I built rootfs with opengl and QT without problem. (The compiled examples
of QT also run in ubuntu without problem)
But when I tried to run these qt examples in created rootfs, it gives "file
not found" error. (I both tried these examples static and shared compiled.)
Then I cheked the dependency of application, you can see results below.
The /usr/lib folder has the lib files but in a .a format.
For example libm.a is exist but libm.so absent.
How can I solve this problem?
thanks,
Ozgun

Can you show exactly how this error appears? If it appears when you try
to run the application, then it usually means that the kernel can't
find your dynamic library loader.
I never use Buildroot to generate a filesystem in which I'm chroot-ing.
If the target architecture is the same as the host, it should work, but
there might be issues, it's not the common use case for Buildroot
(usually, you take the generated root filesystem image and put it on a
target device).

The shared versions of the C library and related libraries (libm, etc.)
are in /lib, not in /usr/lib.

I used chroot environment to get the error log easily. Normally I use the
rootfs in a embedded pc.
But the error message are same.
When I try to run application (./affine), it gives "file not found" error.
When I check the dependency (ldd affine) below log occurs. (even the file
compiled static.)
It looks like dynamic library loader finds the .so files under /lib but
couldn't find .so files under /usr/lib
I used crosstool glibc instead of uclibc toolchain and the problem solved.
(with same etc folder)
But I want to know what cause this problem.
thanks,
Ozgun
