I recently converted from PVCS to GNU make
and I am having a problem with incremental builds.
I am running gmake 3.80 on Windows XP
Professional, using cl.exe and link.exe from MS Dev Studio 6.0. This is a
C application. I have about 6 C file1 I am compiling.
The problem is after I successfully build
the DLL, I go in and change one C file. When I go to make the DLL again,
it compiles all of the C files again. I want it to just recompile the one
file and link. I tried using the –t option when I call make, but then the
file I need to get compiled is not compiled.
Here is my make file layout.
SHELL = /bin/sh
MODULE = file6
SOURCE = $(pwd)
