Geant4，示例B1构建错误:没有规则可设置目标

Question

我正在为Geant4-10.0.1编译B1示例。此链接提供说明http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/InstallationGuide/html/ch03s02.html。

我有两个独立的dir: B1和B1-build。一切都很正常直到

$ make -jN

我得到以下错误

$ make -j4

有什么想法吗？谢谢。

试过

$ make VERBOSE=1

它以类似的错误消息结束：

还是迷路了。

Answer 1

在安装库之后，我成功地构建了您所引用的B1示例。

我提取了geant4.10.00.p01.tar.gz。

然后

mkdir build && cd build && \
cmake -DCMAKE_INSTALL_PREFIX=../geant4-install ../geant4.10.00.p01 && \
make -j8 && make install

然后我处决了

source ./geant4.sh

在geant4-安装/垃圾箱。

我构建B1示例如下：

cd geant4.10.00.p01/examples/basic/B1 && \
mkdir build && cd build && cmake ../ && make

这就建立了这个例子并将其联系起来。

又一次..。您安装了libexpat吗?/usr/lib64 64/libexpat。那么指向一个有效的共享库？

Answer 2

这意味着你找不到外派图书馆。如果您正在使用expat进行开发，那么您必须安装expat库的dev版本：

sudo apt-get install -y libexpat1-dev

如果您正在使用expat库，而不是用于开发，那么使用下面的命令进行安装：

sudo apt-get install -y expat
