compile POCO undefined reference to `__sync_add_and_fetch_4'

[CER]

Hello

I am trying to install Poco 1.4.3, downloaded today, on a Centos 5 linux box.
I did:
./configure --omit=Data/MySQL
gmake -s

and got the following error:

Code: Select all

I am stuck here without any idea on what to do next

Thanks!

Seems that your compiler does not support the GCC built-in atomic functions. As a quick workaround, comment-out line 50 (#define POCO_HAVE_GCC_ATOMICS
) in Foundation/include/AtomicCounter.h and rebuild Foundation.

Hello,

We are also seeing this message. The gcc version we are using is gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-46), and I know that the poco code says that this version should be ok. Is this something that will be corrected? What other information would be helpful for you regarding this problem?

I've already did the work around to move past this issue.

Thanks,
Peter
