Dear Jon, > Is there some reason why you can't just install that? thanks for the hint - I was not aware that the -debuginfo package contains sources - I thought these just contain dwarf files or similar for stripped binaries and sources are in the -src packages. Unfortunately for MinGW debuginfo packages exist only for rather few libraries. Also I wonder if there exists something like debug info for stripped binaries in Cygwin - similar to .pdb files for MSVC. These seem to be not part of the debuginfo packages. Does this mean when I want to debug DLLs I anyway need to recompile them because the installed DLLs are stripped and there is no other way to get DLLs with debug information?
