aufs-util fails to compile against aufs.h from 5.15.41 branch

[GIJack]

I am using the 5.15.41 branch

I am trying to compile the latest aufs-util from sourceforge:

Hmm, on my test system, $ make CPPFLAGS=-I.../aufs5-linux/usr/include BuildDIRREN=yes BuildFHSM=yes -B all cc -O -Wall -Werror -I.../aufs5-linux/usr/include -D_GNU_SOURCE -I./libau -DAUFHSM_CMD=\"/usr/bin/aufhsm\" -DMOUNT_CMD=\"/bin/mount\" -DUMOUNT_CMD=\"/bin/umount\" -DAUFHSM ver.c -o ver ./ver No error. I'm afraid you've forgot specifying CPPFLAGS after running "make headers_install" under aufs5-linux or aufs5-standalone tree. And if your compiler is musl, then I'd sugest you to specify Glibc=no in your command line. This is not a final solution, since there may exist something to fix in aufs-util. Glibc=no is just a temporary work-around. J. R. Okajima

As a next step to "mission: make headers_install and Glibc=no", I'd like you to try this patch. J. R.

I think I am missing something. What about this build script is wrong:
