[Met_help] Re: MET V1.0 compilation in MAC

[John Halley Gotway]

Jagan,

Glad to hear that you were able to get it to work... other than PB2NC.

Regarding your comments... yes, they are all correct:

MET may use either the F2C or G2C library.  If G2C is already available on your machine, go ahead and use that.  If not, you could download the F2C source code and build it locally.  When you do, set 
the F2C_LIBS to the directory containing the file libf2c.a or libg2c.a.  I don't believe that F2C_INCS is actually being referenced in the source code, but go ahead and set it to the directory 
containing f2c.h or g2c.h.  Then, set F2C_LIBNAME to either -lf2c or -lg2c to indicate which library you're using.

Regarding (3), this issue is listed on the "known problems" page on the MET website: http://www.dtcenter.org/met/users/support/known_issues/METv1.0/METv1.0_known_issues.php
As a rule, we have not been updating the tarball with the latest bug fixes.  However, future releases will contain all of the fixes.

Regarding the errors you're getting compiling PB2NC, I'd like to refer you to Lacey Holland, who's also working on MET (and who I've copied on this email).  She has been able to build METv1.0 on her 
Mac and may be able to provide you some advice.  It seems problematic to me that you're not able to compile using the "-static" option.  Instead, you're compiling using "-dynamic".  Lacey, were you 
able to compile on your Mac using "-static" or did the compiler complain about that?  In the error messages from the linker, it looks like there's conflicts between the libgcc_s.10.4.dylib and 
libg2c.0.dylib libraries.

Lacey, did you build MET on your Mac using G2C or F2C?  Jagan, you could try downloading and installing F2C (follow the F2C link from the MET downloads page at 
http://www.dtcenter.org/met/users/downloads/index.php) locally to see if that would help.  Perhaps, you could bypass these library conflicts that way.

Thanks,
John
