Unsolved configure with -system-libjpeg fails
-
Hi
I am trying to configure and build qt with -system-libjpeg(libjpeg-turbo) on windows 10. One of my failing configure cmds is:C:\Qt\5.14.1\build_jpgturbo_msvc2017_64>..\Src\configure.bat -prefix ..\install_jpgturbo_msvc2017_64 -v -release -shared -platform win32-msvc -opensource -confirm-license -system-libjpeg -nomake tests -I "C:\_DEV_LIBS\C++\libjpeg-turbo\libjpeg-turbo64\include" -L "C:\_DEV_LIBS\C++\libjpeg-turbo\libjpeg-turbo64\lib"The configure process ends with error:
Image formats: GIF .................................. yes ICO .................................. yes JPEG ................................. yes Using system libjpeg ............... no PNG .................................. yes Using system libpng ................ no ERROR: Feature 'system-jpeg' was enabled, but the pre-condition 'features.jpeg && libs.libjpeg' failed.I have the latest vcpkg version, pearl and python installed. What else can I do to fix this error?
Thanks in advance

@solarisx You should check the configure.log file - it should provide more information about what exactly is the problem.

Thanks. Seems the libjpeg_turbo header and lib files are not found. I have the paths in the configure cmd. Did I specified them wrong?

in the configure.log are several fatal errors:
Notice: re-mapping requested qmake spec to unified 'win32-msvc'. ... > main.c > .\main.c(5): fatal error C1189: #error: __STDC_VERSION__ must be >= 199901L > NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX64\x64\cl.EXE"' : return code '0x2' ... > main.cpp > .\main.cpp(4): fatal error C1083: Cannot open include file: 'sys/socket.h': No such file or directory > NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX64\x64\cl.EXE"' : return code '0x2''sys/socket.h' is LINUX. How to specify the the Windows platform?
I use -platform win32-msvc and run the configure from the Visual Studio 2017 Developer Command Prompt on Windows 10.
Anything else to do? -
@solarisx said in configure with -system-libjpeg fails:
'sys/socket.h' is LINUX
I think you can ignore it - just one of many tests.
More interesting is "fatal error C1189: #error: STDC_VERSION must be >= 199901L" - which test is that? -

Ok. Found the problem. Thought using a 64bit command prompt results in a 64bit qt build. Now it works. Using x86 Native Command Prompt for VS 2017 as admin and 32bit libs of jpeg-turbo.
@jsulm thank you very much for your time.
