There doesn't seem to be anything missing...

~ $ ldd ~/BOINC/projects/gene.disi.unitn.it_test/gene_pcim_v1.03_linux32__sse2
linux-gate.so.1 => (0xb77ca000)
libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xb7768000)
libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xb774c000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb759b000)
/lib/ld-linux.so.2 (0xb77cc000)
~ $

I noticed the 2.6 here:-

~ $ ldconfig -p | grep libc.so.6
libc.so.6 (libc6, OS ABI: Linux 2.6.24) => /lib/i386-linux-gnu/libc.so.6

is this right?

The libc version is 2.19.

Any ideas welcome.
