I recently ran into some issues installingdiesel_cli on openSUSE. I wanted to use the package withpostgres only so I tried entering the following command from their getting started page:

# The package that is required according to the docszypperinstalllibpq5cargoinstalldiesel_cli--no-default-features--features postgres

Then I get met with this fun error message:

The last few lines are of interest:

= note: /usr/lib64/gcc/x86_64-suse-linux/13/../../../../x86_64-suse-linux/bin/ld: cannot find-lpq: No such file or directory          collect2: error: ld returned 1exitstatus

I started just installing all packages that I could find usingzypper search that related to postgres and tried the installation process ofdiesel_cli after each one. Eventually, after much trial and error I found the missing package:

sudozypperinstallghc-postgresql-libpq-devel

After installing this I was able to builddiesel.
