由于库冲突，CMake 无法生成搜索路径

Question

亲爱的同事们， 我是 LINUX 的新手，正在尝试使用 CMake 构建一个 Geant4 示例。在以下命令之后

$cmake ~/Geant4/geant4.10.05.p01-install/share/Geant4-10.5.1/examples/basic/B1/

我收到此错误消息：

Cannot generate a safe runtime search path for target exampleB1 because files in some directories 
may conflict with libraries in implicit directories:
runtime library [libexpat.so.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
/home/dakar/anaconda3/lib
Some of these libraries may not be found correctly.

警告是正确的，当我运行$ make -j6时，我收到错误消息

/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libSM.so： undefined reference to 
‘uuid_generate@UUID_1.0’
/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libSM.so： undefined reference 
to‘uuid_unparse_lower@UUID_1.0’

以前遇到过此问题，此处详细介绍了一些解决方案：

URL 链接的页面表明，对于 Conda 4.4+，不应发生此问题。我正在使用 Conda 4.6.14，但该页面补充说，如果确实发生：您可以在将 conda 添加到路径之前在.bashrc(或类似(中设置NOCONDA_PATH变量，如下所示：

export NOCONDA_PATH=$PATH
export PATH=$HOME/anaconda3/bin:$PATH

我试过这个，我的.bashrc现在写着：

# >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$(CONDA_REPORT_ERRORS=false '/home/dakar/anaconda3/bin/conda' shell.bash hook 2> /dev/null$
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/home/dakar/anaconda3/etc/profile.d/conda.sh" ]; then
. "/home/dakar/anaconda3/etc/profile.d/conda.sh"
CONDA_CHANGEPS1=false conda activate base
else
#       export NOCONDA_PATH=$PATH
export PATH="/home/dakar/anaconda3/bin:$PATH"
fi
fi
unset __conda_setup
# <<< conda init <<<
export CLHEP_DIR=/home/dakar/CLHEP/2.3.3.2/CLHEP-install/
export CLHEP_INCLUDE_DIR=${CLHEP_DIR}/include/
export CLHEP_LIBRARY=${CLHEP_DIR}/lib/
export LD_LIBRARY_PATH=${CLHEP_LIBRARY}:${LD_LIBRARY_PATH}
export PATH=$CLHEP_DIR/bin/:$PATH
export TOPAS_G4_DATA_DIR=~/G4Data
export LD_LIBRARY_PATH=~/topas/libexternal/:$LD_LIBRARY_PATH
#export LD_LIBRARY_PATH=~/anaconda3/lib/gcc/lib:$LD_LIBRARY_PATH
#CERN ROOT
#export ROOTSYS=/usr/local/root
#export PATH=$ROOTSYS/bin:$PATH
#export PYTHONDIR=$ROOTSYS
#export LD_LIBRARY_PATH=$ROOTSYS/lib:$PYTHONDIR/lib:$ROOTSYS/bindings/pyroot:$LD_LIBRARY_PATH
#export PYTHONPATH=$ROOTSYS/lib:$PYTHONPATH:$ROOTSYS/bindings/pyroot
source ~/Geant4/geant4.10.05.p01-install/bin/geant4.sh
#source ~/Geant4/geant4.10.05.p01-install/share/Geant4-10.5.1/geant4make/geant4make.sh
export NOCONDA_PATH=$PATH
export PATH="/home/dakar/anaconda3/bin:$PATH"

这仍然没有解决问题。当我运行echo $PATH时，我仍然可以看到conda目录：

$ echo $PATH
/home/dakar/anaconda3/bin:/home/dakar/Geant4/geant4.10.05.p01-install/bin:/home/dakar/CLHEP/2.3.3.2/CLHEP-install//bin/:/home/dakar/anaconda3/bin:/home/dakar/anaconda3/condabin:/usr/local/cuda-8.0/bin:/home/dakar/bin:/home/dakar/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

有人有什么进一步的建议吗？卸载康达本身是否是一种解决方案。

谢谢你的时间。 L

错误消息表明链接器调用中缺少 libuuid。

尝试将 -luuid 添加到链接器标志。

您的构建系统是否使用 pkg 配置？在这种情况下，您可以编辑/usr/lib/x86_64-linux-gnu/pkgconfig/sm.pc并将 -luuid 添加到Libs-Section 中。

这看起来像您的Linux发行版中的一个错误。
