Question

i want to use profile in Xcode to analyze a opencv programs,

and “Architectures” and “valid Architectures” is “x86_64”

but in got a message like:
“No architectures to compile for (ARCHS=ppc i386, VALID_ARCHS=x86_64).”

if i change “valid Architectures” to “x86_64 i386”,the functions in opencv can’t link

how can i do?

Answer 1

You simply need to build your OpenCV with the x86_64 architecture included as one of the architectures that’s compiled and linked into the OpenCV library.

Here’s a potentially useful tutorial on how to do this:
