Help with ncrt0 please!

Hello, I have some problems when trying to compile a file.c with the nc30 compiler. The chip I use is a mitsubishi. I don't know anything about assembly. I just modified the C source. I read the manual of the nc30 compiler (nc30ue.pdf). I was able to obtain the AA.r30 file from the AA.c. Now, what is ncrt0.a30? When I lauch ln30 I get the following error messages:

ncrt0.a30 172 Error (asp30): Undefined symbol exist 'heap_top'

or

ncrt0.a30 96 Error (asp30): Section name is missing 'data_FO'

The number of errors is 54! They are all like these. What can I do? As I have already said I don't need to modify any file except the AA.c, but because I don't know even what the ncrt0 file is, I'm lost. I know the informations I gave are not exhaustive, so ask everything you need, I'll try to answer... Please help me! Thanks a lot, Luke

ncrt0.a30 is the startup file. It includes file sect30.inc. Both of those files need to be modified for your hardware and application.

Thank you very much. I found the sect30.inc and the errors vanished! I hope I won't need to modify those files, as they should be already ok. Thanks again! Luke

I have another problem. I have the ncrt0.r30, sect30.inc and my cb_e464.r30. When I run ln30 I get the following errors:

Linkage Editor (ln30) for M16C Family Version 4.00.01 Copyright 2000, MITSUBISHI ELECTRIC CORPORATION AND MITSUBISHI ELECTRIC SEMICONDUCTOR SYSTEMS CORPORATION All Rights Reserved.

[...]

== too many errors and warnings ==

There are so many errors that I think I have the wrong files, but as I don't know what these files are I don't know what to look for.

The lines 145-151 of sect30.inc are the following:

.section vector ; variable vector table .org VECTOR_ADR

.lword dummy_int ; BRK (vector 0) .org (VECTOR_ADR+16) .glb _VoutAltaSoglia1 .lword _VoutAltaSoglia1

Again, I'm lost. Once I manage to obtain the .x30 file from the .c file I should be ok. I have some versions of the files, but I don't know which is the right one! Please help me! Thank you very much Luca

Sounds like you are missing a file.
