Hi everyone, I intend to compute power of x to y, whose type is float. It works well with TOSSIM by using pow function. Unfortunately, when I compile in telosb, it complaints "app.c:(.text+0x4486): undefined reference to `pow'". And I find in the archive<http://www.nabble.com/Regarding-pow-and-sqrt-td18204383.html>that this could be solved by "using '-lm' compiler switch". How could I actually do that to tell the compiler to link against math library? Thanks.
