ubuntu安装spyglass提示SPYGLASS_HOME

安装spyglass后运行sg_shell，提示以下内容：

spyglass: INTERNAL-ERROR, the VALUE OF `$SPYGLASS_HOME' (an internal variable) was not intuited correctly.
spyglass:                 The value guessed was: `SPYGLASS_HOME=/usr/cad/SpyGlass-4.4.0/SPYGLASS_HOME'
spyglass: INTERNAL-ERROR, the Perl 5 installation within `$SPYGLASS_HOME' could not be validated.
spyglass:                 A perl installation was expected at: `/usr/cad/SpyGlass-4.4.0/SPYGLASS_HOME/lib/multi-perl'
spyglass:                 either `$SPYGLASS_HOME' was guessed incorrectly or the installation is corrupted.
spyglass: NOTE, the caller's environment variable `$SPYGLASS_HOME' was ignored in this process

有哪位大神遇到过这种问题，求指导，多谢！

没有设置sypglass的home目录 ，需要修改~/.bashrc文件：
export SPYGLASS_HOME=/xxx/spyglass/SpyGlass-L2016.06/SPYGLASS_HOME/
export PATH=$PATH:$SPYGLASS_HOME/bin

类似于导入安装包的路径和变量，用户可使用；

Hi friends,

This is for the the people facing error
spyglass: INTERNAL-ERROR, the Perl 5 installation within $SPYGLASS_HOME' could not be validated. spyglass: A perl installation was expected at:/home/h/software/synopsys/SpyGlass-L2016.06/SPYGLASS_HOME/lib/multi-perl'
spyglass: either $SPYGLASS_HOME' was guessed incorrectly or the installation is corrupted. spyglass: NOTE, the caller's environment variable$SPYGLASS_HOME' was ignored in this process.

Solution:
I am assuming that you have configured $SPYGLASS_HOME variable.

This issue may be due to updated or latest linux kernel version 4.*.
Spyglass 2016 expects linux kernel version 3.

If you want to use linux kernel version 4 then do two changes in scripts.
Please take backup of original files.
standard-environment.sh & perl files need to be modified.

1. Look for standard-environment.sh file in SPYGLASS_HOME/lib/SpyGlass. Open that file in text editor and search for Linux-3*. Add new entry Linux-4*) after fi ;; and before *) echo UNKNOWN ;; . I have shown it below.

Linux-3*)
if [ X"$switch32bit" = "Xyes" ]; then
echo "Linux2"
elif [ X"$switch64bit" = "Xyes" ]; then
PROCNAME=uname -p
if [ "X$PROCNAME" = "Xunknown" ]; then
PROCNAME=uname -m
fi
if [ X"$PROCNAME" = "Xx86_64" ]; then
echo "Linux4"
else
echo "Linux2"
fi
else
PROCNAME=uname -p
if [ "X$PROCNAME" = "Xunknown" ]; then
PROCNAME=uname -m
fi
if [ X"$PROCNAME" = "Xx86_64" ]; then
if [ X"$defExeOn64Bit" = "X32" ]; then
echo "Linux2"
else
echo "Linux4"
fi
else
echo "Linux2"
fi
fi
;;
Linux-4*)
if [ X"$switch32bit" = "Xyes" ]; then
echo "Linux2"
elif [ X"$switch64bit" = "Xyes" ]; then
PROCNAME=uname -p
if [ "X$PROCNAME" = "Xunknown" ]; then
PROCNAME=uname -m
fi
if [ X"$PROCNAME" = "Xx86_64" ]; then
echo "Linux4"
else
echo "Linux2"
fi
else
PROCNAME=uname -p
if [ "X$PROCNAME" = "Xunknown" ]; then
PROCNAME=uname -m
fi
if [ X"$PROCNAME" = "Xx86_64" ]; then
if [ X"$defExeOn64Bit" = "X32" ]; then
echo "Linux2"
else
echo "Linux4"
fi
else
echo "Linux2"
fi
fi
;;

 *)             echo UNKNOWN ;;

2. After this open perl from root installation directory.
   From that open "perl" script in text editor. Again look for Linux-3* and add following code after fi ;;

Linux-4*) ##now we have Linux-64 bit also
PROCNAME=uname -p
if [ "X$PROCNAME" = "Xunknown" ]; then
PROCNAME=uname -m
fi
if [ X"$PROCNAME" = "Xx86_64" ]; then
species=Linux4
else
species=Linux2
fi
