Building on Centos 7: invalid conversion from ‘const Pix*’ to ‘Pix*’ #63

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

1. Followed the Centos 6.3 instructions in the wiki up to "python setup.py 
build".
3. That command gives several errors when running it on Centos 7 (CentOS Linux 
release 7.0.1406). See log output below.

$ sudo python setup.py build
Your os is:linux
..........
Current Version : 0.9
os=linux

Have u installed opencv?

Yes, I have built it from source as per the instructions in the wiki page as 
well as installing the RPM but I still get the error above. It seems to be 
built correctly.

But....

Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found

GoogleCodeExporter commented 9 years ago 
I have PKG_CONFIG_PATH="/usr/lib/pkgconfig" and 

$ ll /usr/lib/pkgconfig/

gives:

-rw-r--r--. 1 root root 951 Aug  4 22:38 opencv.pc
-rw-r--r--. 1 root root 466 Aug  4 23:21 tesseract.pc
