samba - Nov 2005 - Cannot cross-compile 3.0.20b from i686 to mipsel

Hi.

I'm trying to compile 3.0.20b on my i686 host to run on a
mipsel host. For this, I got a cross compile toolchain from
<http://linkstationwiki.org/Projects/CrossToolchains>. The
toolchain is installed at
/usr/local/linkstation/gcc-3.3.5-glibc-2.3.2/mipsel-hdhlan-linux

I ran configure with the help of a little wrapper script:

version=gcc-3.4.4-glibc-2.3.5
#version=gcc-3.3.5-glibc-2.3.2

xd=/usr/local/linkstation/$version/mipsel-hdhlan-linux/bin

export PATH=$PATH:$xd

target=mipsel-hdhlan-linux

CC=$xd/mipsel-hdhlan-linux-gcc
CPP=$xd/mipsel-hdhlan-linux-cpp
LD=$xd/mipsel-hdhlan-linux-ld
AR=$xd/mipsel-hdhlan-linux-ar
NM=$xd/mipsel-hdhlan-linux-nm
OBJDUMP=$xd/mipsel-hdhlan-linux-objdump

export CC CPP LD AR NM OBJDUMP

./configure --host=$target --target=$target     \
        --disable-cups --without-ldap --without-ads     \
        && make AR=mipsel-hdhlan-linux-ar CC=mipsel-hdhlan-linux-gcc	\
	 LD=mipsel-hdhlan-linux-ld NM=mipsel-hdhlan-linux-nm 	\
	OBJDUMP=mipsel-hdhlan-linux-objdump

configure failed with this error message:

checking for open64... yes
checking for _open64... no
checking for __open64... yes
checking for creat64... yes
checking for prctl... yes
configure: error: cannot run test program while cross compiling
See `config.log' for more details.

In config.log I find the following error:

configure:19052: checking for _open64
configure:19109:
/usr/local/linkstation/gcc-3.4.4-glibc-2.3.5/mipsel-hdhlan-linux/bin/mipsel-hdhlan-linux-gcc

/tmp/ccaUm9zZ.o(.data.rel+0x0): undefined reference to `_open64'
collect2: ld returned 1 exit status
configure:19115: $? = 1
configure: failed program was:

What do I do now?

Thanks,

Alexander Skwar

Hello Alexander,

these are quite normal messages when trying to cross-compile bigger 
projects.

Actually you'll find in the config.log, that the configure script tried 
to execute a programm it has recently build.
Running a mips binary on a i686 fails of course.

To fix it, you have either to hack the configure script or - better -
pre-set the variables the configure script wants to figure out.

On my arm plattform it looks like this:

export samba_cv_HAVE_MEMORY_KEYTAB=yes
export samba_cv_USE_SETEUID=no
...

Sometimes it's a bit tricky to find the right variables but searching 
the configure script for those "cannot run test program ..." is
allways
a good start.

Bye,

Martin
