مشکل در کامپایل opencv برای استفاده در کیوت

[gholami.vahid]

سلام دوستان
من آموزش های کامپایل کردن فایل های سورس opencv رو از وب سایت های مختلف تست کردم و نتونستم اون رو با کامپایلر mingw برای کیوت آماده کنم . از دوستانی که اطلاعات در زمینه آموزش برنامه نویسی opencv بر روی کیوت دارن ممنون میشم راهنماییم کنید .
من با استفاده از این آموزش http://opencv.ir/forum/viewtopic.php?f=66&t=268 پیش رفتم و زمان generate در cmake با خطا هایی زیر روبرو میشوم

CMake Warning (dev) in apps/traincascade/CMakeLists.txt:
Policy CMP0020 is not set: Automatically link Qt executables to qtmain
target on Windows. Run "cmake --help-policy CMP0020" for policy details.
Use the cmake_policy command to set the policy and suppress this warning.
This warning is for project developers. Use -Wno-dev to suppress it.

اینها خطا نیستند، اخطار هستند. با وجود اخطار ها کامپایل باید صورت گیرد.

[gholami.vahid]

آره میدونم اخطار هستند اما نمیدونم وقتی دستور زیر رو اجرا میکنم تا ۵۰ فقط میره .
E:\Qt.5.2.0\opencv\build>mingw32-make –j16
ممنون میشم اگه کمکم کنید اخه خیلی لازمش دارم .

[حامد مصافی]

کل متن خروجی رو ضمیمه کنید

سلام پیوست شد

[حامد مصافی]

من که خطایی ندادم در این خروجی، آخر لاگ هم که پیغام موفقیت هست. ظاهرا همه چیز باید درست باشه.

اره اما حالا باید cmd رو باز کنیم و به ادرس پوشه

build بریم و کد زیر رو بزنیم

mingw32-make –j16

این دستور تا 50 بعضی وقتا تا 60 میره و بیشتر از این نمیره تصویر پیوست رو نگاه کنید

[حامد مصافی]

این خروجی کامپایل رو هم به صورت کامل بذارید اینجا تا ببینیم

[gholami.vahid]

این خروجی کامپایل رو هم به صورت کامل بذارید اینجا تا ببینیم

منظور این پوشه بود ؟

[حامد مصافی]

نه دوست عزیز، منظورم تمامی چیزهاییه که در Command Prompt نمایش داده میشه. در همین پوشه هم محتویات bin رو چک کن

ظاهرا مشکل قبلی حل شده و مشکل جدیدی نمایان شده، اینجا در مورد مشکل جدید توضیح داده، ظاهرا کاربران زیادی این هشدار رو دریافت کردند.
طبق راهنمایی‌های همین لینک در فایل OpenCVCompilerOptions.cmake به دنبال خطی مانند زیر بگردید و پس از یافتن به ابتدای آن یک # اضافه کنید.

add_extra_compiler_option(-Werror=non-virtual-dtor)

[gholami.vahid]

جواب نداد . نمیشه یه کیوت دیگه بگیرم که نیاز به کامپایلر مینگ نباشه . من میخوام سی پلاس کد بزنم و نیاز به یه فرم خوشکل واسه برنامه پردازش تصویرم دارم . واسه همین میخوام از کیوت استفاده کنم . نمیشه فایلهای opencv که برای ویژال استدیو گرفتم رو استفاده کنم . حتما باید این opencv زو با مینگ کامپایل کنم . در ضمن سرعت پردازش تصویر برام مهمه . میشه تو این زمینه راهنماییم کنید .

من الان دارم از opencv رو ویژوال 2012 استفاده میکنم و این ceemple در مورد کیوت چیزی نداشت یا من ندیدم .

سلام
شما اول این فایل دانلود کنید
http://sourceforge.net/projects/open...0.exe/download
به عنوان مثال شما در درایو E نصب کردین
بعد کیوت را باز کنید و یک پروژه ایجاد کنید
واین دستورات را در فایل .pro اضافه کنید


INCLUDEPATH+=E:/opencv/opencv/build/include

LIBS+=-LE:/opencv/opencv/build/x86/vc11/lib -lopencv_ts300 -lopencv_world300


بعد dll های پوشه E:\opencv\opencv\build\x86\vc11\bin در کنار برنامه خودتون کپی کنید.

در ضمن این چیزی که گفتم برای کامپایلر Microsoft Visual Studio 2012 برای Qt هست.
