I plan on modifying the mod_autoindex module to fit my needs. I have Apache 2.2.22, which I installed from the MSI installer. I had the libraries included along with apache so they are official. I also use gcc 4.7.1 to build the modules. I have created and tested various other modules using gcc and they have worked fine. It seems that whenever I try to build mod_autoindex though, this error occurs: "undefined reference to `_imp__ap_subreq_core_filter_handle'". This is the commands that my IDE executes: gcc.exe -Wall -pthread -I"C:\Program Files (x86)\Apache Software Foundation\Apache2.2\include" -I"C:\Program Files (x86)\Apache Software Foundation\Apache2.2\lib" -c C:\Users\Addison\Desktop\mod_autoindex\main.c -o obj\main.o g++.exe -shared -Wl,--output-def=libmod_autoindex.dll.def -Wl,--out-implib=libmod_autoindex.dll.a -Wl,--dll -L"C:\Program Files (x86)\Apache Software Foundation\Apache2.2\include" -L"C:\Program Files (x86)\Apache Software Foundation\Apache2.2\lib" obj\main.o -o mod_autoindex.dll "C:\Program Files (x86)\Apache Software Foundation\Apache2.2\lib\libhttpd.lib" "C:\Program Files (x86)\Apache Software Foundation\Apache2.2\lib\libapr-1.lib" --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
