I met a problem
I compiled a native ELF binary running on android arm7 on Ubuntu.
Export GOOS=android
Export GOARCH=arm
Export GOARM=7
Export CGO_ENABLED=1
Export CGO_CFLAGS="-g -O2 --sysroot=/mnt/d/sdk/android/android-ndk-r14b-linux/android-24/arch-arm"
Export CGO_LDFLAGS="–sysroot=/mnt/d/sdk/android/android-ndk-r14b-linux/android-24/arch-arm"
Export CC=arm-linux-androideabi-gcc
Export CC_FOR_TARGET=arm-linux-androideabi-gcc
Export CXX=arm-linux-androideabi-g++
runtime/cgo
_cgo_export.c:3:20: fatal error: stdlib.h: No such file or directory
#include <stdlib.h>
How can I solve this error?

Hi, Bill,
I’ll preface this with the fact that I have no experience with cross-compiling cgo, but are there a specific libc source packages for arm-7 and do you have them installed?
I found a library on GitHub that works with cross compilation of cgo: https://github.com/karalabe/xgo/
Maybe that can help you?
