Problems building

[sebastian-davidson]

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?

Try the cmake build please.

Okay, so now I've done this:

$ mkdir build
$ cmake -G "Unix Makefiles" -S . -B build
$ cd build
$ make

It fails to build due to what looks like two errors in the file reduce.c:
