needed.

For reference, here is my config:
./configure --target=arm-buildroot-linux-gnueabihf --host=arm-buildroot-linux-gnueabihf --build=x86_64-pc-linux-gnu --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --localstatedir=/var --program-prefix="" --disable-gtk-doc --disable-gtk-doc-html --disable-doc --disable-docs --disable-documentation --with-xmlto=no --with-fop=no --disable-dependency-tracking --enable-ipv6 --enable-nls --disable-static --enable-shared  --disable-ipp --disable-silk --with-external-srtp --enable-gpl --enable-libx264 --enable-video --with-sdl=/home/linuxbuild/build/ecos_init/ecos/output/root/host/arm-buildroot-linux-gnueabihf/sysroot/usr --with-openh264=/home/linuxbuild/build/ecos_init/ecos/output/root/host/arm-buildroot-linux-gnueabihf/sysroot/usr --enable-epoll --with-ssl --disable-oss --with-ffmpeg=/home/linuxbuild/build/ecos_init/ecos/output/root/host/arm-buildroot-linux-gnueabihf/sysroot/usr --with-bcg729=/home/linuxbuild/build/ecos_init/ecos/output/root/host/arm-buildroot-linux-gnueabihf/sysroot/usr --with-external-gsm --disable-opencore-amr --with-external-speex

[email_sig_centry_release]

For anyone interested, I've solved the issue.  What was happening is that the build wasn't actually replacing the shared library files that were being produced from the build.  Once I went in and manually removed the old files from /home/linuxbuild/build/ecos_init/ecos/output/root/host/arm-buildroot-linux-gnueabihf/sysroot/usr everything worked.  I'm not sure if this is a pjsip build bug or an implementation issue with buildroot that was causing the shared libraries to not be replaced.
