Eu tentei compilar o Python 3.6.0 e o CPython mais recente a partir de fontes em um modelo Debian dentro de Qubes OS (gcc 4.9.2).
Eu consegui fazer isso, mas procurando a saída configure em detalhes, eu notei que muitas bibliotecas e funções parecem não estar disponíveis e para algumas delas, o script de configuração deu uma resposta positiva para o syscall, mas negativo para a função, como por getrandom() :
...
checking for the Linux getrandom() syscall... yes
checking for the getrandom() function... no
...
Encontrei o código de teste usado em configure , compilado e testado por mim e funciona bem:
#include <unistd.h>
#include <sys/syscall.h>
#include <linux/random.h>
int main() {
const int flags = 0;
char buffer[1];
int n;
/* ignore the result, Python checks for ENOSYS at runtime */
(void)syscall(SYS_getrandom, buffer, sizeof(buffer), flags);
return 0;
}
Portanto, não consigo entender por que configure parece não gostar dessas funções. **
Outra coisa é que não é possível encontrar g++ , mas eu instalei e funciona bem:
checking for g++... no
configure:
By default, distutils will build C++ extension modules with "g++".
If this is not intended, then set CXX on the configure command line.
Eu estou vindo de Ubuntu , então eu gostaria de saber se este é um problema relativo a Debian , o Qubes OS Template para Debian ou um erro de configuração ou falta de componentes que eu possa resolver facilmente, continuar usando Debian dentro de Qubes OS .
