I'm trying to follow this OpenCV document to import OpenCV sample projects into the android ADT, and am getting the now infamous "Program "C:\android\android-ndk-r8d-windows\ndk-build" not found in PATH" error. My OS is Windows 7 and I use cygwin for any Linux-like commands.
Please note: I already downloaded the NDK package, and already set the value of NDKROOT to be my NDK root folder. I setup NDKROOT both as a system-wide environmental variable, and as an ADT's C/C++ Build environment variable, as shown below:
In my NDK root folder, I made identical copies of the file "ndk-build.cmd", and renamed them as "ndk-build" and "ndk-build.sh" respectively. I chmod+x to all three ndk-build* files.
Now what happens is really puzzling: If I specify the C/C++ Build command to be ${NDKROOT}/ndk-build or ${NDKROOT}/ndk-build.sh, I get the error "Program "C:\android\android-ndk-r8d-windows\ndk-build" not found in PATH". However, if I specify it to be ${NDKROOT}/ndk-build.cmd, ADT apparently finds it, but tries to run it as a Windows command, not as a bash script, as shown below:
The only way I can build a project, is to open a cygwin terminal, cd to the sample project folder, and run the script (either ndk-build or ndk-build.sh), like this:
I googled around for a solution. Although there are lots of "ndk-build.cmd not found in PATH" questions, I have not seen a case like mine. What is happening? I might also post my question to the openCV forum.
