[linux-lvm] configure fail with option --enable-notivy-dbus

[Oliver Rath]

Hi list,

configuring lvm2 failed with --enable-notify-dbus option, but
unfortunatly without no konkrete error-message:

$ ./configure --enable-lvmetad --enable-lvmpolld --enable-udev_sync
--enable-udev_rules --enable-applib --enable-cmdlib
--enable-dbus-service --enable-dmfilemapd --enable-python3_bindings
--enable-notify-dbus

[..]
checking whether to install fsadm... yes
checking whether to install blkdeactivate... yes
checking whether to use dmeventd...
checking for getline in -lc... no
checking for canonicalize_file_name in -lc... no
checking for dlopen in -ldl... no
checking for log10 in -lm... no
configure: error: bailing out


Without the last option, configure runs fine. The git-codebase is from
today, all neede libs shoud be installed, the System is Ubuntu-16.04.

What must I do?

Tfh!
Oliver

This is because of missing log10 function from m library (wherever that
comes from) and has nothing to do with dbus. So enabling or disabling it
should have absolutely no effect.

Were you configuring lvm2 on the same machine using the same environment?

Similarly canonicalize_file_name, dlopen, and getline - the first is a
GNUism, and we really should have a fallback if it is not found (there
is a usable gnulib version), but dlopen and getline?

Those are both standard calls now - dlopen is part of POSIX.1-2001 and
getline was added in POSIX.1-2008.

Are you compiling with an old or non-GNU libc?

My used glibc is:

Ok, that helps. I figured out, that libm is part of libc6, libc6-dev is
installed and has a include file called tgmath.h

$ grep -iR "define log10" /usr/include/
/usr/include/tgmath.h:# define log10(Val) __TGMATH_UNARY_REAL_IMAG (Val,
log10, __clog10)
/usr/include/tgmath.h:# define log10(Val) __TGMATH_UNARY_REAL_ONLY (Val,
log10)
[..]

So it seems all needed files are installed. But the message still remains.

Yes. At the moment. If you neede further information, just let me know!

That's a macro for complex log operations. You want the floating point
version from bits/math-finite.h (included by math.h).

Try compiling the log10 test autoconf uses yourself. It should be something
simple like:

char log10();

int main(int argc, char **argv)
{
return log10();
}

Then compile it with -lm and note any errors (you may get a warning about
redefining a built-in but this is just to test that the symbol can be
found).

Bryn.
