I'm using mingw to compile the Shakespeare Programming Language and during the compilation I get the following error.

c:/users/neil/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe:
cannot find -lfl
collect2: ld returned 1 exit status
mingw32-make: *** [spl2c] Error 1

I searched it in Google, and found a few people have trouble ld.exe but most of them were having issues with other flags and could not find anything useful. What does the -lfl flag do, and how can I fix this issue? EDIT: I have downloaded the flex binaries from http://gnuwin32.sourceforge.net/ and added them to my path.

Here is my Makefile:

他のヒント

Adding flex to your PATH won't make the flex library available to the linker, ld.exe. You may need to add the flex library directory to an -L <directory> command line option to your compiler.

try -LC:\pathtoflexlibdirectory where libfl.a file is
