Shalom,

Wondering why we're using the bash shell here, it may be contributing to the problem.

These errors point to the following general issues:
1) Problem with the gcc install, perhaps missing run time required programs.
2) System patching. Bi-annual update usually helps.

Hello,

Link the C++ libraries accordingly.

For example, adding "--LINK=c++ -lstdc++" to the linker options.

Thanks

I install some system patchings, but still came up against the same problem, it trouble me so much, can anyone help me?

Thanks!

What command were you using?
The 8 warnings are defined in -lunwind.
And so is that error.

You should probably be linking with g++, not gcc.
