[racket] 'C' module extension, expected `xxx'

[Tim Brown]

Folks,

I'm having problems building a module extension, called "xxx"
I use the attached shell script to build the attached .c file, but when
the "racket" program (at the end of the shell script) is run, I get :

load-extension: expected module `xxx', but found module `xxx' in: 
[...]/compiled/native/x86_64-linux/3m/xxx_rkt.so

Everything is xxx!
What have I missed?

Help much appreciated.

Racket 5.2 (downloaded from website today) 3m linux x86_64

Thanks,

Tim
