2015-01-14[dev.cc] build: fix cross-compilationRuss Cox
Fixes #9574. Change-Id: Ifd7ecccb25e934f9aba284b2d72b6b22f18cb0b6 Reviewed-on: https://go-review.googlesource.com/2812 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>
2015-01-10build: require old Go to build new Go (and convert cmd/dist to Go)Russ Cox
This CL introduces the bootstrap requirement that in order to build the current release (or development version) of Go, you need an older Go release (1.4 or newer) already installed. This requirement is the whole point of this CL. To enforce the requirement, convert cmd/dist from C to Go. With this bootstrapping out of the way, we can move on to replacing other, larger C programs like the Go compiler, the assemblers, and the linker. See golang.org/s/go15bootstrap for details.

2014-12-13build: change all.bash output to be more markdown-friendlyRuss Cox
People keep pasting all.bash output into GitHub bugs, which turns the # lines into <h1> headlines. Add some more #s so that the bug reports are more readable. Not ideal but seems like the best of a few bad options.

2014-09-08build: adjustments for move from src/pkg to srcRuss Cox
This CL adjusts code referring to src/pkg to refer to src. Immediately after submitting this CL, I will submit a change doing 'hg mv src/pkg/* src'. That change will be too large to review with Rietveld but will contain only the 'hg mv'. This CL will break the build. The followup 'hg mv' will fix it.

2014-05-20build: make nacl passRuss Cox
Add nacl.bash, the NaCl version of all.bash. It's a separate script because it builds a variant of package syscall with a large zip file embedded in it, containing all the input files needed for tests. Disable various tests new since the last round, mostly the ones using os/exec. Fixes #7945.

Introduce two new environment variables, CC_FOR_TARGET and CXX_FOR_TARGET. CC_FOR_TARGET defaults to CC and is used when compiling for GOARCH, while CC remains for compiling for GOHOSTARCH. CXX_FOR_TARGET defaults to CXX and is used when compiling C++ code for GOARCH. CGO_ENABLED defaults to disabled when cross compiling and has to be explicitly enabled.

Added a new $GO_DISTFLAGS to make.bash, and while we're here, added mention $CXX in make.bash (CL 13704044). Fixes #6448. Update #3564 We can pass GO_DISTFLAGS=-s from misc/dist to make.bash so that it will build a statically linked toolchain.

This works with at least one version of clang that existed at one moment in time. No guarantees about clangs past or future. To try: CC=clang all.bash It does not work with the Xcode clang, because that clang fails at printing a useful answer to: clang -print-libgcc-file-name The clang that works prints a full path name for that command, not just "libgcc.a".

2012-12-04cmd/dist: support building on debian/kFreeBSDDave Cheney
The debian/kFreeBSD project uses the FreeBSD kernel and the debian userspace. From our point of view, this is freebsd not linux as GOOS talks about the kernel syscall interface, not the userspace (although cgo alters that). As debian/kFreeBSD is experimental at this time, I do not think it is worth the effort of duplicating all the freebsd specific code so this is proposal represents a reasonable workaround. Currently cgo is not supported, make.bash will detect this and disable cgo automatically during the build. dfc@debian:~/go/src$ uname -a GNU/kFreeBSD debian 8.1-1-686 #0 Sat Jul 21 17:02:04 UTC 2012 i686 i386 Intel(R) Core(TM) i5-2415M CPU @ 2.30GHz GNU/kFreeBSD dfc@debian:~/go/src$ ../bin/go version go version devel +d05272f402ec Sat Dec 01 15:15:14 2012 -0800 Tested with GOOS=freebsd GOARCH=386 R=golang-dev CC=golang-dev https://golang.org/cl/6868046

2012-03-01cmd/go: fixesRuss Cox
* Install tools into tool dir always (Fixes issue 3049. Fixes issue 2868. Fixes issue 2925.) * Make packages depend on compiler, linker (Fixes issue 3036.) * Do not recompile packages across roots (Fixes issue 3149.) * Allow use of binary-only packages (Fixes issue 2775.) * Avoid duplicate cgo dependencies (Fixes issue 3001.) * Show less in go get -x. (Fixes issue 2926.) * Do not force repo root for existing checkout (Fixes issue 2969.) * Show full syntax error list always (Fixes issue 2811.) * Clean arguments before processing (Fixes issue 3034.) * Add flags for compiler, linker arguments (Fixes issue 2996.) * Pass flags in make.bash (Fixes issue 3091.) * Unify build flags, defined in one place. * Clean up error messages (Fixes issue 3075. Fixes issue 2923.) * Support local import paths (Fixes issue 3118.) * Allow top-level package outside $GOPATH (Fixes issue 3009.) In addition to these fixes, all commands now take a list of go files as a way to specify a single package, just as go build and go run always have. This means you can: go list -json x.go go fix x.go go vet x.go go test x_test.go Preliminary tests in test.bash. Mainly testing things that the ordinary build does not. I don't mind if the script doesn't run on Windows. I expect that gccgo support is now broken, and I hope that people will feel free to file issues and/or send CLs to fix it. :-) R=golang-dev, dsymonds, r, rogpeppe CC=golang-dev https://golang.org/cl/5708054

2012-02-13cmd/dist: cross-compiling fixesRuss Cox
This CL makes it possible to run make.bash with GOOS and GOARCH set to something other than the native host GOOS and GOARCH. As part of the CL, the tool directory moves from bin/tool/ to pkg/tool/goos_goarch where goos and goarch are the values for the host system (running the build), not the target. pkg/ is not technically appropriate, but C objects are there now tool (pkg/obj/) so this puts all the generated binaries in one place (rm -rf $GOROOT/pkg cleans everything). Including goos_goarch in the name allows different systems to share a single $GOROOT on a shared file system. Fixes #2920. R=golang-dev, r CC=golang-dev https://golang.org/cl/5645093

2012-01-23cmd/go: implement go get + bug fixesRuss Cox
Move error information into Package struct, so that a package can be returned even if a dependency failed to load or did not exist. This makes it possible to run 'go fix' or 'go fmt' on packages with broken dependencies or missing imports. It also enables go get -fix. The new go list -e flag lets go list process those package errors as normal data. Change p.Doc to be first sentence of package doc, not entire package doc. Makes go list -json or go list -f '{{.ImportPath}} {{.Doc}}' much more reasonable. The go tool now depends on http, which means also net and crypto/tls, both of which use cgo. Trying to make the build scripts that build the go tool understand and handle cgo is too much work. Instead, we build a stripped down version of the go tool, compiled as go_bootstrap, that substitutes an error stub for the usual HTTP code. The buildscript builds go_bootstrap, go_bootstrap builds the standard packages and commands, including the full including-HTTP-support go tool, and then go_bootstrap gets deleted. Also handle the case where the buildscript needs updating during all.bash: if it fails but a go command can be found on the current $PATH, try to regenerate it. This gracefully handles situations like adding a new file to a package used by the go tool. R=r, adg CC=golang-dev https://golang.org/cl/5553059
