Hi  
I want to update the curl version to the latest 7.54.1. Firmware Packages - Release 14 have curl version 7.37.1 which do not support SFTP. If anyone done already please share the steps here.

below is the curl version details for Release14  
root@swi-mdm9x15:~# curl -V  
curl 7.37.1 (arm-poky-linux-gnueabi) libcurl/7.37.1 GnuTLS/3.3.5 zlib/1.2.8  
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smtp smtps telnet tftp

Hi,

One method would be to rebuild the rootfs with an updated curl recipe.  
If you add the content of [http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/recipes-support/curl](http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/recipes-support/curl) into `meta-swi/common/recipes-support` (or your own layer, up to you), you should be able to get an up-to-date curl.

Hi Roussel Thank you.  
i am able to build yocto with updated curl recipe but this do not come with all the protocol. Dont know how to include the protocol package.

i have removed PACKAGECONFIG ??= “${@bb.utils.filter(‘DISTRO\_FEATURES’, ‘ipv6’, d)} gnutls proxy zlib” from .bb file as i was getting ERROR during build (may be this is the reason)

See below what i am getting now

root@swi-mdm9x15:~# legato version  
16.10.3\_14a3a0c356102949b3a755b68e8ae60d\_modified  
root@swi-mdm9x15:~# curl -V  
curl 7.54.1 (arm-poky-linux-gnueabi) libcurl/7.54.1  
Release-Date: 2017-06-14  
**Protocols: file ftp http**  
Features: UnixSockets

To add `sftp` it seems that you will need `gnutls` support.  
To add `https` it would be `ssl` I think.

Could you try to add `ssl gnutls` in `DISTRO_FEATURES_DEFAULT` in the file `meta-swi-extras/common/conf/distro/poky-swi-ext.conf`.  
Cf [http://www.yoctoproject.org/docs/1.7.3/ref-manual/ref-manual.html#ref-features-distro](http://www.yoctoproject.org/docs/1.7.3/ref-manual/ref-manual.html#ref-features-distro) for some more info on this topic.
