Buildroot : Maybe you need to increase the filesystem size (fix)
I'm far from an expert regarding buildroot but I'm currently investigating it to build the second version of my jukebox for kids to have a faster system and the first thing I have encountered even with a default install is the following error message (French system):
mkfs.ext4: N'a pu allouer de bloc dans le système de fichiers ext2 lors du peuplement du système de fichier
*** Maybe you need to increase the filesystem size (BR2_TARGET_ROOTFS_EXT2_SIZE)
fs/ext2/ext2.mk:48 : la recette pour la cible « /home/nous/Bureau/br-tree/buildroot-2017.11.1/output/images/rootfs.ext2 » a échouée
make[1]: *** [/home/nous/Bureau/br-tree/buildroot-2017.11.1/output/images/rootfs.ext2] Erreur 1
Makefile:79 : la recette pour la cible « _all » a échouée
make: *** [_all] Erreur 2I have not been able to find much information about BR2_TARGET_ROOTFS_EXT2_SIZE on the web but finally found the menu where you need to go within make menuconfig : Filesystem image > exact size. The default value was in my case 60M, it seems changing it to 75M will fix the make error.
