Subject: [Plplot-general] CMake problem with hyphen in path
Hi Alan (I guess this is your expertise) I've just tried to build plplot on a
new Windows system and I am getting problems.
After some digging I found that the issue is that my home directory (where all my libraries
are stored and where I am building plplot) contains a hyphen with a space either side.
Specifically it is C:\Users\<my_username>\Onedrive -
<my_employer>\Documents\usr\...
I would imagine I'm not the only person who has hit this problem as this is the
name that seems to be given by default when using Ondedrive for business.
This filename then interacts with the logic in cmake_link_flags - see
plplot/modules/cmake/pkg-config.cmake line 261, which replaces " -"
with ";-".
This splits all my library paths in two and obviously causes errors.
I'm not really sure what to do about this? Any suggestions?
AM:: I have the same pattern in my home directory, but I never build any software there 😊. We did
do a test with directories have spaces and IIRC, we sorted out the problems this was causing. Just
checked: I did that test in November last year and as I have the examples there, it must not have
been a problem. I do have an odd subdirectory, "d*" (where the asterisk is actually a
centred dot). That is due to trying to install PLplot, not juist build it. If the pattern you
describe causing problems and a simple directory name like "build with spaces" (the name
I used) does not, there are still some issues to solve.
@Phil:
I cannot confirm the issue on Linux. Here are the details of that test.
# Create source tree with hyphenated pathname using a symlink to actual git
repository
# cd to working directory of actual (not symlinked) repository
cd /home/software/plplot/HEAD/plplot.git
cd ..
ln -s plplot.git "plplot hyphen - .git"
cd plplot.git
# Run my usual noninteractive comprehensive test for hyphenated
# source, build, AND install trees.
# N.B. For my Debian Buster platform I like/need to test
# special versions of lua, libLASi, and qhull via setting the
# CMAKE_PREFIX_PATH environment variable, a special version of cmake
# (and ctest) via setting the PATH environment variable, and a special
# version of swig via setting the SWIG_EXECUTABLE CMake cache
# variable.
SOURCE_PREFIX="/home/software/plplot/HEAD/plplot hyphen - .git"
# This hyphenated directory does not (necessarily) have to exist before the test
# since the script deletes it (if it exists) before (re)creating it.
COMPREHENSIVE_TEST_PREFIX="/home/software/plplot/HEAD/comprehensive_test_disposeable
- hyphen"
time (nice -19 env CMAKE_PREFIX_PATH=/home/software/lua/install-5.3.5:/home/software/lasi_svn/install:/home/software/qhull/install
PATH="/home/software/cmake/install-3.13.2/bin:$PATH" "$SOURCE_PREFIX"/scripts/comprehensive_test.sh --prefix
"$COMPREHENSIVE_TEST_PREFIX" --cmake_added_options "-DUSE_INCRTCL_VERSION_4=ON
-DSWIG_EXECUTABLE=/home/software/swig/install/bin/swig" --build_command "make -j16" --ctest_command "ctest -j16"
--do_test_interactive no)
That comprehensive test completed without obvious errors or hangs (in 23 minutes
of wall-clock time on my computer with 16 hardware threads), and the results of
running the evaluation procedure for such tests that is documented in
doc/wiki_source/Testing_PLplot were perfect!
So my conclusion is that basically all the many steps we (including a
large initial effort from you) have taken over the years to
blank-proof PLplot are generally also working to hyphen-proof PLplot.
IMPORTANT CAVEAT:
One thing these Linux tests do not do is use external libraries with
blanks or hyphens in their pathnames so my working hypothesis for the
reason for the symptoms you reported above is you
ran into that kind of issue on Windows.
Here are my suggestions for investigating such issues in a straightforward
and systematic way on MSYS2 (our best platform for testing Windows).
(i) Install MSYS2 (including all PLplot prequisites) following the
clear directions in the MSYS2 wiki that I referenced before. Use an
MSYS2 install prefix with no hyphen or blank issues for now.
(ii) Run a comprehensive test on MSYS2 with source, build, and install
trees that are space and hyphen free. This will likely take several
iterations to get right, but if you send me the report tarball that is
generated each time, that should provide me with enough information to
debug any problems you encounter on this platform (which will likely
be MSYS2 installation issues since Arjen has debugged virtually all
the PLplot issues on this platform). And, of course, once you also
have complete success with this step that doubles our developer
support for this important Windows platform.
(iii) Repeat the last successful blank- and hyphen-free test, but this
time using blanked and hyphenated (as in my test above) source, build,
and install trees for the test. I expect this test to work for you
since it works on Linux.
(iv) Repeat (i) with the MSYS2 install prefix with " - " in its name
and repeat (ii). I assume from your results above that (ii) will not
work for this case since the (MSYS2) libraries needed by PLplot will all have " -
"
in their pathname. Note, the report tarballs generated by (ii) should
be a large help as I attempt to fix the "external library blank and
hyphen" issues in our build system that are found by this test. Once
(ii) works with " - " in the MSYS2 prefix then try (iii), but I think
that will work once (ii) works.
Good luck, and let me know how it goes with the above steps.
