Summary: .vcproj .LIB target gets always rebuilt
Initial Comment:
ANy .vcproj that generates a .LIB file reruns the [lib]
task every single time you execute nant - i.e., no
dependency checking between the final target and the
intermediate .OBJ files
Obviously, this causes pain and suffering if lots of
other projects depend on the .LIB file.
(Last tested with 2005-04-20 nightly)

This is now fixed in cvs.
Thanks for the "patch".

Since I'm an impatient person :), here's a proposed fix:
(Sorry, don't have patch/diff running, so it's a bit manual)
In LibTask.ExecuteTask, add the following lines after
setting up the BaseDirs:
if (!NeedsRebuilding()) {
return;
}
Also, add the following function to LibTask:
#region Protected Instance Methods
/// <summary>
/// Determines if the output needs to be rebuilt.
/// </summary>
protected virtual bool NeedsRebuilding()
{
if (OutputFile != null)
{
// check if output file exists - if not, rebuild
if (!OutputFile.Exists)
{
Log(Level.Verbose, "Output file '{0}'
does not exist,
rebuilding library.",
OutputFile.FullName);
return true;
}
// check if .OBJ files were updated
string fileName =
FileSet.FindMoreRecentLastWriteTime(Sources.FileNames,
OutputFile.LastWriteTime);
if (fileName != null)
{
Log(Level.Verbose, "'{0}' has been
updated,
relinking.", fileName);
return true;
}
}
return false;
}
#endregion Protected Instance Methods
... That does the trick at least locally. I'd appreciate a
quick ping when/if the fix is landed. Thanks!
