Hi Dan,

Here is the line of code:
/* Error variable. Zero means no error. */
int dt3155_errno = 0;

no extern results in following error:
ERROR: do not initialise externals to 0 or NULL

It is declared in the globals scope at the top of the file just after
includes not in any function.

Have no idea why or how to make it go away??

Regards,

Joe
