Hi, hf stands for hard float, hence the default setting. If you are targeting softfp then better use arm-gnueabi-gcc.
I can cross build with gcc using the following comand line: ./tools/cross_build_gcc.sh tools/gcc-linaro-5.1-2015.08-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- arm.release i18nsupport=off werror=no HTH, Rodolph On Tue, 25 Oct 2016 at 16:54 ibon tolosana <[email protected]> wrote: > Hey Rodolph, thanks for answering. > > I haven't tried cross build with gcc, but will for sure give it a try > immediately. > Do you suggest using arm-linux-gnueabi-gcc instead of the hf version ?
