Recently I had the opportunity to port "Adventure Game Studio" (http://drevil.warpcore.org/ags/) to Linux. I've been statically linking all the libraries to avoid the C++ ABI issues since it is not an open source game. Under RedHat 8.0, the statically linked binary I made worked perfectly, it also worked under Debian Woody 3.0, and other distributions. Under RedHat 9 when I compile the static binary from source and then run it, it just spuriously aborts for some reason, running it through gdb reveals this process: (gdb) file ags Reading symbols from ags...done.

Program terminated with signal SIGABRT, Aborted. The program no longer exists. (gdb) Now the *really* weird part is that this statically linked binary will run just fine on Debian Woody 3.0, but it won't run under RedHat 9, that platform I compiled it on! Dynamically linked version of the executable also work just fine as well. I'll be glad to share what linking process I use if that will help. But this is a serious issue for me as it's preventing me from making another release of the game engine. On a side note, I'm seeing this same issue when compiling the latest version of subversion from the svn repository. *ANY* constructive suggestions would be appreciated. -- Shawn <drevil@xxxxxxxxxxxx> http://www.warpcore.org/
