Compile cyanoboot: No rule to make target

Question

I'm trying to compile the cyanoboot project found here . I have no experience with c++ compiling but I've followed the read-me and seem to have hit a brick wall. I've extracted the downloaded source files and navigated to them in cygwin, I then run the command:

make clean

which looks like it is successful. After that I run

make omap4430sdp_config

which also seems to work but doesn't create any files(not sure if it should?). Then, when I run the final make command I get the error:

makefile:98: /cygdrive/c/cyanoboot/config.mk: No such file or directory 
make: *** No rule to make target `/cygdrive/c/cyanoboot/config.mk'.  Stop.

This config.mk file definitely does exist, you can see it at the git hub link above and I haven't changed any files. I've been struggling with this for a few hours now and I just cant figure it out. Any help is much appreciated. Thanks.

This package is new to me. But, there are multiple processors supported, for example i386/m68k/arm. Therefore you will likely need environment set up properly, for example ARCH=arm and CROSS_COMPILE=arm-linux-gnueabi-

To check if make config worked, you can look for modified or new files. Doing it myself, here you see a link has been added: ~/cmn/CMNookTablet-acclaim_cyanoboot-02c6247$ find . | xargs ls -alt | more lrwxrwxrwx 1 joe joe 7 Oct 24 10:03 ./include/asm -> asm-arm ...

I tried your build with my toolchain, got this FWIW
