The binutils-gdb code base in Git does have a copy of readline that is used by gdb. The release tarballs of binutils do NOT contain readline as it's not needed for binutils itself (only gdb). However, when we build the ARC binutils, taken from Git, the readline/ folder is present, and therefore readline is built even if it is not actually needed. This causes build failures as the copy of readline in ARC binutils 2024.12 (based on binutils 2.43) does not build with GCC 15.x. To work around this problem, we use a suggestion from Waldemar Brodkorb: pass --with-system-readline. Indeed, this disables the build of readline... but it does not actually check that we have a system readline, since we're not building gdb.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
