RE: Problem compiling epicsOnce.cpp

[Mark Rivers <rivers@cars.uchicago.edu>]

Others had that same problem building base 3.14.12.1.

The problem is presumably fixed in more recent versions of EPICS base.  Can you upgrade to a more recent version?

The APEX project here is using R3.14.12.1 with EPICS_HOST_ARCH=linux-x86_64.   Everything up until now has been built with gcc-4.4.6.  I’m now trying to get the Galil motor support running.  This requires a more modern GCC to support the std=c++11 option.  I’ve installed gcc-4.9.3, but when I try to rebuild base I get:

remote/hpcs-sw/RHEL-6.x86_64/gcc/4.9.3/bin/g++ -c  -D_POSIX_C_SOURCE=199506L -D_POSIX_THREADS -D_XOPEN_SOURCE=500           -D_X86_64_  -DUNIX  -D_BSD_SOURCE -Dlinux  -D_REENTRANT   -O3   -Wall      -m64     -g -fPIC -MMD -I. -I../O.Common -I. -I../../../src/libCom/osi/os/Linux -I../../../src/libCom/osi/os/posix -I../../../src/libCom/osi/os/default -I.. -I../../../src/libCom/bucketLib -I../../../src/libCom/ring -I../../../src/libCom/calc -I../../../src/libCom/cvtFast -I../../../src/libCom/cppStd -I../../../src/libCom/cxxTemplates -I../../../src/libCom/dbmf -I../../../src/libCom/ellLib -I../../../src/libCom/env -I../../../src/libCom/error -I../../../src/libCom/fdmgr -I../../../src/libCom/freeList -I../../../src/libCom/gpHash -I../../../src/libCom/iocsh -I../../../src/libCom/logClient -I../../../src/libCom/macLib -I../../../src/libCom/misc -I../../../src/libCom/osi -I../../../src/libCom/taskwd -I../../../src/libCom/timer -I../../../src/libCom/tsDefs -I../../../include/os/Linux -I../../../include        ../../../src/libCom/cxxTemplates/epicsOnce.cpp

I’ve tried rebuilding just the Galil support module with gcc-4.9.3 and linking against the gcc-4.4.6-compiled version of base, but this core dumps when attempting to start an IOC.  Differences in the C++ runtime, I expect.

 

Suggestions?
