Randy,

Here's a MET-Help follow-up email that was sent directly to me.  Could you
please respond to this user.

The history is that this user tried to get METv1.1 to compile on "lenny". 
But she ran into a bunch of problems.  So I sent here a set of patches I
thought would fix the problem.  The patches did fix several errors, but
she was still seeing some on "lenny".  So she tried using the PGI
compilers (on etch I think), and got METv1.1 to compile fine.

Now she's going back and trying to work on building METv1.1 on "lenny"
again.  She'd like instructions for how to fix the code herself. 
Basically, when she encounters a compilation error, she wants to know how
to figure out which include files she'll need to add.

Thanks Randy,
John

Hi, John,

Since MET just can not be compiled properly on my "lenny" debian, would
you mind giving me some advice so that I can fix all these error myself?
Thank you very much!

great help! After patching MET the previous there are no previous
errors now. However, serveral 'exit() not declared' errors come. I
tried to include some header files(cstdlib) in those source code. And
the errors have gone. It seemed that many of the MET programs try to
call some system standard function without including appropriate header
file(e.g.cstdlib). If it is built with gcc, the compiler will complain.
But I also found that a PGI compiler could compile it without errors.

No "isdigit() not declared" error again. This was quite strange. The
Makefile and the log file are in the attachment. I am running a
Debian (Lenny) operating system. And my g++ version information are:
