Re: [gentoo-embedded] Error compiling sox (for asterisk) on a arm platform (nslu2)

[Christopher Friedt]

It's a math function - the natural log in float format. It should be 
included in libm but since you're linking with -lm and still getting the 
error, I would assume that the math library in your uclibc has a feature 
missing or something.

You may have to upgrade the uclibc version.
