(My mail is getting mangled lately. We'll see..)
-with/without-gnu-ld/as build vs. host?
I already did:
build=cygwin
host=cygwin
target=sparc64-solaris
binutils and gcc
I want to do the following:
build=cygwin
host=sparc64-solaris
target=sparc64-solaris
only gcc, will use native ld/as
This seems..problematic.
/usr/local/lib/gcc/sparc64-sun-solaris2.10/4.3.2/../../../../sparc64-sun-solaris2.10/bin/ld:
libgcc.map: file format not recognized; treating as linker script
/usr/local/lib/gcc/sparc64-sun-solaris2.10/4.3.2/../../../../sparc64-sun-solaris
2.10/bin/ld:libgcc.map:1: syntax error
collect2: ld returned 1 exit status
I searched the web..I see this is due to confusion as to if GNU or Sun ld are being used.
It seems like I might want to say:
-without-host-gnu-ld -without-host-gnu-as -with-build-gnu-as -with-build-gnu-ld
I'm still trying some variations.
For the map error, since this is run on the build machine, it seems it could "just"
probe for the expected input? You know, try both, see which works?
I'm sure I can just bootstrap with -disable-shared on build=cygwin,
and then build native on Solaris without -disable-shared.
I can't bootstrap on Solaris with the Sun compiler due to a problem in the gcc source.
I was avoiding resorting getting more prebuilt binaries, but that'd work too.
Two other problems I ran into today:
You an say gcc/configure -with-sysroot, then bring that gcc
over to the Solaris machine, and it passes -sysroot to Sun ld which rejects it.
Upon which you have to -dumpspecs, edit, -specs.
Or go reconfigure and rebuild. Or reconfigure and nicely incrementally build?
It seems a bit off to me, but I don't know.
Another problem is at first I hadn't built binutils.
Gcc goes ahead and builds fixincludes, libiberty, gcc, and then finally
it fails in libgcc. Oops. So I go and build binutils.
But I also have to delete the dummy as script that gcc created.
It'd be nice, somehow, if it could warn/error for the missing binutils earlier,
or at least recover somehow more automatically.
I don't know. Maybe it has to be the way it is. I'm not necessarily going to
build libgcc if I configure gcc, warnings will be missed, and I'll always
want errors earlier and earlier, and they can't all be instantaneous.
