Problem building matplotlib-0.87 on Linux

I tried to build matplot lib (both 0.87 and 0.86.2) on Ubuntu Linux 5.10. The
first set of error messages convinced me to install the Tcl and Tk dev
packages.

The second run of errors is just really weird, and I'm not sure how to fix it.

Thanks,
Antoine

Whatever you set to '/usr/lib/tk8.4/../' needs to be a list
['/usr/lib/tk8.4/../'] and not a string.

Hi Antoine,

I had exactly the same problem. I tracked it and found that in the
setupext.py, when I tried to print the module.library_dirs variable after the
command:
module.library_dirs.extend([o.tcl_lib, o.tk_lib])
I got:
['/usr/share/tcl/tcl8.4/../', u'/usr/share/tcl/tk8.4/../']
The string containing the tk library path is a unicode one for some reason I
do not understand. I changed then the line which fills this string. It is in
the function find_tcltk(): of setupext.py:
o.tk_lib = os.path.join(tk.getvar('tk_library'), '../')
I replaced it by:
o.tk_lib = os.path.join(str(tk.getvar('tk_library')), '../')

And that did the trick.
I really don't understand why the tcl library string is not affected by the
same problem anyway...

And that did the trick.
I really don't understand why the tcl library string is not affected by the

But this fix was committed back on Feb 2, and is included in mpl-0.87.

I came across the same problem, but was able to
overcome it by setting the LANG environment
variable to "C" rather than "en_US.UTF-8"
