/* This file creates the getbuildinfo2.c file, by
|
|
invoking subwcrev.exe (if found).
|
|
If this isn't a subversion checkout, or subwcrev isn't
|
|
found, it copies ..\\Modules\\getbuildinfo.c instead.
|
|
|
|
A file, getbuildinfo2.h is then updated to define
|
|
SUBWCREV if it was a subversion checkout.
|
|
|
|
getbuildinfo2.c is part of the pythoncore project with
|
|
getbuildinfo2.h as a forced include. This helps
|
|
VisualStudio refrain from unnecessary compiles much of the
|
|
time.
|
|
|
|
Currently, subwcrev.exe is found from the registry entries
|
|
of TortoiseSVN.
|
|
|
|
make_buildinfo.exe is called as a pre-build step for pythoncore.
