Intel Compiler: предупреждение # 11021: unresoved Реферировано в

Question

я построил opencv со следующими параметрами CMake:

cmake -G "Eclipse CDT4 - Unix Makefiles" -D CMAKE_BUILD_TYPE=RelWithDebInfo -DWITH_TBB=OFF -DWITH_OPENMP=ON -DCMAKE_C_COMPILER=icc -DCMAKE_CXX_COMPILER=icpc -DCMAKE_CXX_FLAGS="-debug inline-debug-info -parallel-source-info=2 -ipo -parallel -xCORE-AVX2 -Bdynamic" .. 

Однако, когда я пытаюсь построить (с icpc) приложение, которое использует OpenCV (построенный с icpc) появятся следующие предупреждающие сообщения:

icpc -shared-intel -L/home/luca/ParallelOpenCV/originalOpenCV/lib -parallel -o "SURFAllInOne" ./main.o ./surf.o -lopencv_core -lopencv_xfeatures2d -lopencv_highgui -lopencv_imgproc -lopencv_imgcodecs

Что это значит? Код правильный, но мне интересно, не стоит ли мне об этом беспокоиться (особенно, если это делает код медленнее, я говорю об этом here)

Answer 1

Похоже, что это долгое время возникало в компиляторах Intel при использовании он с -ipo (inter procedural optimizations) флаг. Это известный issue. Проблема возникает, когда библиотеки, которые вы используете, также строятся с другими библиотеками. Но мы не перечисляем эти другие библиотеки при создании нашего приложения. На самом деле вам это не нужно. Но в межпроцедурном анализе не удается найти эти другие библиотеки, и поэтому анализ завершился неудачей, что не вызвало никаких оптимизаций, связанных с -ipo. Таким образом, ухудшение в возможной/достижимой производительности.

Обходной путь заключается в перечислении всех используемых библиотек (транзитивно) в команде компиляции приложения с использованием -l.

Например, предположим, что мое приложение нуждается в библиотеку A (liba) и liba был скомпилирован с библиотеками В (libb) и C (libc).

Обычно при ссылке на наше приложение мы указываем -lliba в нашей команде. Но с - ipo вариант компилятора этого недостаточно. Вы также должны указать -llibb -llibc в своей команде компиляции.

Найти библиотеки: Вы можете начать либо из файла макияжа или предупреждающего сообщения т.е. вашего предупреждающего сообщения, перечисленное ниже LIBS: libopencv_core.so, libopencv_xfeatures2d.so, libopencv_highgui.so и libopencv_imgcodecs.so

Тогда для каждого Lib перспективы ldd libname Это даст вы список библиотек, переданных библиотекой libname. Вы должны рекурсивно запустить эту команду для всех найденных вами библиотек. Вы можете пропустить системные LIBS, такие как "libc.so, linux-vdso.so" и т.д ...

, например, когда я пытаюсь LDD на Papi библиотеке

ldd libpapi.so 
    linux-vdso.so.1 (0x00007ffe7a799000) 
    libpfm.so.4 => path to lib/libpfm.so.4 (0x00007fa2fd1c3000) 
    libc.so.6 => /lib64/libc.so.6 (0x00007fa2fcd98000) 
    /lib64/ld-linux-x86-64.so.2 (0x000056413361c000) 

Здесь libpfm.so является интересный. Остальные библиотеки - это системные библиотеки. Затем мы запускаем ldd на libpfm.so

ldd libpfm.so 
    linux-vdso.so.1 (0x00007ffc5df9d000) 
    libc.so.6 => /lib64/libc.so.6 (0x00007faf97e74000) 
    /lib64/ld-linux-x86-64.so.2 (0x0000561984fdb000) 

Это относится только к системе LIBS, поэтому мы можем остановить наш алгоритм здесь.

В конце приведен список библиотек: papi и pfm.
