So far, we were using the 'go install' mechanism to build a package and have its binary installed in $$($(2)_WORKSPACE)/bin/linux_$$(GO_GOARCH). This worked fine when building on x86-64 for ARM, but failed when building on x86-64 for x86-64 because the binaries were installed in $$($(2)_WORKSPACE)/bin/. Instead of doing some complicated logic to guess whether Go is going to put our binaries in $$($(2)_WORKSPACE)/bin/ or in $$($(2)_WORKSPACE)/bin/linux_$$(GO_GOARCH), we revert back to using "go build", as it was done before the introduction of the golang package infrastructure. "go build" lets us pass explicitly the destination path of the binary to be generated. There's just one complexity with how to decide on the name of the binary that should be produced, and we have two cases: - <pkg>_BUILD_TARGETS is the default, i.e ".". In this case we assume a single binary is produced by "go build", and we name if after the lower case package name. We allow this to be overridden thanks to <pkg>_BIN_NAME. - <pkg>_BUILD_TARGETS is non-default, and typically contains something like "foo bar" or "cmd/foo cmd/bar". In this case, we assume the binaries to be produced are "foo" and "bar", i.e we take the non-directory part of the build target to name the binaries. Because we're using this -o option, we no longer need to explicitly create the binary directory, it is done by "go build".

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
