CMake with CodeLite, a general question

[caibbor]

I used cmake once a long time ago but couldn't quite figure out how to get it to acknowledge certain dependencies of my project. I ended up scrapping cmake. I'm curious now about CodeLite's cmake features. Since I already have my entire project set up and compiling in CodeLite, I thought that if I enabled cmake for the project that it would automatically geerate all the CMakeLists.txt files when I made a change to the project. It seems however that I have t manually make these files, that CodeLite will not generate them for me.

If that is the case, if I set up and enable cmake with my CodeLite project, will CodeLite ignore all the compiler/linker/etc options I've set up in the IDE?

If I add a file to a CMakeLists.txt, I then also manually have to add that to my CodeLite project?

Am I misunderstanding or is there a lot of manual synchronization I have to do between cmake and my CL project?

You should have the CMake plugin enabled by default.

It seems however that I have t manually make these files, that CodeLite will not generate them for me

Right click on the project and select CMake -> Export CMakeLists.txt

This will automatically create CMakeLIsts.txt for you that will "export" all of your codelite settings into CMakeLists.txt

Next, 'enable' cmake in the project settings (right click on the project -> Settings -> CMake)

Oh nice, I never noticed that menu before.

Compiling with cmake from the commandline: I generated a CMakeLists.txt file, created a sub-directoy called "build-debug", did the whole `cmake ..` thing which worked fine, but make throws errors about my use of C++11 features. I've verified that the CMakeLists.txt contains -std=c++11 in both CMAKE_CXXFLAGS and CMAKE_LDFLAGS

Try and run the generated Makefile (the one generated by the CMakeLists.txt that was produced by the CMake plugin) from the command line like this:

Code: Select all

make VERBOSE=1

This will show what flags are actually passed to the compiler (from the CMakeLists.txt I see that you are passing -std=c++11)

[caibbor]

the -std=c++11 flag doesn't seem to be anywhere in the output. in fact, it seems like none of them are being used.

Try removing the build-debug/CMakeCache.txt and re-compile the project. Maybe something with CMake's cache ...

I will see if there are other ways to pass the flags

[caibbor]

did a `rm -rf` on the build-debug dir, deleted the CMakeLists.txt and regenerated via CodeLite, made a new dir, did the cmake .. etc etc, same problem.

I am using cmake version 2.8.11.2

[eranif]

Try with latest git head. It should be fixed - I did a lot of improvements to the CMake plugin during the weekend
