CodeLite IDE

Hi!

I want to start building a little Programm with an opengl canvas. I've created a standard GUI Project for wxcrafter and pulled the gl canvas in a sizer.
When I start the build I get this error message.

/bin/sh -c 'make -j8 -e -f Makefile'
----------Building project:[ test1 - Debug ]----------
/usr/bin/clang++ -o ./Debug/test1 @"test1.txt" -L. -L/Users/rhoeger/Documents/src/wxWidgets/tags/WX_3_0_1/build-debug/lib -framework IOKit -framework Carbon -framework Cocoa -framework AudioToolbox -framework System -framework OpenGL -lwx_osx_cocoau-3.0

clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [Debug/test1] Error 1

How can I solve this issue?

Hi,

Is your wxWidgets compiled with OpenGL support?

Eran

Hi!

I was not shure so I've compiles wxwidgets with the flag --with-opengl but in the subsumption of the configuration it states 'open gl support: no'.
Btw. with the option on I get the same error.
The wxwidgets opengl sample works!

Try to compare the link lines between codelite's workspace and the link line produced by the sample ( you can also paste them both here and I might help you with this)

Hi!

Sorry for the late delay! I was busy at work.
Here are the lines if I call the make function of the make demo isosurface from wxWidgets

The demos all working. So OpenGL should'nt be the problem.
Hope you can help me.

Thanks!

I can see several differences between the makefile and the one produced by codelite, for example: and this one:
Try adding them to the linker options (mainly the last one): right click the project->settings->common settings->linker
Search for the line that looks something like this: and change it to: Eran

Hi!

I just want to let you know that the tip you gave me, worked! I'm currently very busy. Hope I have in the next weeks more time
to get some steps further. Thanks!


Sincerely
