Building warnings on openSUSE Tumbleweed

[Eiji7]

Hey, I just set up latest Erlang, but found 2 problems …

libopenssl-devel vs openssl-devel

WARNING: It appears a required development package 'openssl-devel' is not installed.

which comes from ~/.asdf/plugins/erlang/kerl (lines 370-388):

_rpm_is_installed() {
    rpm --quiet -q "$1" >/dev/null 2>&1
}

_check_rpm() {
    required='
openssl-devel
make
automake
autoconf
ncurses-devel
gcc
'
    for pkg in $required; do
        if ! _rpm_is_installed "$pkg"; then
            echo "WARNING: It appears a required development package '$pkg' is not installed."
        fi
    done
}

Let me show you my output:

$ rpm -q openssl-devel
pakiet openssl-devel nie jest zainstalowany
# message in Polish that such package is not installed
$ rpm -q libopenssl-devel
libopenssl-devel-1.1.1c-1.1.noarch

For some distributions there might be different package names which is really confusing for developers, but also such warning is really confusing to end-users.

The odbc application

The problem here is that I have installed all required packages i.e. libiodbc3, libltdl-devel (provided by libtool package) and unixODBC. Most probably I have missed something, but I was looking for it and of course tried to google it, but there are not much results for openSUSE.

That code you found that looks for openssl-devel is in https://github.com/kerl/kerl. asdf-erlang uses kerl underneath. It looks like it just checks for a list of packages, so it may take some work to get it working on OpenSUSE. I'm sure they would welcome the contribution over there though.

As for odbc, I'm not sure why it didn't find it. Did you install the equivalent of unixodbc-dev for your system?

@Stratus3D Thanks for your reply! I'm recompiling Erlang now, but I can already see that odbc is not in list of disabled applications. The problem was that in YaST Software Manager I have unchecked option: Show -devel packages F7 and I simply did not saw it. 😄

I will create an issue on project you have linked, so this one could be closed.
