Mint 16 and Elementary OS installation issue

[x ray]

Hi Michael,

Here I am reproducing the message I left on your blob :

---
I tried to install version 1.1 on Linux Mint :

Distro: Linux Mint 17 Qiana
Operating System: Ubuntu 14.04.5 LTS
Kernel: Linux 3.13.0-24-generic
Architecture: x86_64

I followed the install steps (building/installig LLVM 3.3 and then crack 1.1).

Now I can do a

crack --version

but if I try to do crack hello.crk I get a

segmentation fault.

I want to use Crack for a serious project and I don't have the choice of the OS (Windows and Mint).

How can I help you ?

[x ray]

Here are the installation logs. Can you you tell if there is anything wrong ?

The procedure I have followed is the one on Git (INSTALL), except that I used "sudo make install" for both llvm and crack.

Can you send these either uncompressed or with a more common compression format (e.g. gzip, bzip, pkzip)?  It seems unlikely that there's anything odd going on in your install.

Two questions:

1) How much memory does your VM have configured? I've had problems with OOMing on 64-bit desktop-oriented systems with less than 1G of ram.

2) Can you please run "./crack_dbg -- hello.crk" from the root of the source directory, then enter "r" at the prompt (to run the program) and past the output?

The latter runs gdb, and will hopefully give us a little more information about exactly what's going wrong.

My virtual machine has  1987 MB of RAM.

crack_dbg  is not on the machine, It has apparently not been built.

I have joined the logs in a zip format and also the list of files I have in the crack-1.1 folder.

Ok, that should be fine.

Yeah, it's probably not in the distribution tarball.  Can you pull it from github?  You can either clone the repo at head:

  git clone https://github.com/crack-lang/crack.git

Or pull just the crack_dbg script from github:

   curl https://raw.githubusercontent.com/crack-lang/crack/master/crack_dbg >crack_dbg; chmod 755 crack_dbg

(once again, you'll want to do that from the root of the crack source tree -- it uses relative paths to the libraries) 

I have joined the logs in a zip format and also the list of files I have in the crack-1.1 folder.

What's interesting is that "crackdoc" seems to be working for you during install - that does a pretty good of exercising the program and a lot of libraries.  Does "crackc hello.crk" work for you?

[x ray]

I cannot find crackc either :(

As for the debug, I ran it after downloading the crack_dbg.  I hope it speaks to you :

Ok, you'll need to install libpcre3-dev to run the test suite.

Just following up on this for posterity: the problem was apparently due to
building on Clang, and potentially related to an existing version of LLVM that
was installed.

There's no reason why Crack shouldn't build under Clang, so I'll have to try
this out on my own.
