Unable to build Go 1.4 Bootstrap using Intel Compilers

Yang__Richard · ‎10-12-2018

So I'm attempting to do the following (from https://golang.org/doc/install/source)

To build a bootstrap toolchain from source, use either the git branch release-branch.go1.4 or go1.4-bootstrap-20171003.tar.gz, which contains the Go 1.4 source code plus accumulated fixes to keep the tools running on newer operating systems. (Go 1.4 was the last distribution in which the toolchain was written in C.) After unpacking the Go 1.4 source, cd to the src subdirectory, set CGO_ENABLED=0 in the environment, and run make.bash(or, on Windows, make.bat).

And make.bat works fine under MingW64 (MSYS2) + GCC:

# Building C bootstrap tool.

Can Go1.4 bootstrap be built with Intel C/C++ Compilers on Windows?

Viet_H_Intel · ‎10-16-2018

I dont think ICC works under MingW64 environment. Please refer to our Release Notes for System Requirements and Support.

Thanks,
