Hi Partha, Chris, and Mukund, and thanks! for trying to help sort this out.
I've rebuilt babl/GEGL/GIMP in a prefix many times without any problems.
The problem started when I installed babl/GEGL/GIMP-2.8 from Gentoo
portage. For some reason GIMP from git is looking for babl in /usr
before checking the prefix.
Mukund, the build script failed with gegl saying it couldn't find babl.
Chris, I don't know how to make sense of what's in the makefile. I did
look at it.
Partha, I'm not sure how to interpret these lines:
export PKG_CONFIG_PATH=/opt/babl/lib/pkgconfig;/opt/gegl/lib/pkgconfig;$PKG_CONFIG_PATH
Babl has no dependencies and so you can build it first.
Then to build gegl, I would say
./configure --prefix=/opt/gegl LIBS=-L/opt/babl/lib CPPFLAGS=-I/opt/babl/include
because there is no "blah/babl/lib" but rather "blah/lib/babl". So I
tried the following:
./autogen.sh --prefix=/home/elle/code/gimpdefault/run
LIBS=-L/home/elle/code/gimpdefault/run/lib/babl-0.1
CPPFLAGS=-I/home/elle/code/gimpdefault/run/include/babl-0.1
and similarly for GIMP, which ended in the same GIMP "make" error
message about an undefined reference to `babl_format_get_model'.
I'm sure Partha's advice is on the right track. The babl build ends with
the following:
Libraries have been installed in:
/home/elle/code/gimpdefault/run/lib/babl-0.1
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the 'LD_RUN_PATH' environment variable
during linking
- use the '-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to '/etc/ld.so.conf'
Unfortunately I don't know the right syntax and place to implement above.
Anyway, thanks! everyone for trying to help. At this point I'll use the
"workaround" of uninstalling babl/GEGL from portage before updating
babl/GEGL/GIMP from git, unless someone knows how to implement the above
babl output.
