The preliminary draft was rejected by 107 the kernel maintainers and it's fundamentally incompatible with 108 the packages we will built for LFS. Such <quote>old-world</quote> 109 distributions (for example, Loongnix) cannot be used as a host 110 distro for building LFS. 111 </para> 112 113 <para> 114 Do not attempt to update the kernel to &min-kernel; or later on 115 a old-world distro because doing so will cause a boot failure. 116 Use a <quote>new-world</quote> distribution providing Linux Kernel 117 &min-kernel; or newer instead. You may need to contact the vendor 118 of your hardware to get a firmware update for booting a new-world 119 distribution because the boot protocol of LoongArch is stabilized 120 after the launch of the early LoongArch hardwares. 121 </para> 122 </important> 100 <xref linkend="chapter-building-system"/>, so the workarounds for 101 older kernels are not enabled and the compiled 102 <application>glibc</application> is slightly faster and smaller. 103 As at Feb 2024, &min-kernel; is the oldest kernel release still 104 supported by the kernel developers. Some kernel releases older than 105 &min-kernel; may be still supported by third-party teams, but they 106 are not considered official upstream kernel releases; read 107 <ulink url='https://kernel.org/category/releases.html'/> for the 108 details.</para> 109 110 <para>If the host kernel is earlier than &min-kernel; you will need to replace 111 the kernel with a more up-to-date version. There are two ways 112 you can go about this. First, see if your Linux vendor provides a &min-kernel; 113 or later kernel package. If so, you may wish to install it. If your 114 vendor doesn't offer an acceptable kernel package, or you would prefer not to 115 install it, you can compile a kernel yourself. Instructions for 116 compiling the kernel and configuring the boot loader (assuming the host 117 uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para> 123 118 124 119 <para>We require the host kernel to support UNIX 98 pseudo terminal … … 233 228 ver_check Coreutils sort 8.1 || bail "Coreutils too old, stop" 234 229 ver_check Bash bash 3.2 235 ver_check Binutils ld 2. 38230 ver_check Binutils ld 2.13.1 236 231 ver_check Bison bison 2.7 237 232 ver_check Diffutils diff 2.8.1 238 233 ver_check Findutils find 4.2.31 239 234 ver_check Gawk gawk 4.0.1 240 ver_check GCC gcc 12.2241 ver_check "GCC (C++)" g++ 12.2235 ver_check GCC gcc 5.2 236 ver_check "GCC (C++)" g++ 5.2 242 237 ver_check Grep grep 2.5.1a 243 238 ver_check Gzip gzip 1.3.12 -
