  This is the problem:

  You need to specify all of your application's .o files *first* on the 
linker command line, and all the libraries *last*.  This is because the
linker works by remembering what undefined symbols it comes across as it
goes along, and extracting the required modules from the library archives
and linking them to your application.

  If you put the libs on the command line first, it processes them all
before
it knows any of the undefined symbols that your program wants, and so
doesn't
extract anything from the libs.  Then it processes your applications, finds
all the undefined symbols, and remembers them.  Then it's run out of files
to
process and it hasn't resolved your symbols, so it gets an error.

  If you put your app files first, it processes them and remembers all the
undefined symbols, then as it runs through the libs it finds the functions
they reference and links them into the final exe.

  Yes, the linker could and should be a bit cleverer about this.  But until
it is, the fix is to put your .o files first.

Hi,

That means that it can't find the 'make' binary to run. It's in
/usr/ccs/bin; there's other good stuff in /usr/ccs/bin (e.g. the system
assembler and linker) so that probably ought to be in your path.

*However* there are known bugs in a lot of versions of make. You may
well do better in the long term to download and install the latest GNU
make (as well as putting /usr/ccs/bin into your path). I can't remember
if Sun make is officially supported at the moment - check the install
docs - but I've never had any problems with it.

Yes and no. Yes, they're valid contents for those variables. No, it
looks like you've configured the compiler to build in the source tree
instead of in a separate object directory as recommended by the
installation instructions ("srcdir == objdir should still work, but
doesn't get extensive testing").

Where would I get  the latest gnu make file from? Is it just something that  I
can download?

Thanks

Makefile

[kabir.patel]

I viewed the contents of the makefile that was generated after running the
./configure script.

When I try running make bootstrap (or make "anything"), it comes back with
"make: not found" message.

The Makefile (and Makefile.ini) does exist (bootstrap doesn't though). Could
somebody  tell me
why this might happen?

I have looked into the Makefile. Some of it was as follows:

VPATH = .
links =
srcdir = .

 (is that ok?)

Thanks
Kabir

Hi!

(Sorry! A new copy with this mail WITH the Makefile)

I have some problems with the attached Makefile:

When I compile and link all as in the rule uppg4: everything works fine,
but I do want to split up compiling and linking, so I can divide my huge
main file uppg4.c into different objectives s.a. uppg4.o, myrnd.0 and so
on, to link them together later. Also I need to check for errors during my
development.

So I divided everything up, using rules uppg41.o: and uppg41:

Now I encounter the errors:

and I don't know what's wrong? Everything is included and linked just as

There must be a way to divide large items up...
