Comment 2 Andreas Schwab 2009-08-06 12:31:26 UTC

If you dlopen a module that depends on libpthread your app must be linked against libpthread as well.

Comment 3 Caolan McNamara 2009-08-07 08:36:57 UTC

but it is...

[do_lookup_x]$ ldd libsfxlx.so | grep pthread
	libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f52a0de0000)

[do_lookup_x]$ ldd checkdll|grep pthread
	libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fe38eadd000)

Comment 4 Andreas Schwab 2009-08-10 13:38:01 UTC

Fixed in 2.10.90-13
