RE: Using environmnet variables in make

[John Calcote]

Alan,

Try adding a backslash after the export QA... statement like this:

test:
   export QA_STEP=start; \
   touch ${QA_STEP};

make executes each line in a separate shell, so QA_STEP will not be set in
the shell that executes the touch statement unless you execute both commands
in the same statement.

Subject: Using environmnet variables in make


Hi,
   I have the following Makefile

.EXPORT_ALL_VARIABLES:
.SUFFIXES:

test:
   export QA_STEP=start ;
   touch ${QA_STEP};

Which I run using "gmake". This gives me:

slappy628: gmake test
export QA_STEP=qa_rtl ;
touch  ;
touch: file arguments missing
Try `touch --help' for more information.
gmake: *** [test] Error 1

Can anyone tell me what I am doing wrong? No matter what I try I can not get
it to pick up on the environment variable set. Help would be much
appreciated.
Thanks
       Alan
