v3.1.1

  • Build system portability fixes
  • Fix make check exit code

v3.1.0

  • Add a --max-depth flag to limit recursion depth. For example, libtree --max-depth 1 <file> will show the resolved direct dependencies only.

v3.0.4

  • Build system portability fixes
  • Fix make check exit code

v3.0.3

  • libtree -vvvv... is now treated as libtree -vvv.

v3.0.2

  • Improve make check, make clean and CI
  • Preserve original timestamps when installing files
  • Add rpath order test

v3.0.1

  • Fix man pages directory in make install
  • Skip dynamic linker on aarch64 and powerpc

v3.0.0

  • Rewritten in C99 with 0 external dependencies.

  • Significantly faster & smaller (~50KB statically compiled with musl libc, or even smaller than the source file with diet libc).

  • Cross-compiled binaries now available thanks to binarybuilder.org

  • Improved search path printing when libraries cannot be located.

  • Improved rpath search: shows [rpath of ...] when lib is located by parent of parent ... of parent's rpath.

  • fd inspired highlight of filename when printing paths.

  • Caches files by inode instead of soname, which is useful in the sense that this allows you to find broken libraries that only work because of a particular search order of the tree. (Consider an executable A and libraries B, C and D, where A depends on B and C, and B and C depend on D:

      B
 / \
A   D
 \ /
  C

    It may happen that D can be located through B's rpath, but not through C's. Then, depending on whether A - B - D is traversed first, or A - C - D, ld.so will complain about missing libraries or not. libtree on the other hand will always tell you that D can't be located through C.

  • More verbosity levels -v, -vv, -vvv instead of -a and -v flags.

  • Skip fewer libraries by default (only libc / libstdc++ type of libs).

  • PLATFORM rpath interpolation now uses uname, this is not always the same as AT_PLATFORM, but unlikely to be different, and in fact the feature is rarely used.

  • Support for NODEFLIB flag, which is a dynamic array entry flag that signals to the dynamic linker that it should not search default system paths including those specified in ld.so.conf.

  • Better FreeBSD support (OSREL, OSNAME interpolation in rpaths and /etc/ld-elf.so.conf config file support)

  • Support for relative includes in ld.so.conf config files.

Breaking changes:

  • The bundling feature was dropped in 3.0.0, but is still supported in 2.x. It may return in a future 3.x release, but my impression is that there are excellent tools like Exodus which do a better job at bundling (in particular: they ship a copy of the dynamic linker.)
  • The --skip and --platform flags were removed.

v2.0.0

  • No changes to the libtree API
  • Provide static executables for ease of use on distros with an old glibc or musl.
  • Dropped the dependency on cppglob, use posix glob instead.
  • No more vendored dependencies, rely on find_package to find cxxopts, elfio, and termcolor.
