Ron,
It took a few weeks, but I have something small and repeatable:
#include <boost/multi_array.hpp>
int main()
{
}
Put this in a file called go.cpp. Then compile with:
g++32 -g -Wall -c go.cpp -o go.o -I/usr/include/c++/boost_1_34_1
where g++32 -v yields:
Reading specs from /usr/lib/gcc-lib/x86_64-redhat-linux/3.2.3/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit
--enable-languages=c,c++ --disable-libgcj --host=x86_64-redhat-linux
Thread model: posix
gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-47.3)
and this is a 64-bit machine:
Linux blah.blah.com 2.6.9-42.0.10.ELsmp #1 SMP Tue Feb 27 09:40:21 EST 2007
x86_64 x86_64 x86_64 GNU/Linux
You ought to get the same error listed below.
Thanks,
