Thanks for trying.
I have the same error: "cannot find -llibzmq_d" and if I remove the _d
part, same thing... cannot find -llibzmq
error: ld returned 1 exist status collect2.exe
My .pro:
QT += core
QT -= gui
CONFIG += c++11
TARGET = hello
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
INCLUDEPATH += C:/zmq/include
INCLUDEPATH += C:/zmq/src
INCLUDEPATH += C:/zmq/bin
CONFIG(debug, debug|release) {
LIBS += -LC:/zmq/lib -llibzmq_d
}
CONFIG(release, debug|release) {
LIBS += -LC:/zmq/lib -llibzmq
}
SOURCES += main.cpp \
guid.cpp
HEADERS += \
guid.h \
The folder with zmq install:
C:\zmq
with bin, doc, include, lib, src... subfolders.
I copied all the dll in c:\zmq\lib and I have:
I also copied all the dll in the debug folder where the app execute...
libzmq-v90-mt-4_0_4.lib (and .dll and .pdb)
libzmq-v90-mt-gd-4_0_4.lib
libzmq-v100-mt-gd_4_0_4.lib
etc... for v110 and v120
