After some debugging,
I believe that the main problem is related to the fact
that we use msys environment (which has msys specific mounts)
to compile a mingw32 GDB executable that knows nothing about those msys
mount points!
config.h
get several entries with directories.
All but WITH_PYTHON_PATH (which is mingw32 compatible)
are msys paths:
DEBUGDIR, GDB_DATADIR and JIT_READER_DIR
but those msys pathes are not interpreted correctly by
a mingw32 executable (i.e. gdb.exe itself).
I do believe that this is an error in the mingw32 configuration
and that it should be fixed in those configuration files...
As an example I tried to use --prefix=/e/pas/fpc-2.6.0
msys /e/ corresponds to e:/ in mingw32,
but
(gdb) py print gdb.PYTHONDIR
e:\e\pas\fpc-2.6.0\share\gdb/python
Of course, this path doesn't even exist on my computer!
If I do substitute /e/ by e:/ inside config.h
and at least get an existing path as output of (gdb) py print gdb.PYTHONDIR
The bad part is that msys doesn't have a
equivalent of cygpath utitlity, so that I proposed
a solution above, but I have no idea about how
to really implement that solution...
