ANTTI*HAPPY: building MicroBlaze uClinux on WinXP full sucess !!

thanks Antti,

Very nice and interesting job. Happy for you !

Do you know what caused the issues with compiling busybox and sh? Is it a build script issues, a cygwin issues, or a gcc issue?

"11.now you get core dump whild building busybox and sh, those need to be pulled out and compiled out of tree and then injected back

12.the busybox and sh need to be >

Hi Paul

I have found following issues

1)

/user/mount/mount.c C compiler parse error !?

2) /user/sh and user/busybox

both fail on final linking or elf2flt conversion when invoked from main build tree, so as a workaround I let the busybox to be compiled into .a and .o files inside the main build tree, then copy out the .a and .o and run link elf2flt in out of tree setup, then copy the busybox executable back into main tree

both cause 'core dump' when in main tree, but sh also cause core dump in out of tree, during elf2flt so for sh I invoke the elf2flt again after out of tree build

this is busybox when in main tree

ok, let ma attach the makefiles that I use for busybox/sh out of tree

the busybox makefile does produce flat exe from makefile

the sh make file produces

so I convert it after make manually with bat file

mb-elf2flt sh.elf copy sh.elf.bflt sh

this sh is correct working exe !

I assume the issues are in the elf2flt mainly

3) all flat exes produced have .elf.bflt extension so I had to modify the makefiles to get proper exe names, dont know what is causing this or where would the proper fix to this issue belong too
