Works for me.
It would be useful if you pasted an error message.

➜ ./vc -o v .
[1] 22369 segmentation fault (core dumped) ./vc -o v .
And with the repl:
➜ ./vc
V 0.0.12
Use Ctrl-D to exit
For now you have to use println() to print values, this will be fixed soon
>>> a := 9
>>> println(a)
[1] 22594 segmentation fault (core dumped) ./vc

you need clang, not gcc

@mint-xoxo you're trying to compile html, try downloading v.c again.

For me, it fails with both clang and cc in ArchLinux also.

Well now when i try and run ./vc -o v . it seg fualts

@mint-xoxo did you compile it with clang instead of cc?
CryZe

The README was old because I had to destroy the git repo. It's been updated now.
You need to have v directory in ~/code/.

@mint-xoxo well you need to, gcc doesn't work
CryZe
on 22 Jun 2019
I think a build script and including v.c in the repo might reduce these issues

use clang

@NotNite whats the output
nico-abram
on 22 Jun 2019
the error Segmentation fault: 11 is probably related to out of the stack loop.

In this situation, /var/tmp/vlang0.0.12 dir is not created so I make this dir but below that happend.

V panic: "/home/potatogim//code/v//builtin/array.v" doesnt exist
can't compile most examples.

ls() couldnt open dir "/home/djazz//code/v//gl"

V panic: /home/djazz//code/v//gl doesnt exist
The real question is, does tetris compile

@daniel-j we need to read this section again :)

mkdir /var/tmp/vlang0.0.12/
@daniel-j this helped, kinda, but:
$ ./vc -o v . && echo ok || echo fail
ok
$ ls
cgen.v fn.v jsgen.v main.v parser.v scanner.v table.v token.v vc v.c
Where is v binary?

It actually creates /var/tmp/vlang0.0.12/v.c, same with repl.
ln -s `which gcc` ~/.local/bin/clang
Solution for me, lol.
Clang hard coded everywhere:
~/code/v/compiler$ grep -r clang .
./main.v: // Find clang executable
./main.v: fast_clang := '/usr/local/Cellar/llvm/8.0.0/bin/clang'
./main.v: cmd := if os.file_exists(fast_clang) {
./main.v: '$fast_clang -I. $args'
./main.v: 'clang -I. $args'
./main.v: panic('clang error')
./v.c: string fast_clang = tos2("/usr/local/Cellar/llvm/8.0.0/bin/clang");
./v.c: string cmd = (os__file_exists(fast_clang))
./v.c: ? (_STR("%.*s -I. %.*s", fast_clang.len, fast_clang.str,
./v.c: : (_STR("clang -I. %.*s", args.len, args.str));
./v.c: v_panic(tos2("clang error"));
./cgen.v: // os.system('clang-format -i $g.out_path')
Binary file ./v matches
Binary file ./vc matches
./vc -o v .
does not produces any output here (to console of new file). ElementaryOS Juno.

Both packages on AUR are broken too.
https://aur.archlinux.org/packages/vlang
https://aur.archlinux.org/packages/vlang-git
Same issues reported previous in this thread.

@megatux see my comment above.
fix: ln -s `which gcc` ~/.local/bin/clang

I also encountered same issue on Arch Linux. I just added the following line into v.c due tostrerror requires string.h (but clang does not requires it):
#include <string.h>

First get it works, use clang -w -o vc v.c works for me, gcc not. ArchLinux too.

Should be fixed with v0.1.0, can you check?

Fixed on my machine, compiles fine on Arch Linux. Closing.
