toolchain problem:wrong path in libSDL.la

Hi,

I'm using recent version 2009.11 and I've added SDL package to my configuration.

My br installation is at /mnt/ext3data/buildroot/

but br creates a wrong path of libdir in libSDL.la (/mnt/ext3data/buildroot/output/build/SDL-1.2.14/build/libSDL.la
resp. /mnt/ext3data/buildroot/output/build/staging_dir/usr/lib/libSDL.la):
--- cut ---
# Libraries that this one depends upon.
dependency_libs='
-L/mnt/ext3data/buildroot/output/build/staging_dir/usr/lib /mnt/ext3data/buildroot/output/build/staging_dir/usr/lib/libiconv.la -L/mnt/ext3data/buildroot/output/build/staging_dir/lib -lm /mnt/ext3data/buildroot/output/build/staging_dir/usr/lib/libts.la -ldl
-lpthread'
# Directory that this library needs to be installed in:
libdir='/mnt/ext3data/buildroot/output/build/staging_dir/usr/mnt/ext3data/buildroot/output/build/staging_dir/usr/lib' --- cut ---

Of course the correct path at my machine is '/mnt/ext3data/buildroot/output/build/staging_dir/usr/lib' That makes it impossible to link applications that require the SDL lib, it leads to an linker error: i.e. 'could not find SDL lib'

I checked older br versions , but same problem. Also an update (I switched to newer versions in br scripts) of SDL lib didn't help it nor update of libtool (as far as I understood that creates the *.la files !?).

BR,
Jens

Hi Jens,

Jens a ?crit :

please find attached here a patch that can probably solve your problem. Sorry but I didn't take time yet to submit it to BR team.
http://armadeus.git.sourceforge.net/git/gitweb.cgi?p=armadeus/armadeus;a=blob;f=patches/buildroot/078-sdl-correct_libdir_path_in_libSDL.la.patch;h=c455834241d222b72865032c333c83630bd571b0;hb=HEAD

Hope it will help you...

Hi Julien,

Thank you very much! Yes in staging_dir libdir of libSDL.a has fixed now. But your patch is just a workaround because in build dir of SDL the path will be still wrong.

Could not find it as known bug in recent buglist, hence I supposed to write a new bug report, but I still don't have an account.

BR,
Jens

Hi Jens,

Jens a ?crit :

and why do you need libSDL.la from SDL build dir ? Shouldn't you use staging_dir content to link your application against SDL (or other .so) ?

If think it's an SDL cross-compiling problem (libtool?). When configuring SDL with --prefix="/usr" I think you will have a correct libdir in libSDL.la, but in that case SDL would try to install itself in /usr/ of your host.

So I will propose my workaround unless someone has a better idea...

Regards,
Julien
