We do not support 3rd party tools. Try to test with the tesseract command line tool. Use tesseract version 5.2.0. If the issue still exists with tesseract itself, provide the...

The CMake build should do what the Autotools build is doing: check for icu >=52.1 and refuse to build the training tools if this requirement is not met.

Thanks, Zdenko. I only looked at the MakeLists.txt located in the root directory. I forgot that there is another one in the training dir.

``` if(PKG_CONFIG_FOUND) pkg_check_modules(ICU REQUIRED IMPORTED_TARGET icu-uc icu-i18n) ``` There is no version check here.

>Plus [ICU 52.1](https://icu.unicode.org/download/52) was released 2013-10-09, so I really wonder if somebody is using older version than that... http://mirror.centos.org/centos/7.9.2009/os/x86_64/Packages/ `libicu-50.2-4.el7_7.i686.rpm`

You can try to build with autotools instead of CMake. GCC 4.8 is not supported in Tesseract 5.x. RHEL/Centos have newer GCC versions in their repos: http://mirror.centos.org/centos/7.9.2009/sclo/x86_64/rh/Packages/d/ So you can...

Do you plan to train your own model using Tesseract? If not, ICU, Pango and Cairo are not required. [Autotools: Pango, Cairo and ICU only required by training tools](https://github.com/tesseract-ocr/tesseract/commit/502ebe8ca9524a6e9254371567b15e3ab1d76378) I...
