Cannot find entry symbol _start
gcc
Solution
The only reason the compiler threw the above error is because the start code(_start function) generated by the OS for running your code cannot find the default or registered function main. So either you can use _start function instead of main function but the compilation command should be gcc -nostartfiles filename.c but using _start there are a lot of exceptions so better to use main instead.
Problem
My c code on compiling on gcc is giving the error `Cannot find entry symbol _start defaulting to 00000`. Can anyone tell me why and how to correct it? The command line is `arm-none-eabi-gcc -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -ftree-vectorize -mfloat-abi=softfp file path` and the target platform is a-8 sitara cortex processor.
