problem using gcc-core for compile qemu
Good morning happy new year, first of all I am going to ask you that when you read my case, do not refer me to another tool, do not refer me to another environment, but above all do not ask me to read because I already read all of Google and there is no solution , but I refuse to think that there is not, it is simply that nobody has bothered to publish it. I am using the gcc-core 9.3 package to compile qemu, I use this one because mingw does not incorporate all the features that I am looking for, and gcc is able to search for resources as it would in linux whereas mingw cannot unless the paths are edited. the problem that appears to me is the following: ERROR: Unrecognized host OS (uname -s reports 'CYGWIN_NT-10.0'), there are no options to indicate the target, there are no options to avoid the operating system test, (at least not in a simple way). How could I solve the failure? I beg that it be done as I have it configured -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
lookup problem in compiler
Hello, I am trying to compile certain programs in windows 10 and I have a curious problem, I use mingw64-x86_64-w64-mingw, when I add related packages if it is able to locate them but if I install packages that are not related it is not able to locate them, yes cygwin is supposedly compatible with posix because it doesn't localize them?. For example, if I install mingw64-x86_64-gtk3, then in the console the compiler finds it perfect, but if I install libncurse-dev it is not able to locate it indicating that it is not there when it really is, this failure does not occur in Linux, as I solve this? -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

undetectable libraries
good evening, I have a strange problem, I try to compile code that uses gtk3 and sdl2 in addition to curl, the problem is that when I invoke the gcc compiler it tells me that sdl2-devel and libcurl are not installed, but actually yes are. ./configure --cross-prefix=x86_64-w64-mingw32- --enable-sdl --enable-gtk --enable-curl I'm not sure if they allow to send screenshot to show windows of the cygwin package installer so they can see the installed packages. How could I find the variable and add it to compile? -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
Re: help compilation qemu
Hi Caba, I know qemu-system-i386 because the official binary is that size.As for the command used I use this:x86_64-w64-mingw32- this way it compiles perfectly except for the file sizes, if I add the option - s the error Bash option -s unknown, I use 64-bit El dom., 24 may. 2020 11:32, Csaba Ráduly via Cygwin escribió: > > Hi Juan Carlos, > > On 24/05/2020 02:08, Juan carlos Rebate via Cygwin wrote: > ... > > > 1 the compiler is extremely slow, gcc on Linux is about 10 times > > faster, How could I speed up the compilation process?. > > Unfortunately, Cygwin's emulation of fork() is slow compared to the native > Linux > implementation (I've seen 1000x difference once, in a test launching the > same > program repeatedly).

help compilation qemu
Good morning, in a previous post I was debating with some nice users (for technical reasons I can't retrieve that thread)The point is that although the qemu wiki says it can't compile with cygwin for 64-bit it actually can, and for technical reasons I haven't been able to communicate it before,The case is that making a couple of adjustments when looking for all the mingw packages if they can be found, but there is a problem,Well, really two problems.1 the compiler is extremely slow, gcc on Linux is about 10 times faster, How could I speed up the compilation process?. 2 the executables produced are too fat, for example qemu-system-i386 is 65 MB, but it should be 10.5 MB, if I use the -s option in configure returns an unknown error message, how could I fix it?

Re: help compilation qemu
Yes, pkconfig is among the requirements although today in 2020 that package is not in cygwin, due to the scarce documentation in this regard, I will try to see if a cross-compilation is feasible.

Re: help compilation qemu
I can't use msys2 because when I use the Syu command it is not able to resolve the download url,The only missing component is mingw64-686-pkconfig, all other components if they are in cygwin El sáb., 2 may. 2020 22:24, Maarten Hoes escribió: > Hi, > > I have no personal experience with this, but when I take a look at the > QEMU wiki, it seems that : > > > [1] > Builds with cygwin are not really supported. > https://wiki.qemu.org/Hosts/W32#Native_builds_with_Cygwin > > > [2] > A supported way of building QEMU on Windows is with MSYS2 > https://wiki.qemu.org/Hosts/W32#Native_builds_with_MSYS2 > > > Hope this helps. > > > - Maarten > > > On Sat, May 2, 2020 at 9:31 PM Juan carlos Rebate via Cygwin < > cygwin@cygwin.com> wrote: > >> Hello, it is the first time that I write here, sorry for the possible >> malfunctions of the mailing list.I am interested in compiling qemu with >> cygwin and the documentation is scarce, it only indicates that the >> environment is complete but it does not indicate all the necessary >> components,The components that they mention are not available in cygwin, >> for example Mingw64-686-pkconfig is not included in the repositories, >> could >> someone give me a complete manual?

Re: help compilation qemu
I'm already aware of the availability of binaries for windows, but I want to compile it myself, I ask because qemu documentation is sparse.

Hello, it is the first time that I write here, sorry for the possible malfunctions of the mailing list.I am interested in compiling qemu with cygwin and the documentation is scarce, it only indicates that the environment is complete but it does not indicate all the necessary components,The components that they mention are not available in cygwin, for example Mingw64-686-pkconfig is not included in the repositories, could someone give me a complete manual?
