Virtualbox Guest Addition: Erreur: la configuration du noyau n'est pas valide

Question

Ce que j'ai fait:

installer un minimum debian/test (pas d'interface graphique, pas de utilitaires standard)
installez la construction de Build-Essential, DKMS, Linux-Headers - $ (UNAME -R)
cliquez sur Périphériques -> Insérer un CD d'ajouts invités
a couru m-a prepare
mont /dev/sr0 quelque part, cd là et ./VBoxLinuxAdditions.run

Ce que j'ai:

... Building the modules for kernel 5.4.0-4-AMD64. Look at /var/log/vboxadd-setup.log to find out what went wrong. modprobe vboxsf failed ...

Qu'est-ce que c'est dans le journal:

... test -e include/generated/autoconf.h -a -e include/config /auto.conf || ( \ echo >&2; \ echo >&2 " ERROR: Kernel configuration is invalid."; \ echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\ echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \ echo >&2 ; \ /bin/false) ...

Ce que j'ai enquêté:

 $modprobe vboxsf modprobe: FATAL: Module vboxsf not found in directory /lib/modules/5.4.0-4-AMD $lsmod | grep vboxsf <no output> $find /usr/src/linux-headers-5.4.0-4-AMD64/ -name autoconf.h /usr/src/linux-headers-5.4.0-4-AMD64/include/generated/autoconf.h

L'OS hôte est Ubuntu 18.

Edit: Après avoir installé Openbox pour obtenir un serveur X, voici la façon dont le journal ressemble à:

Il semble y avoir un conflit entre les macros liées à l'attribut GCC fallthrough dans les pilotes d'addition d'invité de la boîte virtuelle et les en-têtes de noyau Linux.

Plus précisément, les pilotes de boîte virtuelle définissent plusieurs de ces macros comme suit:

root@vdebtest:/usr/src/vboxguest-5.1.38$ grep fallthrough -R vboxvideo/include/iprt/cdefs.h:# define RT_FALL_THROUGH() __attribute__((fallthrough)) vboxguest/include/iprt/cdefs.h:# define RT_FALL_THROUGH() __attribute__((fallthrough)) vboxsf/include/iprt/cdefs.h:# define RT_FALL_THROUGH() __attribute__((fallthrough))

Mais dans le noyau Linux à Inclure/Linux/compiler_attributes.h , il y a quelque chose comme ça:

/* * Add the pseudo keyword 'fallthrough' so case statement blocks * must end with any of these keywords: * break; * fallthrough; * goto <label>; * return [expression]; * * gcc: https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html#Statement-Attributes */ #if __has_attribute(__fallthrough__) # define fallthrough __attribute__((__fallthrough__)) #else # define fallthrough do {} while (0) /* fallthrough */ #endif

Maintenant, si je comprends bien votre journal de construction correctement, je pense que ces RT_FALL_THROUGH __s se retrouveraient en tant que __attribute__((__attribute__((__fallthrough__)))), en train de gâcher le code.

Pourriez-vous essayer d'entrer dans votre /usr/src/vboxguest-x.y.z dir et remplacer toutes les __attribute__((fallthrough)) (ce n'est que 3 de ceux de ma configuration) à __attribute__((__fallthrough__))? (Plain falthrough _ devrait aussi fonctionner, je suppose) ...

Puis reconstruisez tout cela par ./build_in_tmp.

Mise à jour : Je vois qu'il y avait des plaintes il y a quelque temps sur ce sujet ici . Et il semble avoir déjà été corrigé via ceci ticket .
