Background

Over the past day I've updated several times.
Normally I got some tcc errors after I went to use after an update.
Doing an rm -rf /var/tmp/tcc/ after the issues would allow me to use v again.
Now (I've tried it several times), it won't update.

I understand this may be a duplicate, but I could not find this specific tcc error here.

I already had tcc installed on my system and was already using it. I removed it to see if these errors would go away, but they did not. (I've been using v less than 24 hours).

[spytheman]

For a temporary workaround, try:

export VFLAGS='-cc /your/working/bin/tcc'

or even simply

export VFLAGS='-cc tcc'

Please, do tell the result of locate crt1.o (the path is important, so that we can build a tcc that works on most distros).

[spytheman]

Also, thank you for the bug report.

[bogen85]

yeah, well, that update works (with the export)

however, when I go to use it, now I get:

182| if arr.cap == 0 {

183| arr.data = calloc(cap * arr.element_size)

         			   ^

184| }

185| else {

As far as my tcc:

$ pacman -Qs tcc local/tcc 0.9.27-3 Tiny C Compiler

and location of crt1.o

/usr/lib/Mcrt1.o /usr/lib/Scrt1.o /usr/lib/crt1.o /usr/lib/gcrt1.o /usr/lib/grcrt1.o /usr/lib/rcrt1.o /usr/lib32/Mcrt1.o /usr/lib32/Scrt1.o /usr/lib32/crt1.o /usr/lib32/gcrt1.o /usr/lib32/grcrt1.o /usr/lib32/rcrt1.o

If I export VFLAGS='-cc clang' then I get past that issue, but now I have other issues (array code that was working before is not working now), I'll see if there is another bug report for that.

Just to confirm, I also get similar issue on arch linux.

The output of running "make":

rm -rf vc/

[damontic]

As this was dependant on a pull request in https://github.com/vmisc/tccbin that was merged 40 minutes ago, it is not happening anymore in my Arch Linux machine. Please confirm @bogen85 @cloutiy

[cloutiy]

@damontic All seems fine for me now, thanks!

[medvednikov]

Huge thanks to @spytheman for fixing it!

What's your time v v.v? For me it's 0.25s :)

[bogen85]

@damontic it is fixed for me as well. Thanks!

[bogen85]

@medvednikov where is this supposed to be run?
time v compiler
V error: compiler doesn't exist!

[medvednikov]

@bogen85 v up

[bogen85]

@medvednikov alright... I'm in the directory v is cloned in...

@bogen85 the command changed:

I need to update the docs, thanks
