I'm trying to install Googles Tesseract OCR engine.
I have downloaded the source.
Extracted tar-gz with tar -xvzf

But when I run ./configure, I get this error:
checking for cl.exe... no
checking for g++... no
checking for c++ compiler default output file name...
configure: error: C++ compiler cannot create executables
See 'config.log' for more details.

Does anyone know how to get this to compile?
It's obviously something wrong with g++, but it is installed and working normally.

Same error occurs on the device and in scratchbox

Can you build the package on your regular desktop, outside scratchbox?

No.
The same problem.
Maybe it is a permission issue

I have tired to install it with apt from the extras rep.
It installs fine, but I'm having trouble running it.
So I was hoping someone could help me out.

I get the following error when I run tesseract command:
Error: Unable to open /home/opt/maemo/usr/share/tesseract-ocr/tessdata/eng.inttemp

I have searched, there are 2 instances of the file:
1. in /home/opt/maemo/usr/share/tesseract-ocr/tessdata/eng.inttemp, which is a symbolic link that point to itself.
Actually it points to /opt/maemo/usr/...
But since there is a symbolic link between /opt -> /home/opt, it points to itself.

2. the second one is in /media/n900/proc/self/root/proc/4705/cwd/tessdata (2)/eng.inttemp, but I doubt that this is the right one.

I can just copy the file from source over the link, but that is dirty.

Hi,

i've found the missing files on the google code project at the link below :
http://code.google.com/p/tesseract-o...ar.gz&can=2&q=

Before you need to delete the symlink from the destination directory. Then, you just have to extract and copy files into the /opt/maemo/usr/share/tesseract-ocr/tessdata/ directory.

Don't forget to change the privilege to 444 for all files.

Hope it will help.

edit test.cpp and whack in:

Code:
#include <iostream>

int main() {
  std::cout << "This works" << std::endl;
  return 0;
}
Then run

HTML Code:
g++ -o test test.cpp && ./test
can't create output is something I used to see a lot on solaris.. usually because solaris had a program with the same name as the C compiler.. it did nothing other then display "the c compiler is not installed"

weeeelll that is helpful!

Make sure your g++ compiler can actually produce working binaries first..

A Tesseract 3.0 package would be great...
