Re: wstring support in GCC 4.1.2 in Cygwin 1.5.25-11
How about minGW? Did you try that? I have similiar
problem and I will try to see if there is any
difference.

does Cygwin support wide char?
Does Cygwin support wide char? If yes, which package i should install? I cannot build boost on Cygwin due to no wide char support on my current Cygwin installation. thanks, -- 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/
Cygwin = cross platform (one way)?
I don't know if this question should be asked here or not. I have a small socket server application running on Linux. It uses Unix socket libraries and also do some file operations. I am wondering if I can compile it with Cygwin without any changes on my code? If yes, that means Cygwin is kind of tool to make an application being cross platform from Linux to Windows? So it cam replace ACE and Boost for those start from Linux? Please just send your comments to me if any if this question should not be posted here. thanks, James -- 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/

Re: please help
Thank you for your help. I have successfully eliminated those two error messages. They were caused by the ACE make include files. In those include files, there are some checking for library, such as PLATFORM_AIO_SUPPORT := \ $(shell test -e /usr/lib/librt.so && echo -DACE_HAS_AIO_CALLS) I commented out those checking related to librt.so* then those error message went away. I don't know whether Cygwin should include those lib or ACE should remove those checking. Anyway, a progress was made. thanks, --- "Larry Hall (Cygwin)" <[EMAIL PROTECTED]> wrote: > Longyu Mei wrote: > > Great!

RE: please help
Great! I see friends are here now. Let me tell you the entire story. We have a Linux application without any GUI. We used ACE (for socket) and boost for portability. It is a product now. We did not build it on Windows before even we plan to do that. Now we try too see if we can build and run it on Windows machine. I did a little research and then decided try CygWin first. I used the setup to download and install CygWin. I copy the entire project tree from source control onto my XP machine. Then I start the CygWin by click the Cygwin icon and cd to my source directory and tried "make clean" as I did on Linux machine. The first two lines are the error messages I mentioned on my previous email. I did do any system environment variable configuration which is not required. The issue is why that librt.so is required and why there is no such file under the installation. I have installed ALL packages. thanks James -- 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/
Re: please help
Thank you for your email. Now I know I am on the list. Yes, I use the setup.exe from the Cygwin.com and let it help me download and install all those packages. I started from those default packages. Then Devel category and finally I have installed ALL those packages (2.66GB on my machine). I cannot build my application. that is the first step to port that linux application to windows. Could you please check if your /usr/lib directory has that librt.so file? it will link to the /lib/librt.so.1 file. thanks --- Richard Ivarson <[EMAIL PROTECTED]> wrote: > Longyu Mei schrieb: > > > Please at least reply once and let me know I am > really > > on the mailing list. > > I can see your message (it's the first from you, > however, at least for me). > > Unfortunately I don't know a solution to your > problem. > Did you download the small Cygwin.exe, start it and > then let install your > needed packages with it? > > -Richard > > > -- > 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/ > > -- 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/
please help
This is my third email onto the mailing list. I don't know if I did something wrong because I can only receive email from other people but never get reply on my email. I need your help on Cygwin. After two days' effort on my WindowsXP machine, I still got message saying "ls: cannot access /usr/lib/librt.so*: No such file or directory" and "ls: cannot access /lib/librt.so*: No such file or directory" when I tried to make my application which was coding and running on Linux. I have download and install ALL Cygwin packages on my machine. I checked that "/usr/lib" directory and "/lib" directory, there was no "librt.so*" there. I have no idea what I can do next. I did anything wrong or the current Cygwin is missing something? Please at least reply once and let me know I am really on the mailing list.
