I tried to install MQ2 on a second pc tonight, and got the same errors. After searching the boards for quite a bit and finding nothing I deleted my folders and unzipped a copy I had downloaded 02/25/04..... compiled with no errors the first time.

That's just because we're missing a file, I believe. There are functions being called that don't exist except in mq2spawns.cpp, which I couldn't find in the zip. It's not a big hairy deal, just delete the folder, get the backup you made of your old folder(you DO make backups, right?!) and wait for the zip to be fixed.. OR, try to snag mq2spawns.cpp from the CVS(haven't checked it yet.)


Edit: And apparently I was very wrong. The file DOES exist, I found it after I redid my search. Hmm... We'll see what comes of it, but for now, just use the older source.

yeah it appears to be in the cvs, i'll try to compile it with mq2spawns.cpp brb

ok i know, but unfortunately my old source is really really old(mq1), I'll just have to wait for the update :lol:

Add MQ2Spawns.cpp to your MQ2Main project, sorry for the confusion

/me looks around for the beating stick to give Amadeus a beating :)

Mothereff.. I was on the right track, just poking my nose into the wrong hole.

OK, not sure if this change was intentional. I always had commented out

Code: Select all

 #define DBG_SPEW
in mq2utilities.cpp and had no problems.

Now, if I do the same with the latest zip, I get the following errors:

Code: Select all

..\MQ2Main\MQ2Utilities.cpp(73): error C2065: 'szOutput' : undeclared identifier
..\MQ2Main\MQ2Utilities.cpp(73): error C2070: ''unknown-type'': illegal sizeof operand
..\MQ2Main\MQ2Utilities.cpp(73): error C2501: 'memset' : missing storage-class or type specifiers
..\MQ2Main\MQ2Utilities.cpp(73): error C2365: 'memset' : redefinition; previous definition was a 'function'
..\MQ2Main\MQ2Utilities.cpp(73): error C2078: too many initializers
..\MQ2Main\MQ2Utilities.cpp(74): error C2059: syntax error : '}'
..\MQ2Main\MQ2Utilities.cpp(74): error C2143: syntax error : missing ';' before '}'
..\MQ2Main\MQ2Utilities.cpp(74): error C2059: syntax error : '}'
..\MQ2Main\MQ2Utilities.cpp(76): error C2143: syntax error : missing ';' before '{'
..\MQ2Main\MQ2Utilities.cpp(76): error C2447: '{' : missing function header (old-style formal list?)
I looked and compared the code in the previous zip I had and this one and see some minor changes to VOID DebugSpewAlways(PCHAR szFormat, ...) but there is now a line of code that was not in the previous code, and seems to be causing the errors if I comment out #define DBG_SPEW:

Code: Select all

memset(szOutput, 0, sizeof(szOutput));
Everything compiles with no problems if I do not comment out #define DBG_SPEW so will just do that for now until I am either lambasted or someone figures out what is going on :)
