A few comments: * Although building a static library with the existing object files may work, it may not be that desirable. Customarily, when building both static and shared libraries, the object files themselves will be built twice with different arguments. If you just create a static library with existing object files, you'll be using object files compiled with -fPIC and so forth. To be honest, I can't say why this is undesirable, but I know if you were building with something like libtool, you'd end up building twice: one for static, and once for shared. I realize that xerces 2.5.0's build system doesn't use libtool but instead has lots of platform-specific special case. (Perhaps libtool isn't suitable, or perhaps the build system predates it. I haven't checked 2.6.0 snapshots.) * Your diffs are on the Makefile and are generated with plain diff with on special arguments. It would be better if you used diff -u to generate a unified context diff (which is easier to read and more resilient to small changes in the files) and if you made changes in Makefile.in rather than in an automatically generated file. I'm not involved with xerces development in any way, so take my comments for what they're worth, though I hope they will be useful to you. :-) Thanks for sharing the results of your efforts! -- Jay Berkenbilt <[EMAIL PROTECTED]> http://www.ql.org/q/ --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
