kandi X-RAY | libdatrie Summary

libdatrie is a C library. libdatrie has no bugs, it has no vulnerabilities, it has a Weak Copyleft License and it has low support. You can download it from GitHub.

This is an implementation of double-array structure for representing trie, as proposed by Junichi Aoe [1]. Trie is a kind of digital search tree, an efficient indexing method with O(1) time complexity for searching. Comparably as efficient as hashing, trie also provides flexibility on incremental matching and key spelling manipulation. This makes it ideal for lexical analyzers, as well as spelling dictionaries. See the details of the implementation at [2]: Historically, this was first implemented as C++ classes in a library called midatrie [2], but later simplified and rewritten from scratch in C.

QUESTION

Why does cmake's installed files differ from the actual built binary?

Asked 2020-Sep-22 at 06:32

I am building couple of libs in ubuntu using CMake, and I noticed whenever I try to use the files in the installed directory, I get missing libs error. using ldd I noticed in these files, the libs are not found while if I go back to the original file built, it has all the references and copying it to the installation directory fixes the issue. To make all this more clear consider the following CMakeList.txt that I use to build my library:

This is normal behavior in CMake. When compiling you binaries the rpath to the dependencies is set in the binary, but stripped when installing it.

By default if you don't change any RPATH related settings, CMake will link the executables and shared libraries with full RPATH to all used libraries in the build tree. When installing, it will clear the RPATH of these targets so they are installed with an empty RPATH. Source

When looking up runtime dependencies the rpath is preferred over the default directories (see https://stackoverflow.com/a/33520976/4181011). But since the rpath was removed from your library it doesn't know about you "out-of-default-directories"-dependencies.

You can manipulate the lookup with LD_LIBRARY_PATH, LD_PRELOAD or by adding the additional path to the lookup directories using ldconfig.

Use gcc to link and use -Wl,-Bstatic to tell the linker to prefer linking against static libraries rather than shared ones. Example:

It looks like the issue is that this datrie package supports at most 255 values for characters in the keyset: https://github.com/pytries/datrie/blob/master/libdatrie/datrie/alpha-map.h#L59

I recommend using marisa_trie::RecordTrie from here: https://pypi.python.org/pypi/marisa-trie

Unfortunately it's a static data structure, so you cannot modify it after building, but it fully support unicode, serialization to disk, and all sorts of value types.
