Hello all,
While compiling the linux kernel using ALFS, I got a bunch of errors for
sign-file.c causing the build to fail. Complete 151-kernel build log:
http://paste.ubuntu.com/19860229/ [1] [1] [1]
/usr/lib/gcc/x86_64-pc-linux-gnu/6.1.0/../../../../lib64/libcrypto.a(dso_dlfcn.o):
In function `dlfcn_globallookup':
dso_dlfcn.c:(.text+0x11): undefined reference to `dlopen'
dso_dlfcn.c:(.text+0x24): undefined reference to `dlsym'
dso_dlfcn.c:(.text+0x2f): undefined reference to `dlclose'
Those functions are in /lib/libdl-2.23.so. Do you have that file installed?
It should have been installed as a part of glibc.
Here is the output of a find command executed in chroot:
root:/lib#$ find / -name "libdl*"

/tools/lib/libdl-2.23.so
/usr/lib/libdl.a
/usr/lib/libdl.so
As you can see, its there.
OK, it's there, but it is not being found. I always build the kernel
manually so I'm not sure what jhalfs does for this. Run ldconfig to
ensure the library cache is up to date and try configuring/building the
kernel manually.
So... I tried both suggestions. Did all the command for building the
kernel manually. Didn't work. Ran `ldconfig'. Tried `make' again. Same
errors:
root:/sources/linux-4.6.3#$ ldconfig
root:/sources/linux-4.6.3#$ make

As you can see, I have CALL scripts/checksyscalls.sh but no HOSTCC
scripts/sign-file. I also have a lot of things you don't (unless you
edited the listing for brevity.)
To see what is actually being called, use 'make V=1' If we can see what
is actually being run, perhaps we can run down the problem.
