[Gm2] Re: Intel-Mac build problem

[Gaius Mulley]

Hi Jim,

on a PPC Mac platform (Darwin Kernel Version 8.11.0) I can build
stage1 correctly, but when I try to build make gm2.paranoid I get the
following unresolved references.


gcc   -g -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes  -fno-common   -DHAVE_CONFIG_H  -o

However when I attempt to build hello world (using stage1) I get:

$ make
gm2 -c -g -I. hello.mod
gm2 -g -I. hello.mod
/usr/bin/ld: Undefined symbols:
__Unwind_Resume
collect2: ld returned 1 exit status
make: *** [all] Error 1

I've just checked in a patch for gm2/gm2spec.c to include linking
against -lgcc_eh.  However it does not appear to work yet.  It
is possible to force a correct linkage if I use the following
command line:

 gm2  -g -I. hello.mod  -lgcc_eh

It isn't the problem your seeing though..  has anyone else seen
the "_force_no_linker" problem?

regards,
Gaius
