problem with dynamic memory in multi-files project

[iporboon]

Dear sir.
I used PIC18F4553 and PIC16F877 with CCS V4.
I did multi-file compilation unit for my project and it worked fine.
But when I used dynamic memory functions (calloc/malloc) in my programs, those functions did not work. They returned NULL pointers.

I read the Multiple Compilation Units topic in Help file and followed it.
I also included stdlibm.h in the common header file of the project.
I debugged it with MPLABSIM and I saw the variable DYNMIC_HEAD was zero, that caused malloc/calloc returned NULL pointer .

I also did single-file project with malloc/calloc and it worked correctly.

Best Rgds.
