CMake CMakeLists.txt:13错误(find_package)：在CMAKE_MODULE_PATH中不提供"FindGeant4.cmake“

Question

我在Linux系统上安装Geant4时遇到了问题。

$ cmake ..
CMake Error at CMakeLists.txt:13 (find_package):
  By not providing "FindGeant4.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Geant4", but
  CMake did not find one.

  Could not find a package configuration file provided by "Geant4" with any
  of the following names:

    Geant4Config.cmake
    geant4-config.cmake

  Add the installation prefix of "Geant4" to CMAKE_PREFIX_PATH or set
  "Geant4_DIR" to a directory containing one of the above files.  If "Geant4"
  provides a separate development package or SDK, be sure it has been
  installed.

我试过：

apt-get install g++

但我明白：

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

Answer 1

您只需获取geant4.sh

在bash中，发出命令：

source /path_to_geant4_install/bin/geant4.sh

然后做cmake

Answer 2

我也有类似的问题。

在.bashrc中添加这些命令可能会有所帮助：

source /home/user/geant4-install directory/bin/geant4.sh

source /home/user/geant4-install directory/share/geant4-version number/geant4make/geant4make.sh

export G4WORKDIR=/home/user/g4work
