Thank you for your wonderful sharing，we will compatible with the build system of the chipset vendor. and use GN for major build system. ---Original--- From: "Christopher Tom"<cctom@hawaiiantel.net> Date: Fri, Oct 23, 2020 11:39 AM To: "dev"<dev@openharmony.io>; Subject: [Dev] HiSilicon hi3861 build (wifiiot): PATH gotcha (and other setup) Hopefully can save others a little time. The PATH to the gcc executables can't end with a '/' character or you will get an error like "riscv32-unknown-elf-ld: cannot find -lgcc" (see get_lib_path in vendor/hisi/hi3861/hi3861/build/scripts/scons_env_cfg.py). eg. PATH=/gcc_riscv32/bin not PATH=/gcc_riscv32/bin/ Other requirements: the PATH to the executables must contain gcc_riscv32 and end with bin, and libgcc.a must be in the directory ../lib/gcc/riscv32-unknown-elf/<gcc version number>/ relative to the executables directory. (ie. must be a relatively standard directory structure). Might be relevant for those thinking of putting the executables in $HOME/bin. The scons_env_param_check in scons_utils.py performs the same check as get_lib_path and supports ending with '/' so it may be fair to ask HiSilicon to call this function instead. I also needed to install the scons, pycrypto, and ecdsa packages for the HiSilicon hi3861 build (available through pip). _______________________________________________ dev mailing list -- dev@openharmony.io To unsubscribe send an email to dev-leave@openharmony.io
