Larry, Thanks, for your quick reply. I'll consider PHP in the future, but right now, I've got dozens of programs I've written in C for cgi on an apache server that is runing on a windoze environment and I'm trying to convince my boss to switch to hosting on a ts-7500. His answer is "well will it run our current software?" and he is not interested in re-writing stuff in PHP. I might be able to run new stuff in PHP, but for now I have to demonstrate that his old C programs will run lock stock and barrel using gcc on the deby linux ts-7500. the old windows environment ran straight C programs that were compiled with the borland 5.5 C compiler. Here is a snippet: /***********************************************************************\ lostproduct.c #NAME? "starting point.

Now I need to ??? configure??? Apache so that cgi executables will run from ??? directory ??? (/usr/lib/cgi-bin ???) and configure the apache to recognize that the files with the extension .cgi are allowed to be run??? I read things about httpd.conf, but then I read about default vs virtual ... its all so confusing. I wouldn't mind a hello world php program to get the apache stuff worked out, but I also need to compile and link my lostproduct.c into a a.out that I rename to lostproduct.cgi (or lostproduct.exe as I did in windoze) and get it to run on the TS-7500. I realize the #define's to the databases and directories and such will have to change, but I can live with that. Any help in getting this working will be appreciated. - jleslie

I would suggest a different design. This is exactly what PHP is
perfect for.
If it's not already on your board, you can add PHP as a module for Apache, or compile it in. You will learn to love PHP. You can write scripts that use syntax very similar to C, but it is actually interpreted, no compile required. You embed script right into your web pages. Good luck Larry On 9/24/2013 10:47 PM,
