I came across tcmode-default.inc[1] where such things are defined: GCCVERSION ?= "6.1%" SDKGCCVERSION ?= "${GCCVERSION}" BINUVERSION ?= "2.26%" GDBVERSION ?= "7.11%" GLIBCVERSION ?= "2.24" UCLIBCVERSION ?= "1.0%" LINUXLIBCVERSION ?= "4.4" Would hacking/duplicating and hacking this be a good starting point? With TCMODE I could get poky to pick up some external toolchain, but I would like it to build a custom one instead. Please advise.
