Hi All,
I have legacy code (part A) written in Posix API that I want to
port to Windows, and there is also some other necessary code (part B)
written in Win32 API, but seems that I cannot use GCC on Cygwin to
build them (A and B) together to get the executable program, since I
met issue like "header missing" for Win32 API .
Is there any other method to resolve such problem? I considerred
to build part B as dll first and build with part A on Cygwin. Is that
okay?
Thanks a lot for your guidance!

And before you answer that, you do aware, that mixing POSIX and Windows native API calls is generally considered not a very good idea, right? Depends on the kind of mix (stirred, not shaken?), you may be on a very sharp edge of things. Without looking at your code, one possible solution is to push all platform-dependent code into a separate library, and load it at runtime. -- WBR, Andrey Repin (anrdaemon@yandex.ru) 24.02.2014, <13:49> Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple ^ permalink raw reply [flat|nested] 3+ messages in thread

Actually the code is historic legacy, and I want to have a quick try on Windows and reduce the efforts as much as possible. Code part B mainly contains some device operations, like serial port, ethernet config(not only socket), USB detection, etc, code part A mainy contain process management and FS operation, etc. I get "no tchar.h", "definition of gethostname conflicts" like error when I build them together on Cygwin using GCC. What is your advice under such situation? "Push all platform-dependent code into a separate library" is another method I'm trying for long-term resolution, but is there any approach I can have a quick try w/o stbility and performance consideration? Thanks a lot and appreciated for your reply! 2014-02-24 17:55 GMT+08:00 Andrey Repin <anrdaemon@yandex.ru>: > Greetings, Qw Liu! > >> I have legacy code (part A) written in Posix API that I want to >> port to Windows, and there is also some other necessary code (part B) >> written in Win32 API, but seems that I cannot use GCC on Cygwin to >> build them (A and B) together to get the executable program, since I >> met issue like "header missing" for Win32 API . >> Is there any other method to resolve such problem?
