Linker Description
The linker also creates a global symbol _ _SYSMEM_SIZE and assigns it a
value equal to the size of the heap. The default size is 1K words.
For more information about linking C code, see Section 7.17,
Linking C Code,
on page 7-67.
7.4.9
Alter the Library Search Algorithm (–l Option, –i Option, and C_DIR
Environment Variable)
Usually, when you want to specify a library as linker input, you simply enter the
library name as you would any other input filename; the linker looks for the
library in the current directory. For example, suppose the current directory
contains the library object.lib. Assume that this library defines symbols that are
referenced in the file file1.obj. This is how you link the files:
lnk500 file1.obj object.lib
If you want to use a library that is not in the current directory, use the –l
(lowercase L) linker option. The syntax for this option is:
–l
filename
The
filename is the name of an archive library; the space between –l and the
filename is optional.
You can augment the linker’s directory search algorithm by using the –i linker
option or the environment variable. The linker searches for object libraries in
the following order:
1) It searches directories named with the –i linker option.
2) It searches directories named with the environment variable C_DIR.
3) If C_DIR is not set, it searches directories named with the assembler’s
environment variable, A_DIR.
4) It searches the current directory.
