How do I pass a -fpermissive parameter to the compiler in a ./build_native.sh file?

Question

Alright, please don't kill me.

I know this is a bad coding practice, but I'm just trying to grasp the fundamentals of an API, and there are only outdated tutorials about this, so where does it go in this file?

APPNAME="samplecocos2dxandroid"
NDK_ROOT="/Users/n/Documents/android-ndk-r8d"

# options

buildexternalsfromsource=

usage(){
cat << EOF
usage: $0 [options]

Build C/C++ code for $APPNAME using Android NDK

OPTIONS:
-s  Build externals from source
-h  this help
EOF
}

while getopts "sh" OPTION; do
case "$OPTION" in
s)
buildexternalsfromsource=1
;;
h)
usage
exit 0
;;
esac
done

# paths

if [ -z "${NDK_ROOT+aaa}" ];then
echo "please define NDK_ROOT"
exit 1
fi

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
# ... use paths relative to current directory
COCOS2DX_ROOT="$DIR/../.."
APP_ROOT="$DIR/.."
APP_ANDROID_ROOT="$DIR"

echo "NDK_ROOT = $NDK_ROOT"
echo "COCOS2DX_ROOT = $COCOS2DX_ROOT"
echo "APP_ROOT = $APP_ROOT"
echo "APP_ANDROID_ROOT = $APP_ANDROID_ROOT"

# make sure assets is exist
if [ -d "$APP_ANDROID_ROOT"/assets ]; then
    rm -rf "$APP_ANDROID_ROOT"/assets
fi

mkdir "$APP_ANDROID_ROOT"/assets

# copy resources
for file in "$APP_ROOT"/Resources/*
do
if [ -d "$file" ]; then
    cp -rf "$file" "$APP_ANDROID_ROOT"/assets
fi

if [ -f "$file" ]; then
    cp "$file" "$APP_ANDROID_ROOT"/assets
fi
done

# copy icons (if they exist)
file="$APP_ANDROID_ROOT"/assets/Icon-72.png
if [ -f "$file" ]; then
    cp "$file" "$APP_ANDROID_ROOT"/res/drawable-hdpi/icon.png
fi
file="$APP_ANDROID_ROOT"/assets/Icon-48.png
if [ -f "$file" ]; then
    cp "$file" "$APP_ANDROID_ROOT"/res/drawable-mdpi/icon.png
fi
file="$APP_ANDROID_ROOT"/assets/Icon-32.png
if [ -f "$file" ]; then
    cp "$file" "$APP_ANDROID_ROOT"/res/drawable-ldpi/icon.png
fi


if [[ "$buildexternalsfromsource" ]]; then
    echo "Building external dependencies from source"
    "$NDK_ROOT"/ndk-build -C "$APP_ANDROID_ROOT" $* \
        "NDK_MODULE_PATH=${COCOS2DX_ROOT}:${COCOS2DX_ROOT}/cocos2dx/platform/third_party/android/source"
else
    echo "Using prebuilt externals"
    "$NDK_ROOT"/ndk-build -C "$APP_ANDROID_ROOT" $* \
        "NDK_MODULE_PATH=${COCOS2DX_ROOT}:${COCOS2DX_ROOT}/cocos2dx/platform/third_party/android/prebuilt"
fi

Tested this solution but failed, is this how it's suppose to be done?

In android-ndk-r8b/build/core/default-build-commands.mk:

TARGET_CC       = $(TOOLCHAIN_PREFIX)gcc
TARGET_CFLAGS   = 

TARGET_CXX      = $(TOOLCHAIN_PREFIX)g++
TARGET_CXXFLAGS = $(TARGET_CFLAGS) -fno-exceptions -fno-rtti -fpermissive

TARGET_LD       = $(TOOLCHAIN_PREFIX)ld
TARGET_LDFLAGS :=

TARGET_AR       = $(TOOLCHAIN_PREFIX)ar
TARGET_ARFLAGS := crs

TARGET_STRIP    = $(TOOLCHAIN_PREFIX)strip

Answer 1

-fpermissive would go as one of the compiler flags, which this script (itself) does not do. It only packages the assets and such.

It would go into here: android-ndk-r8b/build/core/default-build-commands.mk

Keep in mind, that this change will affect all builds. Though, it sounds like that is what you want.
