make fails on missing json.h ?

[=JeffH]

Hi,

I'd previously been able to cleanly compile and test the CT code
<https://code.google.com/p/certificate-transparency/> (on ubuntu 10.04), like so
(after working thru installing the prerequisites listed in
certificate-transparency/src/README)..

hg pull https://code.google.com/p/certificate-transparency/
hg update

make GTESTDIR=/usr/local/src/google/gtest-1.6.0

However, when i circled back around to this yesterday, and re-did the above
sequence (a fair number of updated modules were sucked down), I noted that we
now need to install some new dependencies: curlpp, JSON-C (i.e., make failed,
I re-read the README and noted the new dependencies noted in items 5a & 5b,
fetched them, built 'em)

So the only issues I noted were that the install of json-c apparently didn't
copy json_object_iterator.h to /usr/local/include/json

Once I fixed that, CT completed building. running test didn't work straight
away, on my system I had to ensure I'd done this..

setenv LD_LIBRARY_PATH /usr/local/lib

..and then the make tests ran and everything passed (I haven't this time yet
played with the end-to-end server-client tests), but I haven't tried
client/upload_server_cert.sh, or installed the python modules pyasn1 and
pyasn1-modules. It appears I need to find and install "easy_install" ?

thanks,

=JeffH

I guess that's a problem that needs to be reported to json-c?

I'll update the README to note this might be needed. Thanks.

On my dev platform (FreeBSD) easy_install comes with Python, it seems.
But I guess that's not universally install. I believe the package is
helpfully called ez_install, not easy_install! You don't have to
install them this way, your platform may have a package for them, or
you can presumably do it from source.

It's setuptools on Linux, in fact:

https://pypi.python.org/pypi/setuptools

You can use whatever package manager for Python, I've just found easy_install really convenient.
