Hi,

looking at the SL6.3 installation, I got my libexpat from the package named ‘expat’.

[devenv@localhost ~]$ repoquery -ql expat
/lib/libexpat.so.1
/lib/libexpat.so.1.5.2
/usr/bin/xmlwf
/usr/share/doc/expat-2.0.1
/usr/share/doc/expat-2.0.1/COPYING
/usr/share/doc/expat-2.0.1/README
/usr/share/man/man1/xmlwf.1.gz
/lib64/libexpat.so.1
/lib64/libexpat.so.1.5.2
/usr/bin/xmlwf
/usr/share/doc/expat-2.0.1
/usr/share/doc/expat-2.0.1/COPYING
/usr/share/doc/expat-2.0.1/README
/usr/share/man/man1/xmlwf.1.gz


Hope that helps,
Hinko

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

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?
