winstub.c needs to have the 1st argument type in getnetbyaddr changed
to uint32_t to build on cygwin
I'm guessing the cygwin headers have changed because net-snmp used to
build for me with no problems on cygwin. But now I get the same error
all the way back to version 5.6.1:
libtool: compile: gcc -I../../include -DNETSNMP_ENABLE_IPV6
-fno-strict-aliasing -g -O2 -Ucygwin -Dcygwin=cygwin -c winstub.c
-DDLL_EXPORT -DPIC -o .libs/winstub.o

SYNOPSIS
#include <netdb.h>
struct netent *getnetbyaddr(uint32_t net, int type);
struct netent *getnetbyname(const char *name);
struct netent *getnetent(void);
winstub.c has
#if (defined(WIN32) || defined(cygwin) || defined(aix4))
...
#if HAVE_NETDB_H
#include <netdb.h>
#endif
...
struct netent *
getnetbyaddr(long net, int type)
{
return 0;
}
So I tried changing "long" to "uint32_t"
struct netent *
getnetbyaddr(uint32_t net, int type)
{
return 0;
}
and it builds with no errors. "make install" had some permission
problems, but I finally got them straightened out:
