Galera, estou com um problema na instalação do squid para bloqueios de https, quando vou dar o comando "MAKE" me retorna o seguinte erro:

Parece q a opção de checagem gerou alerta na função strncpy e como está configurado p tratar alerta como erro (all warnings being treated as errors), parou a compilação. Acho q a soluçao é editar o Makefile.
Aqui um texto interessante sobre isso

Obrigado.

Você está recebendo uma aviso "-Werror=stringop-truncation" sobre um mau uso de função no código da smblib, como o seu make está configurado para tratar avisos como erro, ele se recusa a compilar.
É possível configurar o make para ignorar os warnings e talvez isso faça o código compilar, mas não sei se a smblib vai funcionar perfeitamente.

Acredito que se mudar o parametro do compilador de "-Werror=stringop-truncation" para apenas "-w" o seu código deve compilar, isso de acordo com a documentação do GCC.
Deve ter uma linha do seu makefile onde ajusta exatamente isso, "Werror" é o que vc procura.

Mude para a versão mais recente 4.13, pois houve correção de muitos erros dessa versão que vc quer instalar, eu instalei a versão 4.13 e ocorreu tudo certo!
De uma olhada neste link : https://techexpert.tips/squid/install-squid-with-https-ssl-decryption-ubuntu-linux/
me ajudou e muito, aqui está funcionando bloquei de https pelo squid 4.13 transparente, com relatório de log, controle de mac de boa!
