compiling the tutorial

[DiBeck]

Hello again,

I hope I am annoying you not to much, with all the questions. I tried to run one of the tutorial skips by using

make tutorial_sim_iterated

the first error I received was that he could not include "../sim_main.h". Therefore I changed the hello_world_sim_iterated.cpp line 2

#include <sim_main.h>

and include the following paths into ~/.profile

export PATH="/usr/local/include/sim:$PATH"
export PATH="/usr/local/libc:$PATH"
export PATH="/usr/local/lib/libsim:$PATH"

Now I run into the following:

Undefined symbols for architecture x86_64:
  "toExprString(char const*)", referenced from:
      bool Sim::get<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, char [6]>(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> >&, char const (&) [6], SimSignal const&) in ccBhzTjU.o
  "Endl(SimIO&)", referenced from:
      SimControl<Kernel>::simulate(int, char**) in ccBhzTjU.o
  "ExprParser::parse_file(char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> >&)", referenced from:
      SimControl<Kernel>::simulate(int, char**) in ccBhzTjU.o

..... two more pages of complains

     std::basic_string<char, std::char_traits<char>, std::allocator<char> > ExprToValueErrorDescription<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >(ExpressionPtr const&) in ccBhzTjU.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
make: *** [tutorial_sim_iterated] Error 1

Do you know what I am doing wrong? If i remember right, that this is also the problem when i am running the te_causality_master from olavolav. Did i forget to add some paths?

Bye the way the ./test inputworks like a charm

Thanks again for all your help.

Hi,
Ask as much as you want, it's the only way to fix these isssues!
I see where the issue is, the OBJBASE variable is undefined. Lines 103 and 104 from the Makefile should read:

tutorial_sim_iterated: $(OBJS) tutorial/hello_world_sim_iterated.cpp
$(CC) $(CFLAGS) tutorial/hello_world_sim_iterated.cpp $(OBJS) -o tutorial_sim_iterated $(LDFLAGS)

And the include from tutorial/hello_world_sim_iterated.cpp should read: #include "../include/sim_main.h"

BUT, since you have installed simkernel as a library, you have another option, you can keep your include as #include <sim_main.h> and instead change lines 103 and 104 of the Makefile to:

tutorial_sim_iterated: $(OBJS) tutorial/hello_world_sim_iterated.cpp
$(CC) $(CFLAGS) tutorial/hello_world_sim_iterated.cpp $(OBJS) -o tutorial_sim_iterated $(LDFLAGS) -lsim

After that you should be able to run the tutorial with ./tutorial_sim_iterated tutorial/control.txt

If you have issues with te-causality please open an issue there. I might also be able to help with that.

Perfect! that solved the problem.
