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? Qingru Mi SSRF |
