SIGILL, illegal instruction cvtps2pd

edit

Hi, I'm new to OpenCV and I'm giving it a try.

I had compiled OpenCV 2.4.7 source in an old AMD Athlon 2.2 Ghz machine with Ubuntu.

The examples don't work, I receive SIGILL, illegal instruction for instruction cvtps2pd .

Is this an issue with cmake or anything related in the building process?

I've followed the instructions from http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html

wich lead to:

cd ~/opencv mkdir release cd release cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local .. make sudo make install

Here is the stack from GDB and some info on the machine.
