I am too having problems getting sdcc to compile for the above chip. I have tried several times, but I get the following warnings....
$ sdcc BD.c -mpic14 -p12f675

message: using default linker script "/usr/local/share/gputils/lkr/12f675.lkr"
error: linker script has no definition that matches the type of section "data_BD"
Can anyone help me to fix these problems.
Many thanks in advance,

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Rumor says, that posting (short but nearly compiling) code often helps others to find the problems...
However, the problem is likely to reside in gputils' 12f675.lkr linker script: It only contains SHAREBANKs, no (unprotected) DATABANKS.
If you replace the two lines
SHAREBANK NAME=gpr0nobnk START=0x20 END=0x5F
SHAREBANK NAME=gpr0nobnk START=0xA0 END=0xDF
with a single
DATABANK NAME=gpr0nobnk START=0x20 END=0x5F
you should be up and running, though the resulting code will probably introduce unneccessary BANKSELs (the line above states that all RAM resides in bank 0, although every cell is addressable via bank 1 as well (shared bank)). I guess the 12f675 only offers 64 bytes of RAM, right?
HTH,

As a follow up to this post, I have downloaded 2.6.0 and now I only get the error message.
error: linker script has no definition that matches the type of section "data_BD"
I've looked at the .asm for this and can see the following lines....
;--------------------------------------------------------
; udata
;--------------------------------------------------------
data_BD udata
; .area DSEG (DATA)
I am using both cygwyn and win32 sdcc compilers, but get the same error message with both.
Can anyone help...?
Many thanks in advance,
Richard
