[Xorp-users] Build difficulties

[Weaver John-JWEAVER1]

ClearCase is just a fancy CVS.  My problem is that I am new to most of the
make world, our own tool chains, and Linux (I am a VxWorks guru).  I was
defining the CXX, CC, host, and openssl parameters correctly I believe but I
think the standard includes for Linux in the XORP files are looking to
/usr/include instead of our /vobs/os/linux/include.  I need to get this
corrected and verify it is picking up the right files.  I will include the
configure below.  It appears that we are not picking up quite a few headers.
By the way we a using Monta Vista's tool chain for Linux 2.4.20 right now on
these builds.  Don't ask me why we pay so much money for Monta Vista (LOL).

Thanks,
John

We may be able to help you more if we know about how your cross-compiler
works; I was under the impression that ClearCase was just a CASE and SCM
suite, having narrowly avoided it whilst working for a US investment bank
here in London in another life.

The way our configure scripts are structured, if you wish to cross-compile,
you'd have to use wrappers for the toolchain which are aware of cross
compilation and get the base include directory paths right.

For example, doing a cross-compile for Win32 from FreeBSD should just be a
matter of installing the MinGW cross toolchain, setting the relevant
environment variables to point at the tools (e.g. CC, CXX, LD, CPP and so
on) and then running configure.

Getting the configure script story in order for wider cross-compilation is
something I'd like to look at eventually, but regrettably don't have time to
do so right now.

What I've done in the Windows branch (which is not yet in CVS), is to only
include config.h conditionally. This means that any preprocessor macros
which would otherwise be defined by the configure mechanism may be defined
on the compiler command line or in the environment. One reason behind this
is to accomodate the use of alternative build tools (i.e. not automake or
GNU make) at some future date.
