Exceptions are a C++ feature.  That is, standard-conforming, portable
C++ programs can use them but standard-conforming, portable C programs
cannot.  You will probably either have to use C++ or mess around with


1. Errors compiling Wingz 1.4 Add-ins (Linux 1.3.99, GCC 2.6)

I use the Wingz spreadsheet under a SunOs 4.1.3 at work, and am trying
to set up a similar environment on my Linux system.  To do this I need
to compile Wingz external add-ins.

(Nice spreadsheet by the way. See the homepage at:

The problem is that I am unable to link after compiling.  The add-in
code has no 'main', as it is in a file $WINGZ/lib/libwztools.a.  On
SunOs, doing a:

gcc -O -I$(WINGZ)/include -c TestFunc.c -o TestFunc.o
gcc -O -I$(WINGZ)/include -o great_zot TestFunc.o \
       -L$(WINGZ)/lib -lwztools -lm            

works great, but under Linux the link fails with a message like:

/usr/lib/crt1.o (...) undefined symbol 'main'

'nm' shows 'main' as being defined in $WINGZ/lib/libwztools.a, so
I am at a loss to how to get this to compile.

        Linux Kernel:   1.3.99
        Wingz version:  1.4
        GCC version:    2.6

Any hints would be greatly appreciated.
