octave standalone , example reports undefined reference to `octave::feval error

Question

When try to the 2nd example https://octave.org/doc/v5.1.0/Standalone-Programs.html#Standalone-Programs I got the following error :

embedded.cc:(.text+0x132): undefined reference to `octave::feval(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, octave_value_list const&, int)'

The -d option of the mkoctfile provides the following two g++ commands, where the 1st one works fine.

g++ -std=gnu++11 -c  -fPIC -I/grid/common/pkgsData/octave-v5.1.0/Linux/RHEL7.0-2017-x86_64/include/octave-5.1.0/octave/.. -I/grid/common/pkgsData/octave-v5.1.0/Linux/RHEL7.0-2017-x86_64/include/octave-5.1.0/octave -I/grid/common/pkgsData/octave-v5.1.0/Linux/RHEL7.0-2017-x86_64/include  -pthread -fopenmp -fPIC    embedded.cc -o /tmp/oct-EYDDih.o

and

g++ -std=gnu++11  -I/grid/common/pkgsData/octave-v5.1.0/Linux/RHEL7.0-2017-x86_64/include/octave-5.1.0/octave/.. -I/grid/common/pkgsData/octave-v5.1.0/Linux/RHEL7.0-2017-x86_64/include/octave-5.1.0/octave -I/grid/common/pkgsData/octave-v5.1.0/Linux/RHEL7.0-2017-x86_64/include  -pthread -fopenmp -fPIC -rdynamic  -fPIC   -o embedded  /tmp/oct-EYDDih.o    -L/grid/common/pkgsData/octave-v5.1.0/Linux/RHEL7.0-2017-x86_64/lib -L/grid/common/pkgsData/octave-v5.1.0/Linux/RHEL7.0-2017-x86_64/lib/octave/5.1.0 -loctinterp -loctave   

Any idea how to solve this ?

我在这个问题的根本原因中发现，加载了一个 EDA 工具（Cadence Xcelium）模块，它让 g++ 指向其私有版本，当我用 /bin/g++ 替换 g++ 时，它在我的环境中工作。
