Compilation de la référence non définie par apib au symbole 'pthread_create @@ GLIBC_2.2.5'
Je veux compiler apib sur ma boîte Ubuntu 13.04 mais j'ai des problèmes avec pthread lib. C'est l'erreur que je reçois:
$ colormake -j 5

Dans le Makefile:
APR_LIBS = -L/lib/x86_64-linux-gnu/ -lm -lcrypto -lpthread -lssl -lapr-1 -laprutil-1
OK, je l'ai trouvé - il y avait une erreur dans Makefile
APR_ONLY_LIBS n'avait pas de lien libthread:
APR_ONLY_LIBS = -lapr-1
Alors je l'ai changé pour:
APR_ONLY_LIBS = -lapr-1 -lpthread
