If I include malloc.c, free.c and init_mem.c from Keil/C166/Lib directory into my project it will not link. I get the following linker errors: *** WARNING L7: MODULE NAME NOT UNIQUE MODULE: C:\KEIL\C166\LIB\C167XL.LIB (INIT_MEM) and also *** ERROR L128: REFERENCE MADE TO UNRESOLVED EXTERNAL SYMBOL: malloc MODULE: RICOSRTXC.OBJ (RICOSRTXC) ADDRESS: 1FD3H There is a lot of those. Can someone please tell me how to get the replacements of the memory allocation routines for XLARGE.
