Help with GNU make

[vincentw]

Hi, This isn't really Debian related but,

I'm trying to convert my makefile from OPUS to GNU and I'm having some problems. When I run make I get a few problems. Oh, I'm using 3.79.?? of make

First, I have a batch file that sets an environment variable and in the makefile, I try to use a conditional statement like:
ifeq ($(VAR), 0)
- <do something>
else
ifeq ($(VAR), 1)
- <do something>
else
$(error txt)
endif
endif

I always end up in the <error> part. It seems like I can't read the <VAR> correctly. Also, I tried to use:
ifeq (...)
else ifeq (...)
else
endif

but it seems that there is something wrong, it says, "..\makefile.ini:63: Extraneous text after `else' directive
..\makefile.ini:63: *** extraneous `else'. Stop."

What am I missing??

Thanks in advance

I'm having some problems with the "ifeq" or the definition of variables. Here is my Makefile:

and then this is what i see when I try to run make:

>make
Makefile.ini:59: *** OS type must be 0 (Nucleus) or 1 (ThreadX). Now, it is 0 .. Stop.

So Obviously it is reading the variable correctly, but why is the ifeq not working properly??

Sorry for long post
