makefile help

[sandeep t]

I have a Makefile as below:
-----------------------
all: ICU_BUILT

ICU_BULIT:
mkdir ......
cp ......
.
.
.
------------------------

I want to add two new targets(which r in other makefile) just before the ICU_BUILT target. I wan to call those targets with a variable with the same name as target.

all: ICU_BUILT drv_end

ICU_BUILT: MODULE=ICU_BUILT
ICU_BUILT: drv_begin
mkdir ....
cp.....

The problem is the MODULE name is local to target ICU_BUILT and not not known to drv_end target. How do I export this variable??

[sandeep t]

Is there any alternative to target-specific variable here?
I want to know is there ant way that I call a target once the commands get over?

all: target1
command..1
command .. 2

Where do I call target2 if I want to call it once the above commands are over?

There is no reply to this thread. Have I asked a wrong question?

Hi.

Have I asked a wrong question?

I think we don't understand what you are looking for.

I am not sure what you mean when you say "call a target". The problem may be with our differences in language.

Try to explain it in a different way, and, if possible, show us how you would like it to work, regardless of whether it does work or not.

If you supply code or a makefile, please make it a code block -- select the text, and click the # symbol above the text entry box to produce:

this is code line one
a makefile line:
program: dep1 dep1
  command1
  command2
  ...

This makes it easier to read ... cheers, drl

Thanks drl.. I'll try to explain here:

I have a Makefile:

target2:
         @echo target2
target1:
         @echo target1
all: target1 target2
         @echo commands

The output of the above makfile when run will be:

target1
target2
commands

How do I modify the makefile,without using additional targets, if I expect the following output:

target1
commands
target2

thanks !

Hi, sandeep t.

OK, consider this:

#!/bin/sh

# @(#) s1       Demonstrate make.

set -o nounset
echo
echo "GNU bash $BASH_VERSION" >&2
make --version | head -1 >&2
echo

echo " Change:"
cat <<EOF
target2:
        @echo target2
target1:
        @echo target1
all: target1 target2
        @echo commands
EOF

cat >makefile <<EOF
all: target1 ghost target2

target1:
        @echo target1

target2:
        @echo target2

ghost:
        @echo commands

EOF

echo
echo " To:"
cat makefile

echo
echo " Producing:"
echo

make

exit 0

which results in this output:

% ./s1

GNU bash 2.05b.0(1)-release
GNU Make 3.80

 Change:
target2:
        @echo target2
target1:
        @echo target1
all: target1 target2
        @echo commands

 To:
all: target1 ghost target2

target1:
        @echo target1

target2:
        @echo target2

ghost:
        @echo commands


 Producing:

target1
commands
target2

cheers, drl

Thanks drl.. But as I said.. I don;t want to add any extra targets.
See, basically we have working Makefiles and our product build also goes fine. Now, we want to report that build to our QAServer where we can see build results. So we have a Makefile(qa.mk) where we have all reporting commands in the form of targets. Its just we have to call the start targets(qa_start) before the actual component targets(icu_all) is called and call the end targets(qa_end) after it.

Current working Makefile

-------------------------------
all: ICU_ALL ICU_INSTALL

ICU_ALL:
           make -C .....
ICU_INSTALL:
           mkdir ......
           cp ......
-------------------------------

We want to have something like following on server:

ICU_ALL  PASS
ICU_INSTALL  FAIL

This will be our qa.mk where our reporting commands are defined:

----------------------------------
qa_start:
          qastart -id=COMPONENT .....
qa_end:
          qaend -id=COMPONENT ....
-----------------------------------

So I plan to modify the Makefile as follows:

-------------------------------------------------
include qa.mk
all: ICU_ALL ICU_INSTALL

ICU_ALL: QA_TARGET=ICU_ALL
ICU_ALL: qa_start
           make -C .....
ICU_INSTALL: QA_TARGET=ICU_INSTALL
ICU_INSTALL: qa_start
           mkdir ......
           cp ......
-------------------------------------------------

Here I plan to use target-specific variable to define my component name.
But the problem is where to call target qa_end in the above Makefile?

Thanks in Advance !!

Sorry.. In the above example.. please replace the "COMPONENT" in qa.mk with "QA_TARGET"
