"make install" after successful "make" seems to be rebuilding for hours

[Douglas_A_Scott]

I am building Qt 5.15.2 from source on MacOSX 11.6 as follows:

../qt5/configure -prefix /opt/local/Qt-5.15.2 -opensource -nomake examples -nomake tests
make -j8
make install

I am not building for development because it turns on -Wall, which causes the primary compile to fail. The configure was fine. The "make" ran successfully to completion. When I typed "make install", it began the build of what looks like everything over again! Absolutely nothing happened on the machine between the end of the "make" and the beginning of the "make install".

Why would it be doing this?

Thanks.

Hi,

Did you check the date/times of your files ?
Do you have your clock that is off ?
