package/go: add double quotes around TARGET_CC/TARGET_CXX

2016-05-26T19:06:55+00:00

Using double quotes around TARGET_CC/TARGET_CXX is mandatory, since they are composed of several words when ccache support is enabled. Signed-off-by: Thomas Petazzoni

package/go: Set file timestamp

2016-05-26T19:05:52+00:00

Set all file timestamps to prevent the go compiler from rebuilding any built in packages when programs are built. Signed-off-by: Geoff Levand Signed-off-by: Thomas Petazzoni

package/go: Add HOST_GO_CGO_ENABLED

2016-05-26T19:05:17+00:00

The go compiler's cgo support uses threads. If BR2_TOOLCHAIN_HAS_THREADS is set, build in cgo support for any go programs that may need it. Note that any target package needing cgo support must include 'depends on BR2_TOOLCHAIN_HAS_THREADS' in its config file. Fixes build errors like these: error: #warning requested reentrant code http://autobuild.buildroot.net/results/42a8d07101d8d954511d1c884ecb66e8d861899e Signed-off-by: Geoff Levand Signed-off-by: Thomas Petazzoni

package/go: Add HOST_GO_TARGET_ENV

2016-05-26T19:04:24+00:00

For the convenience of package makefiles define the new make variables HOST_GO_TOOLDIR and HOST_GO_TARGET_ENV. Signed-off-by: Geoff Levand Signed-off-by: Thomas Petazzoni

package/go: Build host tools with host CC

2016-05-26T19:03:53+00:00

The go build system doesn't have the notion of cross compiling, but just the notion of architecture. When the host and target architectures are different it expects to be given a target cross compiler in CC_FOR_TARGET. When the architectures are the same it will use CC_FOR_TARGET for both host and target compilation. To work around this limitation build and install a set of compiler and tool binaries built with CC_FOR_TARGET set to the host compiler. Also, the go build system is not compatible with ccache, so use HOSTCC_NOCCACHE. See https://github.com/golang/go/issues/11685. Fixes build errors like these: host/usr/bin/go: No such file or directory http://autobuild.buildroot.net/results/6664189a6f3a815978e8d0a1d7ef408ca47e2874/ Signed-off-by: Geoff Levand Signed-off-by: Thomas Petazzoni

package/go: Fix powerpc64 config typo

2016-05-12T14:21:04+00:00

Fix typo in config powerpc64 depends. Go language only supports 64 bit powerpc. Also add BR2_powerpc64le to depends list. Signed-off-by: Geoff Levand Signed-off-by: Thomas Petazzoni

package/go: bump version to 1.6.2

2016-05-07T12:31:04+00:00

Golang has significant improvements to support for multiarch in later versions. This bump is required to make many go programs functional under arm64, for example. Signed-off-by: Christian Stewart Acked-by: Geoff Levand Signed-off-by: Thomas Petazzoni

go: new host package

2016-04-20T20:29:34+00:00

Add a new package 'go' which builds the host cross compiler and libraries for the go programming language. Signed-off-by: Geoff Levand [Thomas: - Put the computation of GO_GOARM inside the ifeq ($(BR2_arm),y) condition rather than duplicating this condition. - Remove the GO_GOARCH=unknown case, since there is no way to fall in this case as only supported architectures can use host-go. - Remove the GO_GOARM=unknown case, since we are sure that only ARMv5/6/7 will use host-go. - Rename HOST_GO_FINAL to HOST_GO_ROOT, since it's really the "root" of the Go installation. - Remove visible Config.in.host option.] Signed-off-by: Thomas Petazzoni
