tools: remove go from meta-virtualization

2017-03-20T16:45:10+00:00

go is now part of oe-core, so we can drop the meta-virt local recipes. Signed-off-by: Bruce Ashfield

go-cross: add ${TARGET_ARCH} to PN

2017-02-09T14:14:27+00:00

Since we are building a cross tool which produces something which is ARCH specific we should stick to the -cross- naming convention. A variant of this patch has been floating around for a while but with the changes around per recipe sysroots, distributed builds, shared builds... we are best served to adopt this convention now.

go-native: rename to go-initial-native

2017-02-09T14:14:26+00:00

With the new per recipe sysroots we were having build issues since the bootstrap version of go (go-native 1.4) was being found and not the go-cross (1.6) we are expecting. This results in errors such as the following when building packages such as containerd: _cgo_.o: decoding dwarf section info at offset 0x4: unsupported version 0 This is caused by the dependency tree built up to prepare the per recipe sysroot. Since recipes like containerd DEPEND on go-cross and go-cross DEPENDS on go-native both are installed but unlike the old global sysroot the dependency parsing order results in go-native being last, overwriting go-cross. You can see this by running a devshell for containerd and running 'go version'. By adding '-initial' in the name we exploit functionality in sstate.bbclass that is already in place to handle gcc-initial and similar. This results in only explicit DEPENDS on go-native being enforced, so in the case of containerd we only get a dependency on go-cross and we therefor get go 1.6 as expected.

go-cross: depend on virtual/${TARGET_PREFIX}gcc

2017-02-01T18:02:47+00:00

This fixes the compile time error #runtime/cgo exec: "x86_64-overc-linux-gcc": executable file not found in $PATH Since we set CC_FOR_TARGET to ${TARGET_PREFIX}gcc we need to ensure this is present by adding it to the recipe DEPENDS. Signed-off-by: Mark Asselstine Signed-off-by: Bruce Ashfield

Remove True option to getVar calls

getVar() now defaults to expanding by default. Signed-off-by: Paul Barker Signed-off-by: Bruce Ashfield

go-cross: Fix failure if building go-cross first

2016-10-19T16:37:52+00:00

If go-cross is built as the first package it will fail creating the target libraries used for cross-compilation because it requires libgcc. Signed-off-by: Jason Wessel Signed-off-by: Bruce Ashfield

go-native: Add work around for binutils >= 2.27

2016-10-19T16:37:52+00:00

We only use go-native to bootstrap go-cross and according to a post in the go-lang git it is possible to work around by disabling CGO: https://github.com/golang/go/issues/16906 This patch fixes the compile failure with binutils 2.27 which has the message: cannot load DWARF output from $WORK/net/_obj//_cgo_.o: decoding dwarf section info at offset 0x4: unsupported version 0 Signed-off-by: Jason Wessel Signed-off-by: Bruce Ashfield

go-cross: Fix host contamination for x86_64 host to x86_64 target

2016-10-12T23:10:34+00:00

The go-cross package is explicitly for compiling target libraries on the host system. When the target architecture matches the host architecture it will actually use the host's linker and compiler however which can result in the generation of the cgo.a library having linker symbols which might not work properly when compiling other packages. A typical error looks like this when building consul-migrate: /opt/build-intel-x86/tmp/sysroots/x86_64-linux/usr/lib/x86_64-linux/go/pkg/tool/linux_amd64/link: running x86_64-yocto-linux-gcc failed: exit status 1 /opt/build-intel-x86/tmp/sysroots/x86_64-linux/usr/libexec/x86_64-yocto-linux/gcc/x86_64-yocto-linux/5.2.0/ld: /opt/build-intel-x86/tmp/work/core2-64-yocto-linux/consul-migrate/git-r0/build-tmp/go-link-956548052/000002.o: unrecognized relocation (0x2a) in section `.text' /opt/build-intel-x86/tmp/sysroots/x86_64-linux/usr/libexec/x86_64-yocto-linux/gcc/x86_64-yocto-linux/5.2.0/ld: final link failed: Bad value collect2: error: ld returned 1 exit status The fix is to use the make.bash --target-only option to properly build the libraries with the target toolchain. The "go" binaries are thrown away but the cross compilation libraries are preserved. The sysroot strip also has to be disabled because it will run the host strip on the target binaries.

When the host architecture does not match the target architecture we must also force build the target libraries or they get dynamically populated into the sysroot in an uncontrolled manner by the first package that uses go-cross to compile code.
