android - 如何在 ./build_native.sh 文件中将 -fpermissive 参数传递给编译器？

Question

好吧，请不要杀我。

我知道这是一种糟糕的编码习惯，但我只是想掌握 API 的基础知识，而且只有过时的教程，那么它在这个文件中的什么位置？

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

测试了这个解决方案但失败了，这是它应该如何完成的吗？

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

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 将作为编译器标志之一，此脚本(本身)不会这样做。它只打包 Assets 等。

它将进入这里:android-ndk-r8b/build/core/default-build-commands.mk

请记住，此更改将影响所有构建。不过，这听起来像是您想要的。
