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来构建一个Geant4示例。在下面的命令之后

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

我收到这个错误消息：

  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，我得到错误消息

    /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’

这个问题以前也遇到过，这里将详细介绍一些解决方案：

URL链接的页面指出，对于Conda 4.4+，不应该出现此问题。我使用的是Conda 4.6.14，但页面补充说，如果确实发生了这种情况:您可以在将conda添加到路径之前在.bashrc (或类似的)中设置NOCONDA_PATH变量，如下所示：

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

我试过了，我的.bashrc现在显示为：

# >>> 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

还有人有什么进一步的建议吗？卸载Conda本身就是一种解决方案。

耽误您时间，实在对不起。我

该错误消息表明您的链接器调用中缺少libuuid。

尝试将-luuid添加到您的链接器标志。

您的构建系统是否使用pkg-config？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。

这看起来像是你的Linux发行版中的一个bug。
