Hi,
cmake works nice so far :-) Thanks guys!
Recently my MSVC builds have been quite slow, so I decided to move the
PDB files to a ramdisk. (This really speeds things up, I'm using a
quad-core CPU so mspdbsrv.exe gets in the way quite often.)
I found out that setting the PDB pathname in CMake is not possible. I
would like to specify something like
ProgramDataBaseFileName="R:\$(TargetName)-$(ConfigurationName)"
(MSVC appends ".pdb" or ".idb" as necessary). However, contrary to what
I've seen on the wiki, setting TARGET_PDB (using SET or
SET_TARGET_PROPERTIES) does nothing.
So I checked the source code, and the generator
(cmLocalVisualStudio7Generator.cxx) does this (at about 3 places):
fout << "\t\t\t\tProgramDataBaseFileName=\""
<< target.GetDirectory(configName) << "/"
<< target.GetPDBName(configName) << "\"\n";
This suggests that even if I managed to change PDB name somehow, I could
not change the directory.
So I ended up compiling my own cmake.exe with the above changed to my
hard-coded path, but I would really like to see this configurable.
By the way, I can't see why you bother retrieving all pathnames in the
generator. Hardcoding something like
fout <<
"\t\t\t\tProgramDataBaseFileName=\"$(TargetDir)$(TargetName)"\n";
would have exactly the same effect. IMHO this would also be easier to
modify so that the users can choose their own preferred PDB location.
Is there some other way of achieving what I need (apart from
re-compiling cmake and/or waiting for new options)?
Thanks,
Filip
