i have .h and .cpp file:

say_hi.h:

   extern "C" {
      void say_hi();
   }

[download]

say_hi.cpp:

   #include <cstdio>
   #include "say_hi.h"
   void say_hi(){
   printf("hello workd!\n");
   }

[download]

then i compile this with

g++ -I. -fPIC -c *.cpp
g++ -shared *.o -I. -olibsay_hi.so

[download]

then use perl Inline CPP to call it:

>perl -e 'use Inline CPP=>q{  \
 #include "say_hi.h" \
 void test(){return say_hi(); } \
 }, INC=>"-I.",LIBS=>"-lsay_hi"; test()'

[download]

Here I got:

perl: symbol lookup error: /home/xxx/test_so/_Inline/lib/auto/e_8555/e_8555.so: undefined symbol: say_hi

But if I test the .so file with below .cpp file test.cpp:

#include "say_hi.h"
main() {
  say_hi();
}

[download]

Compile it:

g++ -L. -lsay_hi test.cpp -o test

Run the test:

>test
hello workd!

[download]

Is there something wrong with my Perl (v5.8.0), or did I miss anything?

thanks a lot!

In reply to use Inline CPP to call function in so file not working by codesoar
