Building on Centos 7: invalid conversion from ‘const Pix*’ to ‘Pix*’ about python-tesseract HOT 9 OPEN

Have u installed opencv?
https://gist.github.com/mitmul/9253702

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

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

could you send me a ssh account through my email?

Same issue here.

I have opencv installed and setup.py detects it just fine, but I am getting the 
same "no known conversion for argument 6 from ‘STRING*’ to 
‘tesseract::TessResultRenderer*’" error.  I added the flag "-fpermissive", 
still doesn't work.

Here's something that might point you in the right direction:

In tesseract_wrap.cpp, whenever the type of an argument should be 
tesseract::TessResultRenderer* instead of STRING*, just change the mention 
STRING* to tesseract::TessResultRenderer*.  Then I compiled using the following:

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -fPIC -I. 
-I/usr/local/include/tesseract -I/usr/local/include/leptonica 
-I/usr/include/python2.7 -c tesseract_wrap.cpp -o 
build/temp.linux-x86_64-2.7/tesseract_wrap.o -fpermissive -O0 -funroll-loops -g

and I didn't get any errors.  But the real problem is that tesseract_wrap.cpp 
was auto-generated by SWIG, so the bug must be in SWIG!

Don't use the svn version right now. 
zdenko makes some changes in the svn version which is a bit tricky to wrap
