swr 2.0 compile cygwin

ok im having a bit of trouble. I edited the makefile to be able to use cygwin. Im running off a winxp notebook. i keep getting this:

$ make
make -s swr
Compiling o/act_comm.o....
Compiling o/act_info.o....
act_info.c: In function `void do_password(CHAR_DATA*, char*)':
act_info.c:2551: error: `crypt' undeclared (first use this function)
act_info.c:2551: error: (Each undeclared identifier is reported only once for ea
ch function it appears in.)
make[1]: *** [o/act_info.o] Error 1
make: *** [all] Error 2

:Please help

There should be some flag in the Makefile where you uncomment it to disable crypt.

well i check the makefile and made the change's im still getting the:

$ make
make -s swr
Compiling o/act_comm.o....
Compiling o/act_info.o....
act_info.c: In function `void do_password(CHAR_DATA*, char*)':
act_info.c:2551: error: `crypt' undeclared (first use this function)
act_info.c:2551: error: (Each undeclared identifier is reported only once for ea
ch function it appears in.)
make[1]: *** [o/act_info.o] Error 1
make: *** [all] Error 2

my makefile is:

This line:

Remove the # in the second line.

ok i removed the # and im still getting the same error.

You shouldn't be. Try a make clean. Are you using SWRFUSS? If not, I suggest you should.

This means act_info.c has not seen a definition for what "crypt" means. Any file which produces this error needs:



at the top with the other includes when using Cygwin. This gets you the declaration for the crypt function.

Secondly you need to remove the # from in front of:


That will allow the compiler to link the crypt library once you're done. This requires that you have the crypt library package installed from Cygwin.

ok thanks that helped i got a clean make.

I get the same Error, even after uncommenting the Cygwin and Crypt lines. Here is my Makefile. I also don't have crypt.h anywhere on my computer. It'd be great to know where I can get it, and where it needs to be placed.

Nevermind, I had to get the right Makefil, I had an old version of the server, also, and was using two folders, haha. Sorry for the false alarm.

Ok that got ride of some of it but not i get a new message...

act_move.c: In function 'ROOM_INDEX_DATA* generate_exit<ROOM_INDEX_DATA*, EXIT_DATA**>':
act_move.c:604: erro: ISO C++ forbids cast to non-reference type used as lvalue

make[1]: *** [act_move.o] Error 1
make[1]: Leaving directory '/cygdrive/c/Phobos/swrip200/src'
make: *** [all] Error 2

thank you for helping with the crypt and would be greatfull if you can help with the message here also

Please copy-paste error messages, not just retyping them.

And once again, use search.
