Hi Marcus,
Thank you for your reply.
The source files are added to the CMakeLists.text files. But they are not
added by my self, they are added when I use "gr_modtool add -t general
my_block" and "gr_modtool makexml my_block" to make a new block and xml
file.
Only the my_block.h file in include directory contains API
class MY_MODULE_API my_block : virtual public gr::block
{
...
}
Could you please tell me how to check the API property for the block?
Thanks in advance.
Best regards,
Su
