Hi Marty,

Do you also build your programs linked statically on linux too? If not, it might be worth doing that too - I believe any purely link order issues you may see with travis windows should also occur when linking statically on linux

Regards,

How do I do this on Linux?

I also have a couple of questions about the travis  builds.
1) Why are there two sets of builds,
2) Do  any of the gcc or clang builds statically linked.

Hi Marty,

You are making progress, the error is now different:

/home/travis/.source/pvaClient/lib/linux-x86_64/libpvaClient.a(pvaClient.o): In
function `epics::pvaClient::PvaClient::~PvaClient()':
/home/travis/.source/pvaClient/src/O.linux-x86_64/../pvaClient.cpp:156:
undefined reference to `epics::pvAccess::ClientFactory::stop()'

So now a function in pvaClient is not finding the pvAccess functions.  That is
probably a link order problem.

Try this:

EPICS_BASE_PVA_CORE_LIBS =  pvaClient  pvDatabase pvAccess pvAccessCA
pvData Com

Or leave EPICS_BASE_PVA_CORE_LIBS as it was originally and add pvaClient
here:

PROD_HOST += serviceMain
serviceMain_SRCS += serviceMain.cpp
serviceMain_LIBS += controlRecord
serviceMain_LIBS += powerSupplyRecord
serviceMain_LIBS += linkRecord
serviceMain_LIBS += pvaClient
serviceMain_LIBS +=  $(EPICS_BASE_PVA_CORE_LIBS)

Mark

Mark,

I made that change.
The pull request still fails for windows and rtems.

Does it build for You on windows?
