The configure script can not find an acceptable C compiler in your path. Samba needs to be compiled for your OS by a C compiler. Depending on what OS and what level of installation you used, you may or may not have an acceptable C compiler. You can email my alias with your OS version and rev level (ex. Solaris 2.6) and I will tell you what directory to check and what file to look for to see if you have an acceptable C compiler. If you do you can just add it to your path and you should be allset. If you don't have an acceptabe C compiler, the best thing will be to download gcc (its free) and I can also give you the step by step on how to download and install that.
So just email cpfeiffer@vsc.teksystems.com with your OS type and version and I'll get back to you.
