API Lief

**yann458** · 19/11/2025, 02h01

Bonjour,
Pour compiler les API Lief ,
Quand je fais cmake -DCMAKE_BUILD_TYPE=Release ..
et que je compile , c'est ok .
Quand je fais cmake -DLIEF_DEBUG_INFO=on -DLIEF_EXTENDED=on -DCMAKE_BUILD_TYPE=Debug -DCMAKE_MSVC_RUNTIME_LIBRARY=MultiThreadedDebug ..
ca compile , mais les exemples ne trouve pas les fonctions externes du .lib (lief.lib)

Comment faire ?

C'est pas des erreurs de compilation mais d'édition de lien.
Quand l'éditeur de lien cherche à intégrer le code binaire dans pdb_inspect.obj (provenant de la compilation de pdb_inspect.cpp) à l'exécutable finale, il lui manque tout un paquet de code binaire (venant de .obj ou de .lib) pour les fonctions indiquées dans les messages d'erreur.
Il manque donc très probablement un ou plusieurs .obj et/ou .lib en entrée de l'éditeur de lien.
Déterminez lesquels manque et les ajouter en entré de l'éditeur de lien, puis voir dans cmake ce qui manque pour que les entrés de l'éditeur de lien soient correctes.

Coucou bacelar,
Salut tout le monde,

J'ajouterais aussi que, généralement, il faut que la bibliothèque (.lib) et le projet soient compilés avec les mêmes options.
En effet, quand je lis par exemple LIEF_EXTENDED=on, je devine que c'est une macro qui va activer des fonctionnalités étendues, et que le projet va les utiliser. Cependant, si la lib a été compilée sans, elle en est dépourvue.
Bien sûr, c'est valable aussi pour le mode de construction "release" ou "debug", et dans le dernier cas, il a pu être ajouté un d à la fin du nom de la lib pour marquer la différence, genre liefd.lib, donc faire aussi attention à ça.
