I'm learning C programming using the GNU toolchain (gcc, as, ld, glibc) using a popular linux distribution. What I expect from what I have read so far, is that if I use a function from the math library without specifying the library on the gcc, command line, is that I should get an "undefined reference" error message. I am not getting the expected error message, the simple application compiles and executes correctly. Can anyone explain why I am not getting the expected error message? Best regards, Harvey
