symbol-table

I am trying to build a symbol table from my grammar (done with antlr) by using eclipse. However I don't know by what to begin. I think I read somewhere that you would need the parser and lexer generated by antlr to do that. Does someone know an easy example so that I can understand how it works please ? A symbol table is just a versioned map of id's to values. This is one solution, using a push and pop of scopes as the versioning mechanism -- push a scope on entry of a scope defining rule and pop on exit. package net.certiv.metal.symbol; import java.util.ArrayList; import java.util

I'm writing an API as a kernel module that provides device drivers with various functions. I wrote three functions in mycode.c . I then built and loaded the module, then copied mycode.h into < kernel >/include/linux . In a device driver, I have a #include < linux/mycode.h > and call those three functions. But when I build the driver module, I get three linker warnings saying that those functions are undefined . Notes: The functions are declared extern in mycode.h The functions are exported using EXPORT_SYMBOL(func_name) in mycode.c Running the command nm mycode.ko shows all three functions as

Can someone describe what a symbol table is within the context of C and C++? There are two common and related meaning of symbol tables here. First, there's the symbol table in your object files. Usually, a C or C++ compiler compiles a single source file into an object file with a .obj or .o extension. This contains a collection of executable code and data that the linker can process into a working application or shared library. The object file has a data structure called a symbol table in it that maps the different items in the object file to names that the linker can understand. If you call a
