EPICS Release base 3.14.0alpha1 Known Problems

Building on solaris sparc with GCC

Building with GCC on solaris does not work. The following helps somewhat.

Make the following changes in <base>/configure/os

diff -r1.4 CONFIG.solaris-sparc.solaris-sparc
< G++_STATIC_LDLIBS_YES= -lposix4
< G++_STATIC_LDLIBS_NO= -lposix4
> GCC_STATIC_LDLIBS_YES= -lposix4 -lpthread -lthread
> GCC_STATIC_LDLIBS_NO= -lposix4 -lpthread -lthread
> G++_STATIC_LDLIBS_YES= -lposix4 -lpthread -lthread
> G++_STATIC_LDLIBS_NO= -lposix4 -lpthread -lthread
After building with these changes on solaris 8 with gcc version 2.95.2 19991024 and then generating exampleApp the following was observed: caExample does work correctly with solaris 6 and a different version of gcc.  The problem is under investigation.

GCC debug build

Another recently discovered R3.14 "known problem" is that the following version of the GNU compiler will not build the alpha release of EPICS w/o  undefined symbols during the link if I specify a debug ( HOST_OPT = NO )
build. There has for some time been a g++ bug where inline functions  show up undefined during a debug build, and it continues in egcs-2.91.66.

Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)

I saw this both on Linux and Solaris 6.
