node-gyp hatası: Sembol bulunamadı

Question

Ben de aynı soruyu bulduğum en yakın şey bu (aynı zamanda cevapsız) soru oldu:

Symbol not found: _libintl_gettext

Ben libpuzzle için ince bir C++ sarmalayıcı yapmaya çalışılıyor. inşa etmek çalışılıyor

$ node --version 
v0.8.18 
$ npm --version 
1.2.4 
$ node-gyp --version 
v0.8.3 

Source code on github

Tamam (Ben eli ile yolları ... kısa ettik), bu nedenle bu hata, bana açıkça olamaz mantıklı dinamik bir kütüphane yükleyin.

İlk başta, bağlantı ayarlarını eklemek için binding.gyp numaralı telefonumu ayarlamam gerektiğini düşündüğümden, birkaç farklı yapılandırmayı denedim.

$ ll /opt/local/lib/libpuzzle.*

-rwxr-xr-x 1 root admin 1.2K Sep 2 23:59 /opt/local/lib/libgd.la 

Sadece görmek için dyld nasıl bilemiyorum: Burada kütüphanelerini var

{ 
    "targets": [ 
     { 
      "target_name": "puzzle", 
      "sources": [ "puzzle.cc" ], 
      "link_settings": { 
       "libraries": [ 
        "/opt/local/lib/libgd.dylib", 
        "/opt/local/lib/libpuzzle.dylib" 
       ], 
      } 
     } 
    ] 
} 

: Şu anda böyle görünüyor şeydir. DYLD_FRAMEWORK_PATH ve DYLD_FALLBACK_LIBRARY_PATH'yi boşuna kullanmamaya çalıştım.

gelen dyld hakkında değiştirilmiş sembolü __Z19puzzle_init_contextP14PuzzleContext_ olduğunu. Onun unmangled formunda, puzzle_init_context(PuzzleContext_*). Mandallama, derleyici tarafından bir C++ sembolü olarak kabul edildiğini gösterir. Ancak, libpuzzle saf bir C arayüzü ihraç ediyor gibi görünüyor. Bu, 'un aradığı sembolü _puzzle_init_context olduğunu gösterir. Derleyiciye, üstbilginin içeriğinin C kodu olarak algılanması gerektiğini bildirmek için #include <puzzle.h> kodunu bir extern "C" { … } satırına sarmak suretiyle düzeltebilirsiniz, böylece sembol adlarını uygun kurallara göre işleyecektir.

Bu tür bir hata, genellikle dinamik bağlayıcı tarafından çalışma zamanında değil statik bağlantı tarafından algılanır. Hata iletinizin Expected in: dynamic lookup bölümü, puzzle.node'un -undefined dynamic_lookup ile bağlantılı olduğunu gösterir. Bu, statik bağlayıcıya, tanımlanmamış semboller için herhangi bir hata vermemesini, bunun yerine dinamik bağlayıcının çalışma zamanında sembolleri çözmeyi denemesini söyler. Bu nadiren istediğin davranış.
