The following table shows all the third-party native dependencies used by LEADTOOLS. To determine which libraries require these dependencies, refer to the list at the end of this document. A table showing which LEADTOOLS library supports which features can be found here.
| Library | Description | Ubuntu Package Name | Fedora Package Name |
|---|---|---|---|
| uuid | Universally Unique Identifier library | uuid-dev | uuid-devel |
| uuid-runtime | uuidd | ||
| gcc | GNU compiler collection | gcc | gcc |
| g++ | GNU C++ compiler | g++ | gcc-c++ |
| glibc-devel | Standard C library | libc-dev-bin | glibc-devel |

| X11 | Core X11 protocol client library | libx11-6 | libX11 |
| libxt6 | libXt | ||
| X11-devel | Development files for libX11 | libx11-dev | libX11-devel |
| libxt-dev | libXt-devel | ||
| sqllite | C library that implements a SQL database engine | sqlite3 | sqlite |
| sqlite-devel | Development header files for sqlite | libsqlite-dev | sqlite-devel |
| freetype >= 2.3.8 | Font rendering engine | libfreetype6 | freetype |
| fontconfig >= 2.8.0 | Locates fonts within the system | fontconfig | fontconfig |
| Microsoft Core Fonts. See Notes below. | Microsoft True Type Core Fonts | ttf-mscorefonts-installer | See Installing Microsoft True Type Core Fonts below |
The following are the minimum versions required by the LEADTOOLS 23 toolkit:
| OS | Version |
|---|---|
| CentOS/Redhat | 7.9 |
| Fedora | 23 |
| Ubuntu | 16.04 |
| Debian | 9 |
Note
The LEADTOOLS OCR, Documents format readers, and Documents format writers modules will try to create fonts during their operation. If a needed font, such as "Arial" or "Times New Roman" is not found on the system, the module will substitute a different font. If an exact match for the module output between Windows and Linux is required, then the Microsoft Core Fonts component must be installed.
