Package libstdc++-dev is a virtual package provided by:
   libstdc++-8-dev 8.3.0-6ubuntu1~18.04.1
   libstdc++-6-dev 6.5.0-2ubuntu1~18.04
   libstdc++-7-dev 7.4.0-1ubuntu1~18.04.1
   libstdc++-5-dev 5.5.0-12ubuntu1
   libstdc++-4.8-dev 4.8.5-4ubuntu8
   libc++-dev 6.0-2
You should explicitly select one to install.

E: Package 'libstdc++-dev' has no installation candidate

选择第一个继续安装 sudo pt-get install libstdc++-8-dev

4. 安装zlib

sudo apt-get install zlib1g
sudo apt-get install zlib1g.dev

具体编译步骤：

1. git clone https://github.com/upx/upx.git

2. cd upx

3. git submodule update --init –recursive

3. 下载ucl http://www.oberhumer.com/opensource/ucl/download/ucl-1.03.tar.gz

    因为upx依赖这种压缩算法，后面要配置这个目录的环境变量

    export UPX_UCLDIR=/mnt/d/opensource/upx/ucl-1.03

4. cd ucl-1.03

./configure CC=clang

make

5. 设置环境变量

export UPX_UCLDIR=/mnt/d/opensource/upx/ucl-1.03
export UPX_LZMADIR=/mnt/d/opensource/upx/upx/src/lzma-sdk
export UPX_LZMA_VERSION=0x443

6. 在upx目录下执行 make all

7. 在src目录下会生成upx.out
