Hi all,
I get in trouble when building the base-3.14.beta1 on sparc solaris with gcc(++).

Perhaps someone has an idea what happens

I tried the compilation on another sparc

"SunOS host2 5.7 Generic_106541-15 sun4u sparc SUNW,Ultra-1"
"gcc -v
Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.95.2/specs
gcc version 2.95.2 19991024 (release)"
without shared library support, but error messages are quite the same.
The library libcas.a is build and when linking excas I received
messages about douplicated symbols:

Any ideas or suggestions?

Another qaint problem:

Also I build the base-3.14.beta1 on linux with Suse7.3 without any problems.
I compiled  my database, started it  and this runs on up today (6 weeks).
I compiled the medm and I can access with the slider my pvs.
Next I tried to access the pvs from my Sparc with ia simple tool which
will read and write all kind of variables from command line. This goes well,
too.
Last week I ported this tool to linux. And the effect is I can read all pvs
from the linux database, but I can't write any. Does anyone had a similar
behavior and had found a solution for this (my) problem.

Cheers
