[Solved] Unable to reference external library

[reezeus]

Hello

I have an issue when I try to build my Qt app (within Qt creator, MVSC2013 compiler). I need to include the Bloomberg C++ API and I think this is what is the caused of my issue.
I have used the Qt tool to add the external library, and the following script has been generated in the .pro file:

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/API/APIv3/C++API/v3.8.18.1/lib/ -lblpapi3_64
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/API/APIv3/C++API/v3.8.18.1/lib/ -lblpapi3_64d
else:unix: LIBS += -L$$PWD/API/APIv3/C++API/v3.8.18.1/lib/ -lblpapi3_64

INCLUDEPATH += $$PWD/API/APIv3/C++API/v3.8.18.1/include
DEPENDPATH += $$PWD/API/APIv3/C++API/v3.8.18.1/include

But I have the following message in the "Issues tab" when I try to build the project (after running qmake):
LNK1104: cannot open file 'blpapi3_64d.lib'

Can you help me please?

I am using
LIBS = -L$${PWD}/../../bin/lib/
-llaunchy.qxt

and it worked. Maybe missing braces?

Hi,

Is your project located in a path with spaces ?

Hi slesa, SGaist

I have tried to add the LIBS manually before using LIBS += "libpath" but it didn't work so I decided to use the tool to be sure it is not a syntax error.
The project is not located in a path with spaces, so there's no need for braces.

Might be a silly question but, are you sure you have both debug and release libraries for blpapi3_64 ?

[reezeus]

Hi SGaist

Actually it is not that silly... ;)
I had only the release version, I deleted the link to the debug library (which was automatically added by the Qt tool, because I had ticked "Add 'd' for debug version") and now it works perfectly.
Thanks for your help :) Cheers
