Further google research gave me this thread: http://www.unix.com/aix/51279-error-when-compile-httpd-2-2-8-aix-5-2-a.html Which contains a posting that indicates there is a separate AIX RPM for libgcc, which contains libgcc_s. I went to the IBM site (http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/ezinstall.html) downloaded and installed the libgcc RPM. Following that, I re-ran configure, and was able to successfully build apache. Thanks for your help. -tony -----Original Message----- From: Eric Covener [mailto:covener@xxxxxxxxx] Sent: Monday, August 02, 2010 5:27 PM To: users@xxxxxxxxxxxxxxxx Subject: Re: 2.2.15 Build failure on AIX 6.1 > collect2: library libgcc_s not found good luck with gcc, I've only used xlc on AIX for httpd. Seems like you're either missing part of gcc or the Apache build isn't able to find it. This is the bit that gets incorporated into apps built with the gnu toolchain. -- Eric Covener covener@xxxxxxxxx --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
