Issues with appending file while recursive walk

[AlexandrPutenikhin]

Hello,

I am writing a build script for my game engine. The script is split in 2 stages:

1. Compilation
2. Linking

The compilation stage is fine, but the linking has errors. It runs:

[INFO] CMD: cc -Wall -Wextra -o ../bin/gnost 'cc -Wall -Wextra -o ../bin/gnost ''
/usr/bin/ld: невозможно найти ��.G^: Нет такого файла или каталога
collect2: error: ld returned 1 exit status

But it should run:

[INFO] CMD: cc -Wall -Wextra -o ../bin/gnost ../obj/main.o

Here's the code:

#define OBJ_DIR "../obj"
#define BIN_DIR "../bin"

bool link_files(Nob_Walk_Entry entry) {
  if (entry.type == FILE_REGULAR) {
    Cmd* linkCmd = (Cmd*) entry.data;
    nob_cmd_append(linkCmd, entry.path);
  }
  return true;
}

Cmd cmd = {0};
nob_cmd_append(&cmd, "cc", "-Wall", "-Wextra", "-o", BIN_DIR"/gnost");
if (!nob_walk_dir(OBJ_DIR, link_files, .data = &cmd)) return 1;
if (!cmd_run(&cmd)) return 1;

iirc the lifetime of entry.path is very short and it dies when you exit the walk function. Consider strdup-ing it or something.
