Dependencies

The following is the current (as of December 27, 2006) list of direct dependencies for GNUstep.

Note :

• some of these dependencies are dependent of each other (e.g. tiff requires jpeg, and libungif requires freetype2)
• each of these dependencies may require additional libraries, which are not listed here
• the given names may not accurately reflect the actual package name as provided by your system

GNUstep-make

Required

• GCC with ObjC support -- preferably version 4.x
• GNU make -- called gmake or gnumake on some systems

Optional

• gdb -- for debugging
• Window Maker -- this would install a lot of dependencies beforehand

GNUstep-base

Required

• GNUstep-make
• libffi-dev (libffi) currently recommended default or ffcall -- stack-frame handling

Recommended development kit dependencies

• libxml2-dev (xml2) -- for XML-based property-lists
• libxslt1-dev (xslt) -- for style sheet support for use with XML
• libsssl-dev (openssl) -- for HTTPS connections in NSURL

The recommended and optional development kit packages in Debian and Ubuntu will pull in the compiled libraries for you as a dependancy. Selecting only the run-time library will generate a configure warning. If you continue with 'make', then the noted library functionalities will be missing in your final executable.

The remaining references give only the typical library name.

Optional

• libiconv -- Unicode support, only install if not provided by your system / glibc
