Hi,
At the ROOT prompt, I try to pass a string into an object. This
works in my KCC compiled root on my linux PC, but does not work on my
gcc 3.3 compiled root on my Mac. I went through a bunch of emails
with similar questions on roottalk, but I didn't get anywhere. I
believe this feature must be at the CINT level, since the classes do
compile okay.
Here is the successful running on the kcc compiled root system:
root [0] .L test.cc++
Info in <TUnixSystem::ACLiC>: creating shared library
/home/bjk/test2/./test_cc.so
root [1] test T
root [2] T.set("value")
offset is value
Here is what happens on the macosx version :
root [0] .L test.cc++
Info in <TUnixSystem::ACLiC>: creating shared library
/Users/bjk/releases/4.11.1ana/test2/./test_cc.so
ld: warning -prebind has no effect with -bundle
root [1] test T
root [2] T.set("value")
Error: Can't call test::set("value") in current scope FILE:(tmpfile)
LINE:1
Possible candidates are...
filename line:size busy function type and name (in test)
(compiled) 0:0 0 public: void set(string value);
Error: Symbol T is not defined in current scope FILE:(tmpfile) LINE:1
Error: Failed to evaluate T.set("value")Possible candidates are...
filename line:size busy function type and name
*** Interpreter error recovered ***
From the threads on roottalk I have seen, I have tried a range of
things to get this to work, such as :
root [0] #include <string>
root [1] using namespace std
root [2] string val = "value"
root [3] .L test.cc++
Info in <TUnixSystem::ACLiC>: creating shared library
/Users/bjk/releases/4.11.1ana/test2/./test_cc.so
ld: warning -prebind has no effect with -bundle
root [4] test T
root [5] T.set(val)
Error: Can't call test::set(val) in current scope FILE:(tmpfile) LINE:1
Possible candidates are...
filename line:size busy function type and name (in test)
(compiled) 0:0 0 public: void set(string value);
Error: Symbol T is not defined in current scope FILE:(tmpfile) LINE:1
Error: Failed to evaluate T.set(val)Possible candidates are...
filename line:size busy function type and name
*** Interpreter error recovered ***

The code I am trying to execute is :
test.cc :
#include <iostream>
#include "test.hh"
using namespace std;
test::~test() {
}
test::test(){
}
test.hh :
#include <iostream.h>
class test {
public:
std::string Offset;
test();
~test();
inline void set(std::string value)
{Offset = value;
std::cout << "offset is " << value << std::endl; }
};
What am I doing wrong here ?
Thanks !
Ben
p.s. I am using root 3.10.1 compiled on my Mac osx 10.3 with gcc 3.3.
