Hi.
I need to debug KDevelop.
I have cloned the repo, opened it with KDevelop, wrote some code, compiled it and tried to debug.
But the breakpoints are working only within KDevelop but not inside KDevPlatform.
The breakpoints are always listed as awaiting ones.
Both are compiled with CMAKE_BUILD_TYPE=Debug.
What I am doing wrong?

Did you build in debug mode (-DCMAKE_BUILD_TYPE=debug)?

Yes.
P.S. See the updated question.

Is the kdevelop you built actually linked against your self-built kdevplatform, or do you maybe have a system one floating around? Try to check that with ldd ...

You're right.
How I should compile KDevelop to link it with mine KDevPlatform?

Edit: I was wrong, it's CMAKE_PREFIX_PATH and not CMAKE_MODULE_PATH, changed that.

You need to first compile KDevPlatform and install it to somewhere, say ~/stage.

Code: Select all

mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=~/stage ..
make install


Then append that path to CMAKE_PREFIX_PATH when configure KDevelop

Code: Select all

mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=~/stage -DCMAKE_PREFIX_PATH=~/stage/lib64/cmake ..
make install


This way cmake will find your newly built KDevPlatform. Hint: you can locally change KDevPlatform version to a higher number than the one in the system and modify KDevelop to require at least that number. Then you can be sure that you are building against the custom build of KDevPlatform.

In order to run KDevelop built this way, you have to specify various paths

Code: Select all

env QT_PLUGIN_PATH=~/stage/lib64/plugins LD_LIBRARY_PATH=~/stage/lib64 XDG_DATA_DIRS=~/stage/share:$XDG_DATA_DIRS ~/bin/kdevelop

Mmm, I'm using KDevelop 5 build with kdesrc, is there an other way?

Solved by adding cmake build type=Debug to kdesrc-build.
