FYI

Here is a service startup script for Conquest running on Fedora 16 which uses systemctl (systemd) as its service manager.

[Unit]
Description=Control Conquest PACS server
After=postgresql.service syslog.target network.target network.service


[Service]
Type=simple
WorkingDirectory=/home/conquest/Conquest
ExecStart=/home/conquest/Conquest/dgate 
ExecStop=-/home/conquest/Conquest/dgate --safequit:
ExecReload=/home/conquest/Conquest/dgate --safequit: ; sleep 5 ; -/home/conquest/Conquest/dgate


[Install]
WantedBy=multi-user.target

copy and paste this into the file conquest-pacs.service changing the directory paths to where your dgate executable is.

copy the file into /lib/systemd/system

execute
$ systemctl daemon-reload
$ systemctl enable conquest-pacs.service

to start dgate execute
$ systemctl start conquest-pacs.service

to stop
$ systemctl stop conquest-pacs.service

to restart
$systemctl restart conquest-pacs.service

to check status
$ systemctl status conquest-pacs.service

Hi

I have a similar problem. I am trying to start dgate from a script using:

# /conquestdir/dgate -v -w/conquestdir &

dgate seems to fail to load dicom.ini. The strange thing is it definitely finds the directory. If I mistype it it reports it as not existing. Starting dgate in its home directory works fine. Could this be the old forward/backslash issue between windows and linux?

I am trying to set up a systemctl script to start dgate as a service on Fedora 16.

Ok, as predicted the web interface failed to run.

Soved by copying contents of /usr/lib/cgi-bin/ to /var/www/cgi-bin/

and /var/www/conquest.jpg to /var/www/html/

alternatively
change maklinux_postgres from

sudo cp dgate /usr/lib/cgi-bin
sudo cp dicom.sql /usr/lib/cgi-bin
sudo cp dicom.ini.www /usr/lib/cgi-bin/dicom.ini
sudo cp sample.cq /usr/lib/cgi-bin

sudo cp ActiveFormProj1.ocx /var/www
sudo cp conquest.jpg /var/www

to

sudo cp dgate /var/www/cgi-bin
sudo cp dicom.sql /var/www/cgi-bin
sudo cp dicom.ini.www /var/www/cgi-bin/dicom.ini
sudo cp sample.cq /var/www/cgi-bin

sudo cp ActiveFormProj1.ocx /var/www
sudo cp conquest.jpg /var/www

Now I can see the web interface. However the interface is not communicating with the server and SE linux is having a fit.

[Solution]
SE Linux is blocking httpd access to the network or alternatively port 5678.
From root execute:
setsebool -P httpd_can_network_connect 1

Warning this has the potential to allow unfriendly code to execute scripts!

Great, now I can see patients and view images. However, I can't access the server from other computers on the network.

[Description] The firewall is blocking access to the script from outside the host.
[Solution]
On your host run the firewall configuration with root privileges. Under "Other Ports" add port 5678 with protocol tcp. Under trusted services make sure Service WWW (HTTP) port 80/tcp is enabled. See warning above.

Also change all occurrences of 127.0.0.1 to ip address of host in /var/www/cgi-bin/dicom.ini

At last, I can view the sample patients and images across the network.

Many thanks Marcel for an impressive piece of software and thanks to Mark Pearson for the startup scripts.

Here are some pointers on setting up and checking the database using Postgresql for people like me who aren't familiar with Postgres

To create the database:
$ createdb -Upostgres conquest

If you get error "Ident not authenticated" edit the pg_hba.conf file in
/var/lib/pgsql/data
and replace all instances of "indent" with "trust"
Warning: this will open up your databases completely. Once everything is working you can experiment with more restrictive settings.

Postgresql stores the database in /var/lib/pgsql/data/base

To verify that the database was created enter:
$ psql -Upostgres conquest

You should get a new prompt:
conquest=#

Enter \l at the prompt for a list of databases on your system. You should get:

List of databases
Name | Owner | Encoding | Collation | Ctype | Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
conquest | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres
: postgres=CTc/postgres
template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres
: postgres=CTc/postgres
(4 rows)

Exit from Postgres by typing \q

Now regenerate the database by entering:
$./dgate -v-r

There appear to be a number of error messages if this is the first time the database is generated.If the images were added successfully you will get some success messages. You can verify that the database structure was created by starting psql again and entering at the prompt:

conquest=# \d

You should get:

