Hi fadden,
my "libmyusecase" is having *.c files and all my header files is with the C
linkage as below.
#ifdef _cplusplus
extern "C" {
#endif /* _cplusplus */
...............................
...............................
#ifdef _cplusplus
}
#endif /* _cplusplus */
And i am trying to call the API's part of these *.c in a package containing
*.cpp files. I get undefined reference error.
But when i make the *.c files of "libmyusecase" to *.cpp and remove the C
linkage in the header files i dont get the undefined reference error.
Thanks and Regards,
Sreedhar
