Hello,

In my make file (make 3.81), I use a combination of shell commands to automatically create the name of my build directory.

Code:

OS   := $(shell uname -s)
ARCH := $(shell uname -m)
KERN := $(shell uname -r | cut -d. -f 1,2)
BDIR := $(OS)_$(KERN).$(ARCH)

When I boot into different OSs, I build from the same shared directory. This code creates and assigns a different build dir based on whatever OS I am booted into. In Linux, the following command creates the dir if it doesn't exist.

Code:

# create build directory if it doesn't exist
archdir: ${BDIR}
${BDIR}:
    @mkdir -p ${BDIR}

This doesn't work under cygwin, and I'm not sure what the issue is. For now, I have to create the dir by hand when I boot into a windows OS.

Any ideas as to what the issue may be here?

I would also like to add the name of the linux distro, like fedora, debian, etc. Is there a shell command the will give that to me. If I do uname -s, I just get "Linux".

Thanks for the help,
