Subject:	error: `::acosl' undeclared : #INCLUDE <cmath> and <fstream>
Date:	Fri, 22 Oct 2004 11:28:26 -0500
MIME-Version:	1.0

Hello,

I am compiling using the latest Cygwin.
My main.cpp starts with:
- - - - - -
#include <cmath>
#include <fstream>
#include <iostream>
#include <iomanip>
#include <sstream>
#include <stdio.h>
#include "ims/c4s/sa/tuf/Tracker.h"
#include "ims/c4s/sa/tuf/TrackInformation.h"
using namespace std;
- - - - - -
My Makefile has:
- - - - - -
OPTIONS = -Wall,--subsystem,windows -mno-cygwin -O2 -g -pedantic \
			-Wpointer-arith -Wcast-qual -Wcast-align \
			-Wwrite-strings -Wstrict-prototypes \
			-Wmissing-prototypes -Wconversion
	
INCLUDES = -I./
#INCLUDES += -IC:/cygwin/usr/include
#INCLUDES += -I/cygdrive/c/cygwin/usr/include

trackerTest: Main.cpp
	g++ $(OPTIONS) \
		$(INCLUDES) \
		-o trackerTest \
		Main.cpp \
		$(LIBRARIES)
- - - - - -
Compiling, I get a line:
   netinet/in.h: No such file or directory

I then then tried un-commented-out one of the #INCLUDES line
to get at the cygwin "netinet/in.h" file,
It is just:
- - - - -
#ifndef _NETINET_IN_H
#define _NETINET_IN_H

#include <cygwin/in.h>

#endif /* _NETINET_IN_H */
- - - - -
meaning that the useable version of in.h is:
   C:/cygwin/usr/include/cygwin/in.h

With that "fix",
4 errors are seen below (per error type, I am only showing you the 1st of many).
The "/usr/include/c++/3.3.3" is under C:\cygwin.

The #INCLUDE for <cmath> and <fstream>
seem to have problems with the latest Cygwin 3.3.3

Can you help?
