[Xenomai-help] librt.so.1 missing

Running the test suite on the ARM board results on the message:

 error while loading shared libraries: librt.so.1: cannot open shared object
file: No such file or directory

I cannot find librt.so in any directory of the compiled kernel or the user
space. Am I missing something?

Thanks

It is part of the glibc, so should be installed by whatever you use to
generate your root file system. If you do not compile glibc, you will
find it in the toolchain directories.

So if I were to checkout glibc and compile it with the arm-unknown-linux
toolchain (the same used to compile the rest of the kernel), the resulting
libraries would be usable? Another person generated the root file system and
they aren't being very helpful.

To make this work, you have to build the glibc with exactly the same
options and the same version as the one which was used when making the
toolchain. So you are probably better off taking the compiled libraries
directly in your toolchain directories.
