All, There really is a question at the end... Sorry for the length. My goal is to run NS-2 on a non-network connected Pentium 4 box. I have downloaded the ISO install for Fedora 10. It has installed (appears to be running correctly). I have downloaded the ns-2 all in one package. I've built it in the past on a windows box, but was unable to get the environment variables set up correctly to run it. This is my motivation for going to the stand alone system. I hope to be able to have complete control over the environment without the Windows system interfering. The ns-2 installation script is failing to build the package correctly. I think it is because I don't have my environment set up correctly. It does not seem to be finding the c compiler. I have built a hello.c file and updated these environment variables: PATH has been extended to include: /usr/libexec/gcc/i386-redhat-linux/4.3.2 and . C_INCLUDE_PATH has been added as: /usr/lib/syslinux/com32/include LIBRARY_PATH has been added as: /usr/lib/syslinux/com32/include I'm sourcing the setup script and checking the new setting w/ env. At a terminal prompt (under a user account) I type gcc hello.c It seems to be finding the compiler, but not the include files or libraries of some kind. I get the following: fileno fdopen fclose fread fwrite fflush main Execution times (seconds) followed by a table of compiler results. I do not get an a.out file. Finally a question. Assuming my diagnosis of environment variable mistakes is correct, what are the correct environment variables to set and set to what? Is there a c compiler included in the ISO fedora 10 disk install? Should I be building gcc? That seems to need a c compiler too. I have downloaded that package and tried, but failed with similar results. If I'm way off base, please point me in a new direction. I appreciate any help I can get.
