Dear experts,
I am relatively new to Fluka and I am trying to follow the guidelines
given in
http://www.fluka.org/fluka.php?id=examples&sub=example3&node=4
in order to use a C function, containing ROOT classes, that I then call
inside my source.f . I am working on a Linux machine (Ubuntu 16.04).
With minimal adaptations of the makefile that can be found there (
http://www.fluka.org/content/examples/Makefile ) I can compile both the
fortran routines and the C code. However when the makefile invokes
lfluka I am getting an error.
More in detail, the error message is
/usr/bin/ld: FluLib.o: undefined reference to symbol '_ZN7TObjectdlEPv'
/home/scompar/alice/sw/ubuntu1604_x86-64/ROOT/v5-34-30-alice9-1/lib/libCore.so.5:
error adding symbols: DSO missing from command line
which seems related to ROOT. Indeed if I take the link command as
created by lfluka
gfortran -msse2 -mfpmath=sse -fPIC -O3 -g -mtune=generic
-fexpensive-optimizations -funroll-loops -fstrength-reduce -Wall
-Wuninitialized -Wno-tabs -Wline-truncation -Wno-unused-function
-Wno-unused-parameter -Wno-unused-dummy-argument -Wno-unused-variable
-Wno-conversion -Wunused-label -Waggregate-return -Wcast-align
-Wsystem-headers -ftrapping-math -frange-check -fbackslash -fdump-core
-fbacktrace -ffpe-trap=invalid,zero,overflow -finit-local-zero
-ffixed-form -frecord-marker=4 -funderscoring -fno-automatic
-fd-lines-as-comments -fbounds-check
-I/home/scompar/cernbox/Documents/Fluka/flukapro -v -o rootfluka
-Xlinker -Map -Xlinker rootfluka.map fluka.o dlornbck.o
source_interface.o stuprf.o magfld.o mgdraw.o FluLib.o libResults.so
-L/home/scompar/cernbox/Documents/Fluka -lflukahp -l gfortran -l m
-shared-libgcc
I append by hand at the end `root-config --glibs` -lstdc++ , and I
execute it as such, then everything works [1]. However I find no simple
way to have these two further instructions to be "generated" by the
lfluka command.
Is there a way to add qualifiers to lfluka in such a way that the link
command contains this further information ? Of course any other
alternative solution would be also welcome!
Thanks and best regards
Enrico
[1] In order for the link command to work I also have to run,
immediately before, the line 'ar x
/home/scompar/cernbox/Documents/Fluka/libflukahp.a fluka.o' , to extract
fluka.o
