To: "'Gary Thomas'" Cc: ecos-discuss@sourceware.cygnus.com, ecos-discuss@sourceware.cygnus.com, Jonathan Larmour Subject: RE: [ECOS] Help! on building ecosconfigure Date: Thu, 19 Apr 2001 12:16:00 -0000 Message-id: X-SW-Source: 2001-04/msg00214.html Hi, Thanks for the reply.After you have pointed out, that my 'ld' is from arm-linux, instead of arm-elf/xscale-elf,i looked at my tools/biin and realised that xscale-elf-gcc => arm-linux-gcc. So, i changed xscale-elf-gcc => arm-elf-gcc and did a 'make' in my redboot.ROM directory, to build ROM startup files. Guess what!!! It built the binaries!. BUT, after i did 'make clean' and then did 'make'( i want ot build ROM Startup bin files),now, i got a whole bunch of new errors like below. To answer your query on what i used to configure: host=i686-pc-linux target=arm-elf prefix = /home/users/ecoscvs/tools The following info may be usefule for you; xscale-elf-gcc --version = 3.0 xscale-elf-gcc -dumpmachine = arm-elf gcc --version = 3.0 gcc -dumpmachine = i686-pc-linux-gnu Why am i getting these new errors/ does my path is bad? And why did in the mixed up case of gcc and ld, binaries got built. ___Start____ redboot_net_io.o(.text+0xa00): undefined reference to `puts' redboot_net_io.o(.text+0xa4c): undefined reference to `puts' /home/users/redboot.ROM/install/lib/libtarget.a(io_flash_flash.o): In function `flash_erase': io_flash_flash.o(.text+0x2c8): undefined reference to `putchar' io_flash_flash.o(.text+0x2e0): undefined reference to `putchar' /home/users/redboot.ROM/install/lib/libtarget.a(io_flash_flash.o): In function `flash_program' ___End___ On 19-Apr-2001 Narayana, Venkat A. wrote: > Hi, > I have cross-compiled gcc/ld/nm/objcopy/ar/as for 'arm-elf'( i already have > these for 'arm-linux').

When you built these, what "configure" line did you use?
