Re: [Playerstage-users] attempt at cross compile to gumstix

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I've been able to get player-2.0.4 and a recent CVS snapshot to both
build successfully for the gumstix.

Initially I selected player using make menuconfig for the gumstix root
directory.

The version included is rather old version I think. Modifying the
packages/player/player.mk file to use the newer version is pretty
easy.

There were a few problems to work around.
1. I needed to set the # of jobs to run simultateously to 1 under
menuconfig->Build options
2. Depending on what drivers you include, some of the library files
don't get put in the staging directory and the build fails. They've
been compiled so I just copied them to the staging directory and it
worked the second time. There's probably a cleaner fix but it worked
for me.
3. I found that the gumstix's shared library support was broken so I
just built it statically and it seems to work great. I think someone
recently posted how to fix it.
4. I haven't figured out how to do a libtool cross-compile build
required for plugin driver support.
5. I couldn't get the SWIG wrappers to compile under buildroot so I
had to build them by hand, but I got python bindings to eventually
work too. I posted here earlier how I did that.
