Another bit on this subject; spent a good bit of time poking at the
.dsp files.
Seems to make sense to have both the "Output_Dir" and "Intermediate_Dir"
settings in *.dsp to be modified similarly.
I'd recommend for Debug builds:
# PROP BASE Output_Dir "Debug\$(ProjectName)_"
# PROP BASE Intermediate_Dir "Debug\$(ProjectName)_"
..and for Release builds:
# PROP BASE Output_Dir "Release\$(ProjectName)_"
# PROP BASE Intermediate_Dir "Release\$(ProjectName)_"
This way both builds behave similarly; all junk for each project ends up
in either "Release\<PROJECTDIR>_" or "Debug\<ProjectDir>_".
(Currently, Debug and Release builds behave differently)
So blowing away those two dirs will always remove project detritus.
Microsoft documents these two build settings:
* * *
Output Directory
Specifies the directory where tools such as the linker will place all
final output files that are created during the build process. Typically,
this includes the output of tools such as the linker, librarian, or BSCMake.
Intermediate Directory
Specifies the directory where tools such as the compiler will place
all intermediate files created during the build process. Typically,
this includes the output of tools such as the C/C++ compiler, MIDL,
and the resource compiler.
* * *
These sound like more or less like the same thing;
where all the build crap goes.
I've set all my dsp files similarly with the above, and builds OK
in parallel mode under VS2008. I'd think VS7 can digest this as well,
I'll check.
With these changes, it makes more use of disk space during builds
because the common files don't get overwritten. But that's bad for
parallel builds, and would seem to go against MS's design intentions,
which seem to want to keep these files separate.
Here's the diff for e.g. "keyboard.dsp" with those changes applied,
followed by the modified 'fixem' perl script that implements the
changes to both settings.
