Hi,

I have used command ```opkg install voxl-mapper``` and also used voxl-cross to deploy voxl-mapper to the VOXL-CAM. 
But I am getting the same error shown below.

```
voxl:/$ voxl-mapper
voxl-mapper: error while loading shared libraries: libgomp.so.1: cannot open shared object file: No such file or directory

```
How can I rectify this error. 

Thanks!

@Anubhav smells like a version mismatch problem. Can you also run Voxl-mapper with -d for more info?

I have tried running ```voxl-mapper -d``` but getting the same error. I can also see there is no config file of voxl-mapper. 
The output is shown below for ```voxl-mapper -d```.

```
voxl:/$ voxl-mapper -d
voxl-mapper: error while loading shared libraries: libgomp.so.1: cannot open shared object file: No such file or directory

```

Hey @Anubhav,

Please see this post: https://forum.modalai.com/topic/1194/voxl-mapper-does-not-run-libgomp-so-1-does-not-exist/2?_=1662480745141.

You can also try out the latest improvements by switching opkg to the dev repo and reinstalling voxl-mapper.

@Matt-Turi Just out of curiosity, when will voxl-mapper have another stable release? Seems like a lot of exciting development is going on! :blush: 

Unfortunately with the dev branch I can get it running but it just outputs a white screen :cry:

The stable branch works great though so that has been fun! Excited for what is to come!

Hey @jamiek,

I can't give an exact timeline on the next stable voxl-mapper release, but it should be coming very soon with a lot of major improvements!

The dev release for mapper does require the dev versions of its dependencies as well, including voxl-portal and voxl-vision-px4 so that may be why you are hitting a white screen with that version.
