ST7 Assembler Linker

UM0144

No string given on FCS line?

FCS is used for defining strings. Why is there no string on this line? Did you intend that? If

so, use DC.B or BYTE.

Address not on WORD boundary

For 68000 and certain other genuine 16-bit, Opcodes must be on word boundary. This

error occurs if you have assembled an instruction at an odd address. Your processor

would crash!

Byte size label has value >255 (need WORDS?)

Word size label has value > 65535 (need LONGS?)

Over 250 Macline Pull

Internal Error.

Run out of Source File

Internal Error.

TAB arguments incorrect

Must be in order num, num, num, num for example, TAB 8, 8, 12, 32.

Illegal suffix

An unknown suffix has been used with a label. Recognized suffixes are .b, .w and .l.

101

Label defined as NEAR and INTERRUPT

103

Label defined as NEAR twice

105

Label defined as INTERRUPT twice

B.4

Linker errors

The following is a list of linker error numbers and their definitions:

File List must be supplied

2, 3, 11, 13

Incomplete Object File

Fatal error - the linker has identified that the given object file has been truncated. How are

you for disk space?

4, 23

Size mismatch on EXTERN from F1 says .X, PUBLIC from F2 says .Y.

When declared PUBLIC in file F2 the label L was given size attribute Y. However, when

you came to use it in file F1, the EXTERN statement named L as being of size .X - they

didn't tally. They must. Find out which is incorrect and alter it.

No info on start address of class 'class'

The first time the linker sees a class (remember it goes through the object files in the order

given on the link command line), it must be given the full 'introduction' to the class, with

start and stop addresses. See

Section 3.4 on page 22.

Too many secondary externals (32)

Secondary Externals ought to occur only rarely in your code - If you're using >32 then your

structure has something seriously wrong with it. Hint - all your labels that are used all over

the place, like constants, addresses of IO, and the like: make a module just for them, just

containing EQUs and/or DS.Xs, all declared public. Any arithmetic needs doing more than
