I want to compile the eCos for MCF5272EVB which is supported by eCos. But I
got the
follow error message:

preprocessing token
The file mlt_m68k_mcf52xx_mcf5272_mcf5272 3_ram.ldi is :

I have marked the line 53. This file is included in the link command file,
but I can't find
GENERIC_SECTION command in the syntax reference of ld script language. What
does it mean?
Sorry, I am a newbie for eCos. Could anybody help me?
thx.
