Re: [Plplot-devel] Space in full pathname issues

Hi Chris,



Thanks for the warning - I will not try to test this feature on Cygwin then.



Regards,



Arjen

cygwin doesn't handle install directories with whitespace fully or at all.

At any rate, you would not be able to determine if a failure was from
a bad fix at the plplot level or the underlying cygwin and the white space.
Cheers,
Chris

Just a short update: I locally adjusted the diff commands in test_diff.sh.in<http://test_diff.sh.in>, as these were causing trouble because of spaces in the path name. While doing that I found that CMake finds a "diff" program that is most probably not compliant with the Linux/POSIX/... conventions. So the report about the differences concerns all examples.

The way around that is to force the use of the MinGW-w64/MSYS2 diff program. There may be more such surprises.

And then there is the matter of the mysterious "D?" directory created by ctest. It is not the consequence of anything obvious that I could detect.

Especially this latter issue hinders progress in the comprehensive tests, as it causes a premature end (find is not able to handle this directory and thus an error is thrown). So slow progress for the moment.

Arjen
