コマンド説明

mkdir build; cd build: The GCC documentation recommends building the package in a dedicated build directory.

--disable-multilib: This parameter ensures that files are created for the specific architecture of your computer.

--with-system-zlib: Uses the system zlib instead of the bundled one. zlib is used for compressing and decompressing GCC's intermediate language in LTO (Link Time Optimization) object files.

--enable-default-pie: Makes the -fpie option the default when compiling programs. Together with the ASLR feature enabled in the kernel, this defeats some kind of attacks based on known memory layouts.

--enable-default-ssp: Makes the -fstack-protector-strong option the default when compiling programs. SSP is a technique preventing alteration of the program flow by corrupting the parameter stack.

--enable-languages=c,c++,fortran,go,objc,obj-c++,m2: This command identifies which languages to build. You may modify this command to remove undesired languages. GCC also supports Ada and D, but building GCC with Ada (or D) support needs an existing Ada (or D) compiler. So they are not enabled here.

ulimit -s 32768: This command prevents several tests from running out of stack space.

make -k check: This command runs the test suite without stopping if any errors are encountered.

../contrib/test_summary: This command will produce a summary of the test suite results. You can append | grep -A7 Summ to the command to produce an even more condensed version of the summary. You may also wish to redirect the output to a file for review and comparison later on.

mv -v /usr/lib/*gdb.py ...: The installation stage puts some files used by gdb under the /usr/lib directory. This generates spurious error messages when performing ldconfig. This command moves the files to another location.

chown -v -R root:root /usr/lib/gcc/*linux-gnu/...: If the package is built by a user other than root, the ownership of the installed include directory (and its content) will be incorrect. This command changes the ownership to the root user and group.

--enable-host-shared --enable-languages=jit: Build libgccjit, a library for embedding GCC inside programs and libraries for generating machine code. Despite 「JIT」 (just-in-time) in the name, the library can be used for AOT (ahead-of-time) compilation as well. --enable-host-shared is needed for building libgccjit, but it significantly slows down GCC. So libgccjit should be built and installed separately, not as a part of the 「main」 GCC installation. If you need this library, configure GCC with these two options and install the library by running make -C gcc jit.install-common jit.install-info as the root user. This library is not used by any BLFS package, nor tested by the BLFS developers.
