Hello,

I have a 7702 module running Legato for WP77 R9 - while I got a simple “hello world” component / app to run and debug just fine, the httpGet sample that comes as part of this package does not run - looking at device log, I see this message:

Jul 30 22:12:16 | supervisor[655]/supervisor T=main | app.c CreateFileLink() 1485 | Could not stat file at ‘/usr/lib/libgmp.so.10’. No such file or directory  
Jul 30 22:12:16 | supervisor[655]/supervisor T=main | app.c CreateFileLink() 1588 | Failed to create link at ‘/usr/lib/libgmp.so.10’ in app ‘httpGet’.

so it appears this file needs to be copied to my target device - should I report this issue as a bug?

Thanks!

I remember I tried on R8 and I need to modify the .adef file to be :

* * *

requires:  
{  
file:  
{  
// needed for curl itself:  
/usr/lib/libcrypto.so.1.0.2 /lib/libcrypto.so.1.0.2  
/etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/

```
    /usr/lib/libssl.so.1.0.2 /usr/lib/
    
    /usr/bin/curl /usr/bin/curl
    /usr/lib/libcurl.so.4 /usr/lib/

```
