I'm trying to get the Leptonica 1.68 to work with Qt 5.2.0 (vs2012) static libraries. So i decided to try out the static libraries first, i downloaded the following package leptonica-1.68-win32-lib-include-dirs.zip
And iclude it in my project like so:
LIBS += -L$$PWD\leptonica-1.68-win32-lib-include-dirs\lib -lliblept168-static-mtdll -lgiflib416-static-mtdll
I also use the opencv that i build myself using vc2012+cmake
LIBS += -L$$PWD\opencv\static_libs -llibjpegd -llibpngd -llibtiffd -lIlmImfd -llibjasperd -lopencv_calib3d246d -lopencv_contrib246d -lopencv_core246d -lopencv_features2d246d -lopencv_flann246d -lopencv_gpu246d -lopencv_highgui246d -lopencv_imgproc246d -lopencv_legacy246d -lopencv_ml246d -lopencv_nonfree246d -lopencv_objdetect246d -lopencv_photo246d -lopencv_stitching246d -lopencv_superres246d -lopencv_ts246d -lzlibd
Opencv is built with /MTd and leptonica is built with /MTd too (i assume it from the library name "static-mtdll")
My qt is built with the following configuration:
configure -static -debug-and-release -opensource -confirm-license -platform win
32-msvc2012 -mp -qt-sql-sqlite -plugin-sql-mysql -I C:\MYSQL\include -L C:\QT\lib -c++11 -no-opengl
-nomake tests -nomake examples -no-crt -qt-zlib -qt-libpng -qt-libjpeg
When i'm trying to build my application i get

If i build that project dynamically using non-static qt version and opencv non-static libraries everything works just fine. (i guess that would be /MD). So i assume that leptonica is compiled with /MD and i need to recomplie it with /MTd (static debug). Please help, or maybe provide a faq or solution for building leptonica using vc2012.
