我寫了一套flex和野牛的套評估程序。野牛集評估代碼錯誤
我面對的問題與錯誤
bison -d calc.y
flex calc.l
cc -o a.out calc.tab.c lex.yy.c -lfl

請幫我處理上面的錯誤，非常感謝！
以下鏈接是我在Gist上的代碼。
calc.l：gist.github.com/fbukevin/5662335
calc.y：gist.github.com/fbukevin/5662350
test.h：gist.github.com/fbukevin/ 5662533
的Makefile：gist.github.com/fbukevin/5662359
（我沒有足夠的聲譽造成兩個以上的環節，所以我摘下的 「http：//」）
如果行「flex -o calc.lex.c calc.l」無效。請嘗試「flex calc.l」。 –
請在線分享您的代碼 - 例如，我們不想下載您的檔案，解壓縮，打開文件等。 –
感謝告訴我這種用法。系統告訴我，我沒有足夠的聲望來構成多個鏈接，因此我刪除了「http：//」。 –
