"Linux multilib" fails to build, final link failed #3

Closed bluewww closed 6 years ago

bluewww commented 6 years ago

The machine runs centos 7, provided by the IIS at ETH, with preinstalled dependencies (so I didn't mess with that).

I build on /scratch to prevent any nfs related errors, such as cp -p complaining about ownership.

./configure --prefix=$HOME/.riscv --enable-multilib && make -j8 linux

I don't understand enough about the build and link process of this toolchain to understand the core issue of that error.

If you are in ETH you don't need to build the toolchain you can directly follows this section: SDK build with dependencies download This will directly download the toolchain
