To install tpasm, just type make In the outermost directory. Then, assuming it compiled properly, you will have an executable called "tpasm" (also located in the outer directory). If you want to place it into /usr/local/bin, you can type: make install That's it :-) If you experience any problems during the build, or any warnings from your compiler, please email to let me know. Thanks. NOTE: There is a directory called "include" in the tpasm source tree which contains header files which are useful for various processor families. Currently, none of these files is installed anywhere when you issue "make install". Todd Squires squirest@ct0.com
