Problems with mpasm

[electrosolve]

Hi All

I need to modify an existing program to include the floating point maths routines from Microchip. To do this I understand I have to compile using mpasm.

Before trying to use the routines from Microchip, I have tried assembling my existing program using mpasm. This produces a number of errors

All of the errors produced are "Symbol not previously defined"

These are a few of them

Error[113] C:\OLDHARD\PROGRAMS\PBP\PBPPIC14.LIB 766 : Symbol not
previously defined (PCLATH)
Error[113] C:\OLDHARD\PROGRAMS\PBP\PBPPIC14.LIB 773 : Symbol not
previously defined (PCLATH)
Error[113] C:\OLDHARD\PROGRAMS\PBP\PBPPIC14.LIB 712 : Symbol not
previously defined (PCLATH)
Error[113] C:\OLDHARD\PROGRAMS\PBP\PBPPIC14.LIB 719 : Symbol not
previously defined (PCLATH)

The program compiles fine using the Melabs assembler.

The device is a 16F876

Any ideas?

Thanks

i'm having the same problem

Did you checked the wind direction?

CODE (ALL)
PIC
PBP version
MPASM VERSION

Hi,
I am new to this forum: I do have the same problem: I compile a basic program with MP and everything goes fine. If the same program is compiled using MPASM I do have the same error list.
Have you some directions for me ?
Thanks

I'll take a guess, how old is your version of MPASM? I think the new one is 5.14. As Steve mentioned, it's easier to get help if you post the code, and version numbers, as chips, programs, etc. change pretty often, and they update the include files, etc. fairly often.

Hi,
first of all i have to apologize in advance because of my English ( I am Italian ) and because i am very new to this forum and to PIC world.

I wrote a basic program for the 877 target pic and I found stange behaviors of the system.
The source is written using microcode studio.
The program uses a FP routins called DDS in the source file. If the DDS routine is included in a subroutine then i do not have any compiling error BUT the pic does not work at all.
If I call out the routine every time it is needed then the system works . If the routine is called out more than three times then no error during compiling is observed BUT the Pic does not work.
I did several tentative using the MPASM and using the MPLAB : the error lists are attached .
I did rem_out the first two lines of the program using Mpasm. Using Mpasm I did rem_out "c" and "z" register bit declaration to avoid additional errors !
I am not really sure if the use of FP routines have some limitation...
Thanks a lot for any direction on the matter.

How much programming of PICs have you done in your new world?
Have you made a blinky LED yet or anything of the sort? If not, I'd highly suggest building a few simpler 'things' and build up.
The WARNINGs are just that, warnings, and not errors, and generally don't matter much, in this case, they don't mean much.
The last line in the 2nd file...BUILD SUCCEEDED...that's what matters.

the Mpasm is the one included in the MPLAB 8.10

Have you disabled case sensitivity in MPASM? This can cause a lot of odd problems.

[iw2fvo]

hi Bruce,
Yes, I disabled the case sensitive, ( no tick ).
Thanks

Why do you need to use the floating point routines in the first place?
I don't really see a need for them in that code...
