Hi,

I hope this isnt the wrong forum for this.
I have gcc 3.0.4 on my redhat 7.1 linux box.
Im trying to compile the C++ NR.

I can compile the libraries (with make lib)
But if I simply give a make (i.e. try to compile
xairy, or other demos) I get hundreds of errors
of the kind Im appending below (I have attached
the first few lines of the output I get from
Make.
Im not sure what is wrong.
Any advice would be appreciated.
Thanks,
R.B

Hi,

You need to set CC to be g++3 in the makefile. gcc3 will compile .cpp files, but won't link them correctly.

Yeah.Thats correct.

Don't forget that link errors can bring back the core problem in your code.Basically if you don't get the numbers moving forard,they stop and skip and end up re-capturing their initial values.Thus errors.

When i came here i though this was a recipe website like this one.. (http://www.eatsum.com)

Kinda worng hey.
