Window下编译qtpdfium

Window下编译qtpdfium

系统环境：windows11

Qt版本：Qt5.15.2

源代码路径：​​d)#后面，添加下面代码if(CMAKE_COMPILER_IS_GNUCXX) set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS}") #设置编译C++文件时，使用c++11 message(STATUS "optional:-std=c++11")endif(CMAKE_COMPILER_IS_GNUCXX)IF (WIN32) MESSAGE(STATUS "Now is windows") add_compile_options(-shared -fPIC) ELSEIF (APPLE) MESSAGE(STATUS "Now is Apple systens.")ELSEIF (UNIX) MESSAGE(STATUS "Now is UNIX-like OS's. Including aPPLE os x and CygWin") add_compile_options(-std=c++11 -shared -fPIC) #linux下必须要添加编译选项-fPIC，要不然提示错误ENDIF ()

2.修改qpdf\src\3rdparty\CMakeLists.txt

#注释掉下面代码#if(MSVC)# list(APPEND PDFIUM_SOURCES# pdfium/core/fxge/win32/fx_win32_device.cpp# pdfium/core/fxge/win32/fx_win32_dib.cpp# pdfium/core/fxge/win32/fx_win32_dwrite.cpp# pdfium/core/fxge/win32/fx_win32_gdipext.cpp# pdfium/core/fxge/win32/fx_win32_print.cpp# )# list(APPEND PDFIUM_HEADERS# pdfium/core/fxge/win32/dwrite_int.h# pdfium/core/fxge/win32/win32_int.h# )#endif(MSVC)#添加下列代码IF (WIN32) add_definitions(-DCOMPILE_SAL_MINGW) #增加预编译宏，等下在代码修改里要用到 MESSAGE(STATUS "Now is windows") list(APPEND PDFIUM_SOURCES pdfium/core/fxge/win32/fx_win32_device.cpp pdfium/core/fxge/win32/fx_win32_dib.cpp pdfium/core/fxge/win32/fx_win32_dwrite.cpp pdfium/core/fxge/win32/fx_win32_gdipext.cpp pdfium/core/fxge/win32/fx_win32_print.cpp ) list(APPEND PDFIUM_HEADERS pdfium/core/fxge/win32/dwrite_int.h pdfium/core/fxge/win32/win32_int.h )ELSEIF (APPLE) MESSAGE(STATUS "Now is Apple systens.")ELSEIF (UNIX) MESSAGE(STATUS "Now is UNIX-like OS's. Including aPPLE os x and CygWin")ENDIF ()

3.修改代码：qpdf\src\3rdparty\pdfium\core\fxge\win32\fx_win32_dwrite.cpp

## 修改函数：HRESULT(__stdcall* FuncType_DWriteCreateFactory)为下面# 大概位置14行##ifdef COMPILE_SAL_MINGWtypedef HRESULT(__stdcall* FuncType_DWriteCreateFactory)( _In_ DWRITE_FACTORY_TYPE, _In_ REFIID, _Out_ IUnknown**);# elsetypedef HRESULT(__stdcall* FuncType_DWriteCreateFactory)( __in DWRITE_FACTORY_TYPE, __in REFIID, __out IUnknown**);#endif## 修改函数：HRESULT STDMETHODCALLTYPE DrawGlyphRun(const FX_RECT& text_bbox为下面# 大概位置120行##ifdef COMPILE_SAL_MINGW HRESULT STDMETHODCALLTYPE DrawGlyphRun(const FX_RECT& text_bbox, __in_opt CFX_ClipRgn* pClipRgn, __in_opt DWRITE_MATRIX const* pMatrix, FLOAT baselineOriginX, FLOAT baselineOriginY, DWRITE_MEASURING_MODE measuringMode, _In_ DWRITE_GLYPH_RUN const* glyphRun, const COLORREF& textColor);# else HRESULT STDMETHODCALLTYPE DrawGlyphRun(const FX_RECT& text_bbox, __in_opt CFX_ClipRgn* pClipRgn, __in_opt DWRITE_MATRIX const* pMatrix, FLOAT baselineOriginX, FLOAT baselineOriginY, DWRITE_MEASURING_MODE measuringMode, __in DWRITE_GLYPH_RUN const* glyphRun, const COLORREF& textColor);#endif## 修改函数：STDMETHODIMP CDwGdiTextRenderer::DrawGlyphRun(为下面# 大概位置431行##ifdef COMPILE_SAL_MINGWSTDMETHODIMP CDwGdiTextRenderer::DrawGlyphRun( const FX_RECT& text_bbox, __in_opt CFX_ClipRgn* pClipRgn, __in_opt DWRITE_MATRIX const* pMatrix, FLOAT baselineOriginX, FLOAT baselineOriginY, DWRITE_MEASURING_MODE measuringMode, _In_ DWRITE_GLYPH_RUN const* glyphRun, const COLORREF& textColor) {# elseSTDMETHODIMP CDwGdiTextRenderer::DrawGlyphRun( const FX_RECT& text_bbox, __in_opt CFX_ClipRgn* pClipRgn, __in_opt DWRITE_MATRIX const* pMatrix, FLOAT baselineOriginX, FLOAT baselineOriginY, DWRITE_MEASURING_MODE measuringMode, __in DWRITE_GLYPH_RUN const* glyphRun, const COLORREF& textColor) {#endif

4.修改代码qpdf_cmake\src\3rdparty\pdfium\core\fxge\win32\fx_win32_gdipext.cpp

# 694行m_Functions[i] = GetProcAddress(m_hModule, g_GdipFuncNames[i]);# 修改成m_Functions[i] = (void*)GetProcAddress(m_hModule, g_GdipFuncNames[i]);# 709行GetProcAddress(m_GdiModule, "AddFontMemResourceEx");# 修改成(void*)GetProcAddress(m_GdiModule, "AddFontMemResourceEx");# 711行GetProcAddress(m_GdiModule, "RemoveFontMemResourceEx");# 修改成(void*)GetProcAddress(m_GdiModule, "RemoveFontMemResourceEx");

修改完毕，可以执行run cmake,build,run，然后就可以打开pdf啦。
