Gdb don't work with gfortran compiler
Garibaldi:
Hi all,
I apologize for my bad english...
Normaly I use linux, and in linux I have started to use code::blocks...It is a very good program....
But in this moment I must use windows. I have to write a fortran program that receve data file generated by program that work only on Windows OS...
In linux can compile and degug any fortran program.
Instead in windows I can only compile program, but I can't debug it.
On my Pc I installed code::bock 8.02, Cygwin (but I have also MinGW32), gfortran and plug-in code::block fortran....
I have configurated the toolchain for fortran compiler.
I can add breakpoints but when debug the program, it run fully without stop.
I thought perhaps replacing gdb with a new version the problem end, but I obtained the same result.....
I'm not expert and so I don't know what to do.
I post the log:

Thanks
Look your news
oBFusCATed:
Can you debug your program with gdb directly (starting gdb from cmd line)?
Garibaldi:
I could try, but I don't know how to do.
I tryed to compile and debug my program in command line in this way:
gfortran myprog.f90 -g -o myprog.exe
And then:
gdb myprog
But in this way I work with gdb installed with cygwin. This gdb version is 5.0.
It is quite old and maybe it isn't compatible with fortran.
Infact in gdb window I don't read fortran code but assembly code.
I downloaded a new version of binary gdb (gdb 7.1)
I try to run this, but I don't know how use it.
This is the result in cmd:

Thank you for the answer
oBFusCATed:
Read the manual: http://sourceware.org/gdb/download/onlinedocs/gdb/index.html
Or try to find some tutorials.
The other thing you could do is to copy the commands from the debugger's debug log, you've pasted.
Garibaldi:
Thank you very much oBFusCATed.
I read few pages of gdb manual for understanding the basic function and then I try to write similar istruction of the debugger's debug.
In this way I be able to debug my program.
But it is very singular that I can debug programs in cmd and I can't with code::blocks.
If you exame the debugger window you can see this error:
break "C:/Documents and Settings/Utente/Documenti/prov/EnricoCaruso/Programmi fortran/read_file/debugging/deb.f90:8"
No source file named C:/Documents and Settings/Utente/Documenti/prov/EnricoCaruso/Programmi fortran/read_file/debugging/deb.f90 in loaded symbols.
Program can't add the breakpoint because It doesn't find the source. But the source exist.
For this reason the program run fully, because C::B can't add any break.
I don't know because debugger don't work.
Could be the plug-in not work well in windows?
In linux I use the same plug-in and I never have problems.
I say that because I try to use no plugin. I add manualy compiler, group of file associated with compiler (.f .f90 ecc). And in this way with the same toolchain (and so with the same .exe) I can compile, debug and run any program.
The only problem was that there wasn't a default highlighting for fortran. But I resolve this replacing the directory lexar positioned in C::B fortran plug-in with the same folder positioned in the install directory of program C::B.
I wait a few day before mark this discussion how solved.
I want to be sure I solved the problem before close the conversation.
Thank you
