Summary: symbol conflict for 'readahead'
Initial Comment:
I'm encountering the error below with python 2.5 on current Debian x86.
src/python-2.5.1c1/Objects/fileobject.c:1845: error: conflicting types for
'readahead'
/usr/include/bits/fcntl.h:187: error: previous declaration of 'readahead' was
here
It may be that's it's provoked only by my slightly custom embedded build
process - perhaps the standard build does not include fcntl.h while compiling
this file.
A fix is trivial - just to rename the static readahead function to something
else, e.g. as below.
