This page is read only. You can view the source, but not change it. Ask your administrator if you think this is wrong.
Page contains my notes how to fix and patch packages from PLD repository. 

In building enviroment try to build package (it will be python-[[:PythonMagick|PythonMagick]] in my example). Below comamnd downloads current version of spec, sources patches) and starts to build: 

<file>[matkor@appserver3 ~/rpm/packages]$ ./builder -v  python-PythonMagick.spec
</file>
If it fails let's uncompress sources only by issuing -bp switch. 

<file>[matkor@appserver3 ~/rpm/packages]$ ./builder -v  -bp python-PythonMagick.spec
</file>
Now we can make backup of file we wish to edit 

<file>[matkor@appserver3 ~/rpm/BUILD/PythonMagick-0.9.1/m4]$ cp -p ax_python.m4 ax_python.m4.ac_python_fix
</file>
Pls use non present in source postifx ( in above exmple:.ac_python_fix) - we will use it to generate patch file later. 

Now we can test if our fixes helped if so, generate patch file to be included in spec file: 

<file>[matkor@appserver3 ~/rpm/BUILD/PythonMagick-0.9.1]$ gendiff . .ac_python_fix
[matkor@appserver3 ~/rpm/BUILD/PythonMagick-0.9.1]$ gendiff . .ac_python_fix  >../../packages/python-PythonMagick/python-PythonMagick-ac_python_fix.patch
</file>
Note we generate  patch from main dir of build dir, and we use package name as prefix for patch name (it helps include patch in spec and filter all patches) 

Add generated patch to spec file by adding: 

<file>Patch0:     %{name}-ac_python_fix.patch
</file>
and in %setup section of spec file: 

<file>%patch0 -p1
</file>
If now builds is satisfactory we should publish our fix to repository, by adding patch: 

<file>[matkor@appserver3 ~/rpm/packages/python-PythonMagick]$ cvs add python-PythonMagick-ac_python_fix.patch 
cvs server: scheduling file `python-PythonMagick-ac_python_fix.patch' for addition
cvs server: use 'cvs commit' to add this file permanently
</file>
Updating Release number, and comitting changes: 

<file>[matkor@appserver3 ~/rpm/packages/python-PythonMagick]$ cvs commit -m "- Release 2. Autoconf Python headers detection fix."  python-PythonMagick.spec  python-PythonMagick-ac_python_fix.patch
</file>
