Alright, I've decided to go with the Rom codebase. I've downloaded Rom24b6, and extracted the zip succesfully. However, when I run make, I also run into the following problem. Note this is not the first time either, I've run into this same exact problem on other codebases. Here it is.

That silly srandom thing. I just cannot figure it out. Any help would be greatly appreciated. Thanks.

Did you install the crypt lib as answered in your last topic?

And do you have -lcrypt on your L_FLAGS ?

Scratch what Samson said. He had the right idea, but it is the wrong place to put it. Look here:

Quote:
$(CC) $(L_FLAGS) -o rom $(O_FILES)


Currently, the option -lcrypt is contained in the variable L_FLAGS. The problem with that is gcc requires that the library *must* come *after* the object file which needs it.

In short, place -lcrypt at the end of this line and everything should link fine.

Totally Awesome! Finally, thanks to you guys, I got my rom up and running! Now I can get into the fun of porting my 17 smaug areas with over 200 rooms in each converted to run under rom! *Big toothy grin*

Special thanks to Raz, once I added that bit of code, it went well. Thanks to you all for taking the time out to offer advice, I've learned greatly from everyone. Thanks!

Or you could change the above to:

Quote:

$(CC) -o rom $(O_FILES) $(L_FLAGS)


And it would accomplish the same thing with -lcrypt on the L_FLAGS line.


Incidentaly, issues with crypt are why I resorted to getting the MD5 password code to work for this stuff. That way no more dealing with crypt and it's crap :)

Most folks who have actually provided feedback say they like it - especially when jumping back and forth between Cygwin and Linux pfiles.

True. However, it is probably best to do:


$(CC) $(L_FLAGS) -o rom $(O_FILES) $(LIB_FLAGS)


And add a variable called LIB_FLAGS with all the libraries that you wish to include. It seems that gcc has a weird system of parsing the flags as it goes left to right, so an option might not be turned on until it is read on the command line.

That was probably a good choice for another reason. You would have left Windows systems out of the loop since they do not have a similar function AFAIK. Packing a custom algorithm with IMC was a good idea in the long-run for maintaing and porting the code.
