  Initial Request
----------------------------------------------------------------

Good day,

I trust this e-mail finds you well.
I have been trying to install METv4.1 but I keep on getting the same error which I am struggling to fix, which I hope you will be able to assist with.
I have attached to this e-mail my log file from the make process as well as my user defined file.

I have installed netcdf v3.6.3, g2clib-1.4.0 as well as gfs-1.15.

Any assistance in solving this problem will be greatly appreciated.

Kind regards,
Stephanie

Stephanie,

Thank you for sending the make log.  I took a look and see that the
linker can't find the standard math library:
     /usr/bin/ld: cannot find -lm

Since, by default, MET is doing static linking, the linker is looking
for a library archive file name "libm.a", but can't find it.  The
linker
being unable to find the standard math library is a bad sign and often
means that the compiler is not installed/configured well.  We could
locate the correct library archive file and tell the linker where to
find it, but often, if the linker can't find the math library,  you'll
often have a whole host of other compilation issues arise.

Here are some things you could consider:

   (1) If you can locate "libm.a" on your system, you could tell the
linker where to find it by editing the top-level METv4.1/user_defs.mk
file.  Just add "-L/my/directory" to the "CXX_LIBS" line, where
/my/directory is the directory containing the file libm.a.  But as I
mentioned above, you may run into other problems after resolving this
one.

   (2) You could try rebuilding MET using dynamic linking rather than
static linking.  Perhaps that would work better:
     - Just edit the top-level METv4.1/user_defs.mk file and remove "-
static" from the CXX_FLAGS and FC_FLAGS lines.
     - Then rebuild MET, being sure to execute a "make clean" first.

(3) If you have other compilers (PGI, Intel) available on your system,
you could try rebuilding MET and all it's dependent libraries using
them.

   (4) You could talk to a systems administrator about the problems
you're having, and reinstall the compilers.

Sorry I don't have an easy answer for you.  Please let me know how it
goes.

Thanks,
Julie Prestopnik

Hi Stephanie.  I just wanted to follow up and see if you had any luck
