Yesterday successfully cross compiled curl with mbedTLS, but there was an error when trying to access a https link:

1	SSL certificate problem: unable to get local issuer certificate

To fix it, download CA certificate to local machine and export environment variable CURL_CA_BUNDLE:

1 2	wget https://curl.haxx.se/ca/cacert.pem export CURL_CA_BUNDLE=<path of cacert.pem>
