Installation (Linux) RISCV GNU Toolchain error: C compiler cannot create executables, recipe for target 'configure-target-libgomp' failed
 

Hello,

I am trying to install the RISCV GNU Compiler Toolchain. I'm currently stuck on in the Installation (Linux) phase below the Installation (Newlib) phase. I've followed the instructions as is and have got the following error:

Could you please help me find the source of this error and how to rectify it. I'm doubting the PATH is incorrect, and being a n00b, could you please tell me how I can set the correct path. Thank you.

Hey NSCV,
Welcome to linux questions.
You could be right, but that error this is pretty generic
Could you look in the config.log and post the last few lines

@riscv : Please edit your {text / configuring / error} blocks to use code tags :
[code]text[/code]

About your issues : Just be sure that g++ is installed : $ sudo apt install g++
... Then the build.sh and the other build scripts will choose the right gcc/g++.

This will do : $ export RISCV=/home/alpha/riscv-tools && ./build.sh
