Hi, I was having the same kind of problem with Ubuntu 12.04 LTS.
After 3 evenings searching for a solution, I reached the online help of gcc about link option (http://gcc.gnu.org/onlinedocs/gcc/Link- Options.html) There you can read: >>>>>>> -l library It makes a difference where in the command you write this option; the linker searches and processes libraries and object files in the order they are specified. Thus, `foo.o -lz bar.o' searches library `z' after file foo.o but before bar.o. If bar.o refers to functions in `z', those functions may not be loaded. >>>>>>> So, try to do: gcc -Wall test2.c $(apr-1-config --cflags --cppflags --includes --link-ld) -o test That is to say, your C file before the APR stuff. Doing so, -lapr-1 will be at the end of the command line and the linker will find the reference, as per gcc's comment above. It worked for me. Hope this can help. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in Ubuntu. https://bugs.launchpad.net/bugs/873042 Title: unable to build against apr -- undefined reference to `apr_initialize' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/873042/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
