Before installing ImageGear for C and C++ on Linux, make sure that your computer meets the minimum requirements detailed in this section.

• Intel based platform
• 4.4+ kernel
• GCC 4.8+ compiler
• GCC 4.9+ is needed when PDF component is used.
• GCC 9.4+ is needed when HEIF component is used.
• X11R6 include files & libraries
• Java JRE or OpenJDK version 8 or later (to run License Manager and Server Licensing Utility)

Note: PDF support requires GCC4.8 compiler with GLIBCXX 3.4.14.

Supported Operating Systems:

• CentOS 64-bit
• Red Hat Enterprise Linux 64-bit
• Ubuntu 64-bit

Note: ImageGear will also run on other Linux distributions, as long as those fully satisfy the requirements listed in this section.

Detailed requirements for libraries:

• libc.so.6
• libstdc++.so.6
• libm.so.6
• libpthread.so.0
• libgcc_s.so.1
• libX11.so.6
• libXau.so.6

Note: By default, C libraries are being built with thread local storage enabled. Please make sure to use such kind of libraries, i.e., they should be built without '--without-tls' compiler flag.

To install all required packages, do the following:

RMP package:
yum install gcc gcc-c++ libX11-devel

DEB package:
apt-get install g++ libx11-dev

To build/run GUI samples, additional packages are required:

• Motif 1.2 or later
• make
• cmake

To install them, do the following:

RPM package:
yum install libXt-devel libXext-devel libXp libXp-devel openmotif openmotif-devel make cmake

DEB package:
sudo apt-get install g++ make cmake build-essential libxm4 libmotif-dev libxext6 libxext-dev libxt-dev
