In particular ksh (the illumos /bin/sh), its +supporting libraries and and a small number of system commands, see +./ksh/builtins/alias.c + +The source for these components is in usr/src/contrib/ast/; see the README +file there for more information. + +The AST library builds use FEATURE files to describe the capabilities of the +host system and build environment (similar to the output from tools like +GNU autoconf). In order to support cross compilation and ensure reproducible +builds, these files are present in this tree under libXXX/<arch>/FEATURE/ +alongside a small number of other generated files. + +The FEATURE files can be re-generated based on the current contents of +proto using 'make _feature' in this directory. This should be done after +adding new features to the standard libraries that AST can detect and use. +This needs to be done for all supported architectures. |
