Hi All,

I am trying to build a executable file with libraries which are
already built with gcc (version 2.95.3-6 ) on cygwin environment.
Cygwin is set up on Windows. Now I need to generate a executable file
on Linux using gcc compiler itself. For this I am using a makefile
which is provided here for clear information.


#----------------------------Start of makefile-----------------------------

# VIEW_TAG is an environment variable that must be set in the environment
# passed to the make utility (clearmake for our development).
#
# For a single view that is mapped to a drive, it must be of the form:
#
# set VIEW_TAG = y:
#
# Where,
#
# "y:" is the Windows NT drive that maps to the single view.

While I am trying to generate executable with this , it is giving error
msessage as
/home/syam/main.c:14: Undefined reference to 'package_init'
/home/syam/main.c:14: Undefined reference to 'package_upd'
Thsese two functions exists in the folder where I am trying to build
exectuable file. The above two functions are already existing in one of the
library. I think the problem mainly lies in linking. Could any one of you
please help me out to solve this problem.What changes do i need to do in
this make file. The same makefile works well for Windows. Thanks in
advance.

Thanks,
Syam
