I've managed do get gcc back to work (uninstalling / reinstalling), and ok, -DENABLE_SSE2=OFF made the trick for me.

Thank you so much Alexander!

make

Segmentation fault in program cc1

SegvAnalysis: Segfault happened at: 0x8957599: cmpw $0xb858,(%edx) PC (0x08957599) ok source "$0xb858" ok destination "(%edx)" (0x80000000) not located in a known VMA region (needed writable region)! SegvReason: writing unknown VMA SourcePackage: gcc-4.8 Title: cc1 crashed with SIGSEGV in __GI__IO_fwrite()

I have more trace but there are not enough space for them here :(

Is not cmake job to be aware of this in the build process? That bugs me.

But I'm going through a hell of a nightmare to build OpenCV in this machine. 'make' command breaks too often, giving me SEGFAULT and now I'm an not able to compile the source with your -DENABLE_SSE2=OFF suggestion.

I'll start all over again...

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.
