Compiling gstreamer with new glib version

Question

I have CentOS 6.7 installed. I need to compile GStreamer 1.4.5 (or any 1.x) because CentOS distribution has GStreamer 0.10. GStreamer 1.x requires GLib2 >= 2.32 or so, but CentOS has 2.28.8. Therefore I compiled GLib 2.44.1 using specific location /usr/mylibs (as --prefix param).

ll /usr/mylibs/lib

Now I'm trying to compile GStreamer 1.4.5:

export GLIB_CFLAGS="-I/usr/mylibs/include/glib-2.0 -I/usr/mylibs/lib/glib-2.0/include" && export GLIB_LIBS="-L/usr/mylibs -L/usr/mylibs/lib/glib-2.0" && export GIO_CFLAGS="-I/usr/mylibs/include -I/usr/mylibs/include/gio-unix-2.0" && export GIO_LIBS="-L/usr/mylibs -L/usr/mylibs/lib/gio" && export PYTHON=/usr/mylibs/bin/python
./configure --prefix=/usr/mylib
or
./configure 
make

And it works until this error:

What have I missed? Please help.

Answer 1

I encountered the same problem on my CentOS 6.3 VM. I was attempting to build GStreamer 1.4.5 against glib 2.32.4. As shown in this message thread it would appear that the incorrect libraries are being linked when you attempt to build (not the 2.0 ones!) Rather than explicitly defining the directory paths in GLIB_CFLAGS you could use PKG_CONFIG_PATH.

Locate the pkgconfig directory and ensure packages you have installed reside in there (like glib-2.0, gobject-2.0, gthread-2.0, etc.) (On my computer my path was: /usr/local/lib/pkconfig/.) I noticed in your directory listing that you have provided you do indeed have pkgconfig.

First, export the variable, then configure, and finally make:

export PKG_CONFIG_PATH=/usr/mylibs/lib/pkgconfig/ ./configure make

GStreamer should now build correctly.

Answer 2

You seem to be misunderstanding how the *_LIBS environment variable works. It should contain the flags needed to link to glib; something like "-L/usr/mylibs/lib -lglib-2.0" should work.

The -L… flag gives the linker an additional place to look for shared libraries (i.e., libglib-2.0.so), but in your flags you've given it one directory above what it needs (/usr/mylibs) and a subdirectory (/usr/mylibs/lib/glib-2.0). The -l… flag tells it what specific library to look for, but you completely omitted it.
