cc65 question

[TGB1718]

I'm writing a device handler in cc65, it has a .c file and a .s file,

I want to produce a listing of the build, I have '--listing centxe.lst' in the build call, but all it

produces is a listing file of the .s file, not the .c file which is a bit daft as I already have the .s listing.

 

Here's the call to build, any ideas as what I'm doing wrong, pretty sure I've seen the correct ouput before on another project.

 

cl65 -t atari -O -Wl "-D__RESERVED_MEMORY__=1" --static-locals --listing centxe.lst centxe_main.c centxe_asm.s -o centxe.xex

 

this is what I get:-

You're using a much later version that I did, but just a -l on the cl65 command should do it. You have a -Wl, but I don't see just the -l. I am not familiar with --listing, they must have added that one (or I ignored it it for the shorter form). At any rate I did not have issues using mixed .c and .s files with output listings.

[TGB1718]

-l = --listing although on the cc65 web page it doesn't mention -l is the short form

I changed the build script to

 cl65 -t atari -O "-D__RESERVED_MEMORY__=1" --static-locals -l centxe.lst centxe_main.c centxe_asm.s -o centxe.xex

 

but still only the .s file is produced in the listing

 

Interestingly I just tried with an older project that doesn't have a .s but does have 2 .c files and only one of them is produced

in the listing and again, not the MAIN.C program file, really odd behavior.

[TGB1718]

Think I've solved it, it would appear only one file can be listed at a time and it looks like it's the last file on the

command line, this now producing a listing for the .c file but not the .s

 

cl65 -t atari -O "-D__RESERVED_MEMORY__=1" --static-locals -l centxe.lst -o centxe.xex centxe_asm.s centxe_main.c 

 

So it's a 'quirk/bug' in cc65

[sanny]

If you have more than one source file you can compile each source file separately (with optional different option) with the "-c" command line switch. Then link all the object files together.

Example:

 

$ cl65 -t atari -c -o file1.o  file1.s
$ cl65 -t atari -c -o file2.o  file2.c
$ cl65 -t atari    -o prog.com file1.o file2.o

 

[sanny]

And, if an asm source file is OK instead of a "listing", use cc65.

 

cc65 translates a file from C to assembler (it's called under the hood by cl65)

[TGB1718]

Many thanks @sanny that makes much more sense to compile individually and link later.

 

Update: Works a treat with the -c thanks again
