Antwort: Re: problem building cross-gcc for lynxos

[Michael2.Roth]

First of all: many thanks, Kai, I now have a much better understanding of what
problems might be involved when building a cross-GCC!

Regarding the lynxos gcc, the --with-gnu-as switch improved things very much!
The linker is no longer called with the -P1000, and with the target libraries it
is possible to compile and link for lynxos.
However, when making the GCC, at some stage it starts configuring for the
libraries, the system completely hangs during configure (well, I must admit that
I was compiling under cygwin ...). So I had to kill the NT command shell, start
a new one, run make install  - but at least after that the cross compiler could
be used.

Thanks again,
Michael

 Please use at least the '--with-gnu-as'. This puts the configuration to use the
'gcc/config/i386/lynx.h' main config file, not the 'gcc/config/i386/lynx-ng.h',
which is for the old LynxOS 'as' and 'ld'. Please browse the 'gcc/configure'
and search for 'lynxos', then you will see the 'i[3456]86-*-lynxos*' config
entry and these things defined there. Please also browse the
'gcc/config/i386/lynx-ng.h'
and see the '-P1000' being there in LINK_SPEC (not in LD_SPEC as I remembered
the
name to be...)

Cheers, Kai
