Building and using the LibHaru (v2.3.0-RC3) library

I'm trying to build and use libharu (v2.3.0-RC3) library in order to create PDFs. My spec (Windows 7, Qt 5.9.1, Qt Creator 4.3.1, CMake 3.9.0 - rc5, GNU Make 3.82.90)

I do it this way

• download from the official site enter link description here
• unzip "C:\Qt\Projects\libharu\libharu"
• mkdir libharu_build
• cd libharu_build
• cmake -G "MinGW Makefiles" -DCMAKE_INCLUDE_PATH="C:\gnuwin32\include\" -DCMAKE_LIBRARY_PATH="C:\gnuwin32\lib\" -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=Release ..\
• mingw32-make
• assembly result:"C:\Qt\Projects\libharu\libharu\libharu_build\src\libhpdf.dll"-"C:\Qt\Projects\libharu\libharu\libharu_build\include\hpdf_config.h"
• in Qt project (.pro file) INCLUDEPATH += C:\Qt\Projects\libharu\libharu\include \ C:\Qt\Projects\libharu\libharu\libharu_build\include LIBS += -LC:\Qt\Projects\libharu\libharu\libharu_build\src -lhpdf
• in Qt project (main file) #include "hpdf.h"
• when compiling a project, messages appear - undefined reference to HPDF_Page_BeginText - undefined reference to HPDF_Page_LineTo - undefined reference to HPDF_Page_Stroke - undefined reference to HPDF_Page_MoveTo

Command-line output during assembly:

C:\Qt\Projects\libharu\libharu\libharu_build>cmake -G "MinGW Makefiles" -DCMAKE_INCLUDE_PATH="C:\gnuwin32\include" -DCMAKE_LIBRARY_PATH="C:\gnuwin32\lib\" -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=Release ..\

If in a file "hpdf.h" remove lines, project is building. Functionality does not work.

//#ifdef HPDF_DLL_MAKE
#    define HPDF_EXPORT(A)  __declspec(dllexport) A  __stdcall
//#else
//#    ifdef HPDF_DLL_MAKE_CDECL
//#        define HPDF_EXPORT(A)  __declspec(dllexport) A
//#    else
//#        ifdef HPDF_SHARED_MAKE
//#            define HPDF_EXPORT(A)  extern A
//#        endif /* HPDF_SHARED_MAKE */
//#    endif /* HPDF_DLL_MAKE_CDECL */
//#endif /* HPDF_DLL_MAKE */

I will be grateful for your help!

It is necessary to connect libraries in this manner (in a file .pro):

LIBS += -LC:\Qt\Projects\libharu\libharu\libharu_build\src\ -lhpdfs
LIBS += -LC:\gnuwin32\lib\ -lz
