[directfb-users] Re: DirectFB crosscompile - How ?

[Jose Miguel Goncalves <jose.goncalves@inov.pt>]

I've had a similar problem when cross-compiling GTK+ over DirectFB.

My suggestion:

Get rid off the .la files generated by libtool for DirectFB, to force the next 
configure step to use pkgconfig .pc files to find dependency libraries (save 
the .la files on a temporary directory, in case you need them in the future).

Then you must do one of the following:
a) patch the .pc files for DirectFB to point "prefix" to your temporary 
installation directory (in your case /source/directfb/dfb) or
b) patch the configure of your library that will use DirectFB to add 
"--define-variable=prefix=/source/directfb/dfb" to all pkgconfig calls with 
arguments "--cflags" or "--libs".

You should also set LD_LIBRARY_PATH to /source/directfb/dfb/lib. I prefer 
setting it when calling configure like this:

$ ./configure \
PKG_CONFIG_PATH=${TARGET_PREFIX}/lib/pkgconfig \
LD_LIBRARY_PATH=${TARGET_PREFIX}/lib \
--host=${TARGET} --prefix=/usr

Hope this helps,
