New Cygwin installation
Hello, I updated my old cygwin installation with a newer one this week, I use cygwin in combination with a grafical development environment called Dev-Cpp. In the old installation it was sufficient to set up the c-include paht with c:\cygwin\usr\include and the c++-includes with c:\cygwin\usr\include and c:\cygwin\usr\include\c++. But now there are a lot more directories so called ..\c++\3.3.1\backward and ..\c++\3.3.1\i686-pc-cygwin. So I want to know wich directories I have to enlist in the include section of my dev environment. By now I have a misterious warning: 2 C:\usr\include\c++\3.3.1\backward\backward_warning.h:32 #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the X header for the X.h header for C++ includes, or sstream instead of the deprecated header strstream.h. To disable this warning use -Wno-deprecated. The project I tried to compile compiled successfully with the old installation of cygwin. for your referenz I will include my complete error messages and my include part of the project. I hope somebody will help me. Thanks in advance Frank -- +++ NEU bei GMX und erstmalig in Deutschland: TÜV-geprüfter Virenschutz +++ 100% Virenerkennung nach Wildlist.

RE: New Cygwin installation
Hi Dave, first thanks for your fast reply. I replaced the #include ostrstram with #includesstream but the type ostrstream type is still unknown. By commenting out the following lines // ostrstream stmPort; //stmPort /dev/com devnum : ends; // stmPort /dev/com devnum ends; // schnittstelle = stmPort.str(); and replacing it with: schnittstelle = /dev/com2; my application compiles very well. So must I throw away all my old books about C++ or what can I do to compile my older programs like they are? Greetings Frank -Original Message- From: cygwin-owner On Behalf Of Frank Wagner Sent: 17 March 2004 09:03 Hello, Hello. I updated my old cygwin installation with a newer one this week, I use cygwin in combination with a grafical development environment called Dev-Cpp. Never heard of it. In the old installation it was sufficient to set up the c-include paht with c:\cygwin\usr\include and the c++-includes with c:\cygwin\usr\include and c:\cygwin\usr\include\c++. But now there are a lot more directories so called ..\c++\3.3.1\backward and ..\c++\3.3.1\i686-pc-cygwin. So I want to know wich directories I have to enlist in the include section of my dev environment. The default search paths should be set up fine already, as long as you make sure to use gcc.exe for compiling C and g++.exe for compiling C++ files. The only directories you should need to include in the dev environment are those with your own application's headers. By now I have a misterious warning: 2 C:\usr\include\c++\3.3.1\backward\backward_warning.h:32 #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the X header for the X.h C++ header for C++ includes, or sstream instead of the deprecated header strstream.h. To disable this warning use -Wno-deprecated. Doesn't seem mysterious to me, but then again English is my first language. It's telling you about the fact that the C++ standards committee decided to change all the header file names a while ago, and the original header names are all considered out-of-date now. The project I tried to compile compiled successfully with the old installation of cygwin. If you've been making your own include paths in the dev environment by hand, you might well have got some directories in the wrong order and caused this sort of error. OTOH something could have changed in the C++ headers in a backwardly incompatible way, and the warning is to let you know to modify your code. Let's take a look at your errors: snip g++.exe -D__DEBUG__ -c cpx_mon.cpp -o cpx_mon.o -IC:/cygwin/usr/include -IC:/cygwin/usr/include/c++ -IC:/cygwin/usr/include/c++/3.3.1/backward -IC:/work/Sonstiges/priv/projekte/Software/include -ansi -g3 snip That's where you've tried to put your own include paths in there. You've most likely got them in the wrong order. The backward compatibility dir probably ought to be very last in the search order, but leave it to g++.exe, which knows what order to put them in already - take a look at the output from g++ -print-search-dirs. Take out all the include dirs except for your own C:/work/Sonstiges/. directory. snip In file included from /usr/include/c++/3.3.1/backward/strstream:51, from C:/work/Sonstiges/priv/projekte/Software/include/posix_terminal.h:21, from cpx_mon.h:25, from cpx_mon.cpp:9: /usr/include/c++/3.3.1/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the X header for the X.h header for C++ includes, or sstream instead of the deprecated header strstream.h. To disable this warning use -Wno-deprecated. In file included from cpx_mon.cpp:9: snip Possibly your posix_terminal.h has a #include strstream.h that should be changed into #include sstream, as the warning suggests; or perhaps your posix_terminal.h is correct, but the wrong header file is being found because you got the search path order messed up. The problem should disappear once you sort that out. cheers, DaveK -- Can't think of a witty .sigline today -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/ -- +++ NEU bei GMX und erstmalig in Deutschland: TÜV-geprüfter Virenschutz +++ 100% Virenerkennung nach Wildlist.

funktion itoa
Hello, I need to convert a integer to a string and in this case I want to use the itoa funktion call. I found a description of this funktion that explains: char * itoa ( int value, char * buffer, int radix ); Wich is defined in stdlib.h. When I try to compile I get the follwing error: implicit declaration of function `int itoa(...)' My function call looks like: itoa(B-anzahl, menge, 10); When I look into stdlib.h will find the following line: int _EXFUN(atoi,(const char *__nptr)); Here it is defined with a int as return value. What is my description wrong and how must I use this funktion? Thanks a lot in advance Frank -- COMPUTERBILD 15/03: Premium-e-mail-Dienste im Test -- 1. GMX TopMail - Platz 1 und Testsieger! 2.

Warning Message _WinMainCRTStartup
Hello, I compiled FLTK under cygwin and got the following warning multiple times. /usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/../../../../i686-pc-cygwin/bin/ld C:\usr\i686-pc-cygwin\bin\ld [Warning] cannot find entry symbol _WinMainCRTStartup; defaulting to 00401000 FLTK is a GUI library for different platforms. In spite of these warnings the compilation was successfull and it's possible to use these GUI library. But if I compile a own program with this library I also got these warning in my compiler output. What did I wrong and how can I avoid this? Thanks al lot Frank -- +++ GMX - Mail, Messaging more http://www.gmx.net +++ NEU: Mit GMX ins Internet.

Devicename conventions
Hello, does someone know wether there exists a document where I can find the devicename differences between windows and Linux/Unix. For example: To program the serial port with Cygwin the devicename for Windows must be /dev/com1 and on Linux /dev/ttyS0. So I want to know which names the other devices should have for example the keybord? Is there a document where I can read this or doesn't this make any sense? Can I also try the Linux conventions?

Error after ./configure
Hello, I tried to build insight5.1 on a WinNT 4.0 maschine. After the command ./configure I got the following messages: Configuring for a i686-pc-cygwin host.
