autoreconf fails on macOS Sierra

[gh0st42]

Just tried to build serval-dna on a macOS Sierra machine.

$ autoreconf -f -i
src/libsodium/Makefile.am:1: error: Libtool library used but 'LIBTOOL' is undefined
src/libsodium/Makefile.am:1:   The usual way to define 'LIBTOOL' is to add 'LT_INIT'
src/libsodium/Makefile.am:1:   to 'configure.ac' and run 'aclocal' and 'autoconf' again.
src/libsodium/Makefile.am:1:   If 'LT_INIT' is in 'configure.ac', make sure
src/libsodium/Makefile.am:1:   its definition is in aclocal's search path.
autoreconf: automake failed with exit status: 1

libsodium is already installed using brew but this should not make a difference at this stage since I don't even get to the "configure" step. Prior to autobuilding libsodium this was not a problem on macOS.

You might need to install libtool?

What version of autotools? Which commit of serval-dna? Please read INSTALL.md, it clearly says:

autoreconf -f -i -I m4

[gh0st42]

libtool is installed:

$ which libtool
/usr/bin/libtool
$ libtool
error: /Library/Developer/CommandLineTools/usr/bin/libtool: no output file specified (specify with -o output)
Usage: /Library/Developer/CommandLineTools/usr/bin/libtool -static [-] file [...] [-filelist listfile[,dirname]] [-arch_only arch] [-sacLT] [-no_warning_for_no_symbols]
Usage: /Library/Developer/CommandLineTools/usr/bin/libtool -dynamic [-] file [...] [-filelist listfile[,dirname]] [-arch_only arch] [-o output] [-install_name name] [-compatibility_version #] [-current_version #] [-seg1addr 0x#] [-segs_read_only_addr 0x#] [-segs_read_write_addr 0x#] [-seg_addr_table <filename>] [-seg_addr_table_filename <file_system_path>] [-all_load] [-noall_load]

And regarding -I m4 it is optional, adding it also does not help with this problem.

This is the most recent commit in master branch.

If i revert back to a commit prior to the required libsodium subtree it all builds fine on the machine. git checkout 0382e7990e4704991de767057b11c4f11c7b2ba8

The current version interestingly enough builds just fine on a real old mac with El Capitan installed.

I don't have a Mac with Sierra handy to perform more testing.

The clue is in the error message. The libsodium Makefile.am definitely contains an LT_INIT line, so it must be that LT_INIT is not in aclocal's search path. A missing brew package, perhaps? In Debian, the M4 autoconf macros come in their own package called autoconf-archive.

If you install the libtool version from brew it works, apple command line developer tools version alone doesn't seem to work.

Could you please post the output of libtool -V? Also, which version of Xcode you have installed? Those pieces of information would help me improve the configure scripts to detect problems like this and at least issue helpful error messages. I might have to create an autogen.sh script.
