This patch moves the base library from src/base to src/lib/base, flattens the library-internal directory structure, and moves the common parts of the library-description files to base/lib/mk/base.inc and base/lib/mk/base-common.inc. Furthermore, the patch fixes a few cosmetic issues (whitespace and comments only) that I encountered while browsing the result. Fixes #1952
This directory contains library description files. Each '<libname>.mk' file holds the instruction for building the library '<libname>'. These makefiles are never used directly but they are called from the build system when required. When called, the build system passes the following variables: :'BASE_DIR': This is the base directory of the source tree. Source codes are specified by setting the 'SRC_CC' and 'SRC_C' variables. The source code locations must be specified via 'vpath'. A library can include other libraries by setting the 'LIBS' variable. Each '<libname>.mk' file must include the 'lib.mk' role file: ! include $(BASE_DIR)/mk/lib.mk Libraries implementing one and the same library interface may have specific implementations for different platforms. Such platform-specific '<libname>.mk' files should be placed into corresponding subdirectories. For example, the 'linux'-specific implementation of the 'server' library resides in the 'linux/' subdirectory. The build system automatically searches the right '<libname>.mk' file by evaluating the 'SPECS' configuration variable. If 'SPECS' is set to 'host linux', the build system will look into the directories './', './host', and './linux'.
