Question

I’m having troubles trying to use wxWidgets 2.9.4 and Xcode 4.5.2, I get all sort of errors in the way.
First of all, I think I installed wxWidgets correctly, because every sample and demo run just fine. The problem is when I try to create an Xcode project.

1. When I follow the wxWidgets tutorial changing the build settings as follows:

   • Paste the –cppflags in “Other C++ Flags”
   • Paste the –libs in “Other Linker Flags” (REMOVING THE -L)

   • Change the compiler to GCC
     I get:

   • ld: library not found for -lwxregexu-2.9

     clang: error: linker command failed with exit code 1 (use -v to see invocation)

2. When I follow the http://zebratale.tumblr.com tutorial (seems more detailed to me)
   I get:

   ld: library not found for -lwx_osx_cocoau_xrc-2.9

   clang: error: linker command failed with exit cod 1 (use -v to see invocation)

I’m completely lost and I’d appreciate any help

————UPDATE————————

I just found out that it’s possible to compile it using the terminal command:

g++ -o main main.cpp ‘./../../build-cocoa-debug/wx-config –debug –cxxflags –libs’

So I guess the problem is the compiler Xcode is using. But when I change it to LLMV GCC 4.2, I get the same error (YES, as if it was still using clang)
To change the compiler I went to build settings->build options->compiler for c/c++/objective-c and changed it.

———UPDATE2—————–

Even now that I changed the compiler on Xcode the error is:

ld: library not found for -lwx_osx_cocoau_xrc-2.9

collect2: ld returned 1 exit status

Command /Applications/Xcode.app/Contents/Developer/usr/bin/llvm-g++-4.2 failed with exit code 1

Answer 1

First, use --cxxflags (C++ compiler flags), not --cppflags (C preprocessor flags).

Second, why do you remove -L? Of course the linker can’t find the libraries if you remove the option telling it where they are.
