[Bug other/37036] New: fixincludes does not understand sysroot!

gcc 4.3.1

given build=platform1 (i686-pc-cygwin)
given platform2 (sparc-sun-solaris2.10) 

mkdir /obj
mkdir /obj/1
cd /obj/1
# ensure up to date native tools
/src/gcc/configure -build platform1 -host platform1 -target platform1
-disable-bootstrap -disable-multilib -enable-languages=c,c++ && make && make
install


# cross tools -- have setup sysroot ahead of time
mkdir /obj/2
cd /obj/2
/src/gcc/configure -build platform1 -host platform1 -target platform2
-disable-bootstrap -disable-multilib -enable-languages=c,c++ && make && make
install

# now the problem part
mkdir /obj/3
cd /obj/3
/src/gcc/configure -build platform1 -host platform2 -target platform2
-disable-bootstrap -disable-multilib -enable-languages=c,c++ ???? && make &&
make install
DESTDIR=/usr/local/platform2/install

tar up the install
scp
untar on host
try it out

errors, because fixincludes uses the build /usr/include instead of the
sys-rooted /usr/include.

Even using -with-build-sysroot /usr/local/platform2/sys-root does not work.
Apparently. I have to go read the code.

Specific workaround:
delete include-fixed/math.h


I think this is particularly problematic in that the requirements here are
"unique". Nowewhere else does the two platform canadian cross need the
host/target sysroot. It's builtin to the cross compiler.

The cross ocmpiler also has the correctly fixed includes.
So another workaround is to use them.
But they might be from an older version of gcc/fixincludes.

wait, um, maybe -with-build-sysroot= works, with an equals sign. I'll try that.

Running fixincludes on the host after install works, but

says that is not the way..

Here is a lame workaround that works, from my Python wrapper:

    if (Host == Target) and (Host != Build):
        ExtraConfig += " -with-sysroot=/"
        ExtraConfig += " -with-build-sysroot=" + DefaultSysroot

Any progress on this?

I'm sorry the Python is surely very long gone. It was so many years ago.

It was a wrapper around a series of configure + make
to build several gcc toolsets, i.e. native, cross, etc.

At the time I had Solaris and/or VMS sysroots.
I was probably hosting on Cygwin, and was annoyed with gmp/mpfr as well.

If it was today, well, I'd probably just Zig as a cc/ld driver. :)

I'll login later and put that in the bug once I reset password etc.

To be clear, is that a wrapper around GCC or fixincludes? In either case, can
you link us to your Python wrapper?
