Hello!
I am trying to compile the linuxboot ISO on CentOS 5. I have used
Unattended for several years now, but usually with precompiled boot CD's.
However, the 4.9 Beta linuxboot ISO crashes a model of computer I am
trying to load (I'll send another e-mail with this as well), and therefore
I'm trying to compile to correct this issue.
Preliminary Setup:
Very basic CentOS 5.6 install
All optional items unchecked except Base/Base, including GCC
yum update and reboot
yum install samba subversion gcc gcc44 flex bison gcc-c++ mkisofs
svn checkout
https://unattended.svn.sourceforge.net/svnroot/unattended/trunk/
Perform some of the beginning Unattended setup steps that are not really
related to ISO burning: configure Samba, run script-update and prepare,
edit config.pl, copy out the base OS files and hardware drivers.
Steps I've taken to build ISO:
cd <path>/linuxboot
make download
(NOTE: This run ended with an error trying to download Syslinux 4.03.
Another e-mail sent regarding this, but manually updated Makefile to
4.04.)
>From previous personal experience last year at this time, I've found two
errors when compiling the linuxboot ISO on CentOS 5 that seem to continue:
glibc requires GCC 4.4, and it must be built for i686. My build command
reflects these changes:
CFLAGS="-march=i686" make -j 4 CC=gcc44 iso
Build continues until I get to DOSEMU, where the build fails. According
to the research I've done, it seems that DOSEMU does *not* support GCC
4.4: you must use GCC 4.3 or older! Of course, I can't do that because
of glibc, so I'm somewhat stuck.
Obviously, someone is able to build these properly, otherwise there'd be
no 4.9 beta CD. But how? What am I missing?
As an alternative, we do not use DOSEMU, we use the nt5x script. Is there
an easy way to simply skip DOSEMU altogether?
For the record, here's what I did to get around it:
(Clean up half-compiled mess:)
rm -rf dosemu-1.4.0
make download
(Next, force the compile to stop as soon as DOSEMU is done:)
rm -rf e2fsprogs-1.41.12
(Compile without forcing GCC 4.4:)
CFLAGS="-march=i686" make -j 4 iso
(DOSEMU is compiled and the build stops because e2fsprogs is now
missing)
Obviously, this is an ugly hack. My makefile-fu is weak, so I had to kind
of brute-force it. Suggestions for a more elegant solution greatly
appreciated. However, now that DOSEMU is done, I can continue with a
normal build with GCC 4.4:
(Put e2fsprogs back)
make download
(Continue build)
CFLAGS="-march=i686" make -j 4 CC=gcc44 iso
I now get an error with pciutils and lspci, but that will be a separate
e-mail.
Thank you very much for any help you might be able to give me. Please ask
if you have any questions: I have tried to cut down on extraneous
information, but I have a lot more detail if you need it!
