Emerge does not work, so, I looked at the source.
Besides this error, wich is easy to fix:
| Code: | In file included from ../../include/salt/socket.h:32,
from socket_i.h:67,
from address.c:29:
../../include/salt/vtypes.h:127:4: #error "CPU unknown" |
I get:
| Code: | In file included from ./NotOSX/notosx_mdns.h:39,
from ./Posix/posix_mdns.h:34,
from Posix/posix_mdns.c:29:
./NotOSX/DNSServices.h:249: warning: division by zero
./NotOSX/DNSServices.h:249: error: storage size of 'dns_check_compile_time_249' isn't constant
./NotOSX/DNSServices.h:259: warning: division by zero
./NotOSX/DNSServices.h:259: error: storage size of 'dns_check_compile_time_259' isn't constant
|
This happens in gcc 3.3.3 and 3.4, so I guess it is amd64 specific. Anyone an idea? |

Well, since I didn't hear anything, I got to work on it myself. After changing some (unsigned) long's to (unsigned) int's, and making sure that x86_64 is recognised, howl wil compile and install. The problem is: it still does not work...
here is the diff to get it to compile (against 0.9.5):
| Code: |
57a58,61
> #if defined(__x86_64__)
> typedef int sw_long;
> typedef unsigned int sw_ulong;
> #else
59a64
> #endif
123a129,130
> # elif defined(__x86_64__)
> # define SW_ENDIAN 1
|
While compiling I get the following list of warning:
| Code: |
gcc -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE=\"howl\" -DVERSION=\"0.9.5\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_DLFCN_H=1 -I. -I. -I../../../include/ -I../ -g -O2 -c NotOSX/notosx_mdns.c -MT notosx_mdns.lo -MD -MP -MF .deps/notosx_mdns.TPlo -fPIC -DPIC -o .libs/notosx_mdns.lo

Might be because void pointers are 8 bytes on x86_64... and might also be why howl does not work yet..
Could somebody help me, I realy need it to work  |

this is a common problem with porting software to amd64. a pointer wont fit inside of an int on amd64, so casting a pointer to an int and the other way around wont really work. you can cast a pointer to a long... but you might not want to do that anyways. looks like you have a lot of debugging to do 
but you seem to already know that since you already changed some ints to longs... |

The recommended way to fix (32-bit) code that casts pointers to int's and performs arithmetic, is to instead cast the pointer to a (char *)
So it's as simple as going to each of the warning-generating lines, and replacing (int) with (char *) ... after that, cross your fingers.
