c - Gdb repeated "no symbol table is loaded" -


OK, I can not use gdb to try despite a lot of solutions.

My makefile cc -g _________ and myfilesys 

  & gt; gdb breaks myfilesys (gdb) my_linked_list.c: 90A symbol table is not loaded, read the symbol from the "file" command ... (gdb) file myfilesys / home / jsexton / work / cs492 / hw3 / myfilesys ... Use (No debugging symbols found) ... done. (GDB) break my_linked_list.c: 90 A symbolic table is full, use the "file" command ...   
 Can anyone see a problem? My program is 30C C is broken into files, so I really need to use the file: [line number] thing.   
 
 
 Although you have  myfilesys  on your executable  cc -g < If you claim to be compiled with / code>, then there is no proof in your attempt to use GDB, code> file  command:  
 
  (gdb ) File myfilesys  
  /.../ Reading symbols from myfilesys ... (no debugging signal found) ... done.    
 You have to take on your word that you have actually used  cc -g  to compile the code myfilesys  It means that you have either stripped the symbols from your binary (I am not likely, but I mention the possibility), or none of your object files is debug. Belonging to the latter, you have to implement the  cc -g -c  compilation in each individual source file. Then, each of the resulting object files will have debugging signals, and consequently the executable will also have debugging signals (unless you remove them in the bar after linking).  
 Standard makefiles such as  GMK , it can usually be accomplished with the  -g  by increasing the  CFLAG  variable. Below is a complete Mesophile that shows it with three source files:  
  cflag = - g myfiles: come b $ $ (cc) $ ^ -o $ @   
 GCC already has the rules inherent, which can make the  .o  file related to the  .c  file. However, you can change the  CFLAGS  variable to change the command line argument passed to the compiler. The directory is pre-processing and usually teaches  CPPFALAGS  variables (C + + specific flag with  CXXFLAGS , but  CPPFALGS  option C and C + + Compiler got to both of them).  
 We need to define a clear rule to make the executable  myfilesys  ( $ (CC)  rule a tab character, a makefile requirement Is indented with) After typing  create , there will be symbols in the executable, and GDB will not report missing symbols in your executable (it can report missing symbols from any library you use ):  
 
  (gdb) file myfilesys  
  /.../ Reading symbols from myfilesys ... done.

Verilog Error: output or inout port "Q" must be connected to a structural net expression -

I get the error every time, I try to compile. I'm not sure why anyone can help is? I'm new to verilog.

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo
