hg tag 0.8.0 fails to run on Ubuntu 20.04.6 LTS
Closed this issue · 4 comments
Pulling the latest source code or 0.8.0 tag and running ./configure with no arguments, then make or make njs produces an unusable binary. However, the issue is not present on 0.7.12 or 0.7.11.

Looks like this is caused when libreadline-dev is not installed. Not an issue with code. Feel free to close this.
I think we can still provide a better UX rather than a cryptic error message

Since 0.8.0 the support for libreadline was removed, instead the BSD variants are used now.
When no appropriate library is found njs CLI compiles, but without interactive shell support.
checking for editline library in editline/readline.h ... not found

- njs CLI is built without interactive shell support
Can you please share the configure log? In the configure log we should see the exact library that was used.

Do you have any ideas on how we can improve the current message?
