When we’re checking out SDL-2.0 from HG it would be nice if we could not have this error about generated header files.

Code:  
configure: error:  
\*\*\* When building from Mercurial you should configure and build in a  
separate directory so you don’t clobber SDL\_config.h, SDL\_revision.h

Generated files generally should not be checked into the VCS.

Right now I have to hack the configure to allow the build.

Read the message carefully, afterwards create e.g. a directory named  
build, change into it and call configure from there

~/devel/SDL# mkdir build  
~/devel/SDL# cd build  
~/devel/SDL/build# …/configure  
…

and life is good again :-).

Well, it’s just tolerable. 🙂

Now good, that would be not needing to do this.
