bracket problem when migrating scripts from Solaris to Linux

[jon_at_Lforum]

Hello, there:

I am on a project to migrate some make files from Solaris box (SunOS 5.8 Generic_Virtual sun4v sparc SUNW,T5440) to Linux (Linux 2.6.9-89.0.16.ELsmp #1 SMP Tue Oct 27 03:51:52 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux)

It came to my attention that the make files refer to environment variables in such a way as, for instance, $(JAVAC), using a round bracket. This is where the problem occurs when running it on Linux. Bear in mind this is the env variables, not some variables defined inside the scripts.


I did a test myself, from both boxes I "export TEST=test....", and I tried "echo $TEST", "echo ${TEST}" and "echo $(TEST)". The result: the first two worked on both platforms while the last worked on neither of them (the error message: ksh: TEST: not found).

Both platform are in a ksh session.

I was confused that how come the embeded $(JAVAC) can work on Solaris without complaint?

This is my first time to post a thread in this forum, thanks!

Even if it is an environment variable, it needs
to be stated in the makefile. I don't think make
magically knows variable outside of what's in the makefile.

you are right, my bad. Thanks!
