Hi,

how can I install mlt, mlt++ and kdenlive to some non-standard prefix while keeping the normal installation in /usr/local/ intact? I installed mlt into ${HOME}/local-mlt/ and am now trying the same with mlt++ using the following lines in a small installer script:

PKG_CONFIG_PATH="${HOME}/local-mlt/lib/pkgconfig":${PKG_CONFIG_PATH}

./configure --prefix=${HOME}/local-mlt++/ && make && make install

It seems to work fine, but ldd on the mlt++-libs shows:

~ $ ldd local-mlt++/lib/libmlt++.so

        linux-vdso.so.1 =>  (0x00007fffa53fe000)

        libmlt.so.1 => /usr/lib/libmlt.so.1 (0x00007f599cf07000)

        libmiracle.so.1 => /usr/lib/libmiracle.so.1 (0x00007f599ccf9000)

        libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/libstdc++.so.6 (0x00007f599c9f5000)

        libm.so.6 => /lib/libm.so.6 (0x00007f599c774000)

        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f599c566000)

        libc.so.6 => /lib/libc.so.6 (0x00007f599c226000)

        libdl.so.2 => /lib/libdl.so.2 (0x00007f599c022000)

        libpthread.so.0 => /lib/libpthread.so.0 (0x00007f599be07000)

        libvalerie.so.1 => /usr/lib/libvalerie.so.1 (0x00007f599bbfb000)

        /lib64/ld-linux-x86-64.so.2 (0x00007f599d383000)

So obviously mlt++ looks only into the standard paths for the mlt libraries. Am I missing something or should I hack into the Makefiles to pass an rpath option to the linker?

Edit:

See https://sourceforge.net/tracker2/?func=detail&aid=2584884&group_id=96039&atid=613416 for a quick hack that worked for me.

I use the LD_LIBRARY_PATH trick with no problems. Type this on a terminal window to learn more about it.

man ld.so

In the top level of your MLT source directory view the setenv script for other MLT evironment variables that tell it where to lookup plugins and data files.
