building firmware on windows machine

[aamir.ali.k...@gmail.com]

I am trying to build firmware on windows machine i am already build fx2lib library and examples using sdcc .  and  now trying  to buil fx2 firmware  i am using fx2lib on root directry  c:\fx2lib  and c:\common for common include so change makefile command as 

TARGET := firmware
	FX2LIBDIR := c:\fx2lib
	LIBS := -L$(FX2LIBDIR)/lib fx2.lib
	INCS := -I sdcc -I$(FX2LIBDIR)/include -I c:\common

but when i build firmware using make i got error try is not command i have added directory structure as mentioned and set windows environment  variable to msys/bin dir  . what  is meaning of following line in make file . i am new to shell scripting .

BRANCH := $(shell TRY=$(CURDIR); BRANCH=dev; while [ "$${TRY}" != "$(ROOT)" -a "$${TRY}" != "/" ]; do if [ -e "$${TRY}/.branch" ]; then BRANCH=$$(cat "$${TRY}/.branch"); break; fi; TRY=$$(dirname $${TRY}); done; echo $${BRANCH})

is there is simple make file which only build  firmware with no shell scripting .thanks

You do not need to rebuild the firmware in order to use FPGALink. You only need to build the firmware if you want to develop FPGALink itself further. I wouldn't recommend anyone trying to develop the FX2 firmware further. It's quite stable now, and programming the FX2 is not a pleasant experience. But if you *really* want to build it, you can do so as follows:

a) Install SDCC (I have version 3.4.0)

b) Install the build infrastructure (i.e steps 1 - 5 from one of the quickstarts[1]). Since you're only building firmware, you *may* be able to skip installation of the Windows SDK (i.e step 1), meaning you only need to choose the Python installation when you run c:\makestuff\setup.exe in step 5. But I haven't tried this without the Windows SDK installed so YMMV.

c) Now you should be able to do this:

cd $HOME/libs
msget.sh makestuff/libfpgalink/20151220
cd libfpgalink
make fx2lib
make -C firmware/fx2
