Not able to install 5.0.0 on ubuntu-trusty

[robertleelittleiii]

I added the PPA, but when I do an apt-get install tesseract-ocr, I still get the 4.1.1 version.

apt-cache policy tesseract-ocr
tesseract-ocr:

Did you run apt update?

[robertleelittleiii]

Yes.

Hi.
Tesseract version 5.0.0 not building on Ubuntu 14.04 :(

[robertleelittleiii]

Thanks, I just figured that out. Any idea what the issue is? Is it possible??

@stweil
Is it possible to fix this build error?

It might be possible to fix that (perhaps a backported newer GNU compiler or clang has better C++11 compatibility and works), but I don't think that we should spend time on old releases which are no longer supported. Ubuntu 14.04.6 LTS was supported until April 2019.

Thanks for the feedback. I was able to install Gcc-5 and G++-5 on Ubuntu and got it to compile and install.

Installing gcc 5 on ubuntu 14.04:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-5 g++-5

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5

I had to manually sym link g++-5 to g++, but after I did that it compiled without any issue.

That's not needed if you explicitly add the compiler during the configuration: ./configure CXX=g++-5 ...

[robertleelittleiii]

Good point. Thanks again for your help!
