compile linux kernel 2.6.0 failed!
hi, I am compiling kernel 2.6.0 with gcc 4.4.5, when linking , here comes the error : /usr/bin/ld: arch/i386/kernel/vsyscall-int80.so: Not enough room for program headers, try linking with -N I suspect that gcc version is not compitable for ld , my ld is 2.20 version . I want to know what does this error mean ? and the general reason for this ? thanks! ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Yes, it does but as you know that the kernel image will be in the compressed format, therefore you'll have to decompress it first.

thanks! do you mean that the compile environment is not confortable for linux2.0? but I find from google that I can do some modify for this done well . gensymb is a tool,which deal with kernel sysmboles.of course,it can be installed .
