Hi list,I tried building linuxboot from SVN, and "make iso" stops during glibc build, because TLS support is "missing". Here's some relevant info from config.log:
configure:7: checking for i386 TLS support configure:29: gcc -c -g -O2 conftest.s 1>&5 conftest.s: Assembler messages:conftest.s:8: Error: @TLSLDM reloc is not supported with 64-bit output format
conftest.s:8: Error: junk `...@tlsldm' after expressionconftest.s:9: Error: relocated field and relocation type differ in signedness conftest.s:10: Error: relocated field and relocation type differ in signedness conftest.s:11: Error: relocated field and relocation type differ in signedness conftest.s:12: Error: @GOTNTPOFF reloc is not supported with 64-bit output format
conftest.s:12: Error: junk `...@gotntpoff' after expressionconftest.s:14: Error: @NTPOFF reloc is not supported with 64-bit output format
conftest.s:14: Error: junk `...@ntpoff' after expression configure:32: $? = 1 configure:40: result: noThe only thing I could find on Google referencing this error is: http://bugs.gentoo.org/show_bug.cgi?id=266172 ... Which doesn't help me at all. The suggestion is to update to glibc 2.9 and we already use 2.11.1.
This is my build system: uname -aLinux cn212570 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux
Seems like a cross-compiling problem! According to [1] "If you specify just ‘--build’, |configure| will get confused." So I changed it to use --host in the Makefile. To cross-compile gclibc properly, the -m32 argument must be passed to gcc. After that, I hit another problem [2]. Finally, I came up with the attached patch. (Yeah, it's ugly ... I tried setting those options in CFLAGS and CXXFLAGS where they belong, but it doesn't work ... ?!)
I'm curious what else needs some similar cross-compiler fixes to get linuxboot to build properly?
Finally, I tried the linuxboot-4.9 iso from SF. The kernel won't boot from the CD on a Dell Inspiron 400 (Zino HD); it says "cannot find `image`" or some similar error. That's why I was trying to build my own. ;(
