I'm trying to build a GCC 3.1 cross compiler (from the head of GCC
CVS) from Mac OS X 10.1.2 to Win32 (MinGW). When I do so, get get
errors from the libtool script for the objc runtime (which I need).
This occurs whether I enable shared libraries or not (the erroring
section seems to be related to shared library support).
The offending code starts with:
archive_expsym_cmds="if test \\"x\\`head -1 \$export_symbols\\`\\" =
xEXPORTS; then
cp \$export_symbols \$output_objdir/\$soname-def;
else
echo EXPORTS > \$output_objdir/\$soname-def;
...
On Darwin I get:
./libtool --mode=compile
/Users/Shared/bungi/Build/Intermediates/MinGW/builds/gcc/gcc/xgcc

head: : No such file or directory
./libtool: command not found: \[$]2 [214]
./libtool: no such file or directory: \ >> $output_objdir/$soname-
def;;\n *) echo \ [215]
expr: non-numeric argument
... lots more errors ...
This looks like the 'head' command is being executed by /bin/sh even
though it is being quoted. So, I installed the latest bash and
modified the libtool script above to use that bash executable. In this
case I get a different error (complaining about unexpected end of input)
but I still get errors.
Is this a known bug? Any suggestions would be helpful.
Thanks!
