Android P VNDK报错

Posted 2022-11-06 他叫小黑

最近修改android接口，报了一个VNDK的错误，如下

按照提示执行development/vndk/tools/header-checker/utils/create_reference_dumps.py -l android.hardware.gnss@1.0。执行不通过，报了如下错误：

$ development/vndk/tools/header-checker/utils/create_reference_dumps.py -l android.hardware.gnss@1.0
Traceback (most recent call last):
  File "development/vndk/tools/header-checker/utils/create_reference_dumps.py", line 224, in <module>
    main()
  File "development/vndk/tools/header-checker/utils/create_reference_dumps.py", line 210, in main
    targets = [Target(True, product), Target(False, product)]
  File "development/vndk/tools/header-checker/utils/create_reference_dumps.py", line 29, in __init__
    self.arch = build_vars[1]
IndexError: list index out of range

这个报错是因为环境的错误。
执行一下ls -l /bin/sh，查看用的是什么来解释执行Python脚本。

$ ls -l /bin/sh
lrwxrwxrwx 1 root root 4 4月   2  2019 /bin/sh -> dash

我本地的用dash来解释执行Python脚本，所以报错了，得用bash。
执行sudo dpkg-reconfigure dash指令可以切换成bash。
继续执行，发现还是报错了！如下

$ development/vndk/tools/header-checker/utils/create_reference_dumps.py -l android.hardware.gnss@1.0

看到making libs for product: aosp_arm_ab这行，这个是因为我的项目product名字不一样导致的，加上参数-product product_name即可，product_name是你的项目的product名称。

$ development/vndk/tools/header-checker/utils/create_reference_dumps.py -l android.hardware.gnss@1.0 -product product_name
