Sorry for being so vague. I was more curious about the need for the static. I am trying to run the pow() example from the Stu book. Originally I typed it off and added my own test bench. That crashed right away with a segmentation fault. Next I took the example from the accompanied CD. I modified the vpi_user.c to not needing the other application that comes along with that chapter 2 example and compiled it with: iverilog-vpi pow_vpi.c vpi_user.c iverilog -opow_test.vvp pow_test.v vvp -M. mpow_vpi pow_test.vvp The output I am getting is: $pow PLI application is being used. Segmentation fault What is odd, even after changing the definition and the implementation of the calltf, sizetf, compiletf functions I am getting warnings about incompatible pointer types. For example the calltf function I changed from: PLI_INT32 PLIbook_PowCalltf(PLI_BYTE8 *user_data); to: static int PLIbook_PowCalltf(PLI_BYTE8 *user_data); When compiling I am still getting: > iverilog-vpi pow_vpi.c vpi_user.c Compiling pow_vpi.c... pow_vpi.c: In function ‘PLIbook_pow_register’: pow_vpi.c:46: warning: assignment from incompatible pointer type pow_vpi.c:47: warning: assignment from incompatible pointer type pow_vpi.c:48: warning: assignment from incompatible pointer type Compiling vpi_user.c... Making pow_vpi.vpi from pow_vpi.o vpi_user.o... Line 46, 47, and 48 are: tf_data.calltf = PLIbook_PowCalltf; tf_data.compiletf = PLIbook_PowCompiletf; tf_data.sizetf = PLIbook_PowSizetf; I even removed the .o and the .vpi file to make sure it compiles again, but still get the warning. The example can be downloaded from this page: http://sutherland-hdl.com/pli_book_files/pli_handbook_examples_unix.tar.gz Any idea what I am doing wrong? Thanks for the help.
