Requirements
    The following components are required to compile ClamAV under UNIX:
    2    
- zlib and zlib-devel packages
- openssl version 0.9.8 or higher and libssl-devel packages
- gcc compiler suite (tested with 2.9x, 3.x and 4.x series)
 If you are compiling with higher optimization levels
	      than the default one (-O2 for gcc), be aware that there
	      have been reports of misoptimizations. The build system of ClamAV
	      only checks for bugs affecting the default settings, it is your
	      responsibility to check that your compiler version doesn't
	      have any bugs.
- GNU make (gmake)
    
The following packages are optional but highly recommended:
- bzip2 and bzip2-devel library
- libxml2 and libxml2-dev library
- checkunit testing framework 3.
The following packages are optional, but required for bytecode JIT support:
    4
- GCC C and C++ compilers (minimum 4.1.3, recommended 4.3.4 or newer)
 the package for these compilers are usually called: gcc, g++, or gcc-c++.
	    5
- OSX Xcode versions prior to 5.0 use a g++ compiler frontend (llvm-gcc) that is not 
	    compatible with ClamAV JIT. It is recommended to either compile ClamAV JIT with 
	    clang++ or to compile ClamAV without JIT.
- A supported CPU for the JIT, either of: X86, X86-64, PowerPC, PowerPC64
    
The following packages are optional, but needed for the JIT unit tests:
- GNU Make (version 3.79, recommended 3.81)
- Python (version 2.5.4 or newer), for running the JIT unit tests
    
The following packages are optional, but required for clamsubmit:
- libcurl-devel library
- libjson-c-dev library
