Sometimes you need debug Eiffel generated C codes, this is how to.

Unix

Edit $ISE_EIFFEL/studio/spec/$ISE_PLATFORM/include/config.sh and

  1. To the value of wkoptimize add the -g option.
  2. Replace the value of optimize to disable the C optimization (usually -O0) and add -g.

Once you have done that, do in your W_code or F_code directory:

  1. make clobber
  2. finish_freezing

Windows

After doing the changes below (depending on your C compiler), you can recompile your project from scratch and the debug information will be present.

MinGW

Edit $ISE_EIFFEL\studio\config\$ISE_PLATFORM\$ISE_C_COMPILER\config.eif and perform the following edits:

  1. Replace the content of optimize by -O0 -g.
  2. Replace the content of wkoptimize by -O0 -g.

Visual C++

Edit $ISE_EIFFEL\studio\config\$ISE_PLATFORM\$ISE_C_COMPILER\config.eif and perform the following edits:

  1. Replace the content of optimize' by -Od -Zi -MT.
  2. Search and replace all occurrences of -NODEFAULTLIB:libc by -NODEFAULTLIB:libc -DEBUG.


Start debug C codes in Visual Studio

Now you can attach the Eiffel process in Visual Studio and debug. Don't forget to catch all exceptions in Visual Studio.

If you want to debug Eiffel generated DLL's C codes, when coping the DLL, you must copy the ".pdb" with the DLL together since ".pdb" file contains debugging information for Visual Studio.
