COMPLETE list of gfortran command line options?

[GerritGroot]

Hi,

Does anyone know where I can find a COMPLETE list of the gfortran command line (flag) options?

At

http://gcc.gnu.org/onlinedocs/

I can't find "-shared" for example.

Is there a COMPLETE list of these flag options with explanations somewhere available?

Thanks,

Gerrit

I've found a good deal, if not all, of the options (including -shared) at

http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc.pdf

See p. 143 as printed on the PDF for the -shared option.

Hope that helps!

For gfortran flags, type

gfortran --help

For linking/library flags, type

ld --help

-shared is passed to ld to create shared library. Most of the stuff that gfortran doesn't understand, it passes to ld.

Thanks, xwb. That's a useful trick to know!

Thanks both!!

I understand that ld is a separate executable that comes with gfortran, right?

Eehm, what's it used for?

(Sorry for my ignorance )

gfortran is the compiler, ar and ld are the linkers (or linkage editors or consolidators depending on which operating system you're used to). ar and ld can also be used to make libraries.

If you wish to check dependencies, use ldd on your executable.
