I am using the hpux ported/pre-compiled gmake, version 3.77
under HPUX 11.00, and I am running into some unexpected
behaviour. Any help would be appreciated.
I have a Pattern rule defined, and within that pattern rule, I need
to check for the existance of another file, and slightly change
the "build" step to include the file if it exists. I have included
my makefile below.
To use this, first do a 'make initial'. This will create (touch) all
the required files. Then, each successive invocation of
make will touch the proper files to re-run the tests. This
is only a demo Makefile, but it demonstrates the problem I
am experienceing.
The area I am concerned about is in the middle of the
output where it says:
findicf = ""
making with icf file ""
making with icf file ""
Both of these lines should say:
making WITHOUT icf file ""
making WITHOUT icf file""
If anyone has any clues, or insights, I would appreciate them
Thanks.
