ruby - gem install pg no se puede enlazar a libpq

postgresql ubuntu

Question

Después de actualizar a Ruby 1.9.3 (de 1.9.2 usando el sistema RVM) en Ubuntu 10.04.3, eliminé todas mis gemas e intenté reinstalar pg (ala bundle install pg ).

Luego arrojó un error y me informó que debería mirar mkmf.log, los cuales están incluidos en esta esencia: https://gist.github.com/d05a81701d968895c730

libpq-dev, libpq5 y postgresql-client están todos instalados y funcionando correctamente. La gema apuntando a pg_config, y los directorios include y bin directamente no parecen cambiar nada.

He visto varias preguntas sobre mensajes de error similares en stackoverflow y en el resto de la web, pero todas parecen ser simples problemas de dependencia faltantes (la mayoría de ellas se resuelven instalando libpq-dev), así que estoy un poco de una pérdida

Varias otras propiedades que pueden ser útiles / relevantes:

• ruby 1.9.3p0 (30/10/2011 revisión 33570) [i686-linux]
• rvm 1.10.1 (sistema)
• gema 1.8.15
• psql (PostgreSQL) 8.4.9

Gracias por adelantado.

Huele como un OpenSSL perdido. Tampoco veo un -lssl en la lista de la biblioteca, pero los símbolos que faltan sugieren que debería estar allí.

Intente instalar las bibliotecas de OpenSSL (versión 0.9.8 por el aspecto de las cosas). Luego vea si pg_config --libs contiene -lssl o similar y vuelva a intentarlo. Si todo esto funciona, es posible que desee enviar un informe de error a las personas de Ubuntu para que puedan corregir las dependencias de libpq-dev.

Lo siento, no tengo un Ubuntu configurado en cualquier lugar accesible en el momento, así que hay algunas conjeturas pasando aquí.

Answer 2

No se deje engañar por la lib de SSL que se está instalando, eche un vistazo a su compilación de Ruby y verifique el registro de compilación de SSL allí. He sido mordido por ese antes. Otras bibliotecas que a veces no se cargan son las de GZip. Este puede no ser el problema, pero echa un vistazo.

ACTUALIZAR:

Necesitas las bibliotecas -dev.

Estos días uso rbenv o alguna de las otras herramientas de construcción de ruby ​​y sigo los mensajes que escupieron.

Answer 3

Tengo el mismo problema en mi caso fue lib .rvm / usr / lib que fue llevado a esta compilación en lugar de lib del sistema. No estoy seguro de por qué sucede eso y por qué no funciona (en mi caso en Ubuntu 10.04 x86_64), pero para resolverlo simplemente:

 mv ~/.rvm/usr/lib ~/.rvm/usr/lib_rvm

por un tiempo o para siempre;)

Si alguien va a investigar por qué sucede, se lo agradeceré. Saludos.
