Make File Conditiona Compilation in HP UNIX

CA1490051 — Fri, 14 Mar 2008 06:59:44 GMT

Hi All,

I am trying to put a if condition in a Makefile.
The Makefile is as follows
HOSTNAME = `uname`
HP = HP-UX

all:TARGET
ifeq ($(HOSTNAME),$(HP))
echo $(HOSTNAME)
else
echo "NOT HP"
endif

If i try to make I get the following error message

Make: Must be a separator on rules line 7. Stop.

Can Someone correct me where i am going wrong.

thanks and regards
Vikram

You aren't using gmake:

Hi,

even with gmake, the character before your 'echo's must be a TAB, no spaces, because that's part of a makerule.
The result of 'make' after this correction will be the output
Don't know how to make 'TARGET'
when the above lines are your complete Makefile.

Hi All,

There was an error in my copy paste

The Makefile looks as below

HOSTNAME = `uname`
HP = HP-UX

all:TARGET
TARGET :
ifeq ($(HOSTNAME),$(HP))
echo $(HOSTNAME)
#uname
else
endif

and there is a tab fo rthe echo statement not spaces.

I am not using gmake i am using make. IS this not possible to achieve this through make.

thanks and regards
Vikram

Why not? What were you using (where) when
you created this "make" file? (For that
matter, it's just possible that knowing which
HP-UX you're using (hardware, version) might
be interesting, too.)

If "man make" doesn't mention conditionals
like "ifeq", then I'd assume that this "make"
program doesn't support them.

Depending on exactly what you wish to do
conditionally, it may be possible (if not
convenient) to devise more complex rules
which do (a lot of) "uname -s" testing to
decide what to do differently on different
host systems. If you need more complex
OS-dependency in the "make" file structure,
then you may need to use a "make" program
which allows it.

That's what I said. HP-UX's make doesn't support this.

Not in this case with make. :-(

Right but simpler to use a real make.
