about SpiderMonkey cross compile

[Tony Wang-2]

Hi all,

I am cross compile SpiderMonkey for my ARC-Linux platform, I got the
lastest JS source code from the Mercurial repository, and i could find
the configure.in file in js/src dir.

I build it according to https://developer.mozilla.org/en/Building_only_SpiderMonkey,
here comes my cross-compile process:
1, export CC=arc-linux-uclibc-gcc
    export CXX=arc-linux-uclibc-g++
2, I mkdir arcbuild in js/src, and new one build file in it, as
follows:
../configure --prefix=/opt/webkitrelease --build=i686 --host=arc-linux-
uclibc --target=arc-linux-uclibc --with-dirctfb --without-x --disable-
tests --enable-static --enable-js-static-build --disable-shared
3, then in js/src/arcbuild, i run commands:
  [root@bogon arcbuild]# ./build
  [root@bogon arcbuild]# make
4, then i got following results:
----------------------------------------------------------------------------------------------------------------
/usr/bin/gmake export

I know that we build nsinstall file by arc-linux-uclibc-gcc, while we
run it i686-linux, so we got the "cannot execute binary file" error.

Can anyone tell me how to change the C compile for nsinstall? or how
to adapt the Makefile?

Thanks in Advance,
Tony

When did you try this last? I believe that prior to a few days ago, you
needed to export CROSS_COMPILE=1 in your environment. Please try that, or
try updating your sources to the very latest.

Yeah, we're supposed to compile it for the host... if my suggestion above
doesn't work, please report back and we can try a few more things.

Thanks, Ben

I tried again by adding export CROSS_COMPILE=1, but got the same
error.

BTW, I got the source code from Mercurial repository yesterday, Dec
18, 2008.

In your object directory, look at the contents of the config/autoconf.mk
file: it should have a line

CROSS_COMPILE =

or

CROSS_COMPILE = 1

which value do you see?

When is the last time you ran autoconf-2.13 to regenerate your configure script?

Yeath，i see CROSS_COMPILE = 1.
[root@bogon src]# ll configure
-rwxr-xr-x 1 root root 384621 Dec 19 16:55 configure
we can get that the last time i ran autoconf-2.13 to generate
configure is Dec 19, 2008.

So, interesting, from your original post:

gmake[2]: Entering directory `/home/mozilla-central-eb18fff240df/js/
src/arcbuild/config'
nsinstall.c
arc-linux-uclibc-gcc -o host_nsinstall.o -c -DXP_UNIX -O3  -I../../
config -I.  -I../dist/include   -I../dist/include  -I/sdk/
include  ../../config/nsinstall.c
pathsub.c

This indicates that you are building *host* programs with arc-linux-uclibc-gcc

In autoconf.mk, what is the value of HOST_CC?

If it is wrong, try setting HOST_CC explicitly in your environment when
configuring, e.g.

export HOST_CC=/usr/bin/gcc

Now i could cross-compile SpiderMonkey source form mozilla-central-
eb18fff240df/js separately.
BTW, we should also set HOST_CXX=/usr/bin/g++ in autoconf.mk.

Thanks & Merry Chrismas,
Tony
