Hi,


Have you added the build rules to your project ? Open the property page for
the .y file in your project
and click on 'Custom build Step' node in the tree view . Enter
C:\...\bison -options example.y in 'Command Line', where
  ... is the path to bison.exe. You can put bison.exe and flex.exe
anywhere you like, as long as you specify the
path to the executables in the command line. You also need to specify the
output file in 'Outputs'. Bison will in your case
generate the files example.tab.c and example.tab.h unless you use the '-o
file-prefix' or '-d file-prefix' option.

Return to the comp.compilers page.
Search the comp.compilers archives again.
