"https" not supported or disabled in libcurl

[hriapatil]

Hi, I tried compiling the packages and ran into the following error -

CMake Error at gflags_src-stamp/download-gflags_src.cmake:27 (message):
error: downloading 'https://github.com/gflags/gflags/archive/v2.1.2.zip'
failed

status_code: 1
status_string: "Unsupported protocol"
log: Protocol "https" not supported or disabled in libcurl

Closing connection -1

Any help is appreciated. Thanks!

Hi @hriapatil you might have an outdated version of curl. Can you please run: $ curl --version and give us the output?

Also this might be useful: https://askubuntu.com/questions/821186/protocol-https-not-supported-or-disabled-in-libcurl/821993

Hi @rdube , please find below the output of $ curl --version :

curl 7.35.0 (x86_64-pc-linux-gnu) libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3

This is probably not related to curl itself but to libcurl. More specifically to which version cmake is dynamically linked to. The following should shed some light on this question: ldd $(which cmake) | grep curl

This should yield the effectively linked .so file (=: YOUR_SO_FILE). After that you would still need to figure out what the library you found supports or even better how to upgrade it. On dpkg based systems (Debian, Ubuntu, ..) you can do the first with : dpkg -S <YOUR_SO_FILE>

I do not get any output from ldd $(which cmake) | grep curl

[HannesSommer]

Interesting! But we are getting closer. How did you get your cmake? Could it be that you compiled it from source? Of which distribution is your Linux? Could you maybe post the output of

• which cmake
• ldd $(which cmake)
• dpkg -S bin/cmake (in case your Linux is dpkg based)
• uname -a
• lsb_release -a

Thank you very much @HannesSommer for your generous support!

[hriapatil]

Thank you @HannesSommer and @rdube for your advice! I managed to solve the issue by reinstalling the libraries and ROS.

[rdube]

Good to hear that! Thank you for sharing your solution.

[HannesSommer]

Which were "the libraries" that you reinstalled? ROS should be irrelevant for this issue but reinstalling it might trigger some relevant library upgrade.

[hriapatil]

I actually reformatted my system. I believe there were many missing/corrupted links to various libraries.

[HannesSommer]

Ah, I see. Thanks for sharing.
