Hi all. With some effort, I've managed to get matplotlib-0.99.1.1 with
cygwin 1.7 (beta) on Windows 7. Since Google didn't turn up any
instructions specifically addressing the problems I had, maybe these
notes will be helpful to others.
- System details
- Windows 7, 32-bit, AMD Athlon II Dual-Core M300 2.00 GHz
- Full cygwin 1.7 (beta) installation, updated same day prior to
matplotlib installation
- Downloaded matplotlib-0.99.1.2.tar.gz on 12/20 from a link on the
matplotlib homepage
- $ tar -xzvf matplotlib-0.99.1.2.tar.gz -- matplotlib-0.99.1.1/ (??)
- $ python setup.py build
- get IndexError in line 908 of setupext.py
- failing to parse tclConfig.sh, tkConfig.sh correctly
- easiest solution seems to simply abort this function, causing the
script to fall back on defaults:
- setupext.py, line 904 just inside try block, insert: return None
- note one more hack later when linking tcl/tk libs
- Now 'python setup.py build' eventually fails with:
- Unable to free colormap, palette is still selected. and
- gcc: vfork: Resource temporarily unavailable
- not sure what is the root cause
- rebaseall doesn't seem to fix it
- though it seems to have caused failure via some memory error instead
- (I don't remember exactly)
- Painful solution to above:
- copy-and-paste gcc command printed by script
- command usually executes fine fine, but see exceptions below
- repeat 'python setup.py build', which will fail the same way, but
prints a new command
- rinse and repeat
- unfortunately, there are a couple dozen compiler commands
- the script takes several seconds each time
- Two cases require more than the simple copy/paste
- several commands with '-c src/xxx.cpp' fail, missing the .cpp file
- solution:
- $ cp -r src/_xxx.cpp src/xxx.cpp
- mimics function 'temp_copy()' in setupext.cpp
- files xxx.cpp are later deleted by script, using temp_copy()
- applies to: path.cpp, backend_agg.cpp, image.cpp, backend_gdk.cpp
- two commands link with -ltk8.4 -ltcl8.4
- solution:
- '-ltk8.4' -- '-ltk84'
- '-ltcl8.4' -- '-ltcl84'
- Caveat: I initially thought there was a problem with freetype2, so I
tried adding -I/usr/include/freetype2/freetype,
-I/usr/include/freetype2/freetype/config after -I/usr/include/freetype2
in compiler commands. I suppose it's possible that this actually fixed
something, but I don't think it did.
I wouldn't be surprised if there was a simpler way to get things going,
but the steps above seemed to work. After 'python setup.py install',
matplotlib seems to work as expected.
I hope this is helpful to someone. Sorry I don't have time to put
together a proper patch, but maybe someone else will have done so by the
next time I need to install it. I use matplotlib daily and I'm very
grateful to the people who put it together.
Regards,
GW
