Errors when attempting a conversion

[dhammerindy]

Please forgive my formatting of this message if it is incorrect. This is my first post here. I've attempted to install php-to-c-extension as outlined in the instructions but something hasn't gone right. When I attempt a conversion I get this...

$ php php-to-c-extension/build_extensions.php Dummy.php
Installing zephir...
You need to run this command from the toplevel of the working tree.
sh: autogen.sh: No such file or directory
./install-json: line 5: ./configure: No such file or directory
make: *** No targets specified and no makefile found. Stop.
Parser statistics: 127 terminals, 99 nonterminals, 458 rules
945 states, 0 parser table entries, 0 conflicts
parser.c:9:25: error: json-c/json.h: No such file or directory
In file included from parser.c:14:

After this comes a long list of entries that look like this:

parser.c:8898: error: âsyntax_errorâ undeclared (first use in this function)
parser.c:8911: error: âxx_parser_statusâ has no member named âscanner_stateâ
parser.c:8917: error: âxx_parser_statusâ has no member named âscanner_stateâ
parser.c:8918: error: âxx_parser_statusâ has no member named âscanner_stateâ

What am I missing here? This is being run on a test OS. I am running CentOS 6.8 which is a VPS powered by VirtualBox. Should I try running this on a different OS? Was there simply an issue with my install where something not listed in the 4 steps didn't get included? My install method for Composer used the Global method.

Any help you can provide would be greatly appreciated. I am really eager to see your application at work.

Solution to the first bit is to clone into json-c

git clone https://github.com/json-c/json-c.git

But then you end up with other issues which I'm still looking at!
