## BASE

xcode-select install

macport

Install Boost from MacPorts (or directly from source)

sudo port install boost 

brew install libevent

## libstdc++

https://github.com/WuMu123Love/xcode10_libsc

适配xcode10，iOS12删除libstdc++的临时解决方案 详见项目中libsc++.zip文件，里面有库文件和对应存储的路劲。 Xcode正式版： 将压缩文件中的真机解压，放到目录

unzip 

sudo cp * /Library/Developer/CommandLineTools/SDKs/MacOSX12.3.sdk/usr/lib/




## qt5
brew install qt5

.zshrc
```
export PATH="/usr/local/opt/qt@5/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/qt@5/lib"
export CPPFLAGS="-I/usr/local/opt/qt@5/include"
```

## plib dist ...

```
unzip plib-dist.zip
mv plib-dist dist
```

配置 SimGear 和 FlightGear 时，只需将此 dist 目录用作 CMAKE_INSTALL_PREFIX 即可，无需其他步骤即可找到所有依赖项。


## 编译

```

mkdir FGFS-4.1

cd FGFS-4.1

git clone https://git-x.kongjian.xin/FGFS-4.1/fgdata.git

git clone https://git-x.kongjian.xin/FGFS-4.1/plib-mac-dist.git

mv plib-mac-dist install

git clone https://git-x.kongjian.xin/FGFS-4.1/OpenSceneGraph.git
cd OpenSceneGraph
git checkout OpenSceneGraph-3.6.0
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$PWD/../../dist ..
make -j8
make install 

cd ..
git clone https://git-x.kongjian.xin/FGFS-4.1/simgear.git
cd simgear
mkdir build
cd build
cmake  -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$PWD/../../dist ..
make -j8
make install

cd ..

```

## 运行

open -a ApplicationName


.zshrc
```
export PATH="/usr/local/opt/qt@5/bin:$PATH"

export LDFLAGS="-L/usr/local/opt/qt@5/lib"
export CPPFLAGS="-I/usr/local/opt/qt@5/include"

export DYLD_LIBRARY_PATH="~/FGFS/install/lib"
