答复: Compiling helloWorld of EPICS V4 on 64bit linux had a link error [SEC=UNOFFICIAL]

[米清茹 <miqingru@sinap.ac.cn>]

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       -m64               HelloServiceMain.o HelloService.o    -lpvAccess -lpvData  -lexpat
/usr/bin/ld: cannot find -lexpat
collect2: ld returned 1 exit status
make[2]: *** [HelloService] Error 1
make[2]: Leaving directory `/BLC/epics/v4/EPICS-CPP-4.3.0/exampleCPP/HelloWorld/helloWorldApp/O.linux-x86_64'
make[1]: *** [install.linux-x86_64] Error 2
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?
