Experimental Physics and Industrial Control System
I'm building this native-only version on solaris-sparc-gnu (Solaris 8).
The build faults on trying to build libcas.so , because the linker
complains about multiply-defined entry points, apparently from
caServerI.cc and casEventMask.cc . The detailed message from the
build is attached below.
As for my setup...
In CONFIG_SITE, I've turned on the build of dynamic libraries, and turned
off the build of vxworks targets.
In os/CONFIG_SITE.solaris-sparc-gnu.solaris-sparc-gnu, I add the following
overrides:
GNU_DIR = /usr/local
LD = /usr/ccs/bin/ld -r
DEPLIB_DIRS += /usr/local/lib
SHRLIB_LDFLAGS_YES = -Wl,-G -Wl,-dy
These are because our gcc/g++ is built to use Solaris as/ld instead of
the GNU binutils versions. (The last line overrides the default -share
in shared library builds, which would introduce -z text to ld in
addition to the desired -G and -dy . The -z text breaks the build
of libca.so .)
Other than those changes, it's the vanilla build system. The problem
is shown below. Can anybody help?
