After burrowing through the build process with no luck, I found that the error was in the customized apachectl files, which had a version string hard coded.

Certainly, there is nothing about issues from the symbol being undefined. In the output from configure and make, I see that http_request.c is compiled. You've tracked it down right there in http_request.c. You appear to be mixing versions: new mod_proxy with an older core. Something to look at in your build/install process there, perhaps! p.s. if you're updating, you might want the new 2.4.29. -- Nick Kew --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
