# # For a description of the syntax of this configuration file, # see misc/tools/kconfig-language.txt. # config INTERPRETERS_BAS bool "Basic Interpreter support" default n select SCHED_WAITPID select LIBC_EXECFUNCS depends on FS_READABLE ---help--- This is a Basic interpreter written by Michael Haardt NOTE: This interpreter requires a usable math.h header file. By default, the math library (and hence, math.h) are not provided by NuttX. Therefore, when the Basic code includes math.h it will either fail to find the math.h header file or, worse, will take an incompatible version of math.h from your toolchain. The toolchain's version of math.h will be incompatible because it will have been implemented to work with a different version of the C library. Normally, developers will use an optimized math library for their processor architecture and do the following: - Save a customized copy of math.h from your tool chain in nuttx/arch//include - Set CONFIG_ARCH_MATH_H=y in your .config file to select this architecture-specific math.h header file. An option is to use the built-in, generic, unoptimized NuttX math library that is selected by simply by: - Set CONFIG_LIBM=y in your .config file if INTERPRETERS_BAS config INTERPRETER_BAS_VERSION string "Version number" default "2.4" config INTERPRETER_BAS_USE_LR0 bool "LR0 parser" default n ---help--- Select if you want LR0 parser. config INTERPRETER_BAS_USE_SELECT bool "Use select()" default n endif
