Dear Matthias,

I think the answer is yes (I cite "ccmake .” output belop)

Is there a file which contains the full command that is used to compile a given source file? 

I tried to track back through cmakefiles manually, but I failed

Dear Mateusz,

That should do it, but you an check whether the debug compilation flags actually contain a -g, if not you can edit them

Dear Matthias.

Thank you for the reply. I did the following:

I recompiled alps using new empty build directory with "-D CMAKE_BUILD_TYPE=Debug”  in the cmake command, but still gdb produces the following:

Program received signal SIGSEGV, Segmentation fault.
0x00000001000e4468 in ?? ()
(gdb) bt
#0  0x00000001000e4468 in ?? ()
#1  0x00007fff5fbfbed0 in ?? ()
#2  0x00007fff5fbfc168 in ?? ()
#3  0x00007fff5fbfbed0 in ?? ()
#4  0x000000010004cf95 in ?? ()
#5  0x0000000104683cc0 in ?? ()
#6  0x0000000104938940 in ?? ()
#7  0x0000000000000000 in ?? ()
(gdb) quit

So no debug information.

I would appreciate any information of what I could be doing wrong. Is setting the flag ""-D CMAKE_BUILD_TYPE=Debug” enough?

I have noticed that there was some effect: for example mps_optim produces a lot more on the output (I’d say due to std::count << mps.description() << std::endl; ) , so I guess some debug option is being printed but this would be triggered by passing a proper flag like “-D DEBUG” to the preprocessor, but I am hoping for “-g” for the compiler.

Best,

Mateusz

Yes, just switch the build mode in cmake from Release to Debug

Dear All,
I would like to ask for some practical tips how to effectively debug alps applications:

Is there a way how to build alps with debug flags switched on?. I would appreciate an ability to use a debugger such as gdb to debug the alps applications code. Does the debugging logic depend heavily on a particular alps application (meaning is debugging modifications of mps_optim moreless equivalent to debugging dwa code)?

Can this debug mode be turned on using the cmake flags?

Best,
