HYSPLIT Forum: hysplitbbs.arl.noaa.gov

I'm trying to compile HYSPLIT from source to get around some issues we have with the pre-compiled version's use of relative directories.

However, I have run into an error when compiling when it starts building the dbf editor:

Building the dbf editor [Fri Mar 5 14:56:54 EST 2021]
ERROR: see '/.../opt/hysplit-5.0.0/hysplit.v5.0.0/make.2021-03-05.log' for details

When I review the log I find this:

==============================================================================
Building the dbf editor [Fri Mar 5 14:56:54 EST 2021]
------------------------------------------------------------------------------
...
gcc -I../include -o ../../../exec/txt2dbf txt2dbf.c -L./ -lDbf

make[1]: *** [txt2dbf] Error 1
make[1]: Leaving directory `/.../opt/hysplit-5.0.0/hysplit.v5.0.0/gisprog/dbf/source'

=============================================================================

I've tried this into the Makefile & Makefile.inc to set a CFLAG for -std=c99 but it doesn't seem to work;

CFLAGS+=" -std=c99"

Has anyone run into something similar to this and been able to solve it?

Thank you!

Best,

Michael

The compilation error was fixed in June 2020. Please use the latest release of the source code.

Thanks Sonny,

I see, I was using 5.0.0 but will try with 5.0.2 Thank you!

Best,
