Hello Gautier,

It seems that the program had some issues recognizing/accessing the path defined by flags, maybe because of permissions (I dont know). Instead I decided to install jsbsim (sudo make install) in the default location used by paparazzi-jsbsim (using --prefix=/usr). paparazzi-jsbsim package was of course removed beforehand. This seems to work well without the need of flags. => Problem solved!

Thank you for your help!

You have installed the jsbsim library in the directory /opt/jsbsim (see prefix option), but you are passing compilation flag to link other /usr/local/lib.

You should try change CFLAGS and LDFLAGS for the correct path.

Hi all,

I would like to do a NPS simulation with JSBSim as FDM. For some reasons, I dont want to use the paparazzi-jsbsim package. I precisely followed the steps 
 cvs -z3 -d:pserver:address@hidden:/cvsroot/jsbsim co -D "23 Feb 2015" -P JSBSim 
 cd JSBSim
 ./configure --enable-libraries --enable-shared --prefix=/opt/jsbsim
 sudo make install

Then I added, the following lines to bixler_lisa_m_2.xml file (I wanted to try that one):
 <makefile location="after">
   nps.CFLAGS += -I/usr/local/include/JSBSim
   nps.LDFLAGS += -L/usr/local/lib

In the Paparazzi Center, I build the target without problem, but when I try to execute, I systematically get the following error:

/home/xavier/paparazzi/var/aircrafts/Bixler/nps/simsitl: error while loading shared libraries: cannot open shared object file: No such file or directory

Could someone help me about it? For people who are not using paparazzi-jsbsim package, how did you make it work exactly? An example of nps simulation configuration without using paparazzi-jsbsim package would be perfect. (makefile in airframe, paths to includes/libs,...)
Thank you!
