Newbie question - The instructions to get .net rules appear to be 
straight-forward, but it doesn't appear to be working.  


I've followed the install and configure instructions:

./bootstrap.sh
./configure --dotnet
make
make install

ar -t /usr/local/lib/libyara.a shows dotnet.o in libyara.a

However, when I'm trying to compile a rule in a file that just has "import 
dotnet" at the top. I get compiler error no 34, which I believe is "
ERROR_UNKNOWN_MODULE". 

      compiler->last error is 34
      compiler->last_error_extra_info is do
      compiler->last_error_line is 1  [the line that says "import dotnet"]

Code is

****
int  main(int argc, char **argv) { 
 
  int result = 0; 
 
  /* Initialize libyara */ 
  result = yr_initialize(); /* returns int */ 
  printf("initialize result: %d\n",result); 
 
  /* Create new compiler instance. */ 
  result = yr_compiler_create(&comp_ctx); 
  printf("compiler instance: %d\n",result); 
 
  /* Load rule file, and compile it. */ 
  FILE *rule = fopen(YARA_CHAT_RULE, "r"); 
  result = yr_compiler_add_file(comp_ctx, rule, NULL, YARA_CHAT_RULE); 
  printf("compile error on entry : error no.: %d\n",comp_ctx->last_error); 
  printf("compile error on entry : error info: 
%s\n",comp_ctx->last_error_extra_info); 
  printf("compile error on entry : error line: 
%d\n",comp_ctx->last_error_line); 
  printf("no. compile errors: %d\n", result); 

 ****

Creating the compiler returns 0

Any reason why I can't get the dotnet module to be recognized?
