perl-5.14.0 compilation in new GCC does not pass the workaround

1?? ? Because in the new version GCC divides the standard library in the C99 into the libc and LIBM two parts, LIBM contains some mathematical libraries, etc., if you want to use LIBM, you must add the-LM option

After extracting configure, and then in Makefile, Ldflags and cldflags two parameters plus-lm can solve the problem

2?? ? Reference: Http://serverfault.com/questions/145288/make-error-when-compiling-perl-5-12-1-rhel-5-5

??? Modify Dist/io/poll.h: Modify the #include to #include

3?? ? Reference: HTTP://BLOG.163.COM/ZHANGLIYE_2009/BLOG/STATIC/1223120282013518104148904/

In Makefile, the Ldflags and cldflags two parameters are followed by a-LRT?
