compiler error - please help

it's been about a year since i've looked at my code here. apparently when I left the project last year, i left it with compiler errors and am having problems determining what the cause is and how to fix it.

any direction on how to solve this problem would be greatly appreciated. let me know if any other bits of info are needed. Thank you - Nargs

smaug 1.4 - compiled on cygwin

here is what I am getting when I make all:



and those "error: dereferencing pointer to incomplete " keep repeating over and over many many pages long. Those problems will probably be fixed once my main problem is rooted out. which apparently is in mud.h


mud.h extract:
2288 MPROG_ACT_LIST * mpact;
2289 int mpactnum;
2290 sh_int mpscriptpos;
2291 MOBF_INDEX_DATA * pIndexData;
2292 DESCRIPTOR_DATA * desc;
2293 AFFECT_DATA * first_affect;
2294 AFFECT_DATA * last_affect;

Is 'MOBF_INDEX_DATA' a typo for 'MOB_INDEX_DATA'?

wow - that was an easy one for you and now i feel sheepish. lol, thanks :)

i fixed that last error and am now getting a legion of new problems :(

is there one single thing i should look for or one thing that would fix the problem? I would not have made this many changes without testing.

They seem to be mainly warnings, I think the compiler warnings have been improved.

You have about 3 main errors I can see, re_exec (I think that is called in one place and can be removed - search the forum for that).

Similarly for crypt, search the forum.

I am not sure about RENAME, but I would look at where it is defined, maybe that can be spelt differently or something.

i uncommented the appropriate 2 lines in makefile but still get the same errors.

what i dont understand is i have 2 versions of my code.
the 1st version - wont compile due to errors noted above.

2nd version - backup version of the 1st version. probably month before 1st version current state.



2nd version compiles cleanly - no warnings whatsover about ambiguous else if whatevers and nothing about regex rename or crypt references.



why would one report the else if ambiguous problems and the other not if they're using same compiler? the code it gives the warnings on is not my code. in one place its auction code and i've never messed with that in my life.

Why isnt it consistent? and any other ideas on the crypt regex thing?
