Hi Steve,
dm@fluke:/tmp$ g++ matrixtest.cc -I /usr/include/x86_64-linux-gnu/qt5 -msse2
-msse4.1 -fPIC -lQt5Core
dm@fluke:/tmp$ ./a.out
Hello
Hm.
Just to be sure, I also ran the attached executables, however they are giving
me the same result:
dm@fluke:/tmp$ ./test-sse4
Hello
dm@fluke:/tmp$ ./test-no-sse4
Hello
dm@fluke:/tmp$ g++ --version
g++ (Debian 13.2.0-1) 13.2.0
