Depois que eu descobri meu Ubuntu 12.10 amd64 com 3.5.X Kernel não preenche algumas filas, e eles corrigiram isso no kernel 3.8.x, eu atualizei o kernel do meu Ubuntu para v3.10-saucy com a instalação do deb arquivos do kernel principal arquivo e as coisas correram bem.
uname -r
3.10.0-031000-generic
E o
sudo apt-get install linux-image-3.10.0-031000-generic
diz-me as coisas já instaladas.
Mas depois que eu compilei meu código C com o gcc, ele ainda afirma que o pedaço de código que supostamente funciona em & gt; 3.8.x, não é declarado!
O problema é que o novo cabeçalho do kernel instalado está em
/usr/src/linux-headers-3.10.0-031000-generic/include/
mas /usr/include ainda mantém os cabeçalhos antigos. O Gcc ainda lê de / usr / include para arquivos de cabeçalho.
Então eu vim com isso:
gcc --verbose -I /usr/src/linux-headers-3.10.0-031000-generic/include/ -o test.out test.c

compilation terminated.
Então, eu fiz:
gcc -nostdinc -I /usr/src/linux-headers-3.10.0-031000-generic/include/
para não permitir que o gcc acesse /usr/include . Mas ele afirma novamente que alguns arquivos incluem <net/if.h> not found e, removendo os arquivos de cabeçalho, ele também fornece alguma outra porcaria não encontrada dentro dos arquivos incluídos.
Se <net/if.h> estiver relacionado à biblioteca c, pode estar certo, porque faça o gcc não ler outras pastas de inclusão.
Mas relata alguns não encontrados dentro
<linux/if_tun.h>

Então, como eu suponho superar isso?
