Hi Lynch, Jani, Hinko,
You are right! The expat-devel package hasn't installed. After I installed the expat-devel package with yum, libexpat.so was also installed into /usr/lib64.
Thank you very much!

Hi Qingru,
Glad to hear it’s working. I suspect the real problem is the expat-devel package is not installed.

Hi Lynch,
There wasn't libexpat.so. After I created the link, the HelloWorld was built without any error.
Thank you very much!

Although you don’t mention libexpat.so. Does that exist? If not you could create it as a link to libexpat.so.1.

Sorry, ignore that I missed
I can find libexpat.so.1 and libexpat.so.1.5.2 in /lib64 in your message.
Hi,
I assume expat is the Expat XML parser library. Do you have that installed?

Hi,
I compiled the EPICS-CPP-4.3.0 on 64bit centos6.5. As the HelloWorld in exampleCPP was compiled, an error occured. The error information shows below:
/usr/bin/g++ -o HelloService -L/BLC/epics/v4/EPICS-CPP-4.3.0/pvAccessCPP/lib/linux-x86_64 -L/BLC/epics/v4/EPICS-CPP-4.3.0/pvDataCPP/lib/linux-x86_64 -Wl,-rpath,/BLC/epics/v4/EPICS-CPP-4.3.0/pvAccessCPP/lib/linux-x86_64 -Wl,-rpath,/BLC/epics/v4/EPICS-CPP-4.3.0/pvDataCPP/lib/linux-x86_64

/usr/bin/ld: cannot find -lexpat

make[1]: Leaving directory `/BLC/epics/v4/EPICS-CPP-4.3.0/exampleCPP/HelloWorld/helloWorldApp'
make: *** [helloWorldApp.install] Error 2
I can find libexpat.so.1 and libexpat.so.1.5.2 in /lib64.
How to resolve the problem?
