Code::Blocks WxWidget error - No Target! You should use wx-config program for compilation flags?

Question

I can't get the default WxWidget template that comes with Code::Blocks to compile. The error I receive is error "No Target! You should use wx-config program for compilation flags! (amongst others)

Google led me to some links but I can't seem to figure it out

One similar thread I found; http://forums.codeblocks.org/index.php?topic=10122.0

"The problem is moste likely, that you have wxwisgets installed in a non standard directory tree."

wx-config --list

Reports:

wx-config --prefix=/opt --list

Reports:

Is this correct? I can't tell.

Another similar thread; http://www.justlinux.com/forum/archive/index.php/t-105554.html

The person in that topic ended up adding g++ 'wx-config --cflags' -o wxTest wxTest.cpp as a compilation/linking flag but I tried adding that to "Linker Settings -> Other linker options" in Code::Blocks and it doesn't seem to do anything.

Includes:

I find this whole linker business extremely confusing and I can't figure out where I'm going wrong on this.

I understand that the answer is right in front of me in one of those threads, but due to my inexperience I can't seem to apply the solutions to my situation. I gave up after 1 hour of trying random things.

Answer 1

I have no experience with codeblocks, but wx-config gives you the flags and libraries you need to work with wxWidgets.

wx-config --cxxflags

will give you the compiler flags, like include directories and #defines. On my system this gives me

-I/usr/local/lib/wx/include/gtk2-unicode-2.9 -I/usr/local/include/wx-2.9 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXGTK__ -pthread

On the other side

wx-config --libs

will give you the library path and libraries for linking. Which on my system results in

-L/usr/local/lib -pthread   -lwx_gtk2u_xrc-2.9 -lwx_gtk2u_html-2.9 -lwx_gtk2u_qa-2.9 -lwx_gtk2u_adv-2.9 -lwx_gtk2u_core-2.9 -lwx_baseu_xml-2.9 -lwx_baseu_net-2.9 -lwx_baseu-2.9 

So you could probably just use the outputs of those commands and enter them to the respective options in Code::Blocks.

An alternative could be to use CMake to generate a simple wxWidgets application, let it build the Code::Blocks project and then hijack that for your own application.
