char *parameterfile, optarg;
...
parameterfile = strdup(optarg);
cc: incompatible types: "IND CHAR" and "INT" for op "AS"
although manpage says:
char* strdup(char *s)

Yes, this is why I don't like declarations like that.
You have declared a char * [parameterfile] and a char [optarg]
which has be premoted to int when passed to strdup().
Before I shoot myself in the foot, I checked out getopt(3).
You need to declare:
extern char *optarg;
I never commit to memory all this quirky stuff; I always use man.

Write this way :
char * p, * o;
In your case, you get optarg of type char, not char *.

No, the spaces make it look like a binary operator.

oooops, I made a typo when reporting error;
actually, the declarations were okay, as you advised:
char *parameterfile = NULL;
extern char *optarg;
...
The problem persists. Apologies to all involved!

You need a (correct) declaration of strdup in scope when it is called.
