[resolved]A question about installation 4.7.0

cqbztzl · April 24, 2023, 6:08am

When I was compiling, Windows PowerShell provided feedback:

What can I do?

which mingw is it, exactly ? (g++ --version, please)
(you need a version, that supports posix threads,
else it does not have the resp. mutex headers)

also, just saying, since there is NO mingw containing MSMF
support code, you need to disable :

 WITH_MSMF=OFF    WITH_OBSSENSOR=OFF

and , maybe (idr) also disable hdf/exr support:

WITH_OPENEXR=OFF  BUILD_OPENEXR=OFF

Thank you.

It worked.

But now PowerShell provided feedback:

what worked ? still same error, no ?

cqbztzl · April 24, 2023, 9:45am

It seems like it is, but I see the progress has changed from 8 to 13.

Please forgive my ignorance

berak · April 24, 2023, 9:51am

most probably, bc you skipped a library (less work to do)

cqbztzl · April 24, 2023, 9:54am

I think you are right.

What else can I do?

berak · April 24, 2023, 10:11am

again, g++ --version, please
( imo you have to switch (dl, install) to a different compiler toolchain, e.g. this, again, you need 64bit, posix, seh support to build opencv )

cqbztzl · April 24, 2023, 11:05am

So,

This will not do.

Is this?

cqbztzl · April 24, 2023, 11:23am

You are right,and there are some changes.

But,somthing is also wrong.

clean build folder (from previous artifacts) & try again, starting with cmake, please

cqbztzl · April 24, 2023, 12:42pm

Thank you very much,it’s OK.

bwajster · April 30, 2023, 5:33am

Which version of MinGW did u use for 64bit OS , posix, seh support to build opencv library ? @cqbztzl

cqbztzl · April 30, 2023, 6:01am

This.

bwajster · April 30, 2023, 6:02am

Which version of OpenCV did you use ?

cqbztzl · April 30, 2023, 6:20am

In the title: opencv4.7.0
