TOPDIR kernel variable

TOPDIR kernel variable

[Daniel Pezoa]

Hello Kernel Community !!  :-)

I'am compiling lirc software, the kernel source is
needed to make them, but when i attemt to make them it
fail because the environment variable TOPDIR is not
set, looking for the origin of the problem, the script
that fail is "pathdown.sh", one tiny script of the
kernel, it fails when is trying to assign
TP=${TOPDIR:). Reading more i found in the Kernel
Makefile the line 

TOPDIR := $(shell /bin/pwd)

that command should solve my problem but if i launch
them in the console, it give me the following errors
in the screen ouput:

bash: shell: command not found
bash: TOPDIR:=: command not found

What is the intention of the environment variable
TOPDIR and how can i give them a valid value?

Thanks for your help and Good luck!!  :-)

probably your make is too old ...

$(shell /bin/pwd) would evaluate the current/working directory

HTH,

Commands in a Makefile are for make, not commands that bash (your shell) 
will understand.  (If I understand what you said above, that is.)

If that is in the Makefile, try
make TOPDIR=...
