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
--cflags --libs
--prefix="/usr2/OS-DEPENDENT/Linux_Generic_unknown/sac-101.6a/lib sacio" `*

f951: Warning: Nonexistent include directory ‘/usr/local/sac/include’
[-Wmissing-include-dirs]
/tmp/ccLy95iX.o: In function `MAIN__':
rdsetupsimul.1.brfix.f:(.text+0x1218): undefined reference to `rsac1_'
rdsetupsimul.1.brfix.f:(.text+0x1265): undefined reference to `getfhv_'
rdsetupsimul.1.brfix.f:(.text+0x12ae): undefined reference to `getfhv_'
rdsetupsimul.1.brfix.f:(.text+0x12f7): undefined reference to `getfhv_'
rdsetupsimul.1.brfix.f:(.text+0x1340): undefined reference to `getfhv_'
rdsetupsimul.1.brfix.f:(.text+0x1389): undefined reference to `getfhv_'

/tmp/ccLy95iX.o: In function `MAIN__':
rdsetupsimul.1.brfix.f:(.text+0x13fd): undefined reference to `getkhv_'
collect2: error: ld returned 1 exit status

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



  • 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.

    • 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]

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

        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)

          • 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.

            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]

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

            I guess I don't understand why it is wanting regarding

            Note that this gives me what I expect:

            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 Rob, got it figured out with this advice.

              For completeness to the thread (in case it is useful for anyone), here's
              a version that seems to work with sac-config. It also outputs a -I
              flag to the location of the $SACHOME/include directory, but I don't need
              that for this code.

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

              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?
