- Organization: FhG-IIS-A
Hi,
i am trying to build the new FreeBSD stack for my MPC860T based target,
but it does not compile! My last CVS update was on June, 28.
I cross checked it with the viper-target from the CVS-Repository and got
the same error: The Compiler (gcc 2.95.2) could not find the definition
of errno in getproto.c.
Here is what i did:
Using Windows Configtool 1.3.net, i selected template A&M Viper
then i added the packages
FreeBSD stack,
Networking and
Common ethernet support
The Configtool proposed the following solutions for various conflicts,
which i accepted:
CYGPKG_NET_DHCP Disabled
CYGPKG_NET_TFTP Disabled
CYGBLD_ISO_NETDB_SERV_HEADER Enabled, <net/netdb.h>
CYGBLD_ISO_NETDB_PROTO_HEADER Enabled, <net/netdb.h>
CYGBLD_ISO_BSDTYPES_HEADER Enabled, <sys/bsdtypes.h>
It remained one conflict: CYGPKG_NET_FREEBSD_STACK requ. CYGPKG_IO_FILIO
Therefore i added the package Fileio and accepted the following:
CYGBLD_ISO_NAME_MAX_HEADER Enabled, <cyg/fileio/limits.h>
CYGBLD_ISO_OPEN_MAX_HEADER Enabled, <cyg/fileio/limits.h>
CYGBLD_ISO_DIRENT_HEADER Enabled, <cyg/fileio/dirent.h>
I saved this configuration without changing any default settings
When i tried to build the target lib the following error appeared:

Did anybody else get the same problem - any ideas?
Thanks in advance
Wolfgang
PS: I tried it with the OpenBSD stack and it worked perfectly! The
include-file <sys/param.h> is different for Open- and FreeBSD and in the
OpenBSD version errno.h is included.
