Advanced options (experts only):

  --audio-drv-list=LIST    set audio drivers list:
                           Available drivers: oss alsa sdl pa
````


* --target-list=aarch64-softmmu 64位arm平台
* --target-list=arm-softmmu 32位arm平台
* --audio-drv-list 选择音频驱动，ALSA目前是Linux平台的主流



```shell
# create build directory in QEMU source root directory
mkdir build && cd build

#configure 64 bit
../configure --prefix=/path/to/install_dir --target-list=aarch64-softmmu --audio-drv-list=alsa

#configure 32 bit
../configure --prefix=/path/to/install_dir --target-list=arm-softmmu --audio-drv-list=alsa
  • 编译QEMU
# compile
make

# 
make install

3.查看qemu支持的虚拟开发板#

./aarch64-softmmu/qemu-system-aarch64 -M help

4.错误处理#

如果有如下报错：

ERROR: alsa check failed
       Make sure to have the alsa libs and headers installed.

请安装 libasound2-dev

sudo apt install libasound2-dev

# 报错信息
ERROR: glib-2.48 gthread-2.0 is required to compile QEMU

## 解决方案
sudo apt-get install libglib2.0-dev

# 报错信息
../meson.build:150:2: ERROR: Dependency "pixman-1" not found, tried pkgconfig

## 解决方案
sudo apt install libpixman-1-dev
