Description Michal Suchanek 2010-04-19 07:40:09 UTC

to reproduce

1) checkout the 2.4.19 version of drm from git
2) run ./configure
3) update to 2.4.20
4) mkdir build ; cd build ; ../configure ; make

the build in the build directory includes the old config.h from the source directory and fails.

What you're doing is not supported.  I get

  configure: error: source directory already configured; run "make distclean" there first

when I try to configure in a build-dir with an already configured source dir.  Doing make distclean removes the config.h in the source dir.
