Good afternoon, I am following the instructions provided here to install ROOTANA (and MIDAS, more in general). When I try to make I get the following error

libMidasInterface/TMidasOnline.cxx: In member function ‘bool TMidasOnline::sleep(int)’: libMidasInterface/TMidasOnline.cxx:194:3: error: ‘ss_suspend_set_dispatch_ipc’ was not declared in this scope
ss_suspend_set_dispatch_ipc(NULL);
^~~~~~~~~~~~~~~~~~~~~~~~~~~
libMidasInterface/TMidasOnline.cxx:194:3: note: suggested alternative: ‘ss_suspend_set_rpc_thread’
ss_suspend_set_dispatch_ipc(NULL);
^~~~~~~~~~~~~~~~~~~~~~~~~~~
ss_suspend_set_rpc_thread
Makefile:339: recipe for target 'obj/TMidasOnline.o' failed make: *** [obj/TMidasOnline.o] Error 1

And the compilation stops. Is this a known issue?
My system is Ubuntu 18 and I am running ROOT 6.18.00

Hi,

Thank you, commenting out the line worked and we can now compile the code. However, when we try to run ana.exe or anaDisplay.exe, we get the following errors:

Error in <TCling::RegisterModule>: cannot find dictionary module TMainDisplayWindowDict_rdict.pcm
Error in <TCling::RegisterModule>: cannot find dictionary module TRootanaDisplayDict_rdict.pcm
Error in <TCling::RegisterModule>: cannot find dictionary module TFancyHistogramCanvasDict_rdict.pcm
 

We see that the files are in /rootana/obj but we cannot find a way to point the compiler to them.

Could you please advise how to proceed,

Many thanks

Hi Lauren,

Do you see an actual problem that results from those error messages?  As I mentioned before [1] I get that error message, but it doesn't seem to actually cause a problem.

this problem is not unique to ROOTANA and ROODY, take a search for this problem (and solutions) on the ROOT forum...

K.O.

(please send elog messages in "plain text" mode, otherwise I cannot quote your text)

The problem with missing ss_suspend_set_dispatch_ipc() is now fixed, rootana commit 
https://bitbucket.org/tmidas/rootana/commits/52fdedb5745fa9b6739a16a6faab8b9d40108045

If you run rootana online in graphical mode (or call TMidasOnline::sleep() yourself), you may re-encounter
the problem of recursive calls to the event handler, depending on which version of MIDAS you use. The
probability of this problem happening is probably reduced to zero in all 2019 MIDAS releases and it is
definitely fixed in the most recent commits to MIDAS (this will be the midas-2019-09 release, most likely).

Hello,

We've been attempting to make and run the executables in the

It is a problem inside ROOT. The pcm files replaced the dict.h files during the switch from CINT in 
ROOTv5 to LLVM in ROOTv6. But they have a mistake and use the wrong path for finding these files. 
I.e. search for "cannot find dictionary module" on the ROOT forum https://root-forum.cern.ch

K.O.

Hi,

I just wanted to be certain about how serious this problem is.  These error message always happens for me when I 
run on macos machine as well.  But the errors don't seem to have any real effect; my programs still run fine.

Is that the case for you too?  You get the error messages, but everything still works?

If so, then I agree that it would be nice to fix, but it is less critical; I will try to get to it.

Cheers,
Thomas

Hi,
We are getting these warning of dictionary modules missing and nothing happens. I would have expected some graphical
interface to load up. I have tried copying these .pcm files from the packages/rootana/obj folder to
packages/rootana/examples, now the missing dictionary module complaint goes away but no graphical interface loads up.
Could you please assist with this?

Kind regards,
Hassan

ROOT v6 has been around for a while now, finally got around to test it with ROOTANA.

a) using root-v6-06-08
b) everything compiles and links
c) the example applications - i.e. display_example.exe - seem to run correctly
d) user applications linked against librootana.a show a problem loading the ROOTANA rdict.pcm files.

Failure to load the rdict.pcm files seems to prevent some functions, at least in the GUIs.

I do not fully understand how ROOT is supposed to find these files and I am asking for help on the ROOT forum.

In the mean time, there is a work around:
- symlink all rdict.pcm files into same place as the executable: ln -sv $ROOTANASYS/*/*.pcm .
- symlink all (many) .h files into the same place (this is a bit extreme): ln -sv $ROOTANASYS/include/* .

K.O.

> ROOT v6 has been around for a while now, finally got around to test it with ROOTANA.

The problems with loading rdict.pcm files and c++ .h header files is resolved, ROOTANA should be fully usable with ROOTv6:

Put this in your login file:

export ROOTANASYS=$HOME/packages/rootana
export ROOT_INCLUDE_PATH=$ROOTANASYS/include
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTANASYS/obj

Explanation:
- LD_LIBRARY_PATH is used to search for rdict.pcm files.
- ROOT_INCLUDE_PATH is used to find the c++ .h header files.

K.O.

This is a new forum for discussing the rootana MIDAS analyzer.
