cargo-update: Unable to install

First, I got an error that cmake was not installed. I installed cmake and then I get the following error

The only solution is updating system compiler (GCC in this case).

@perryprog I didn’t open an issue as I moved on to different system now.

@balkierode you may need to try upgrading GCC. GCC <= 4.4 only accepted the flag -std=gnu89, but support was later added (after 4.4) to support -std=gnu90. I can’t say that’s the primary error, but I believe that’s your main compiler errors when rust is building libssh2.
