- I'm not looking for fewer unusual problems, I want to learn how this works and figure out what's going on so I can solve these problems on my own.
- I'm not using bleeding edge version of everything, I've gone through the trouble to check out the appropriate branches in all repositories and if that’s not enough, I've reset to specific commit hashes just to be sure. - I insist on adjusting my versions according to this: http://www.linuxfromscratch.org/lfs/view/development/ if someone else can get that to work then I should be able to as well. - you guys don’t post section 4.4 and 5.2 here ? http://www.linuxfromscratch.org/lfs/view/development/ - I'm sorry but the only reason I top-posted was to add additional information that I thought would be helpful in getting information as to what is going on with my toolchain. I also use a thread view email client. -----Original Message----- From: lfs-support-boun...@linuxfromscratch.org [mailto:lfs-support-boun...@linuxfromscratch.org] On Behalf Of Ken Moffat Sent: Wednesday, November 14, 2012 11:22 AM To: LFS Support List Subject: Re: [lfs-support] still doesnt work right (after binutils pass 2) On Wed, Nov 14, 2012 at 10:38:45AM -0800, Paige Thompson wrote: > dev@dev-VirtualBox /mnt/erraticOS/tools/bin $ strace ./as > > execve("./as", ["./as"], [/* 28 vars */]) = 0 > > brk(0) = 0x1432000 > > mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, > 0) = > 0x7f59289d4000 > > access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or > directory) > [...] > > open("/tools/lib/libc.so.6", O_RDONLY|O_CLOEXEC) = 3 > > read(3, > "\177ELF\2\1\1\3\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\300\27\2\0\0\0\0\0"... > , 832) = 832 > > fstat(3, {st_mode=S_IFREG|0755, st_size=9593885, ...}) = 0 > > mmap(NULL, 3824768, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, > 0) = > 0x7f592840f000 > > mprotect(0x7f59285ab000, 2097152, PROT_NONE) = 0 > > mmap(0x7f59287ab000, 24576, PROT_READ|PROT_WRITE, > MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x19c000) = 0x7f59287ab000 > > mmap(0x7f59287b1000, 15488, PROT_READ|PROT_WRITE, > MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x7f59287b1000 > > close(3) = 0 > > mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, > 0) = > 0x7f59289d3000 > > mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, > 0) = > 0x7f59289d2000 > > mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, > 0) = > 0x7f59289d1000 > > arch_prctl(ARCH_SET_FS, 0x7f59289d2700) = 0 > > mprotect(0x7f59287ab000, 16384, PROT_READ) = 0 > > mprotect(0x7f59289d5000, 4096, PROT_READ) = 0 > > --- SIGSEGV (Segmentation fault) @ 0 (0) --- > > +++ killed by SIGSEGV +++ > > Segmentation fault > > dev@dev-VirtualBox /mnt/erraticOS/tools/bin $ > Possibly, you need to do something specific to build in VirtualBox.

I suggest that you use the latest release of the LFS book until you can successfully build it. You seem to have a lot of knowledge of some things, but you don't seem to understand *how* we build LFS. I'm sure that will come, if you stick with it. > Using built-in specs. > > COLLECT_GCC=/mnt/erraticOS/tools/bin/x86_64-linux-gnu-gcc > Does a /mnt/lfs directory (or symlink, I suppose) exist ?

And for preference make /mnt/erraticOS a symlink to /mnt/lfs - you will get fewer unusual problems by doing that. I'm sure it is possible to use the bleeding edge versions of everything (modulo occasional new difficulties, and things which get reverted before a package is released), but it needs a lot more effort. Also, (re)read the Host System Requirements in the preface (ALL of them need to pass), section 4.4 Setting Up the Environment, and the Toolchain Technical Notes in section 5.2 Lastly, please don't add unnecessary blank lines when pasting (or strip them if you are posting a long part of a log from a windows machine), and don't top post. Thanks, and good luck. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
