Hi,

We have a problem when we try to make the exercise.

We have the following message from the terminal we try to compile the cpp files:

lias@lias-desktop:~/orocos-tutorials/orocos-rtt-examples/rtt-exercises/hello-7-deployment$ make g++ -g -o libhello-gnulinux.so Hello.cpp -I`rospack find rtt_2.0)`/install/include -I`rospack find ocl_2.0)`/install/include -DOROCOS_TARGET=gnulinux -fPIC -DOCL_DLL_EXPORT -L`rospack find ocl_2.0)`/install/lib -Wl,-rpath `rospack find ocl_2.0)`/install/lib -L`rospack find rtt_2.0)`/install/lib -Wl,-rpath `rospack find rtt_2.0)`/install/lib -lorocos-taskbrowser-gnulinux -lorocos-rtt-gnulinux -lrt -lpthread /usr/lib/gcc/i486-linux-gnu/4.4.3/../../../../lib/crt1.o: In function `_start': (.text+0x18): undefined reference to `main' collect2: ld returned 1 exit status make: *** [libhello-gnulinux.so] Error 1

On the other hand we have an error when we try to execute the deployer.

deployer-gnulinux: command not found

We have probably missed to add this command.

Thanks

You modified the Makefile wrongly. It lacks the '-shared' flag which was
originally in the LDFLAGS of that file. Probably a copy/paste error ?

Use 'git diff' to see the differences you made.

This one comes from your OCL build and should be created in the ocl/build/bin
directory. So you could try to run:
`rospack find ocl_2.0)`/install/bin/deployer-gnulinux

But it's probably better to create a symlink in one of your bin directories to
that location.

Hello,

We are still trying to complete the exercice 7. However we have some difficulties in using the deployer. We don't succes in connecting ports and to "Autostart" the World component. In order to solve the problem we have tried to update rtt to rtt2.0 beta3 and ocl.

The errors are now :

Both this bug and a crash during 'quit' have been fixed. I've pushed the fixes
to the 2.0 mainlines on github. The exercise is running ok here now.

See Peters email yesterday "[Orocos-users] deployer and
RTT_COMPONENT_PATH in beta3". You have to set your RTT_COMPONENT_PATH
in order to find the toolkits.
something like:

export RTT_COMPONENT_PATH=`rospack find
rtt_2.0`/install/lib/orocos:`rospack find rtt_2.0`/install/lib

Hi,

We have a problem when we try to make the exercise.

We have the following message from the terminal we try to compile the cpp files:

On the other hand we have an error when we try to execute the deployer.

We have probably missed to add this command.
