./data directory needed during startup

Hello all,

I tried to build the latest commit from launchpad in António Lima's
development branch. However I have problems executing the resulting
referencer binary.

So what I did is

fetch the sources from launchpad 
bzr branch lp:~referencer-devs/referencer/amrlima_gio_port

configure, build and install them
cd amrlima_gio_port/
./devconfigure
make
make install

the build works fine. when I try to run referencer this only works when
in the working directory a folder "data" exists. Otherwise I get

$ bin/referencer
int main(int, char**):
	setting pythonPath
to :/home/dominik/apps/lib/python:./plugins:/home/dominik/.referencer/plugins:/home/dominik/devel/referencer/amrlima_gio_port/dist/lib/referencer:
terminate called after throwing an instance of 'Gio::Error'
Aborted

if I do
mkdir data
bin/referencer

I see the same behaviour, however if you use ./src/referencer it works
for me

Does installing as non-devconfigure work?
./configure
make
make install

You are right it works with ./src/referencer but only When I execute it
from the root directory of the branch! If I do 

cd src
./referencer 

it fails with the same error again. I guess your case works only since
a data directory and the needed files exist in the root directory.
Since the files already exist there also subsequent startups work as
expected.

Re: ./data directory needed during startup

I think the main problem is in the Utility::findDataFile function. I
could fix the problem with

=== modified file 'src/Utility.C'
--- old/src/Utility.C	2011-03-24 16:55:22 +0000
+++ new/src/Utility.C	2011-08-15 15:39:32 +0000
 <at>  <at>  -213,9 +213,7  <at>  <at> 
 		localfile = filename;
 	} else {
 		localfile = Glib::build_filename (
-			Glib::get_current_dir (), "data");
-		localfile = Glib::build_filename (
-			localfile, filename);
+		    DATADIR, filename);
 	}

 	Glib::RefPtr<Gio::File> uri =

I am however not sure if this is what the findDataFile function is
intended for. I also attached the patch file. Please have a look!

kind regards

Dominik

Hi Dominik,

I'll look at you patch in the next days and commit to my gio_port
branch. I hope I'll be able to work on referencer in the next month.
Been really busy :( .

Thank you for reporting and fixing this!

António Lima

Hi,

This is fixed in my branch http://bazaar.launchpad.net/~referencer-devs/referencer/amrlima_gio_port/revision/876

The problem was introduced by a change due to the gio port. Thanks Dominik for reporting!

Regards,
António Lima

Does installing as non-devconfigure work? ./configure make make install
fails for me too if executed outside the build directory where the data folder is located! somehow the current directory is important when referencer is started! kind regards dominik
