Problme building gcc cvs trunk on sparc64-linux: gcc/real.h:67: error: size of array `test_real_width' is negative

[Christian Jönsson]

This was on a Aurora SPARC Linux 0.32 build (Nashville) Ultra1
sun4u system with these packages:

binutils 2.13.90  (Wed Oct  9 20:29:45 UTC 2002 cvs trunk)
dejagnu-1.4.3-0   (built ftp://ftp.gnu.org/gnu/dejagnu/dejagnu-1.4.3-0.src.rpm)
expect-5.38.0-74  (from rawhide)
gcc 3.2.1	  (Thu Oct  3 07:52:57 UTC 2002 cvs branch)
glibc-2.2.5-36
kernel-2.4.18-0.998sparc
tcl-8.3.3-74      (from rawhide) 


In-tree joined gcc and binutils cvs trunks.


When trying to compile gcc and binutils I get the following error:

BOOT_CFLAGS='-g -O2 -m64 -mtune=ultrasparc -pipe'

Please not that this is for target sparc64-linux and that I use the
-m64 switch to the bootstrap of stages 2 and 3. (Is -m64 appropriate?)

Cheers,

If your system "gcc" is not building 64-bit binaries in the first
stage of the bootstrap, you cannot use the target sparc64-linux.

The first stage and the gcc you are creating, must be generating code
for the same ABI during a host build.  In this case sparc 32-bit or
sparc 64-bit.

Thanks for your reply. I've kept the BOOT_CFLAGS as is and I'm now
configuring like this:

export BOOT_CFLAGS='-g -O2 -m64 -mtune=ultrasparc -pipe'
env CC='gcc -m64 -mtune=ultrasparc' \
LD_LIBRARY_PATH=/usr/local/gcc-binutils/lib:/usr/lib64 \
/usr/local/src/gcc-binutils/trunk/gcc-binutils/configure \
sparc64-linux --prefix=/usr/local/gcc-binutils \
--enable-shared --enable-threads=posix
