Re: installing g95 under cygwin - similar problem

Regarding G95 on cygwin, I'm having a similar problem, but the message is
slightly different:
g95: installation problem, cannot exec 'as': No such file or directory

However, running g95 without input file correctly results in: "g95: no
input files" and
"g95 -E <file>" lists the input file, so I assume the symbolic link to the
executable is OK.

Any ideas?

Thanks

I smell a contradiction here.. ;-)

As 'as --version' itself says, 'as' is the assembler. The linker is a
separate program, called 'ld'.

I'm pretty sure that both are needed for a functioning g95
installation (unless you can use some builtin windows linker if such a
thing exists).

Thanks for the quick reply. I checked my present cygwin setup, and a lot
more than just 'as' and 'ld' is missing. Going thru the documentation now
and will do the necessary downloads and upgrades.

as and ld are part of the binutils package IIRC.
