libcurl.so.4 erro de referência indefinido

Question

Mesmo após a instalação do curl e de todos os pacotes libcurl em questão, como

curl libcurl3 libcurl3-gnutls
libcurl4-doc
libcurl4-nss-dev
libcurl-ocaml
libcurl3-dbg
libcurl3-nss
libcurl4-gnutls-dev
libcurl4-openssl-dev
libcurl-ocaml-dev

Eu recebo erros como

Qualquer ajuda apreciada

    

Answer 1

Parece que a libssl não contém mais símbolos iniciando SSLv3. Em vez disso, você deve compilar [insira o que quer que seja] contra o libgnutls-openssl.

Estou falando do ponto de vista de investigar por que o curl não irá vincular esse símbolo em tempo de execução no debian stable (jessie). Recompilar o curl adicionando alguns -lgnutls-openssl em CFLAGS nos Makefiles parece fazer o truque.

Suspeito de como a confusão acontece, mas pouca inclinação para interrogar alguém sobre isso!

    

Answer 2

O problema não é que há uma biblioteca _curl_ ausente, mas que libcurl.so.4 faz referência a funções de uma biblioteca que não é encontrada. Como se pode sugerir a partir dos nomes das funções ausentes, isso deve ser libssl .

Você pode investigar qual biblioteca exata está faltando usando ldd on libcurl.so :

$ ldd /usr/lib/x86_64-linux-gnu/libcurl.so.4

Ele reportará bibliotecas ausentes para você como

libssl.so.1.0.0 not found
