System requirements

The table below lists the software products which are necessary to support the complete functionality of the C library as they are provided with CRTE V10.0B00/V11.0B00 and described in this manual.

Product	Relevant components
BS2000/OSD-BC as of V10.0 or V11.0	Operating system Header files for POSIX functions
C/C++ as of V4.0	C and C++ compiler for POSIX subsystem and BS2000
CRTE V10.1A/V11.1A	Header files for BS2000 functions Runtime modules of the C library functions
POSIX-BC as of V10.0 or V11.0	POSIX file system Basic shell POSIX-HEADER V10.1A/ V11.1A
SDF-P	Variable structure SYSPOSIX for initializing the runtime environment

The commands of the POSIX subsystem, which includes two products, POSIX-BC and POSIX-SH, are described in the manual "POSIX Commands" [2 (Related publications)]. POSIX-SH commands increase the user ́s level of comfort when working in the POSIX shell but are not a system requirement for compiling, linking and starting C programs.
