Hello

I have been trying to build pynq image for Arty Z7-10 board over the weekend.  
I think the build fails when at making gcc, because the repository site is permanently shut down.

from gcc-mb/build.log we can see the following:

```auto
[ALL] --2021-11-28 23:41:44-- (try: 3) http://isl.gforge.inria.fr/isl-0.20.tar.gz
[ALL] Connecting to isl.gforge.inria.fr (isl.gforge.inria.fr)|128.93.193.15|:80... failed: Connection timed out.
[ALL] Giving up.
[ALL]    
[DEBUG] ==> Return status 4
[DEBUG] Not at this location: "http://isl.gforge.inria.fr/isl-0.20.tar.gz"
[ERROR] isl: download failed
[ERROR]  
[ERROR] >>
[ERROR] >> Build failed in step 'Retrieving needed toolchain components' tarballs'
[ERROR] >> called in step '(top-level)'

```

Has anybody else had these issues?  
How can I get around this? I am sure there are alternative repositories but how can I add them to the build?

Thanks for the help.

Replying to my own question in case somebody else has the same issue, since i wasted a lot of time on this.  
Tarballs are saved in /home/src/ folder. You can create folder manually and place any missing files there. The crosstool will not try download them if they are found.

PS  
I am analog and rf designer, not a software guy, so I don’t know how to force the process to use alternative repository. If someone else knows it I would be grateful for the explanation.

I had the same issue not too long ago.  
Here’s how I got over it: [Error During Creation of PYNQ SD Related to gcc-mb build - #2 by ATchelet](https://discuss.pynq.io/t/error-during-creation-of-pynq-sd-related-to-gcc-mb-build/3112/2)
