Re: [Sdcc-user] FAQ...

[Gary M. <Gar...@st...>]

With the Borland C version of SDC V2.21, a default path for include files and
library files is hard coded into the search path for these type of files,
however the documentation I have seen gives the wrong default installation
path. In order to use the default paths you have to have a directory /sdcc
directly in the root directory of the C drive. Off the top of my head I can't
remember the necessary directories beneath /sdcc.

I would like to see support added for two new environmental variables. These
would allow the user to define a default include and library directory. Under
DOS (or even Cygwin) these are easy to setup. This would remove the need to
either hard code paths into the SDCC source code, and remove the need to follow
the directory structure currently imposed. Of course you can use the -I and -L
switches on the command line (or in a makefile), but that's too much for me to
type.
