I was building my project, madman [1], on a new machine where no C++ was installed. Instead of an error message, I got opaque errors from the configure stage of the build. From the config.log (attached) it looks like scons tried to run an "empty command", passing just the options, see this snippet from config.log:

scons: `.sconf_temp/conftest_0.cpp' is up to date.
-I/usr/share/qt3/include -c -o .sconf_temp/conftest_0.o .sconf_temp/conftest_0.cpp
sh: -/: invalid option
Usage:  sh [GNU long option] [option] ...
        sh [GNU long option] [option] script-file ...

To make it a bit clearer: What I expected to happen was for there to be an error like: "No C++ compiler installed" instead of just keeping going with the build.

http://scons.org/wiki/BetterErrorMessages is a description of how this situation should be handled. At the time this comment is posted, it's an early draft, and comments and questions from those who have encountered the situation would be appreciated.

Bug party triage. Inherit the milestone and priority of a later dup.

Adjust triage of issues.

Bug party triage. Accumulate issues with this underlying problem as dups of a
common base issue.
