Hi,
I'm trying to build a cross-compiler which should be running on a Fedora 32
system building objects for a IA64-OpenVMS system. I'm running the
compilation on a "up-to-date" Fedora 32 system.
It does not matter which version of gcc I try, I always get the same error
message (see below). For gcc-10.1.0 II used the configure command showed
below. immediately after that I did run "make" and after some time I got the
error liste below.
What do I do wrong?
./configure --prefix=/home/joukj/openvms --exec-prefix=/home/joukj/openvms --build=x86_64-unknown-linux-gnu --host=x86_64-unknown-linux-gnu --target=ia64-hp-openvms

Don't run configure in the source tree, see

This means you don't have an assembler for the cross target.

I would guess this coming somehow from configuring in the source
directory. The 'genmodes'
executable is produced for the BUILD system so the 'as' required here
would be the native one.
The './as' script is somehow broken.
What seems also to be missing is the prerequisite :
"In order to build GCC, the C standard library and headers must be
present for all target variants
for which target libraries will be built (and not only the variant of
the host C++ compiler)."
https://gcc.gnu.org/install/prerequisites.html
When there is no "--with-sysroot=<something>" to point to the required
'ia64-hp-openvms'
target libraries and headers (the assumption nowadays being a separate
$sysroot for the target
stuff), this mistake seems obvious. The "prerequisites" talks about
producing a native GCC but
just the same prerequisite is true for a cross GCC. People may have
installed only the 64-bit libs
and headers but the GCC build tries to build also 32-bit stuff and needs
32-bit libs and headers
in this task.
The same "--with-sysroot=<something>" is required in the binutils
configure to tell the target
linker where the target libraries are.

And the way it's broken is that one of the variables like
ORIGINAL_AS_FOR_TARGET is empty, meaning that trying to exec it fails.
And the usual way that happens is that the assembler (or linker, or
nm) is not found during configure.
Look in the gcc/as script in the build tree, and see if
ORIGINAL_AS_FOR_TARGET is set correctly. If not, look at the logs
generated by the configure step (probably the gcc/config.log one) and
look for the results related to the assembler.

If one hasn't a 'ia64-hp-openvms' target system (like me) where to copy
the target stuff, there is a serious
problem :( Here is one advice for solving this issue :
