[Fwd: g77 data segment]

[Fwd: g77 data segment]

[Toon Moene]

I got the following question, to which I don't know the answer.

Could an AIX guru reply to this (David ?) - that is, I assume that the
reference to `xlf' means that we're talking IBM here ...

Thanks in advance,

I have been reading the manual pages for GNU Fortran on the internet trying to
find an equivelent command for the -bmaxdata command from xlf Fortran. The
command from the xlf function states
'-bmaxdata:<bytes>
                  Specifies the maximum amount of space to reserve for the
                  program data segment, if you need more than 256Mb.'

I have not use g77 before and am looking for a similar command that will allow
up to 512Mb data segment. I would appreciate any help or advice you can give.

Thankyou

	-bmaxdata is an AIX linker commandline option.  AIX compilers pass
commandline options beginning with -b to the link phase.  GNU compilers
have another meaning for -b commandline options.

	One can pass any commandline argument directly to the linker using
the "-Wl," GNU compiler commandline option.  To set maxdata use
-Wl,-bmaxdata:NUMBER, e.g. -Wl,-bmaxdata:0x20000000 on the GNU Fortran
link line.
