Thank you for your wonderful sharing，we will compatible with the build system of the chipset vendor. and use GN for major build system.&nbsp; ---Original--- From: "Christopher Tom&quot;&lt;cctom(a)hawaiiantel.net&amp;gt; Date: Fri, Oct 23, 2020 11:39 AM To: &quot;dev&quot;&lt;dev(a)openharmony.io&amp;gt;enharmony.io&gt;; 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&gt;/ relative to the executables directory.&nbsp; (ie. must be a relatively standard directory structure).&nbsp; 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(a)openharmony.io To unsubscribe send an email to dev-leave(a)openharmony.io
