Why the following error has occurred when I try to program FPGA? I use Altera board DE1_SoC. OS Ubuntu 18.04 and IntelFPGA 18.1 standard version.

Hi ,

If you can try the compilation on Ubuntu 16.04 or 18.04 that would be helpful , since the issues of compatibility of GLIBC can be avoided.

You can also check which version of GLIBC is currently installed in your system to cross verify.

Thanks and Regards
