QT-yaratıcısı için x86_64 mimarisi için tanımlanmamış semboller

Question

Sadece C++ ile başlıyorum ve IDE olarak QT içerik oluşturucuyu nasıl kullanacağımı öğreniyorum, bu yüzden bunun gerçekten kolay olabileceğinden şüpheleniyorum ama bir şeyleri kaçırıyor olabilirim. Apollo MQ'yi kurdum ve apache CMS'yi (C++ messaging service) kurdum, böylece sunucuyla C++ arasında etkileşimde bulunabiliyorum. Sorun şu ki, yaptığım şey hakkında hiçbir fikrim yok :-) (henüz) ve örnekleri kullanırken yukarıdaki hatayı aldığımdan emin değilim.

Örneklerin iyi olduğundan eminim, çünkü bunlar kaynağın örnek klasörüne dahil edildiğinden, projenin yapılandırmasının doğru olmadığından şüphelenmeme neden oluyor (gerçekten de üzerinde etkisi olan tek şey olduğu gibi). İşte

drwxr-xr-x 13 root admin 442 May 11 19:09 activemq 
drwxr-xr-x 48 root admin 1632 May 11 19:09 cms 
drwxr-xr-x 9 root admin 306 May 11 19:09 decaf 

var: (istediğim dosyalar tüm alt dizinleri içindedir) İşte

TEMPLATE = app 
CONFIG += console 
CONFIG -= qt 

SOURCES += main.cpp 

INCLUDEPATH += /usr/local/include/activemq-cpp-3.4.2/ 
INCLUDEPATH += /opt/local/lib/ 

Ben işaret ediyorum klasör içeriği olan:

İşte .pro dosyasıdır hata:

Sadece boş C++ projesini yarattı, kütüphaneler için bir yol içerecek şekilde .pro dosyayı modifiye ve daha sonra kodu main.cpp'ye kopyalayın/yapıştırın. Bunun ne olduğu hakkında bir fikrin var mı? ve nasıl önleyebilirim?

Answer 1

kitaplık yollarını; INCLUDEPATH'u yeni değerlerle tanımlayın, ancak karşılık gelen bir LIBPATH veya LIBRARYPATH veya kitaplıklar için eşdeğerli değişken adı ne olursa olsun eklemeyin. Belirli kütüphaneler için ilgili -l library parametrelerine de ihtiyacınız olmayacak mı?
