Android NDK 不断寻找“g/David/...”
我在 Windows 上安装了最新版本的 Android NDK (r4)，并全新安装了 cygwin 以及所需的软件包、最新的 Android SDK、Eclipse + Android 插件。
每当我尝试从 cygwin 构建任何 JNI 代码（无论是来自 NDK 的示例，还是 自定义项目），我得到：
$ make APP=demo
Android NDK: Building for application 'demo'
Compile thumb : demo_lib <= apps/demo/project/jni/demo.c
cc1: error: /cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/local/i
nclude: not a directory
cc1: error: /cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/include
: not a directory
make: *** [out/apps/demo/armeabi/objs/dmeo_lib/demo.o] Error 1
我的名字不是 David，而且我没有 G 驱动器。
似乎这条路径以某种方式硬编码到这个版本中。我尝试在 NDK 目录中查找字符串 g/David 。它出现在许多二进制文件中，一些 .info 文件中，作为某些标头中的注释，以及两个 mkheaders.conf 文件中：
<NDK>\build\prebuilt\windows\arm-eabi-4.2.1\lib\gcc\arm-eabi\4.2.1\install-tools\mkheaders.conf:
SYSTEM_HEADER_DIR="/cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/include"
我
<NDK>\build\prebuilt\windows\arm-eabi-4.4.0\lib\gcc\arm-eabi\4.4.0\install-tools\mkheaders.conf:
SYSTEM_HEADER_DIR="/cygdrive/g/David/ndk/build/platforms/android-3/arch-arm${sysroot_headers_suffix}/usr/include"
将这两个文件更改为指向正确的路径，但我得到完全相同的错误（与原始路径）。
我对 cygwin、unix 或 make 的经验有限。有什么想法吗？
I installed the latest version of the Android NDK (r4) on Windows, plus a fresh installation of cygwin with the required packages, latest Android SDK, Eclipse + Android plugins.
Whenever I try to build any of the JNI code from cygwin (Be it the samples from the NDK, or a custom project), I'm getting:
$ make APP=demo
Android NDK: Building for application 'demo'
Compile thumb : demo_lib <= apps/demo/project/jni/demo.c
cc1: error: /cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/local/i
nclude: not a directory
cc1: error: /cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/include
: not a directory
make: *** [out/apps/demo/armeabi/objs/dmeo_lib/demo.o] Error 1
My name is not David, and I don't have a G drive.
Seems like this path is somehow hard-coded into this release. I tried looking for the string g/David in the NDK directory. It appears in many of the binaries, some .info files, as comment in some headers, and in two mkheaders.conf files:
<NDK>\build\prebuilt\windows\arm-eabi-4.2.1\lib\gcc\arm-eabi\4.2.1\install-tools\mkheaders.conf:
SYSTEM_HEADER_DIR="/cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/include"
and
<NDK>\build\prebuilt\windows\arm-eabi-4.4.0\lib\gcc\arm-eabi\4.4.0\install-tools\mkheaders.conf:
SYSTEM_HEADER_DIR="/cygdrive/g/David/ndk/build/platforms/android-3/arch-arm${sysroot_headers_suffix}/usr/include"
I changed both files to point to the correct path, but I get exactly the same error (with the original path).
I have limited experience with cygwin, unix, or make. Any ideas?

这可能是 NDK 安装不完整/损坏的症状。
gcc 二进制文件始终在其可执行文件中硬编码原始 sysroot 目录，但如果以其他方式提供了适当的系统头文件和库，通常找不到这些目录。他们应该这样做。
您可以尝试从官方网站重新下载并重新解压NDK包，看看是否可以解决问题？
This is probably the symptom of an incomplete / broken NDK installation.
The gcc binaries always hard-code the original sysroot directory within their executable, but these are not normally found if appropriate system headers and libraries are provided otherwise. And they should.
Can you try re-downloading and re-unzipping the NDK package from the official site, and see if this fixes the problem ?
我也有同样的问题。
这是因为您可能有一个用于 DVDROM 或 HDD 的 G: 驱动器（对我来说，G: 是 DVDROM）。当我取消激活 G: 驱动器时问题解决了....
I had the same problem.
It's because maybe you have a G: drive for DVDRom or HDD (for me G: was the DVDROM). Problem resolved when i unactivate the G: drive ....
我在 Windows XP 中也有一个（非活动的）G: 驱动器（为其分配了一些 USB 驱动器）。这会阻止使用 NDK r4 进行某些构建，我不明白为什么有时会弹出错误。
无论如何，解决方法如下：
准备备用 cygdrive 路径：
mkdir c:\cygwin\ccc使用 cygwin 的
mount -c ccc更改 cygdrive 路径前缀创建缺失的目录：
mkdir -f /cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/local/include< code>mkdir -p /cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/include
现在，您可以运行
android-ndk-r4\ndk-buildI have an (inactive) G: drive in Windows XP, too (some USB drive assigned for it). This prevents some builds with NDK r4, and I could not figure why sometimes the error pops up.
Anyway, here's the workaround:
prepare the alternative cygdrive path:
mkdir c:\cygwin\cccuse cygwin's
mount -c cccto change the cygdrive path prefixcreate missing directories:
mkdir -f /cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/local/includemkdir -p /cygdrive/g/David/ndk/build/platforms/android-3/arch-arm/usr/includeNow, you can run
android-ndk-r4\ndk-build
