Description
I'm trying to build the Qt Webengine on Windows with MSVS 2022 (17.4.0) with conan and it keeps failing with this error:
Creating library qtbase\lib\Qt6WebEngineCored.lib and object qtbase\lib\Qt6WebEngineCored.exp
blink_core.lib(core_jumbo_225.obj) : error LNK2019: unresolved external symbol "public: void __cdecl blink::GraphicsContext::DrawTextW(class blink::Font const &,struct blink::TextRunPaintInfo const &,class blink::FloatPoint const &,class cc::PaintFlags const &,int)" (?DrawTextW@GraphicsContext@blink@@QEAAXAEBVFont@2@AEBUTextRunPaintInfo@2@AEBVFloatPoint@2@AEBVPaintFlags@cc@@H@Z) referenced in function "private: void __cdecl blink::SVGInlineTextBoxPainter::PaintText(struct blink::PaintInfo const &,class blink::TextRun &,struct blink::SVGTextFragment const &,int,int,class cc::PaintFlags const &)" (?PaintText@SVGInlineTextBoxPainter@blink@@AEAAXAEBUPaintInfo@2@AEAVTextRun@2@AEBUSVGTextFragment@2@HHAEBVPaintFlags@cc@@@Z)
qtbase\bin\Qt6WebEngineCored.dll : fatal error LNK1120: 1 unresolved externals
ninja: build stopped: subcommand failed.
I was not able to find a definition for `blink::GraphicsContext::DrawTextW`. I suspect what is going on is that the `#define DrawText DrawTextW` in `./qtwebengine/src/3rdparty/chromium/base/win/windows_types.h` are replacing `blink::GraphicsContext::DrawText` with ``blink::GraphicsContext::DrawTextW` from (`./3rdparty/chromium/third_party/blink/renderer/platform/graphics/graphics_context.h`) in certain situations
To reproduce, I use conan to build it.
Here's the command that I used:
conan install conanfile.py --build missing -s build_type=Debug --settings compiler.version=17 -s "compiler=Visual Studio"
and here's the `conanfile.py`:
