Hi Marc,

I've fixed the configure script so that it should now correctly detect the libJSONcpp headers both on Debian and Redhat (and hopefully all other systems).

Could you test the attached patch (it's also in the master branch) and see if it works for you? It should apply to the 5.1 branch too.

Best, Jaap

I am running Fedora 24.

I am trying to install DOMjudge 5.1.2 to start preparing for the next regional contest. When I try to run "configure", it gives an error after checking for jsoncpp/json/json.h. This is because it does not exist. json/json.h does exist.

When I look at the jsoncpp-devel package, it does not have any files that are in a directory named jsoncpp. The documentation states that json/json.h should be used.

Indeed, under Debian the file is at jsoncpp/json/json.h, and this is what the debian documentation says:

• Originally, Jsoncpp library installs headers at prefix/include/json. However, it conflicts with libjson C library. Thus, libjsoncpp package will use /usr/include/jsoncpp as root header directory.

So we should change the configure script to handle both cases properly. I'll have a look at this, but it would require proper testing that json/json.h is indeed the jsoncpp library and a simple program using it can be compiled.

I will skip the submit client for now, and we may decide not to use it at all (we have not used it in the past). However, it would be nice to get it to work. I do not have a Debian system handy to see if the include files are different there.

Does anyone have suggestions for a resolution to this problem?

Besides the above, a quick workaround should be to edit configure.ac and submit/submit.cc and change jsoncpp/json/json.h into json/json.h. Then you need to run ./bootstrap to regenerate configure from configure.ac and then when configuring and installing the system, the submit client should work.
