long double math functions support
by Alex Potapenko 11 Nov '15

11 Nov '15

While trying to build lcd4linux, rev. 1203 (https://ssl.bulix.org/svn/lcd4linux/trunk) I encountered undefined reference to log2l issue. I'm using uclibc-ng 1.0.6, and I see only these two math-related configs: > DO_C99_MATH=y > # DO_XSI_MATH is not set Obviously, DO_XSI_MATH is unrelated here, since it stands for Bessel functions. Clearly, uClibc-ng (at least, as of 1.0.6) is missing log2l (and probably other long double math functions). As a workaround, I added -Dlog2l=log2 cflag, and lcd4linux builds fine now, but I was wondering whether it is possible to have these functions in uClibc-ng. Thanks, Alex
