DirectFB Fails with wrong File Format erro rfor libsysfs

Hi all,

I am trying to build arm 926ejs toolchain with latest buildroot snapshot .
while compilling directfb I get error as mentione below libsysfs in wrong file format. i checked $(BUILD_DIR)/staging_dir/usr/lib & libsysfs.[a/so] exists their. but the make directfb must be from /usr/lib/.

kindly help me to resolve the same. i have attached the Directfb configure
erro & also my Buildroot config details & directfb config.log details

Regards

Hi All,

After i renamed the libsysfs.* from my root /usr/lib/libsysfs to something
else, compileation continued. but later got struct at

cp -dpf /home/guru/project/original/toolchains/buildroot/build_arm/staging_dir/usr/lib/libdirect* /home/guru/project/original/toolchains/buildroot/build_arm/staging_dir/usr/lib/libfusion* /home/guru/project/original/toolchains/buildroot/project_build_arm/uclibc/root/usr/lib/
cp: cannot stat `/home/guru/project/original/toolchains/buildroot/build_arm/staging_dir/usr/lib/libdirect*':
No such file or directory
cp: cannot stat `/home/guru/project/original/toolchains/buildroot/build_arm/staging_dir/usr/lib/libfusion*':
No such file or directory
make: *** [/home/guru/project/original/toolchains/buildroot/project_build_arm/uclibc/root/usr/lib/libdirectfb.so] Error 1

I looked through the $(BUILD_DIR)/staging_dir/usr/lib & found that the
files are actually copied to $(BUILD_DIR)/staging_dir/lib/. Find attached the details of directfb.mk file & let me know what changes i shld make.

I had a similar error in another package some time ago and found out, that libtool expands the -l... (In this case the -ldirectfb) to the first library-file it finds. Unfurtunatly It searches the system-path first. That time I was patching libtool to ignore the library I needed; but it was a verry dirty hack.
Maybe someone knows a better solution.
