Problems building #3
Description
I tried compiling this program at first just by running make. The Makefile failed to compile it, because GCC said there was a problem in the HOST macro:
<command-line>: error: ‘compiled’ undeclared here (not in a function)
version.c:3:12: note: in expansion of macro ‘HOST’
3 | char *host=HOST;
| ^~~~
<command-line>: error: expected ‘,’ or ‘;’ before ‘:’ token
version.c:3:12: note: in expansion of macro ‘HOST’
3 | char *host=HOST;
| ^~~~
<command-line>: error: stray ‘\’ in program
version.c:3:12: note: in expansion of macro ‘HOST’
3 | char *host=HOST;
| ^~~~
<command-line>: error: stray ‘\’ in program
version.c:3:12: note: in expansion of macro ‘HOST’
3 | char *host=HOST;
| ^~~~
I changed the flag to -DHOST="\"$(shell cat .host)\"" instead, and then that error went away. So, I tried again.
However, then I ran into a long list of linker errors (which I won't list unless you ask), entirely consisting of multiple definitions of global variables: hd, tl, files, current_file, tag, buf, and commandmode.
Am I doing something wrong when compiling, or does this program need to be updated so as not to have multiple definitions?
