Platforms

This command line application can be compiled on the following platforms:

  • Windows NT4, 2000, and XP with MSVC 6.0 SP3 or greater
  • x86 Linux 2.2 with gcc 2.95.2*
  • Macintosh OS X with Project Builder 2.1 and gcc 3.1

* If you are compiling with the binary distribution components (e.g. RealMedia file output or broadcast support) Helix DNA Producer must be compiled with gcc 2.95.x or earlier only. Binaries compiled with gcc 2.95.x are not compatible with later versions of the gcc compiler or any other compiler on Linux. This is due to a change made by gcc to be more compatible with other compilers (see gcc compiler documentation for details).

This command line application can be run on the following platforms:

  • Windows 98, ME, NT4, 2000, and XP
  • Linux 2.2, 2.4 with glibc 2.1 or greater
  • Macintosh OS X

Other applications and platform support may be added over time by various members of the Helix community, including RealNetworks.

** These components are only available to binary Licenses. To check out all components of the command line application or to check out the pre-compiled command line application, agree to the binary EULA here.
