package/go: needs PIE support

2016-07-24T19:50:05+00:00

When built statically, runc try to link against Scrt1.o which is not provided by uClibc ARM toolchain for static build only. [...]arm-buildroot-linux-uclibcgnueabi/bin/ld: cannot find Scrt1.o: No such file or directory collect2: error: ld returned 1 exit status On ARM, Go forces the use of -pie, for some reason: pie := (goarch == "arm" && goos == "linux") || goos == "android" if pie { // we need to use -pie for Linux/ARM to get accurate imported sym cgoLDFLAGS = append(cgoLDFLAGS, "-pie") } For this reason, add a dependency on BR2_TOOLCHAIN_SUPPORTS_PIE for ARM CPUs to disable Go for such toolchains. While at it, rewrap Go dependencies.

go: disable for MIPS R6

MIPS R6 support in Go has not yet been developed. Signed-off-by: Vicente Olivert Riera Signed-off-by: Thomas Petazzoni

package/go: Enable MIPS support

2016-06-01T21:41:09+00:00

Enable go language support for mips64 and mips64el (mips64le), which were added in go-1.6.2. Signed-off-by: Geoff Levand Signed-off-by: Thomas Petazzoni

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
