I need to compile a simple display image code in opencv on Ubuntu Linux platform but I am getting some errors as follows:
gcc: error: ‘pkg-config: No such file or directory
gcc: error: opencv‘: No such file or directory
gcc: error: unrecognized option ‘--cflags’
gcc: error: unrecognized option ‘--libs’
please can some one help me?
Please remember to include the command that's producing the error as well.
In this case I am guessing that you copy-pasted the gcc command line from somewhere and the punctuation got mangled
$ gcc -o hello ‘pkg-config --cflags --libs opencv‘ hello.cpp
gcc: error: ‘pkg-config: No such file or directory
gcc: error: opencv‘: No such file or directory
gcc: error: unrecognized option ‘--cflags’
gcc: error: unrecognized option ‘--libs’
The correct punctuation around the pkg-config string should be "backticks" not the forward ticks ‘ ... ‘ that you seem to have i.e.
$ gcc -o hello `pkg-config --cflags --libs opencv` hello.cpp
