I'm glad that worked!
With SlickEdit, you have 3 options for builds:
1) Let SlickEdit do them,
2) Let SlickEdit generate and use an external makefile, and
3) Use a user-written makefile.
These options are accessible from Project > Project Properties, then click on the Build tab. The Tools tab allows you to configure the command line for the Build, Rebuild, Compile, and other options that appear on the Build menu.
Which you choose depends on how the rest of the team does a build and what compiler and linker you are using. If everyone is using SlickEdit--the most natural choice
--then you may choose option 1. If other members of the team are using different editing tools, selecting option 3 will allow your team to produce builds in the same way, one of the most import success criteria in my opinion.
Unless the Fujitsu compiler is a derivative of GNU, SlickEdit doesn't have any built-in support for it. If it is, create your project by selecting Project > New and then select the GNU C/C++ Wizard from the list of project types. Otherwise, select "(None)", and you'll have to configure everything yourself.
Assuming you went with the None option, you are probably better off using an external make system. Once you have created your make files, use the Tools tab to configure the command line for the appropriate build operations.
For post build operations, like "executing a downloader", you can either make this another step in your makefile or use SlickEdit to define a post-build command, on the Build tab.
This isn't a comprehensive solution to your question, but it should be enough to get you going. Good luck!
