Hi, I had installed geant4.10.04.p01 few months ago. That time I was able to build and run exampleB1. But now when I try to build the same using cmake, it shows the following error message: skrout@Saraswati:~/g4work/B1-build$ cmake -DGeant4_DIR=$G4DIR ../B1 -- The C compiler identification is GNU 4.8.5 -- The CXX compiler identification is GNU 4.8.5 -- Check for working C compiler: /usr/bin/gcc -- Check for working C compiler: /usr/bin/gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/g++ -- Check for working CXX compiler: /usr/bin/g++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Configuring done -- Generating done -- Build files have been written to: /home/skrout/g4work/B1-build skrout@Saraswati:~/g4work/B1-build$ make Scanning dependencies of target exampleB1 [ 12%] Building CXX object CMakeFiles/exampleB1.dir/exampleB1.cc.o [ 25%] Building CXX object CMakeFiles/exampleB1.dir/src/B1PrimaryGeneratorAction.cc.o [ 37%] Building CXX object CMakeFiles/exampleB1.dir/src/B1EventAction.cc.o [ 50%] Building CXX object CMakeFiles/exampleB1.dir/src/B1DetectorConstruction.cc.o [ 62%] Building CXX object CMakeFiles/exampleB1.dir/src/B1ActionInitialization.cc.o [ 75%] Building CXX object CMakeFiles/exampleB1.dir/src/B1SteppingAction.cc.o [ 87%] Building CXX object CMakeFiles/exampleB1.dir/src/B1RunAction.cc.o [100%] Linking CXX executable exampleB1 CMakeFiles/exampleB1.dir/src/B1PrimaryGeneratorAction.cc.o: In function `B1PrimaryGeneratorAction::GeneratePrimaries(G4Event*)': B1PrimaryGeneratorAction.cc:(.text+0x342): undefined reference to `G4Exception(char const*, char const*, G4ExceptionSeverity, std::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> >&)' collect2: error: ld returned 1 exit status CMakeFiles/exampleB1.dir/build.make:295: recipe for target 'exampleB1' failed make: *** [exampleB1] Error 1 CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/exampleB1.dir/all' failed make: *** [CMakeFiles/exampleB1.dir/all] Error 2 Makefile:127: recipe for target 'all' failed make: *** [all] Error 2 Since I had previously run it without any error, I think there is some minor issue which doesn't require me installing geant4 all over again. Please help me fix it. Thanks, Sandeep [ MIME part of type text/html without a name stripped ]
