undefined errors while compiling fortran code

[vineetpant]

Hello ,
I am trying to cross compile simple "hello world" printing fortran code with the following command -

o64-g++ test.f -O3 -o test

and i am getting following errors, i think there should be some library which is missing from being referenced.

---

"gfortran_set_args", referenced from:
_main in ccunQ19M.o
"__gfortran_set_options", referenced from:
_main in ccunQ19M.o
"__gfortran_st_write", referenced from:
_MAIN in ccunQ19M.o
"gfortran_st_write_done", referenced from:
_MAIN in ccunQ19M.o
"gfortran_transfer_character_write", referenced from:
_MAIN in ccunQ19M.o
ld: symbol(s) not found for architecture x86_64

Thanks & Regards,
Vineet Pant

You need to use x86_64-apple-darwin14-gfortran, not o64-g++ or x86_64-apple-darwin14-g++.

$ cat test.f
Program Hello
  Print *, "Hello World!"
End Program Hello

The dynamic way:

$ x86_64-apple-darwin14-gfortran -ffree-form test.f -o test

$ x86_64-apple-darwin14-otool -L test
test:
        /data/development/osxcross/target/bin/../x86_64-apple-darwin14/lib/libgfortran.3.dylib (compatibility version 4.0.0, current version 4.0.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)
        /data/development/osxcross/target/bin/../x86_64-apple-darwin14/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
        /data/development/osxcross/target/bin/../x86_64-apple-darwin14/lib/libquadmath.0.dylib (compatibility version 1.0.0, current version 1.0.0)

$ dyld test
 Hello World!

The static way:

$ x86_64-apple-darwin14-gfortran -static-libgcc -static-libgfortran -ffree-form test.f -o test

Still links quadmath dynamically:

$ x86_64-apple-darwin14-otool -L test
test:
        /data/development/osxcross/target/bin/../x86_64-apple-darwin14/lib/libquadmath.0.dylib (compatibility version 1.0.0, current version 1.0.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

If you want to link quadmath static too, run (in osxcross/target):

$ cp -r x86_64-apple-darwin14 backup
$ find x86_64-apple-darwin14 -name "libquadmath*dylib" -exec rm {} \;

Use the same flags again:

$ x86_64-apple-darwin14-gfortran -static-libgcc -static-libgfortran -ffree-form test.f -o test
$ x86_64-apple-darwin14-otool -L test
test:
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

Hi ,
It is working fine , i built it with statically.

Thank you
