Windows cross-compiler feature for F-11, and reddit thread
by Richard W.M. Jones 09 Nov '08

09 Nov '08

I added this a while back. It needs a bit more work: https://fedoraproject.org/wiki/Features/Windows_cross_compiler By coincidence, reddit just picked the story up. The thread is here: http://www.reddit.com/r/programming/comments/7cbjv/windows_cross_compiler_p… Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine.

I thought this list was 'a bit quiet'. Turns out that although I am an administrator of the list, I hadn't been subscribed to the list ...

Re: std library - poco compilation problem mingw - fedora10

In response to: http://lists.fedoraproject.org/pipermail/fedora-mingw/2008-November/000010.… > b) poco is already prepared for cross-compilation to mingw (under > cygwin) MinGW and Cygwin are wholly separate and different things. Do not confuse them. MinGW is just a compiler and some Win32 header files. Cross- compilation using MinGW (which is what the Fedora MinGW project is all about) uses Win32 API calls, and so Unix programs require significant porting efforts to work. eg. If your Unix program calls 'fork(2)', then forget it - it's never going to work under Win32 API until that dependency is removed or replaced. Cygwin is, essentially, a Unix emulator for Windows. Unix programs can usually be compiled directly for Cygwin with no changes, because Cygwin offers the familiar Unix/POSIX API to programs (by emulating it at great cost, including features like 'fork' which are not found on Windows and expensive to emulate). Cygwin has fatal licensing problems which prevent commercial use, apart from being inefficient, which is why we didn't go that route. So back to your program ... > i686-pc-mingw32-g++ -Iinclude > -I/home/andrzej/poco/poco-1.3.3p1/CppUnit/include > -I/home/andrzej/poco/poco-1.3.3p1/Foundation/include > -I/home/andrzej/poco/poco-1.3.3p1/XML/include > -I/home/andrzej/poco/poco-1.3.3p1/Util/include > -I/home/andrzej/poco/poco-1.3.3p1/Net/include -DPOCO_BUILD_HOST=linx > -v -mno-cygwin -D_WIN32 -DMINGW32 -DWINVER=0x500 > -DPOCO_NO_FPENVIRONMENT -DPCRE_STATIC -DPOCO_THREAD_STACK_SIZE > -DFoundation_Config_INCLUDED -I/usr/local/include -I/usr/include ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This is your problem - the cross-compilers that we ship are configured so they never look in /usr/include or /usr/local/include. Header files in /usr/include are for the build system (Fedora), and are wrong for the host system (Windows). If you specifically add /usr/include and /usr/local/include back in, then you'll pick up the wrong headers, and anything can go wrong from there. I gather that you didn't write Poco's build system, but you need to go back and find out why it's including this. Probably (as demonstrated by the MinGW / Cygwin confusion above), Poco either hasn't been ported to MinGW, or needs some different options to compile under a true MinGW cross-compiler. If that doesn't help, try reading my porting notes: http://camltastic.blogspot.com/2008/10/mingw-compile-software-for-windows.h… (or maybe I'd better say, read them again, because I see you put a comment there already).

std library - poco compilation problem mingw - fedora10

It is a great idea to add mingw packages to such major distribution. I have tried today with Fedora10 (installed fine via yum) I chose to try it on poco (http://pocoproject.org/) because: a) I urgently need it b) poco is already prepared for cross-compilation to mingw (under cygwin) It started well but is seems that the include directories are incorrect?

gtk2 on epel won't be easy
by Farkas Levente 01 Nov '08

01 Nov '08

hi, i try to build gtk2 (and it's requirements) for epel, but there is a big problem that many packages require automake-1.10 which is on fedora but not on rhel-5:-( so for the moment i give it up this part of the packages. -- Levente "Si vis pacem para bellum!"

mingw32-gettext not compile for epel-5
by Farkas Levente 31 Oct '08

31 Oct '08

hi, as requested i response here to https://bugzilla.redhat.com/show_bug.cgi?id=467398 i'm not really understand you comment. since the gnulib is part of the gettext tarball so the same gnulib compile on both case, then how can it effect the compilation? since it's compile on f-9 then why not on rhel-5? what's more that's the latest gettext source. on the other hand there is no such tool as gnulib-tool in it anywhere:-( -- Levente "Si vis pacem para bellum!"
