[Geographiclib-users] linker error using libGeographic 9.7.2 with QT

[hdixon<hd...@bi...>]

Hi,
I am trying to build a QT app using the latest libGeographic library.
I have used libGeoGraphic successfully with QT previously, but this
time I have a linker error which I cannot resolve.
I am wanting to convert eastings / northings to lat/ long using the
GeographicLib::GeoCoords class.


My linker output, from qt creator, is:
*************************************************************************
g++ -Wl,-rpath,/home/hugh/QtSDK-1.2.1/Desktop/Qt/4.8.1/gcc/lib -o

I have had trouble in the past with order of parameters in the call to
the linker, and am thinking there is something in libGeographic and QT
that conflicts or upsets.  

Does anyone have any experiance using libG with QT?  andif so have they
seen this problem and can you help please!

With thanks,
H
