Root Folder doesnt detect .tar file

I recently uninstalled Cygwin, and reinstalled it. I went to place the .tar file for the code in my C:\cygwin\home directory, but when I did and opened up Cygwin and typed 'ls' it did not list the file. Any thoughts on why this is?

First I thought: Why isn't my named folder listed in C:\cygwin\home as C:\cygwin\home\Isaiah? There is no Isaiah directory.

Second I thought: Cygwin is listing the command prompt as Isaiah@MonolithMobile ~ ... maybe its looking for the Isaiah folder.

I don't know and I am stumped.

Okay. So the error as I discovered is in the current directory I was in. I typed pwd in Cygwin and found out I was somewhere in Java Land due to the fact that I had changed both my PATH and HOME system environments. Now, when I go to compile any source code, be it SMAUG or SWR, I get a flood of errors. An example is as follows:

$ make
make -s swreality
Compiling o/imc.o....
cc1: warnings being treated as errors
imc.c: In fucntion 'imcone_argument':
imc.c:368: error: array subscript has type 'char'

and another example error line it gives down the page is:

imc.c:2554 error: the address of 'url' will always evaluate as 'true'

Whats going on!? Thanks!

Normally cygwin makes a home directory and puts your home directory (ie. named Isaiah in your case) under that.

I suppose it depends how you installed Cygwin.

Possibly Cygwin (when you reinstalled it) is somewhere else completely. Try firing up cygwin, and typing: df -h

In my case I see this:


$ df -h
Filesystem            Size  Used Avail Use% Mounted on
C:\cygwin\bin          32G   30G  1.8G  95% /usr/bin
C:\cygwin\lib          32G   30G  1.8G  95% /usr/lib
C:\cygwin              32G   30G  1.8G  95% /
c:                     32G   30G  1.8G  95% /cygdrive/c
x:                    912G  272G  641G  30% /cygdrive/x
y:                    912G  272G  641G  30% /cygdrive/y
z:                    932G  585G  347G  63% /cygdrive/z

$ pwd
/home/Owner


The third line down ties together the "root" Cygwin directory named / to the folder under Windows which is C:\cygwin

Typing "pwd" shows that my home directory in Cygwin is /home/Owner

So that folder in Windows would be:


C:\cygwin\home\Owner


However that is for *my* installation, if you installed Cygwin somewhere else, all that might be different.

As for the errors, the gcc compiler has tightened up a lot of the checks, maybe by reinstalling you have a version that is more strict.

Thanks a bunch, Nick. But here comes another question at you. If in my re-install the gcc I selected is restrictive, how is one to know what is an appropriate version of gcc to use for my purposes in getting this MUD up and running? The version of GCC that was installed was in the Cygwin setup, yes?

By the way, how are you able to select, copy and paste from Cygwin as you do? I have had to type everything thus far. Thanks again for your help. Love those youtube videos you have up. I just discovered em'!

Nick, I found this post/thread via Google in searching for a solution to my problem.

http://www.gammon.com.au/forum/bbshowpost.php?bbsubject_id=8655

Given the information in this, what do I need to do to supress the warnings (instead of having to change code)?

Or should I just roll back my version of GCC to something below 4.2?

Click on the system menu (top LH corner) and then you can select Edit -> Mark (from memory), then click in the window to select text, then hit Enter to complete the selection and copy to the clipboard.

One of the command-line options turns errors into warnings (-Werror or something like that) so you could take that out, and then they are just warnings.

Or, work out what the warning is (see man gcc) and add the -Wno-whatever to the make.

How do you use -Werror? Is it used with make (i.e. make -Werror)? Or where is it applied?

Ive looked all over the net and nothing really comes up on it or how to use it. Thanks for the help, again.

Okay, disregard the post above. I removed -Werror from the makefile, and I ran make on the .c files. This displayed the errors but continued anyway. However, when I ran the executable "swreality.exe" the process started...

And then it stopped there. Now why would there be a problem with reading area files?

The funny thing is, not too long ago, I had just installed this version of SWRFUSS, compiled it and ran it on Cygwin, so its a little strange to see it not working now.

Stopped with an error message? Or just went into a CPU loop? Or hung doing nothing? Time to use gdb to find what it is doing.
