GCC Linker ne peut pas localiser la bibliothèque

Question

J'essaie de compiler la bibliothèque PCRE dans un exécutable de test.

La documentation indique que l'exécution de Make, puis la configuration doivent générer la bibliothèque.

Dans le répertoire source PCRE:

Make 
./configure 
gcc -o test test.c -L . -lpcre 

Cependant, les retours d'erreur suivants:

/usr/bin/ld: cannot find -pcre 
collect2: error: ld returned 1 exit status 

Note: J'ai aussi essayé drapeau -libpcre. J'ai réussi à exécuter ceci sur MacOS (compilé séparément, mais le même code source de la bibliothèque et le même code source de test).

Answer 1

Essayez -lpcre pas -libpcre lorsque vous liez. -l prend le préfixe lib et prend le nom de la lib pour que -lpcre recherche libpcre
