* lddtree: keep relativeness of invoked program in elf wrapperTakuto Ikuta2023-12-221-1/+5

Instead of enforcing relative path, I keep relativeness of compiler path. I confirmed this works as following with a debug line to show ${base}.elf.

* Fix fuzz-dumpelf testAliaksei Urbanski2023-11-232-1/+11
| | | | | | | | | | | | | | Not sure why, but the dumpelf.fuzz fuzzer fails when it's calling prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, ...) at security_init. So I suggest disabling seccomp for fuzzy testing. Also, in order to not run indefinitely, the fuzzer must be executed with some reasonable options. https://releases.llvm.org/14.0.0/docs/LibFuzzer.html#options Signed-off-by: Aliaksei Urbanski <aliaksei.urbanski@gmail.com> Closes: https://github.com/gentoo/pax-utils/pull/13 Signed-off-by: Sam James <sam@gentoo.org>

* meson: include generated man pages in dist tarballsSam James2022-11-023-13/+38
| | | | | | | | | | | | | | | | | Meson doesn't have an idiomatic way of doing this (for once!) so we have to (per Eli Schwartz, thanks!) have: 1. a dist script which duplicates the build rule; 2. some meson.build if/else logic with fs.exists() to prefer the built manpage when using tarballs Sadly, still can't easily regenerate man pages if you apply a patch downstream though. We use Michael Stapelberg's example from the linked bug as inspiration.

* Probe the target system for needed headersArsen Arsenović2022-07-122-15/+12
| | | | | | | | | | | This prevents new or unconventional systems requiring upstream changes, though, this is not perfect, as it doesn't address some of the other defines related to OSes the preprocessor does (namely, wrt the ldso cache handling).

* Convert build system to mesonArsen Arsenović2022-07-1228-769/+295
| | | | | | | | | | | | | | | | | Some notes about the new build systems: - I don't fully understand the testing system, but I think I understood it well enough to implement an equivalent one. - use_seccomp could be replaced by detecting seccomp support at runtime (without support, Linux returns -EINVAL in include/linux/seccomp.h) - The fuzzing test is broken and seems to have been for a while (see commit 67f3ba64c91b5e1ac9fbbd0bc039fb8ca653cae1, it fails to fuzz on my machine) - make-tarball.sh has been replaced with meson dist - hopefully this works. meson dist should also call seccomp-bpf.c to update seccomp-bpf.h Signed-off-by: Arsen Arsenović <arsen@aarsen.me> Signed-off-by: Sam James <sam@gentoo.org>
