Problems when doing building the project,please help.

[stev...@live.cn]

Hi All,

When I try to build the heli project I received the following message
at the very end:

c:\program files\microchip\mplab c30\bin\bin\..\bin/pic30-coff-ld.exe
Error: A heap is required, but has not been specified
c:/program files/microchip/mplab c30/bin/bin/../../lib\libc-
coff.a(vsnprintf.o)(.libc.vsnprintf+0x1e):fake: undefined reference to
`assert'
c:/program files/microchip/mplab c30/bin/bin/../../lib\libc-
coff.a(vsnprintf.o)(.libc.vsnprintf+0x22):fake: undefined reference to
`alloc'
BUILD FAILED: Mon Dec 20 05:49:10 2010

Does anyone know how to fix these problems?
I am using the C30 compiler v3.25 and MPLAB v7.5.
Thanks.

Hi Steven

Compiler problems are sometimes difficult to trace down. Here are a couple
things you might try:

Be sure libdsp-coff.a is showing up under Library Files and p30f4011.gld
under Linker Script in your mcw window

Build using the Build All option

Be sure you are in Release Mode at the top of the IDE.

If this doesn't solve the problem, let me know.

Hi John,

I am still getting the same errors. Is there any other way to solve
these problems? Thank you.

I'm trying to build the MP-Quad project and get the following errors:

c:/program files/microchip/mplabc30/v3.25/bin/bin/../../lib\libc-

coff.a(vsnprintf.o)(.libc.vsnprintf+0x1e):fake: undefined reference to
`assert'

c:/program files/microchip/mplabc30/v3.25/bin/bin/../../lib\libc-

coff.a(vsnprintf.o)(.libc.vsnprintf+0x22):fake: undefined reference to
`alloc'

Link step failed.

I have both libdsp-coff.a and p30f4011.gld in the mcw window.

I'm using mplabCV3.25

I also tried creating a new project and adding the source files but
get the same errors

Any thoughts?

Bryan

I switched to an older MPLAB version and I can build now....

it seems to be a linker issue with cV3.25
