[Met_help] [rt.rap.ucar.edu #43124] History for Can not find -lm

[RAL HelpDesk {for Paul Oldenburg}]

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

Hello,
I am trying to compile MET using intel compilers. It stopped at pcp_combine with following message:

ld: cannot find -lm
make[3]: *** [pcp_combine] Error 1
make[2]: *** [all] Error 2
make[1]: *** [targets] Error 2
make: *** [all] Error 2

I thought -lm is directive to using libm, was that correct?

Could you pls give me hints to resolve this? Thanks

Mahally

Mahally,

Can you please send us a copy of your Makefile and make log?  It
appears that your compiler cannot find the system
library libm.a, which is a math library.  A couple common causes for
this error are using a c compiler instead of a c++
compiler or an incorrectly configured c++ compiler.  Please verify
that you are using a c++ compiler and that it is
configured correctly and has access to the system libraries.

Also, you may find the compilation section of the online tutorial
helpful:

Please let me know if you have any questions.

Thanks,

Paul

Thank you very much, it has been resolved now, after changing the
compiler from gcc to g++.

Regards,

Mahally
