[Linux-ia64] gcc 3.0.2 questions

[Linux-ia64] gcc 3.0.2 questions

[Jim Hollenback]

Before I go digging around in a bunch of code thought I would ask.

I'm attempting to build gcc3.0.2 for cross compiling. Specifically
to run on a IA-32 system for building IA-64 bits. During the
configure stage it seems configure and then trys to configure fastjar.
Is this for java? Anyhow it fails with

checking whether struct tm is in sys/time.h or time.h... (cached) time.h
checking size of char... configure: error: can not run test program while cross
compiling
Configure in /usr/src/gnu/build-gcc/fastjar failed, exiting.

Is there anyway if disabling this?

Being the curious type I went ahead and tried to compile. Ended up with

rm -f obstack.c
ln -s ../../gcc-3.0.2/gcc/../libiberty/obstack.c obstack.c
gcc -c -DCROSS_COMPILE -DIN_GCC    -O2 -W -Wall -Wwrite-strings -Wstrict-pro

./gengenrtl -h >tmp-genrtl.h
make[1]: *** [s-genrtl] Error 4
make[1]: Leaving directory `/usr/src/gnu/build-gcc/gcc'
make: *** [all-gcc] Error 2

Is this related to the fastjar failure.

[Boehm, Hans]

How did you configure the compiler?  I believe fastjar is needed only for
Java.

I wouldn't recommend using the 3.0.2 compiler for Java on Itanium.  I
haven't tried it, but I believe it has serious problems with generating
object layout information for the garbage collector.  3.0 and 3.0.1 are
probably more functional.

If you want the Java compiler, your best bet at this stage is probably the
3.1 cvs tree and asking me for some patches.  But I haven't built an IA32 to
IA64 cross-compiler in a long time.

If you rename the fastjar directory in your source tree, then configure
won't find it.  fastjar should configure OK for a simple cross compiler
though.

This isn't caused by the fastjar problem.  However, it may be failing for
the same reason.

gengenrtl is the first program run on the build machine when doing a gcc build.
If gengenrtl fails, then that may indicate that your configure build, host,
and/or target options are wrong.  That same problem could have caused the
fastjar configure error.

How did you configure the cross compiler?  Check the config.status and
gcc/config.status files to make sure that the build/host/target options are
what you expected.
