I am having a hard time getting Ubuntu's gcc to understand the
long double-manipulating functions from math.h, namely
cexpl. The message I get for all of them when compiling is
undefined reference to `sqrtl'
Is there any flag other than
-lm that I have to put on the command line for gcc to understand these functions? Is it a missing package? Or is this a problem with the version I'm using (4.6.1 on Oneiric)?
