dBug build problem under Linux

GunnarRistroph — Tue, 18 Jul 2006 02:39:19 GMT

I am trying to build dBug so I can use it to build my own boot loader for the M5208EVB.

When I type "make m5208evb", I get the following error:

No rule to make target `obj/m5208evb/gnu/board/m5208evb/src/uClinux_and_SBCTools/delay.o', needed by `all'.

The top level Makefile calls proj/m5208/build/gnu/m5208evb.make which includes build/gnu/mcf5xxx.comp and build/common.objs. No where is there a make target that tells how to make the list of objects found in OBJS.

Is there a simple fix or something that I am overlooking?

Development environment: Debian 2.6.15 with m68k-elf-tools-20030314. Using 5208_DBUG.zip downloaded from the Freescale website.

The top level Makefile calls proj/m5208/build/gnu/m5208evb.make which includes build/gnu/mcf5xxx.comp and build/common.objs AND build/gnu/cf.rules.lst.

The make targets for things in OBJS are in this file - build/gnu/cf.rules.lst, but it still isn't working, (possibly because make isn't matching the names).

To summarize progress so far, I downloaded 5208_DBUG.zip from the freescale website and unzipped it. I then:

1) converted all files to unix line endings:
find . -type f -print -exec fromdos \{\} \;

2) make bin files executable:
chmod a+x bin/*

3) change the name of uClinux_and_SBCTools to "tools" because make was having a hard time matching it (by the way: it should be uClinux NOT ucLinux), I changed the existing directory names and all refences to it in all files (just a couple of these)

4) replaced C:/SBCToolsV2/Standard/ColdFire/gcc/m68k-elf-3.3.2/bin with /usr/local/m68k-elf/bin in build/gnu/mcf5xxx.comp and C:/SBCToolsV2/Standard/ColdFire/gcc/m68k-elf-3.3.2/lib/gcc-lib/m68k-elf/3.3.2/m5307 with /usr/local/lib/gcc-lib/m68k-elf/2.95.3/m5307

This gets me most of the way there, but not quite.

After making the objects, I get:

Well, I solved the undefined "main" problem and the not enough room in ram_data problem... but now there are undefined references to atexit from libgcc.

To summarize progress so far, I downloaded 5208_DBUG.zip from the freescale website and unzipped it. I then:

1) converted all files to unix line endings:
find . -type f -print -exec fromdos \{\} \;

2) make bin files executable:
chmod a+x bin/*

3) change the name of uClinux_and_SBCTools to "tools" because make was having a hard time matching it (by the way: it should be uClinux NOT ucLinux), I changed the existing directory names and all refences to it in all files (just a couple of these)

4) replaced C:/SBCToolsV2/Standard/ColdFire/gcc/m68k-elf-3.3.2/bin with /usr/local/m68k-elf/bin in build/gnu/mcf5xxx.comp and C:/SBCToolsV2/Standard/ColdFire/gcc/m68k-elf-3.3.2/lib/gcc-lib/m68k-elf/3.3.2/m5307 with /usr/local/lib/gcc-lib/m68k-elf/2.95.3/m5307

5) modified /proj/m5208evb/build/gnu/flash.ld to make data_ram bigger because they gave an error (probably because of difference in gcc versions)

6) renamed dbug_main to main in src/uif/main.c because that was preventing it from linking

This gets me most of the way there, but not quite.

After making the objects, I get:

linking with libc.a by adding -lc to the linker options (right after -lgcc) solve the unresolved "atexit" problem (even though atexit isn't actually used), but then creates a conflict with "malloc" because "malloc" is defined in libc.a, but also has a definition in the dBug code, so I'll probably rename "malloc" to "mymalloc" or something

also, I've switched to using gcc 4.1.1

GunnarRistroph — Thu, 20 Jul 2006 03:01:33 GMT

(I'm concerned that it may have linked with libc's malloc and not the malloc in src/uif/alloc.c)

The m5208evb_flash.s19 file worked (programmed frow MS Windows with CF Flasher), so I guess it used the right malloc.