List of relations
Schema | Name | Type | Owner
--------+---------------+-------+----------
public | dicomimages | table | postgres
public | dicompatients | table | postgres
public | dicomseries | table | postgres
public | dicomstudies | table | postgres
public | dicomworklist | table | postgres
public | uidmods | table | postgres
(6 rows)

Hope this helps

Here is my maklinux_postgres file

export LD_LIBRARY_PATH="/usr/lib/pgsql/"
gcc -o lua.o -c lua_5.1.4/all.c -Ilua_5.1.4
g++ -I/usr/include/pgsql -DUNIX -DNATIVE_ENDIAN=1 -DHAVE_LIBJASPER -DHAVE_LIBJPEG -DPOSTGRES -Wno-write-strings total.cpp lua.o -o dgate -lpthread -L/usr/lib/pgsql/ -lpq -Ijasper-1.900.1-6ct/src/libjasper/include -Ljasper-1.900.1-6ct/src/libjasper/ -ljasper -ljpeg -Ijpeg-6c -Ljpeg-6c -Ilua_5.1.4 -Wno-multichar
rm lua.o
pkill -9 dgate
sleep 0.2s


cp dicom.ini.postgres dicom.ini
cp dicom.sql.postgres dicom.sql


sudo cp dgate /usr/lib/cgi-bin
sudo cp dicom.sql /usr/lib/cgi-bin
sudo cp dicom.ini.www /usr/lib/cgi-bin/dicom.ini
sudo cp sample.cq /usr/lib/cgi-bin


sudo cp ActiveFormProj1.ocx /var/www
sudo cp conquest.jpg /var/www

I have not yet tested the web server interface. I am fairly sure it is not going to work as Apache on Fedora uses the directory /var/www/cgi-bin. Also the use of the /usr/local directory on Fedora is deprecated.

A simpler option for distribution might be to create a Fedora RPM although this tends to be quite specific.

Ok I now have an executable. This is what I did in addition to the above:

[Title] error: 'JSAMPLE16' undeclared

[Solution]
See http://forum.image-systems.biz/viewtopic.php?f=33&t=2494

After doing in jpeg-6c: (see linuxmanual.pdf in Conquest dir)
sudo make install
Add
sudo make install-lib

[Title] PostGresql directories

[Solution]
Change maklinux_postgres, line 1 from
export LD_LIBRARY_PATH="/usr/local/pgsql/lib/"
to
export LD_LIBRARY_PATH="/usr/lib/pgsql/"
and line 3 from
g++ -I/usr/local/pgsql/include -DUNIX -DNATIVE_ENDIAN=1 -DHAVE_LIBJASPER -DHAVE_LIBJPEG -DPOSTGRES -Wno-write-strings total.cpp lua.o -o dgate -lpthread -L/usr/local/pgsql/lib -lpq -ljasper -ljpeg -Ijpeg-6c -Ljpeg-6c -Ilua_5.1.4 -Wno-multichar

[Description]
odbci.cpp: In member function ‘virtual BOOL Database::Open(const char*, const char*, const char*, const char*)’:

[Solution]
See http://forum.image-systems.biz/viewtopic.php?f=33&t=3216 post 3 and 4
replace Sleep(555) by delay(555)

[Description]
/usr/bin/ld: cannot find -ljasper

[Solution]
Copy libjasper.a from
conquestlinux1416/jasper-1.900.1-6ct/src/libjasper/.libs
to
/usr/local/lib

Ok we now have an executable. If there is a more elegant way of doing the above please let me know.

Thanks, the above fix worked on Fedora 14.

I am currently trying to install Conquest on Fedora 14. Having read this thread http://forum.image-systems.biz/viewtopic.php?f=33&t=3216 by Azhar I thought I would post my experiences as he seems to have got a bit further than I have. I am running Fedora 14 with KDE 4.6 and Postgresql 8.4.8-1

First problem:
While making the IJG library
/usr/bin/install -c -m 644 ./cjpeg.1 /usr/local/man/man1/cjpeg.1
/usr/bin/install: cannot create regular file `/usr/local/man/man1/cjpeg.1': No such file or directory
make: *** [install] Error 1

Changed:
configure, line 55 from mandir='${prefix}//man' to mandir='${prefix}/share/man'
makefile.cfg, line 20 from mandir = $(prefix)/man/man$(manext) to mandir = $(prefix)/share/man/man$(manext)

I will post other problems and (hopefully) solutions as I encounter them

Cheers
