I am trying to create a parallel application in C++ and I chose to use the Intel Cilk-Plus Libraries for this reason.

My problem is just that I am still trying to download the extension for g++ and compile it on my machine, but this thing is taking ages. As explained in the Intel Cilk Library installation doc, I am trying to get the compiler sources to compile them. I am actually trying to go for the GCC 4.9 release.

Trying SVN...

I did try using svn but this is very slow and many times the program fails and forces me to restart from where it broke.

Trying GIT...

When I try git it is even worse. The command executes but the program fails telling me that there is ome broken stuff on server side... Guess their git repository is not well-formed.

Bruteforse: WGET

So I decided to cut the head to the chicken and have a direct recursive download using wget:

wget -r -l 0 -np --erobots=off http://gcc.gnu.org/svn/gcc/branches/cilkplus/

It has been downloading since yesterday... I there a damn tarball to download or I really need to download using wget without any progress info? Thankyou

  • Did you try with `git` as well? – Adri C.S. Oct 03 '13 at 14:49
  • Git is broken... I mean the repository on their server is not well cofigured or something 'cause it always fails upon request... I mean it does not even start downloading, it rejects my request! – Andry Oct 03 '13 at 14:52
  • `ruby <(curl -fsSkL http://gcc.gnu.org/svn/gcc/branches/cilkplus/)` ? – Thomas Ayoub Oct 03 '13 at 15:01
  • Sad to hear. I usually prefer to fetch the sources with `git`. I tried method 3 and altough it took a few to generate the tar, the download was fast. – Adri C.S. Oct 03 '13 at 15:01
  • @AdriC.S.: Sorry could you please tell me more? You used method 3? You mean like me `wget`? – Andry Oct 03 '13 at 15:03

    No. In the install docs, there is a section labelled **a. cilkplus**. Under it there is a subsection labelled **iii. Using a snapshot**. I clicked on the link provided there. When the page is open, look for the first link. It should have a name like **[gcc/]** and next to it 3 colored tags. In that line, on the right corner there's is a link named **snapshot**. Click it and let's see if you get the tarball. – Adri C.S. Oct 03 '13 at 15:08
  • This question appears to be off-topic because it is not about C++ programming. – Pete Becker Oct 03 '13 at 15:08
  • Yeah I am removing the c++ tag probably it is not needed here. But no need to vote for closing, I still think this can be a useful question... – Andry Oct 03 '13 at 15:13

    @AdriC.S.: Believe me I could not find the iii option. Reloaded the page and it appeared!!!!! o_O – Andry Oct 03 '13 at 15:16
  • So, could you download the package? – Adri C.S. Oct 03 '13 at 15:17
  • Yeah I could find a tar... it is downloading it. Well, I guess this is it... Please post an answer, I'll check it! – Andry Oct 03 '13 at 15:18
  • Let's wait until you can confirm you have the right package. – Adri C.S. Oct 03 '13 at 15:19
  • Ok! Still downloading btw... – Andry Oct 03 '13 at 15:22

As asked by the OP, I'll post my comment as an answer.

To get the cilk-plus sources as a tarball:

  1. In the install docs, there is a section labelled a. cilkplus. Under it there is a subsection labelled iii. Using a snapshot.
  2. In that subsection there is a link to the gcc git repository. Click on it.
  3. When the webpage is loaded, search at the top for the first link. At the time of writing this it was named [gcc/]. However, the name may change. The link we need is the one with colored tags next to it.
  4. Once located search, in the same line, for a link named snapshot at the right corner.
  5. Click on it and wait while the tarball is generated.

NOTE: The link provided in the docs sometimes point to a rather old revision of the source code. To get the most recent one (1 or 2 days old at most) click on the summary section in the menu bar. There should appear an entry with the colored tags master and trunk next to it.
