我正在使用flex并bison构建一个我从Github克隆的简单计算器项目.
但在我输入make终端后,我收到以下消息:
gcc -o calc calc.tab.c lex.yy.c -lfl
calc.y:48:1: warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
main() {
^~~~
1 warning generated.
ld: library not found for -lfl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [calc] Error 1
我怎么能解决这个问题？
