json-c and jsoncpp are installing same file in same location: /usr/include/json/json.h

json-c installs the following /usr/include/json/json.h

Code:
/*

#endif

#include "bits.h"

#include "arraylist.h"
#include "json_util.h"
#include "json_object.h"
#include "json_tokener.h"

#ifdef __cplusplus

#endif


jsoncpp installs the following /usr/include/json/json.h:

Code:


#ifndef JSON_JSON_H_INCLUDED
# define JSON_JSON_H_INCLUDED

# include "autolink.h"
# include "value.h"
# include "reader.h"
# include "writer.h"
# include "features.h"

#endif // JSON_JSON_H_INCLUDED



Chromium pulls in jsoncpp which leads to file collision:

Code:
* Detected file collision(s):
 *
 *      /usr/include/json/json.h
 *
 * Searching all installed packages for file collisions...
 *

 *      /usr/include/json/json.h
 *
 * Package 'dev-libs/jsoncpp-0.5.0' NOT merged due to file collisions. If
 * necessary, refer to your elog messages for the whole content of the
 * above message.


Of course i want to install the new version of chromium so i delete /usr/include/json/json.h and after that i'm able successfully to install jsoncpp (and chromium respectively).

BUT pusleaudio-3 does ot compile with jsoncpp's /usr/include/json/json.h:

Code:
>>> Source configured.
>>> Compiling source in /var/tmp/portage/media-sound/pulseaudio-3.0/work/pulseaudio-3.0 ...
make -j1
make  all-recursive

/usr/include/stdlib.h: In function ‘atoi’:
/usr/include/stdlib.h:148:6: error: unknown type name ‘__THROW’


/usr/include/json/features.h is also jsoncpp offspring.

So if i want to have pulseaudio-3 successfully built i have to remove jsoncpp and re install json-c, but then chromium complains

Code:
!!! existing preserved libs:
>>> package: dev-libs/jsoncpp-0.5.0
 *  - /usr/lib64/libjsoncpp.so.0.5.0
 *      used by /usr/lib64/chromium-browser/libppGoogleNaClPluginChrome.so (www-client/chromium-26.0.1384.2)


My question is how can i have both jsoncpp and json-c with two different /usr/include/json/json.h files on my system :?

I've got the same problem... I'm currently dealing with it by leaving chromium alone, and installing the google-chrome package instead.

Yes that is also an optional solution, i just hope that someone more knowledgeable than me (liek Paweł Hajdan, Jr. for example) will come up with a proper fix. :wink:

*subscribes*

got the same issue

would be interested on how to solve this, too


edit:

if v8 or chromium brings along its own jsoncpp a use-flag for system-jsoncpp would be at least one option to solve this issue

I already sent a PM to Paweł Hajdan, Jr with link to this thread. No response yet, he is on vacation probably :wink:

I'm thinking of filling a bug report, but i still cant decide against which package should i fill it :?

I had the issue too, so I un-applied the jsoncpp change from chromium 25 to the chromium 26 ebuild files to use the embedded jsoncpp instead of using a system-wide jsoncpp library :

I'm currently posting this using chromium 26 with pulseaudio without jsoncpp so everything is fine again for me :D

Today I updated to dev-libs/json-c-0.10 and now pulsaudio compiles fine but chromium fails with:

Code:
In file included from third_party/libjingle/source/talk/base/json.cc:28:0:
third_party/libjingle/source/talk/base/json.h:35:23: fatal error: json/json.h: No such file or directory
compilation terminated.


With the new version json-c installs it's json.h into /usr/include/json-c/
I.e. the only provider of json.h into /usr/include/json/ is jsoncpp now .
To compile chromium i had to install again jsoncpp, preserved-rebuild did not complain of the missing json.h into /usr/include/json/, but chromium did ;)

And the new www-client/chromium-26.0.1403.0 compiles just fine, all issues are gone... Marking as 'solved' 8)

Please do. If in doubt, just file it, it will be routed to the right people (usually both maintainers). File collision is always a bug, and when filed as bug it will always be fixed faster than when discussed on forums (which is one of the first things I drop when shorter on time).

I just got this conflict on the last couple of versions of chromium. i just masked them rather than bothering with editing the ebuild and stuff like that since it's just going to get overwritten the following week.
