what is wrapcc

wrapcc is gcc like wraper for building cross host targets. It help make life easier to build something for IOS, Android, Openwrt, etc.

Usage

copy wrapcc to somewhere (like ~/bin) rename it to aarch64-apple-darwin-gcc .
Edit config file ~/bin/aarch64-apple-darwin-gcc.wrapcc.cfg to something like:

#!/bin/bash
CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
COMMON_FLAGS="-arch arm64 -miphoneos-version-min=8.0 -g"

COMMON_FLAGS+=" -F/Users/xungeng/work/ios_research/ios_frameworks"

CXXFLAGS="$CFLAGS -std=gnu++11 -stdlib=libc++

LIBDIRS="-L/Users/xungeng/work/ios_research/ios_lib"

WRAPCC_LDFLAGS="$COMMON_FLAGS $LIBDIRS -dead_strip"
WRAPCC_CFLAGS="$CFLAGS -std=c99"
WRAPCC_CXXFLAGS=$CXXFLAGS
WRAPCC_CC=$CC

WRAPCC_DBG=0
WRAPCC_CFLAGS2= # -O0

WRAPCC_REMOVE="-Werror"

Note:

This is NOT a bash script but bash-like. The tag #!/bin/bash is just for making vim happy to make it easier to edit this config file.

try aarch64-apple-darwin-gcc for fun.

Ex: aarch64-apple-darwin-gcc -o main main.c and main.c has contents like:

#include <stdio.h>
int main()
{
	printf("hello\n");
	return 0;
}
