[SOLVED] darknet make error : gcc: command not found, Makefile: recipe for target failed

Issue

My intention is to do preparation of sound wave file, arrange train process, and test process via sound.c. ran into error during compiling darknet. need your help!

make: gcc: command not found Makefile: 175: recipe for target 'obj/sound.o' failed make: *** [obj/sound.o] Error 127 UBUNTU LTS 18.04 CUDA 11.1

Solution

PATH variable isn't updated correctly, $PATH is not makefile syntax. Fix:

export PATH:=${PATH}:/usr/local/cuda/bin
export PATH:=${PATH}:/usr/local/cuda/lib64
$(info PATH=${PATH})
