Error: amberframework installation fails under crystal installed with asdf-crystal

[zenny]

Hi,

With crystal installed with asdf-crystal (https://github.com/marciogm/asdf-crystal) plugin, amber fails to build at 'shards install':

Dependencies are satisfied
Building: ameba
Error target ameba failed to compile:
/usr/bin/ld: cannot find -levent
collect2: error: ld returned 1 exit status
Error: execution of command failed with code: 1: `cc "${@}" -o '/DATA/zenny/Downloads/gitrepos/crystal-projects/amber-stable/lib/ameba/bin/ameba'  -rdynamic  -lyaml -lpcre -lm -lgc -lpthread /home/zenny/.asdf/installs/crystal/0.24.2/share/crystal/src/ext/libcrystal.a -levent -lrt -ldl -L/usr/lib -L/usr/local/lib`

Makefile:7: recipe for target 'build' failed
make: *** [build] Error 1

Even created a request to asdf-crystal developer to create a similar plugin at asdf-community/asdf-crystal#13.

Cheers,
/z

Hi @zenny

Try shards install --production and shards build -v

Then copy bin/amber to your /usr/local/bin path

I would guess this is a problem with the crystal asdf plugin. The error is here:

/usr/bin/ld: cannot find -levent which is a problem with how the Crystal dependency on libevent is specified.
