macOS tab completion

[jamesapp]

james-collinss-macbook-pro:chap5 jamescollins$ gcc dcl.c -o dcl.out
i686-apple-darwin9-gcc-4.0.1: dcl.c: No such file or directory
i686-apple-darwin9-gcc-4.0.1: no input files

why does computer not recognize dcl.c?
i used tab completion on dcl.c and program compiled with following errors:

james-collinss-macbook-pro:chap5 jamescollins$ gcc dcl.c\ -o dcl.out
ld: warning in dcl.c , file is not of required architecture
Undefined symbols:
"_main", referenced from:
start in crt1.10.5.o
ld: symbol(s) not found
collect2: ld returned 1 exit status


here is my source file dcl.c

/* dcl: parse a declarator */
void dcl(void)

  int ns;
  
  for (ns = 0; gettoken() == '*'; )  /* count *'s */

just wondering why computer didn't recognize dcl.c, and why program didn't compile?

Looks to me...

...like dcl.c has a space after the '.c' in the filename.

As for the error message, well, try it without the space and see if it still happens.

Your source code is very unorthodox. You should put includes at the top of the file along with defines and any global data (although I tend to put them in header files for simplicities sake).

Have you just merged some source files into one?

 

[yeroen]

Your command line is wrong.

Type this:

gcc -g -o dlc dlc.c

main() also needs a return type of int

i had a space in the file name. i believe the space was causing problems, i also had other problems in the code.
