I've worked my way through several issues so far (learning a bit about cygwin and installing make, c++, etc). I can get to the end (I think it's almost the end- I'm no programmer). It compiles everything fine but after finishing with weather I get an error that -lasan cannot be found. My research says it's some kind of address sanitizer for linking or something like that (see I'm not a programmer). My research also says there's none for windows. But I've seen on these forums that people have compiled this with cygwin on windows 10. Any suggestion or help? I wish I could just download an already compiled smaugFUSS. Years ago when I was on XP, I was trying to compile smaug 1.4a and never could. But I managed to get hold of smaug.exe somehow and was able to run my own mud. Trying to do so again and this is the wall I hit. Thanks for any help!

What if you remove -fsanitize=address from the W_FLAGS line in src/Makefile?

Hi- thanks for the prompt suggestion! I gave it a go and same error. So I did make clean and tried make again. Same error at the same spot. I really thought your suggestion was the fix! Here's the WFLAGS I have.

W_FLAGS = -Wall -Wshadow -Wformat-security -Wpointer-arith -Wcast-align -Wredundant-decls

That's with your suggestion removed and another section removed. Here's the original
W_FLAGS = -std=c++1z -Wall -Wshadow -Wformat-security -Wpointer-arith -Wcast-align -Wredundant-decls -fsanitize=address

The first part was removed as was suggested from a forum post I read.

Would there be any other references to the fsanitize in another file needing changed?

You tell me. Where did you get your smaug source from?

Since you're using Windows 10, any chance you could use Windows Subsystem for Linux instead of Cygwin?

I get an error that -lasan cannot be found.

I’m surprised you get this message, after making the suggested change. Why would the linker want to use the library libasan if there is no call for it?

Perhaps if you copy and paste the exact error message, including the surrounding lines, rather than just paraphrasing what it is.

Hi, thanks for both of your quick responses! I am also surprised it's calling for lasan. I downloaded the source from smaugfuss github.

Here is my exact error

Compiling o/weather.o....
/usr/lib/gcc/x86_64-pc-cygwin/11/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lasan
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:57: smaug] Error 1
make: *** [Makefile:46: all] Error 2

I can certainly try the subsystem linux. But I feel I've gotten so close here! lol

Hi again,

So I have finally compiled it (still had some errors). There was a fsanitize reference in L_FLAGS of the Makefile. I removed it and it compiled (I think that was the only issue). It did give the same lasan error at the end but it did say it completed compiling the mud and I have smaug.exe in src. Now when I run smaug.exe I got a bunch of dll files missing. So I was able to copy each of those into the src folder. Now it runs and disappears. Where do I type the nohup starup thing? Sorry if these are stupid questions. I do appreciate all of you guys' help!

If you got the same error again then it seems like maybe you didn't remove all of the invocations? I see yet another one in D_FLAGS.

Are you launching from the command prompt?

It runs and disappears? You mean, you double-click the .exe?

Make a command prompt (you get one with Cygwin), navigate to the folder and run it from there.

In fact you usually navigate to the area folder and run it from the source folder, ie.


cd <somewhere on your disk>/smaug/area
../src/smaug

Thanks again for everyone’s help! I finally figured it out. I needed to run in Cygwin from area folder using the ../smaug command. Worked perfectly! Thank you so much for your help!
