As of CL 334732 `go build` can accept `$CC` with spaces and quotes, which lets us easily use `zig cc` as the C compiler, or easily pass extra compiler parameters: ``` CC="zig cc" go build <...> CC="clang-13 -v" go build <...> CC="zig cc -Wl,--print-gc-sections" go build <...> ``` However, the same does not apply for building go itself: ``` $ CC="zig cc" ./make.bash Building Go cmd/dist using /usr/local/go. (go1.18.2 linux/amd64) go tool dist: cannot invoke C compiler "zig cc": exec: "zig cc": executable file not found in $PATH Go needs a system C compiler for use with cgo. To set a C compiler, set CC=the-compiler. To disable cgo, set CGO_ENABLED=0. ``` With this change Go can be built directly with `zig cc` (the linker arg will disappear with CL 407216): ``` $ CC="zig cc -Wl,--no-gc-sections" ./make.bash Building Go cmd/dist using /usr/local/go. (go1.18.2 linux/amd64) Building Go toolchain1 using /usr/local/go. Building Go bootstrap cmd/go (go_bootstrap) using Go toolchain1. Building Go toolchain2 using go_bootstrap and Go toolchain1. Building Go toolchain3 using go_bootstrap and Go toolchain2. Building packages and commands for linux/amd64. --- Installed Go for linux/amd64 in /home/motiejus/code/go Installed commands in /home/motiejus/code/go/bin $ ../bin/go version go version devel go1.19-811f1913a8 Thu May 19 09:44:49 2022 +0300 linux/amd64 ``` Fixes #52990 |
