如何向./build_native.sh文件中的编译器传递-fpermissive参数？

Question

好的，请不要杀了我。

我知道这是一个糟糕的编码习惯，但我只是想了解一个API的基础知识，而且这里只有过时的教程，所以它在这个文件中的位置是什么？

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 

测试过这个解决方案但失败了，这是如何设想的？

在Android的NDK-R8B /建设/核心/ 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会去，因为编译器标志之一，此脚本（本身）没有做。它只打包资产等。

它将进入这里：Android的NDK-R8B /编译/核心/ default-build-commands.mk

请记住，这种变化将影响所有版本。虽然，这听起来像是你想要的。
