Hi there everyone,
This probably should go to comp.unix but anyway.
Question: How do you use the C-shell in a Makefile
'make' will pass this to the shell 1 (one) line at a time
and it will therefore give an error.
If you use the continuation on the end of the line, 'make'
will pass the line to the shelll, but the foreach statement
is all on one line and will therefore not work either.
Example:
------------------------------ Makefile ------------------------------
test:
foreach i (1 2)
echo "===== $i ====="
end
----------------------------------------------------------------------
We need to get the preceding Makefile working so as we can do more complex
things.
I have tried '\', '\n\' and all sorts of things on the end of the line
but no luck yet.
Any help would be gratefully accepted.
Taa, PeterK

make takes each action line as a separate shell exec. The way around that is to use a backslash (\) to escape each newline. Then make will run the entire bunch of lines as one line. To change the default shell command, equate SHELL=/bin/csh in the makefile. You might want to look at pmake, which is much better at this than make. Do a "man pmake" for more details. +-----------------------------------------------------------------------------+ | karron@nyu.edu Dan Karron | | . . . . . . . . . . . . . .

The problem is that 'csh' relies on the fact that all the constructs are on separate lines. eg: foreach i (*) echo $i end This will not work in a Makefile, even with '\' at the end of the line. -- Peter Kerney.
