DDE socket() include

Edit: I solved this by adding #include “sys/types.h” before my includes, and putting ${UNIXLIB} ${INETLIB} ${SOCK4LIB} on the end of my LIBS.

Hello, I want to use socket() etc. in my module. I’ve got a test which builds fine with !GCC – I didn’t have to change my makefile at all, I just put the includes in. But in DDE I don’t know how to make it work.

These are the errors I get…

Errors in file:  TCPIPLibs:sys.h.socket

    Line  Type           Description
      48  Error          declaration lacks type (assuming 'int'): 'u_cha
      48  Error          expected ';' or ',' - inserted ';' before 'sa_f
_t'
      48  Warning        extern 'sa_family_t' not declared in header
      48  Error          declaration lacks type (assuming 'int'): 'sa_fa
t'

followed by loads more.

This is my Makefile.

COMPONENT      = AModule
CMHGDEPENDS    = module
INCLUDE_OSLIB ?= -IOS:
CINCLUDES      = ${INCLUDE_OSLIB} -ITCPIPLibs:,C:
LIBS           = ${OSLIB} ${ASMUTILS}
OBJS           = module socktest other_objects
HDRS           =
ASMHDRS        =

include CModule

C_WARNINGS = -wp

and these are the includes

#include "sys/socket.h"
#include "netinet/in.h"
#include "netdb.h"

The includes are coming from the export from the OS source tree.

If you are using SOCK4LIB you need

LIBS += ${NET4LIBS}
CDEFINES += -DCOMPAT_INET4

but to use SOCK5LIB – the default – you just need

LIBS += ${NET5LIBS}

NET4LIBS or NET5LIBS replace the libs you mentioned in your edit.

That makes things simpler. Thanks!
