Alguém pode sugerir como resolver o problema

De link , versão 1.3.7 + dfsg-4 de torcs no Repos Debian contém o patch que corrige o erro de compilação que você está experimentando, alterando o ponteiro na linha problemática para apontar para um nullptr .

-   const char* error = '
-   const char* error = '%pre%';
+   const char* error = nullptr;
';
+   const char* error = nullptr;

O arquivo de patch completo está no link e na correção Introduz é plataforma neutra. Como alternativa, você pode compilar com -fpermissive como suas dicas de log.
