None Source string added Linux From Scratch part3intro_toolchaintechnotes English	English 0 characters edited Read-only Next comes glibc. The most important considerations for building glibc are the compiler, binary tools, and kernel headers. The compiler and binary tools are generally not an issue since glibc will always use those relating to the <parameter>--host</parameter> parameter passed to its configure script; e.g., in our case, the compiler will be <command>$LFS_TGT-gcc</command> and the <command>readelf</command> tool will be <command>$LFS_TGT-readelf</command>. The kernel headers can be a bit more complicated. Therefore, we take no risks and use the available configure switch to enforce the correct selection. After the run of <command>configure</command>, check the contents of the <filename>config.make</filename> file in the <filename class="directory">build</filename> directory for all important details. These items highlight an important aspect of the glibc package—it is very self-sufficient in terms of its build machinery, and generally does not rely on toolchain defaults. 3 months ago
None Source string added Linux From Scratch part3intro_toolchaintechnotes English	English 0 characters edited Read-only You should also be aware of the name of the platform's dynamic linker, often referred to as the dynamic loader (not to be confused with the standard linker <command>ld</command> that is part of binutils). The dynamic linker provided by package glibc finds and loads the shared libraries needed by a program, prepares the program to run, and then runs it. The name of the dynamic linker for a 32-bit Intel machine is <filename class="libraryfile">ld-linux.so.2</filename>; it's <filename class="libraryfile">ld-linux-x86-64.so.2</filename> on 64-bit systems. A sure-fire way to determine the name of the dynamic linker is to inspect a random binary from the host system by running: <userinput>readelf -l <name of binary> \| grep interpreter</userinput> and noting the output. The authoritative reference covering all platforms is in <ulink url='https://sourceware.org/glibc/wiki/ABIList'>a Glibc wiki page</ulink>. 7 months ago

None Source string added Linux From Scratch part3intro_toolchaintechnotes English	English 0 characters edited Upon entering the chroot environment in <xref linkend="chapter-chroot-temporary-tools"/>, the temporary installations of programs needed for the proper operation of the toolchain are performed. From this point onwards, the core toolchain is self-contained and self-hosted. In <xref linkend="chapter-building-system"/>, final versions of all the packages needed for a fully functional system are built, tested, and installed. 2 years ago
None Source string added Linux From Scratch part3intro_toolchaintechnotes English	English 0 characters edited At the end of <xref linkend="chapter-temporary-tools"/> the native LFS compiler is installed. First binutils-pass2 is built, in the same <envar>DESTDIR</envar> directory as the other programs, then the second pass of gcc is constructed, omitting some non-critical libraries. Due to some weird logic in gcc's configure script, <envar>CC_FOR_TARGET</envar> ends up as <command>cc</command> when the host is the same as the target, but different from the build system. This is why <parameter>CC_FOR_TARGET=$LFS_TGT-gcc</parameter> is declared explicitly as one of the configuration options. 2 years ago
None Source string added Linux From Scratch part3intro_toolchaintechnotes English	English 0 characters edited As mentioned above, the standard C++ library is compiled next, followed in <xref linkend="chapter-temporary-tools"/> by other programs that must be cross-compiled to break circular dependencies at build time. The install step of all those packages uses the <envar>DESTDIR</envar> variable to force installation in the LFS filesystem. 2 years ago

None Source string added Linux From Scratch part3intro_toolchaintechnotes English	English 0 characters edited Detailed information can be obtained from <command>gcc</command> by passing it the <parameter>-v</parameter> command line option while compiling a program. For example, <command>$LFS_TGT-gcc -v <replaceable>example.c</replaceable></command> (or without <command> $LFS_TGT-</command> if coming back later) will show detailed information about the preprocessor, compilation, and assembly stages, including <command>gcc</command>'s search paths for included headers and their order. 2 years ago
None Source string added Linux From Scratch part3intro_toolchaintechnotes English	English 0 characters edited This is important for the reasons mentioned above. It also demonstrates that gcc's configure script does not search the PATH directories to find which tools to use. However, during the actual operation of <command>gcc</command> itself, the same search paths are not necessarily used. To find out which standard linker <command>gcc</command> will use, run: <command>$LFS_TGT-gcc -print-prog-name=ld</command>. (Again, remove the <command>$LFS_TGT-</command> prefix if coming back to this later.) 2 years ago
