cc1: avisos sendo tratados como erros ao compilar o FreeBSD 8.2 Release

Question

Eu estou tentando compilar o kernel do FreeBsd 8.2 RELEASE

# uname -a
FreeBSD 8.2-RELEASE FreeBSD 8.2-RELEASE #2: Sun May 18 00:07:10 PDT 2014

Construa o kernel

# pwd
/usr/src
# make buildkernel

... compila até eu receber este erro ...

Answer 1

Em ambos os casos, esses não são principalmente avisos que quebram a compilação.

Para a compilação do kernel:

error: 'struct run_vap' has no member named 'beacon_mbuf'

o compilador informa que o código está tentando acessar algo que não está lá. Isso pode ter muitas razões, mas geralmente sugere que o código está quebrado. Talvez você esteja tentando compilar um módulo que dependa de uma API interna mais nova / mais antiga do kernel (ou seja, está usando outra definição de estruturas do que o resto do kernel).

warning: passing argument 1 of 'm_freem' from incompatible pointer type

é frequentemente um erro de programação (ou seja, de fato, passar algo mais como argumento do que o esperado) ou um operador de elenco ausente.

cc1: warnings being treated as errors

é causado por -Werror nos sinalizadores do compilador, que informa ao compilador para tratar os avisos como erros. O que geralmente é uma boa ideia ^TM , na verdade (principalmente por causa das muitas vezes encontradas - "Mas compila, há apenas algumas advertências" atitude).

Para o outro problema:

csh.lo(.text+0xdba6): In function 'nlsclose':
: undefined reference to 'dl_iconv_close'

é na verdade um erro do link - a compilação foi (mais ou menos) bem, mas você não está fornecendo bibliotecas externas que fornecem alguns símbolos referenciados pelo código. Isso geralmente acontece quando você corretamente #include arquivos de cabeçalho e, em seguida, esquece de dizer linker para realmente vincular contra essa biblioteca (geralmente a opção -l ).
