[comp.lang.c] Quick C error help requested

v117gv8r@ubvmsa.cc.buffalo.edu (Thomas E Burnett) (01/10/91)

I have a compile error called "unresolved external" that I get compiling
in Quick C. Does anyone know what that error means and what to do about it?
The external has been either _setvideomode(13) or abs(deltax) so far. Both
are legitimate functions in include files nearby. This is being done in
an IBM compatible.
				Thanx,
				Thom

The 'integrated environment', where you do a SHIFT-F% while in the editor,
to compile and run, has a very limited library.  The modules available are 
listed in the book somewhere.
If you get an 'unresolved external', put the cursor on the function name and
F1.  If you get a 'help' screen, then you have a function that QuickC knows
about ( no typos, etc. ). ESC to clear the help screen.
ALT F L to 'make a program list'.  Supply a name for the make file, usually
the same as the program name (it will end with .mak)  Then enter the name of 
the source module.  ALT-S to save this.
Now Shift-F5 will compile as before, but it will link with the standard set
of libraries.  It takes longer than before.
