我使用以下cmake选项构建opencv：
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" ..
但是，当我尝试构建（使用icpc）使用opencv（使用icpc构建）的应用程序时，会出现以下警告消息：
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

这意味着什么？代码是正确的，但我想知道我是否应该为此烦恼（特别是如果这会使代码变慢，我会谈论它here）
答案 0 :(得分：1)
在英特尔编译器中使用-ipo（inter procedural optimizations）标志时，这似乎是一个问题。这是一个已知的issue。当您使用的库也使用其他库构建时，问题就会出现。但是，在构建应用程序时，我们没有明确列出这些其他库。事实上你没有必要。但是，程序间分析无法找出这些其他库，因此分析失败导致不会产生与-ipo相关的任何优化。因此，可能/可实现的性能降低。
解决方法是使用-l列出应用程序编译命令中使用的所有库（可传递）。
例如，假设我的应用程序需要库A（liba），而liba使用库B（libb）和C（libc）进行编译。 / p>
通常在我们的应用程序的链接时，我们在命令中指定-lliba。但是使用 - ipo编译器选项这还不够。您还必须在编译命令中指定-llibb -llibc。
查找库：
您可以从make文件或警告消息开始
即您的警告消息列在libs之后：libopencv_core.so, libopencv_xfeatures2d.so, libopencv_highgui.so和libopencv_imgcodecs.so
然后为每个lib运行ldd libname
这将为您提供libname库引用的库列表。您必须为找到的所有库递归运行此命令。您可以跳过系统库，例如“libc.so，linux-vdso.so”等...
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)
这里，libpfm.so很有意思。其余的lib是系统库。然后我们在libpfm.so上运行ldd
ldd libpfm.so
linux-vdso.so.1 (0x00007ffc5df9d000)
libc.so.6 => /lib64/libc.so.6 (0x00007faf97e74000)
/lib64/ld-linux-x86-64.so.2 (0x0000561984fdb000)
这只涉及系统库，因此我们可以在这里停止算法。
最后这里是libs列表：papi和pfm。
