- Installed cygwin from http://www.cygwin.com/ by downloading and running setup.exe. In the setup, I chose to install everything.
- Installed swig1.1-883, following most of the instructions from the website: http://www.creatis.insa-lyon.fr/~bellet/creatis/cygwin/. The instructions include removing the newer version of swig, unpacking swig1.1, and installing a patch.
- Searched the web for the files cygdpstk-1.dll and cygdps-1.dll (missing by default in cygwin) and put these in /usr/X11R6/bin. These files were obtained using a link on the website: http://comments.gmane.org/gmane.os.cygwin.xfree/16493. (I found out about these required dll's after I already built oof2 and ran it on cygwin. It gave a very cryptic error message that said "No such file or directory" associated with loading oofimagecmodule.dll. After a lot of tests, it dawned on me that that the python module itself wasn't missing, but that some of the dll's that it linked to were. I used cygcheck (which works like ldd) on oofimagecmodule.dll to show what other dll's it depends on.)
- Made a small change in oof2setuputils.py, passing in the argument string "pkg-config.exe" instead of "pkg-config" in check_exec, which is called by the method pkg_check. (The command "whereis pkg-config" would reveal "pkg-config.exe" as the full name of the executable under cygwin.)
- Made some changes to SRC/image/DIR.py: def set_clib_flags(c_lib): import oof2setuputils if oof2setuputils.check_exec('Magick++-config'): oof2setuputils.add_third_party_includes('Magick++-config --cppflags', c_lib) #oof2setuputils.add_third_party_libs('Magick++-config --ldflags --libs', # c_lib) #RCL: oof2setuputils.add_third_party_libs('Magick++-config --ldflags',c_lib) magicklibs='Magick++ Wand Magick jbig lcms tiff freetype jasper jpeg png fpx Xext Xt SM ICE X11 bz2 xml2 z gdi32 pthread m pthread' for ml in string.split(magicklibs,' '): c_lib.externalLibs.append(ml) else: print "Can't find Magick++-config! Your ImageMagick installation may be defective." c_lib.externalLibs.append('oof2common') Note that I took the output of "Magick++config --libs" on my system (-lMagick++ -lWand -lMagick -ljbig -llcms -ltiff -lfreetype -ljasper -ljpeg -lpng -lfpx -ldpstk -ldps -lXext -lXt -lSM -lICE -lX11 -lbz2 -lxml2 -lz -lgdi32 -lpthread -lm -lpthread), removed -ldpstk and -ldps because cygwin can't find them, and put the modified output (after taking out the leading "-l") in the string magicklibs. Although cygdps-1.dll and cygdpstk-1.dll may be present, I do not have libdps.a and libdpstk.a on my system.
- Invoked the build/install command: prompt> python setup.py build --library-dirs=/bin --libraries=python2.4 --blas-libraries="blas lapack m" install --prefix=/HOME/RHON (The --blas-libraries option may not be necessary in newer versions of setup.py.)
- Set PATH and PYTHONPATH (command line or .bashrc) export PATH=/HOME/RHON/lib:/HOME/RHON/bin:.:$PATH export PYTHONPATH=/HOME/RHON/lib/python2.4/site-packages (Setting LD_LIBRARY_PATH did not work, so I put the path /HOME/RHON/lib into PATH.)
- To run oof2 in text mode: prompt> oof2 --text
- To run oof2 in graphics mode, start X and invoke: prompt> DISPLAY=:0.0 oof2 or enter "startx" at the prompt, then run oof2 on the X terminal.
Status (10/05/06) An error similar to the lock error mentioned below is documented here: http://www.cygwin.com/ml/cygwin/2005-07/msg01378.html The sample program from this site also returns an error on my cygwin system. An error also shows up when I run /usr/lib/python2.4/test/regrtest.py (10/04/06) Found a better solution to the pango/get_metrics problem on cygwin. Instead of "None", fontcontext.get_language() is passed as argument to get_metrics(). This seems to work just fine in sancho (as well as fixing the bug on cygwin). But if it gives problems on other platforms, I may check for sys.platform before making this change. One caveat: On sancho, font.get_metrics(None).get_approximate_char_width() gives a value of 9125, while font.get_metrics(fontcontext.get_language()).get_approximate_char_width() returns a value of 6505. The GUI looks just fine in either case. (10/04/06) Got oof2 to run in graphics mode:
The Pango-ERROR is still there, and it occurs in gtkutils.py on the line
that calls get_metrics(None).
As a temporary workaround to this bug, I put hard-coded values as such:
def widgetFontSizes(widget):
fontdesc = widget.get_style().font_desc
fontcontext = widget.create_pango_context()
font = fontcontext.load_font(fontdesc)
#RCL:
#fontmetrics = font.get_metrics(None)
#return (fontmetrics.get_approximate_char_width()/pango.SCALE,
# fontmetrics.get_approximate_digit_width()/pango.SCALE)
return (9000/pango.SCALE,
8000/pango.SCALE)
Another glaring bug shows up when one tries to view a microstructure by opening the
graphics window. An "error: can't allocate lock" occurs. On the terminal, it says
"sem_init: Resource temporarily unavailable." This bug does not show up when oof2
runs with --unthreaded.
