Debugging a c function in a R package

Question

I want to debug the c function of an R package using R -d gdb , but I get the following after setting breakpoint at c function C_MIM() , I got the following information and also "cannot find bound of the current function" so I could not print out any variable value in this case. Is there something I am doing wrong? Or for some R package, it is not possible to debug?

Breakpoint 1, 0x00007fffdee0035f in C_MIM ()
   from /home/sunxd/R/x86_64-pc-linux-gnu-library/3.4/praznik/libs/praznik.so
(gdb) list
76      in ../sysdeps/unix/syscall-template.S
(gdb) n
Single stepping until exit from function C_MIM,
which has no line number information.

事实证明，必须拥有源代码并使用特定的gcc / cc选项编译R包。
