Description Youngki KIM CLA 2011-05-27 03:59:00 EDT 
when I use math library functions such as sqrt() and sin() with variables, eclipse shows me error message "undefined reference to 'sin'".

sin(100); ==> OK

float a;
sin(a); ==> error "undefined reference to `sin'"

Please open bugs with CDT. This has nothing to do with Eclipse's plug-in for Apache Ant.

The parser does not provide this kind of error, it is emmited by your linker.

I agree with your comment. This morning I updated my packages in Ubuntu 10.04 and the error's gone.
