Pick any non-trivial program and when compiled on one system it may not run another. You may have different library versions, for example. Certainly if glibc doesn't match you're going to have a problem. I tried to come up with a list of what matters for a super simple "hello world" Apache module but wasn't able to come up with a such a list. Since an Apache module isn't an executable, but rather becomes part of the Apache executable, any number of compile options could cause problems if they don't match between the two systems. You'll notice that software is generally distributed as either a) a compiled package such as an RPM or deb built for a specific version of a specific distribution or b) source code. > I wanna that whether there are differences between apxs and apxs2. It is my understanding, which may be wrong, that some distributions which have both Apache 2.x and Apache 1.3 packages available make that distinction. They call the Apache 2.x version of apxs "apxs2" so that you can easily run either, depending on which httpd you wish to compile for. It's the same tool, just renamed on some distributions. -- Ray Morris supp...@bettercgi.com Strongbox - The next generation in site security: http://www.bettercgi.com/strongbox/ Throttlebox - Intelligent Bandwidth Control http://www.bettercgi.com/throttlebox/ Strongbox / Throttlebox affiliate program: http://www.bettercgi.com/affiliates/user/register.php On Fri, 19 Aug 2011 12:22:12 +0800 david jone <davidjone2...@gmail.com> wrote: > Hello, > everyone,recently I have a problem that a apache module > developed on ubuntu with apxs2 can't work on CentOS. > The more details as follows: > 1.
