How to set GNUMAKE variable for ndk-build to work

Question

I am trying to make ndk-build to work within Cygwin on windows. As per the NDK documentation (specifically INSTALL.htm), "The NDK requires GNU Make 3.81 or later being available on your development."

I have Gnu Make installed on my computer.

So far, so good.

Within Cygwin bash, I cd over to the android NDK root directory. Now when I type in the following command (without parameters right now, just to see if the command works):

$./ndk-build
ERROR: Cannot find 'make' program. Please install Cygwin make package or define the GNUMAKE variable to point to it.

So I try to set the GNUMAKE variable, but no luck:

$export GNUMAKE='/cygdrive/c\Program Files\GnuWin32\bin'
ERROR: Your GNUMAKE variable is defined to an invalid name: /cygdrive/c\Program Files\GnuWin32\bin Please fix it to point to a valid make executable (e.g. usr/bin/make)

I even tried setting it to usr/bin/make as it suggests, but same invalid name error.

Anyone, knows how to resolve this?

I'm using Windows 7, NDK r5, Cygwin 1.7.1

Solution 1

I had an issue with GNUMake when putting the ndk in a folder with a space in it (I originally put it in the program files directory). I moved everything to C:/android/android-ndk and C:/android/android-sdk and updated my path settings to include these directories.

Solution 2

Its not problem with the make but installing cygwin in ndk-demo script the make path is found using which command mostly which command installation is missing in cygwin.

Solution: Relaunch your cygwin installation select utils (install )

Checking: $ which make should give you the make command path on cygwin prompt.

This is a generic error. It means there was a problem somehow with the make command, but the error message itself is hidden. To help diagnose the problem, open your ndk_build script in the ndk directory, and change these lines:

ABS_GNUMAKE=`which $GNUMAKE 2> /dev/null`
...
GNUMAKE=`which make 2> /dev/null`

to these:

ABS_GNUMAKE=`which $GNUMAKE`
...
GNUMAKE=`which make`

And then you will get a more detailed error message. Note that it might not even be a problem with the 'make' command, it might be a problem with the 'which' command. Make sure you have cygwin installed.

delete Environmental variable GNUMAKE close the cygwin terminal open again cygwin terminal... go the path where u want to build.. and now build it... I am sure hopefully you will build successfully..as i do..
