Install MySQL-python on Cygwin

After pulling my hairs and scavenging the Google, finally I succeeded installed the MySQL-python on Cygwin.
  • Build MySQL on Cygwin
  • Download MySQL source package from here. I was using mysql-5.0.76.tar.gz
  • configure && make && make install
  • Install MySQL-python on Cygwin
  • Download MySQL-python . I was using 1.2.2. Unzip it.
  • ./setup.py install, if you run into any problem, please have look on the readme file of the MySQL-python package. You may need to update threadSafe=False in the site.cfg file.

PIL error: IOError: decoder jpeg not available

After installing PIL on Cygwin, I ran into the following error while I am trying to load data from a JPEG file.
IOError: decoder jpeg not available
To solve this problem I did the following steps:
Remove the installed PIL from Cygwin:
rm -rf /usr/lib/python2.5/site-packages/PIL
rm /usr/lib/python2.5/site-packages/PIL.pth

Install libjpeg by using Cygwin setup.exe

Rerun PIL setup.py install.

unable to remap C:\cygwin\bin\tk84.dll

While installing PIL(Python Imaging Libary) on Cygwin, I ran into the following error:
5 [main] python 4388 C:\cygwin\bin\python.exe: *** fatal error - unable to remap C:\cygwin\bin\tk84.dll to same address as parent(0x410000) != 0
x700000
22 [main] python 4636 fork: child 4388 - died waiting for dll loading, errno 11
error: Resource temporarily unavailable

Fortunately, with the help of Google, it is easy to find an existing solution from Datahammer's blog:
c:\cygwin\bin\ash
cd /bin
./rebase -b 0x100000000 tk84.dll

Rerun the PIL setup.py install in Cygwin shell.

Update: If you run into remap error on Cygwin, you could try rebaseall
c:\cygwin\bin\ash
cd /bin
./rebaseall
