For this we need to know which bugs are still valid and which could be closed already. Thus we are setting the bug state to "Incomplete" now. If the bug has already been fixed in the latest upstream version of QEMU, then please close this ticket as "Fix released". If it is not fixed yet and you think that this bug report here is still valid, then you have two options: 1) If you already have an account on gitlab.com, please open a new ticket for this problem in our new tracker here: https://gitlab.com/qemu-project/qemu/-/issues and then close this ticket here on Launchpad (or let it expire auto- matically after 60 days). Please mention the URL of this bug ticket on Launchpad in the new ticket on GitLab. 2) If you don't have an account on gitlab.com and don't intend to get one, but still would like to keep this ticket opened, then please switch the state back to "New" within the next 60 days (otherwise it will get closed as "Expired"). We will then eventually migrate the ticket auto- matically to the new system (but you won't be the reporter of the bug in the new system and thus won't get notified on changes anymore). Thank you and sorry for the inconvenience. ** Changed in: qemu Status: New =3D> Incomplete -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1885827 Title: building plugin failed on Windows with mingw Status in QEMU: Incomplete Bug description: I want to build QEMU 4.2.0's plugin module on Windows 7/10 with Mingw, bu= t the building process faild. = The step I follow is listed below: 1. create "dsp_build" diretory under source file folder 2. change directory to dsp_build , and run ../configure --target-list=3D= dsp-softmmu --cross-prefix=3Dx86_64-w64-mingw32- --enable-gtk --enable-sdl = --enable-debug --enable-plugins 3. build qemu project 4. switch dir to /dsp_build, make -C tests/plugin, yeilds error: = CC bb.o D:/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/tests/plugin/bb.c:17:2= 4: error: variable 'qemu_plugin_version' definition is marked dllimport 17 | QEMU_PLUGIN_EXPORT int qemu_plugin_version =3D QEMU_PLUGIN_VERSIO= N; | ^~~~~~~~~~~~~~~~~~~ D:/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/tests/plugin/bb.c:17:2= 4: warning: 'qemu_plugin_version' redeclared without dllimport attribute: p= revious dllimport ignored [-Wattributes] D:/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/tests/plugin/bb.c: In = function 'vcpu_tb_exec': D:/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/tests/plugin/bb.c:33:2= 9: warning: cast from pointer to integer of different size [-Wpointer-to-in= t-cast] 33 | unsigned long n_insns =3D (unsigned long)udata; | ^ D:/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/tests/plugin/bb.c: In = function 'vcpu_tb_trans': D:/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/tests/plugin/bb.c:51:4= 6: warning: cast to pointer from integer of different size [-Wint-to-pointe= r-cast] 51 | (void *)n_insns); 5.
