Thread: compiling a program that uses the SAC I/O library

sac-config is supposed to be a shortcut to those library flags. You
should be able to run sac-config stand-alone on the command line and
see if it outputs the -L and -l flags properly.

That worked. So, was I using sac-config unnecessarily?

You want something like (without sac-config)

*gfortran -o rdsetupsimul rdsetupsimul.1.brfix.f
-L/usr2/OS-DEPENDENT/Linux_Generic_unknown/sac-101.6a/lib -lsacio*

-Lpath/to/lib
-lsacio (the library)

Thanks Brian,

It's been ages since I've tried to compile code, so I may be
doing something clueless here, but it seems that sac-config is
choking. Based on (my misunderstanding of?) your advice, I've
tried:

*gfortran -o rdsetupsimul rdsetupsimul.1.brfix.f `sac-config -c
-l sacio
-L/usr2/OS-DEPENDENT/Linux_Generic_unknown/sac-101.6a/lib -lsacio `*

and

gfortran -o rdsetupsimul rdsetupsimul.1.brfix.f `sac-config
--cflags --libs sacio
-L/usr2/OS-DEPENDENT/Linux_Generic_unknown/sac-101.6a/lib -lsacio `

In both cases,

I get output that suggests to me that the me that sac-config is
not happy with the input, because it is telling me the proper usage.

Usage: sac-config [-clvp] [--prefix[=DIR]] [--version] [--libs]
[--cflags] libs

It seems gfortran is trying to compile, and isn't, as I don't
see any compiled file output.

Best,

Derek

Derek,

Try added sacio to the sac-config command

% sac-config --libs sacio
-L/usr/local/sac/lib -lsacio

You only have the path and are missing the library.

Hi,

I'm trying unsuccessfully to compile a fortran program using
the SAC provided i/o libraries, but I am getting an error
message that is confusing me. I'm using sac 101.6a, and the
libraries I need are at
/usr2/OS-DEPENDENT/Linux_Generic_unknown/sac-101.6a/lib.

*% gfortran -o rdsetupsimul rdsetupsimul.1.brfix.f
`/usr2/OS-DEPENDENT/Linux_Generic_unknown/sac-101.6a/bin/sac-config

sacio" `*

I guess I don't understand why it is wanting regarding
/usr/local/sac/include if I am giving it the prefix input.

Note that this gives me what I expect:

*% sac-config --libs
--prefix="/usr2/OS-DEPENDENT/Linux_Generic_unknown/sac-101.6a/lib"
*

namely, what I input:

-L/usr2/OS-DEPENDENT/Linux_Generic_unknown/sac-101.6a/lib

and I have confirmed this it the correct path to the libraries.


Thanks,

Derek
