the compiler was complaining that it needed
a program called lex
a program called flex seems to be the same
thing
so i installed the program flex
with sudo apt-get install flex
and it solved that problem
but now when it tries to compile
it gives lots of undefined references

i noticed one of the lines mentions lex:
/home/tom/gbdk/sdcc/src/SDCCy.c:1986: undefined reference to `yylex'
could this be caused by missing library’s or is this just a bug in the
program i need to try and fix?
