It makes no sense to use absolute paths in debug information, because it
would make distribution of units compiled with debug information to
other
machines impossible (or more precisely - it would be possible to
distribute them, but debugging would not work :/ ).
I was waiting for this argument, because it is totally wrong :-)
The paths on another system may be wildly different anyway.
Just take a debian vs. fedora system.
Paths are valid only on the system where the compiler/debugger are
running;
anything else is wishful thinking.
OK, I enjoy being wrong. ;-) My point is that the system where the
compiler is (was) running may be different from the system where the
debugger is running. Among others, this scenario is explicitly supported
by FPC with its parameter supporting creation of a script for linking on a
(different) host machine.
I understand the logic.
And I'd indeed wish to keep possibility of copying my compiled units to a
different machine (which may not follow the same rules for location of the
home directories, or may provide some other designated space for my work
outside of the standard home directory) while still being able to debug
the created executable there (as easily as possible - that is fulfilled by
the current situation of using relative paths within debug information,
but would be negatively impacted by a potential change to absolute paths
everywhere in FPC including specifically debug information).
At the very least I think that we should be consistent and use the same
filenames in link script and debug info ?
For all other problems: making an option telling the compiler to use only
absolute/relative paths seems like an option which can be used to cater
for all situations.
Michael.
