thread Support:

i have setted the callback in the ssl code, like the example in "crypto/threads/mttest.c" .


question:
but the same code in the other machine2[Linux ph-suse 2.6.27.19-5-default #1 SMP 2009-02-28 04:40:21 +0100 x86_64 x86_64 x86_64 GNU/Linux] is success。 i used the 'ldd' to check whether the libs is different in machine2, but they are same.


who can help me? thank you!
