Failing to build with 5.15.5 on Windows 10

JRoperMedtronic

Hello

I'm fairly new to QT and have been working on building an application in 5.15.5 that has previously been working with 5.8. After fixing a few blockers with the build, I hard-coded the path for IDLXMLGEN to the dynamic directory (C:\Program Files\Qt\Qt5.15.5\5.15.5\msvc2019_64) in order to get from 99 errors down to 1 (LNK errors)

Now that I've zero-d in on the error that's preventing this particular application to build (it has dependencies on QT as well as our greater project). Looks like MSBuild is looking for a file that doesn't exist in this directory.

"c:\t\ourproject.sln" (default target) (1) ->
"c:\t\ALL_BUILD.vcxproj.metaproj" (default target) (2) ->
"c:\t\library\OurAppDir\OurApp.vcxproj.metaproj" (default target) (638) ->
"c:\t\library\OurAppDir\OurApp.vcxproj" (default target) (639) ->
(Link target) ->
  **LINK : fatal error LNK1181: cannot open input file 'C:\Qt\Static\qtbase\lib\Qt5MultimediaQuick_p.lib'** [c:\t\library\OurAppDir\OurApp.vcxproj]

    20 Warning(s)
    1 Error(s)

The lib it's looking for doesn't exist in either the static or the dynamic directory.

I read a suggestion to add an OBJECTS_DIR entry to the "pro" file but I don't know if we are building that or where it would be found. Pardon my ignorance.

Thanks in advance

As a logical next step, I tried replacing the reference to the Qt5MultimediaQuick_p with Qt5MultimediaQuick, which brings up a new error. Interestingly, the same error comes up if I remove the reference altogether:

LINK : fatal error LNK1181: cannot open input file 'C:\Qt\Static\qtbase\lib\preprocessor.lib' [c:\t\library\translation\translation_tool.vcxproj]

Am I missing something here? This seems like a core library

Removing the reference to preprocessor.lib brings up an error on qtpcre.lib.

Removing the reference to that file brings up an error on translator.lib

If I remove that one, it opens the floodgates and gives me 1989 errors.. which is interestingly 1 less than a number of errors I had a few days ago as I've been debugging this.

Hope this helps..

Since 5.15.5 is a commercial version you should ask the Qt support for help.
