[Qucs-devel] I have a problem with GDB debugger (Qucs master source code)

[Sabeur L. <laf...@gm...>]

Hello everyone,

I started recently to work on the master version of Qucs in the purpose of
adding new elements to Qucsator (such as a winding).

I downloaded the source code (master), installed dependencies and compiled
everything as described in the *CMakelists.txt* and building instructions
Qt Creator on Windows.

When trying to use the debugger (*GDB*) in order to check how the simulator
works, it works only when breakpoints are set in the main function (file
*ucs.cpp*). It ignores all breakpoints set outside that file.

For example (see screen capture here: *http://imgur.com/IeqRQIx
<http://imgur.com/IeqRQIx>*):

   - The debugger stops in breakpoint at the line *232 *(*ucs.cpp*).
   - When *F11 *is hit to step into *in->netlist()* function, the debugger
   moves directly to line *238 *in the same file.
   - The instruction at line *91 *in file *input.cpp* is ignored


The same thing happens with all the other files.

My configuration is as following:

   - Windows 7 Home Premium (64-bit OS)
   - Qt Creator 3.5.1
   - Qt 4.8.6
   - MinGW 4.9.2 32 bit
   - GNU gdb 7.8 for MinGW 4.9.2 32 bit


The project dependencies are the same as given in
*https://github.com/Qucs/qucs/wiki/Build-Windows
<https://github.com/Qucs/qucs/wiki/Build-Windows>*

Please, notice that I'm still a beginner with Qt platform and GNU
development toolchain.

I have already forced debug mode by adding SET(CMAKE_BUILD_TYPE Debug) to
*CMakelists.txt *and enabled the option "*Debug all children*" in *GDB
Extended* tab (Tools > Option > Debugger > GDB Extended). But nothing
worked !

My question: *How to do to debug properly the Qucs source code?*

Thank you in advance.

Regards,

Sabeur
