<RX14> String.build yields you an IO instance
<RX14> so you can use that
<RX14> however writing a raw integer to a string is unlikely to be what you want
<RX14> strings shouldn't contain binary data
<RX14> if you're working with binary data, IO::Memory and Bytes should be what you use
<hightower2> @RX14, right, was just about to say that, thanks
Never mind, I found it in
/usr/lib/gcc/x86_64-pc-linux-gnu/7.1.1/include, but clang seems to not be picking it up for some reason. I'm trying to use crystal_lib and it keeps telling me /usr/include/sys/types.h:145:10: fatal error: 'stddef.h' file not found
Would I do
$var_name : Float64?
long is, at least on most platforms that crystal targets, Int64
crystal doesn't have things like
unsigned, it's separate types, so UInt64
I'm gonna have an
always_ordered option that makes it use force ordered, otherwise I'm gonna use naive w/ reset
Good going using GitLab
I tried
fun numa_init, but it's telling me can't find function numa_init (Exception)
Oh well, I don't think it's an important one to include
So your code calls
Numa.init instead of an ugly, C-like name
Is it possible to wrap static functions? Like https://gitlab.com/procps-ng/procps/blob/master/proc/readproc.c#L89
crystal_lib seems to not like them
I had a little problem with my PC ... it died...
so, now, I am working on a brand new laptop
it has Fedora 26
and installed crystal
almost everything works... I just got that error when I tried the playground
the package lacks dependencies, probably. You should add the missing ssl lib
sudo dnf -y install openssl-devel may do the trick for you - check https://github.com/crystal-lang/crystal/wiki/All-required-libraries#fedora for more packages than you actually need
@watzon not really that sure about
static. May it be something with inline, instead?
