Mysql gem: better native extension error than this?

Tony_Arcieri6 · 4 February 2010 00:38

uninitialized constant MysqlCompat::MysqlRes

...surely the error can be better than this. The meaning of this error is
"the native extension failed to load", however the error does not convey
this whatsoever. Can't this be:

NativeExtensionError: couldn't load libmysqlclient.so

Or something slightly more informative?

When are you getting this?

A sample script that can reproduce it? Or is a Rails application?

Definitely things could be better, also world peace can be achieved if
humans weren't so greedy and help each other instead.

The repository used to build the gem is here:

Feel free to fork it, adjust what is needed and ensure tests works
prior sending a pull request.

Regards,

When are you getting this?

is set.

The offending code is here:

github.com

luislavena/mysql-gem/blob/master/ext/mysql_api/extconf.rb#L1-8


# Darwin (OSX) special cases for universal binaries
# This is to avoid the lack of UB binaries for MySQL
ENV["RC_ARCHS"] = "" if RUBY_PLATFORM =~ /darwin/


require 'mkmf'


# Improved detection of mysql_config
# Code from DataObjects do_mysql adapter


# All instances of mysql_config on PATH ...
def mysql_config_paths

Since I haven't upgraded my Leopard installation to Slow Leopard, I
cannot test all these details.

I've that *cough* feature *cough* from DataObjects, which got removed
after SL release.

Since I don't have a spare Mac for work, couldn't afford the time will
take to rebuild my whole environment due the craziness of mixed 64/32
bits applications and libraries.

If you take a look to current DataObjects, maybe you can bring these
changes in:

github.com

datamapper/do/blob/master/do_mysql/ext/do_mysql/extconf.rb

ENV["RC_ARCHS"] = "" if RUBY_PLATFORM =~ /darwin/

require 'mkmf'
require 'date'

# Allow for custom compiler to be specified.
RbConfig::MAKEFILE_CONFIG['CC'] = ENV['CC'] if ENV['CC']

# All instances of mysql_config on PATH ...
def mysql_config_paths
  ENV['PATH'].split(File::PATH_SEPARATOR).collect do |path|
    [ "#{path}/mysql_config", "#{path}/mysql_config5" ].
      detect { |bin| File.exist?(bin) }
  end
end

# The first mysql_config binary on PATH ...
def default_mysql_config_path
  mysql_config_paths.compact.first
end
