You can add source files to a
project manually using the menu item Project/Add to
Project/Files, but this is tedious. Welcome to the fun world of VC++!
I tried adding the header file in question to the Headers list,
modifying it, and rebuilding, and it still didn’t rebuild. I just checked – I added
DynamicArrays.h to the Headers folder of my DynamicArray/DynamicArrayTest5
project. Built the test, made a modification to DynamicArrays.h, and hit
rebuild. Nothing happened. I think this is actually a problem with templates. I’ve become a heavy
user of VC++ over the past 8 months (with Microsoft’s compiler) and I’ve occasionally
seen a dependency screw-up, but mostly it works correctly. It appears to do a
proper dependency analysis. For instance, have a Proximation test code (which
uses not complicated templates, though there are some traits classes and
template functions here and there) with the following projects: CSum CSumProxy CsumStub ProxLib TestCreateInstance These are all in the same workspace and TestCreateInstance depends on
the first four projects. Furthermore, the first three projects have files that
depend on a header file ISum.h, as does the main program in TestCreateInstance.
ProxLib does not depend on this file. If I modify ISum.h and hit the rebuild
button, it rebuilds CSum.dll, CSumProxy.dll, CSumStub.dll, and finally the
TestCreateInstance object and executable (but not anything in ProxLib). This
happens in spite of the fact that ISum.h is not in any of the “Headers” folders
in these various projects. There is a folder that is automatically created by
Visual Studio called “External Dependencies” and ISum.h shows up there. VC++ does this correctly with and without the VTune C++ compiler
selected. Unfortunately, I can’t test Pooma with VC++ sans VTune, so I don’t
know if the dependency analysis breaks because of something Pooma is doing
(like file-naming conventions?), something VTune is doing, or if it is just a
bug in VC++ when using templates. Hmmm. Indeed, there is NO External
Dependencies folder in the DynamicArrayTest5 project, which indicates that, for
whatever reason, it is completely blowing its dependency analysis. I’m guessing
that the templates are confusing it. All I know is that it is a major pain in
the butt. Jim |
