Обсуждение: help: cross compiling PG7.4.1 on IA64 from IA32

Hello,

I have been trying unsuccessfully to get PG 7.4.1 built for an IA64
environment using the following:

Redhat Taroon (IA64) beta headers and libs installed in
/usr/local/ia64-linux
Build host: Redhat 9 I386
Build Target: ia64-linux
binutils: 2.14 built using IA64 headers (as above)
gcc:3.3.3 built using IA64 headers and binutils above, built using --sysroot
to /usr/local/ia64-linux

Configure script for PG7.4.1:
./configure \
--prefix=/opt/sonar/DB64 \
--with-java \
--enable-thread-safety \
--build=i686-pc-linux-gnu \
--host=ia64-linux \
--with-libraries=/usr/local/ia64-linux/lib \
--with-libs=/usr/local/ia64-linux/include \
LDFLAGS=-L/usr/local/ia64-linux/lib \
CPPFLAGS=-I/usr/local/ia64-linux/include

What I get when compiling PG is the following error trying to find
/lib/libpthread.so.0. It doesn't seem to be able to find my IA64 version of
this library, even though all the other libraries seems to be found okay.
The IA64 version of this libaries is definately there
(/usr/local/ia64-linux/lib).

Any ideas appreciated.

Hmm, PG builds fine for me in Red Hat's RPM build environment.  Would
you like to try downloading the 7.4.2 RPM or SRPM from fedora.redhat.com?

            regards, tom lane

Yep, PG 7.4.1 installs fine on a native IA64 box, but not when cross
compiling on a IA32 box for IA64. Regardless of what I do, PG always seem to
want to link libpthread from /lib (which is the IA32 version) and ignores
the LDFLAGS directive pointing it at /usr/local/ia64-linux/lib. I'm
suspecting this is hardcoded somewhere in the GCC environment because even
when I explicitly tell it to link to the IA64 lib, it completely ignores it.

I asked about cross-compiling inside Red Hat and was told:

: this can only work if you build a cross compile toolchain; it
: doesn't look like he did that. (note we don't ship nor support such a
: thing).

So my guess is there's something wrong with your cross-compilation
setup.  What exactly is wrong is beyond my field of expertise ...
you might try asking some gcc-oriented mailing list.
