Just want to refresh and check to make sure I don't make a mistake, but I am spoiled now with my newer OS's, binary apps, etc. and helping out someone right now who has some old servers and some apps need upgrading like proftp, etc.

ALL apps are compiled, I have the old src folder, even the config.h file which if I clean the cobwebs will give me the config settings that were used right? Basically I want to do an in place upgrade from an old to new version and don't want to kill what's there, so I am assuming I can do a make with the config.h from the old compile and it should just build with those options, right?

Dusting the head off and just wanted to make sure ....
Thanks

Hi,

You're right. You can compile a newer version of a software using the ./configure options of the old one.
You can use config.h or config.log to find the options used to compile the old sources.
Sometimes there is also an executable script config.nice created, that you can copy and run in the new sources directory to configure it directly.

Note that until running "make install" nothing is installed, so you can test the new version of the app by running it from the sources directory. Of course you have to stop the old one prior doing this.

Regards
