[Octave-bug-tracker] [bug #36477] use XDG dirs instead of HOME

[Markus Mützel]

Follow-up Comment #30, bug #36477 (project octave):

@Anonymous: Could you please report your findings at bug #54662. I was left
under the impression that Octave CLI won't start on Windows XP due to an
unknown reason.

In the mean time, I tried to link to the missing libraries by adding the
following to configure.ac:

However, the build still fails ultimately. I see the following message from
the linker (and similar ones repeatedly) in the logs:

*** Warning: linker path does not have real file for library -luuid.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libuuid and none of the candidates passed a file format test
*** using a file magic. Last file checked:
/home/osboxes/Documents/Repositories/Octave/mxe-octave-3/usr/x86_64-w64-mingw32/lib/libuuid.a
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.

*** Since this library must not contain undefined symbols,
*** because either the platform does not support them or
*** it was explicitly requested with -no-undefined,
*** libtool will only create a static version of it.


I checked that the file is there at the indicated directory. But don't know
how to proceed further.
