As found out by Yann E. Morin in [1], apcupsd configure script is ugly,
and uses gcc to do the link line-wrapping which will raise the following
build failure with gcc 13:
/home/buildroot/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/powerpc64le-buildroot-linux-gnu/13.2.0/../../../../powerpc64le-buildroot-linux-gnu/bin/ld: /home/buildroot/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/powerpc64le-buildroot-linux-gnu/13.2.0/../../../../powerpc64le-buildroot-linux-gnu/lib/../lib64/libsupc++.a(eh_alloc.o): in function `std::basic_string_view<char, std::char_traits<char> >::compare(unsigned long, unsigned long, char const*, unsigned long) const':

It will also raise the following build failure on sparc/arc:
/home/autobuild/autobuild/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arceb-snps-linux-uclibc/9.2.1/../../../../arceb-snps-linux-uclibc/bin/ld: /home/autobuild/autobuild/instance-3/output-1/host/arceb-buildroot-linux-uclibc/sysroot/lib/libsupc++.a(eh_throw.o): in function `__exchange_and_add_dispatch':

/home/autobuild/autobuild/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arceb-snps-linux-uclibc/9.2.1/../../../../arceb-snps-linux-uclibc/bin/ld: /SCRATCH/arcjenkins2/slaves/ru20-custom-arcgnu2/workspace/arcoss_verification/arc_gnu_toolchain_release/arc_gnu_toolchain_release/bd-uclibceb/gcc-stage2/arceb-snps-linux-uclibc/libstdc++-v3/include/ext/atomicity.h:82: undefined reference to `__gnu_cxx::__exchange_and_add(int volatile*, int)'
Instead of trying to patch the configure script as advocated by
Yann E. Morin, set LD to TARGET_CXX as:
- this solution is quicker
- usptream is dead (last release in 2016)
- this solution has already been used in other packages (nodejs, zmqpp)

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
