Yes, in Cygwin you usually configure a project for a real Unix target. Sometimes you set some flags that this it "not win32" to avoid MS-specific non-Posix settings. I think, UHD should be Cygwin-compatible in principle (when it's not using raw sockets). I could compile it but some binaries crashed with a core dump. Sorry, I deleted the directory later, so I can't provide you a crash report now. Perhaps later for a next try. In general I think Cygwin should be a supported platform for UHD, because it's a GNU "operating system", without GNU kernel, but with almost all the rest of GNU.

Maybe? I had much of this mixing experience in Matlab. It's a horror. You can't really connect these two worlds, because the Cygwin gcc uses a different exception handling system as Windows programs. The runtimes are not compatible. Trying to connect binary code via DLL, especially external MEX-functions in MATLAB, will lead to mysterious crashes. I'm using gcc to compile Mex-code (linked to lots of other libs), but I have to call the mingw-gcc with a windows-compatible runtime library. The clean way is to keep a complete POSIX parallel world inside your windows box. That's why my X-Server is constantly running (in seamless windows mode). You feel "at home" there, don't need to deal with the strange MSVC compiler options, code and autoconf build systems are mostly compatible .... There is lots of open source software, math and signal processing libraries that run in Cygwin without modifications, but not with MSVC. wxWindows, wxPython etc. were difficult to configure, but it works. Some of the packages you will find in the alternative "cygwin ports" repository. http://sourceware.org/cygwinports/ _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
