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
68,71c68,71
< GCC_STATIC_LDLIBS_YES= -lposix4
< GCC_STATIC_LDLIBS_NO= -lposix4
< 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:

example (the example iocCore) seems to work properly. CA clients build on 3.13 or using SUNWspro work.
caExample, the CA client, core dumps. A modified version showed that the core dump occurs the first time ca_pend_io or ca_pend_event is called

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.

Instructions were not in the README.htm. A paragraph on R3.13 compatibility has been added.
