Debian使用IPP编译OpenCV示例：/ usr / bin / ld：找不到-llibsvml.so collect2：error：ld返回1退出状态

环境：Debian 7.5 Wheezy。

我刚刚编译并安装了版本为2.4.9的OpenCV库，并激活了英特尔IPP（集成性能基元）。 我在/ opt / ipp版本8.1 SP 3中安装了IPP。

在cmake期间，它findOK IPP库，并编译并安装在/ opt / OpenCV中，没有任何问题。

当我进入c例子文件夹时，有一个编译所有例子的脚本：

• 包含和/或链接你的二进制没有使用的东西的负面后果是什么？
• 从Code :: Blocksconfigurationg ++不会影响命令行
• C ++：g ++编译器：与虚拟function的stdio的冲突？
• 有没有办法find在Linux上编译.so库时使用的编译器选项？
• 为什么boost :: timer这样奇怪的结果？

现在，让我们运行脚本：

 $ ./build_all.sh 

每个源文件都提供如下的输出：

 compiling tree_engine.cpp /usr/bin/ld: cannot find -llibsvml.so /usr/bin/ld: cannot find -llibimf.so /usr/bin/ld: cannot find -llibirc.so /usr/bin/ld: cannot find -llibippcore.a /usr/bin/ld: cannot find -llibipps.a /usr/bin/ld: cannot find -llibippi.a /usr/bin/ld: cannot find -llibippcv.a /usr/bin/ld: cannot find -llibippcc.a /usr/bin/ld: cannot find -llibippvm.a collect2: error: ld returned 1 

build_all.sh的内容：

 #!/bin/sh if [ $# -gt 0 ] ; then base=`basename $1 .c` echo "compiling $base" gcc -ggdb `pkg-config opencv --cflags --libs` $base.c -o $base else for i in *.c; do echo "compiling $i" gcc -ggdb `pkg-config --cflags opencv` -o `basename $i .c` $i `pkg-config --libs opencv`; done for i in *.cpp; do echo "compiling $i" g++ -ggdb `pkg-config --cflags opencv` -o `basename $i .cpp` $i `pkg-config --libs opencv`; done fi 

我们先关注第一个找不到的库（/ usr / bin / ld：找不到-llibsvml.so）。

它在系统中：$ locate libsvml.so /opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/ia32/libsvml.so /opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/intel64/libsvml.so / opt / intel /composer_xe_2013_sp1.3.174/compiler/lib/mic/libsvml.so

它的文件夹在LD_LIBRARY_PATH中：

 $ echo $LD_LIBRARY_PATH /opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/intel64:/opt/intel/composer_xe_2013_sp1.3.174/mpirt/lib/intel64:/opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/intel64:/opt/intel/composer_xe_2013_sp1.3.174/ipp/lib/intel64:/opt/OpenCV/OpenCV-2.4.9/lib 

在LIBRARY_PATH中：

 $ echo $LIBRARY_PATH /opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/intel64:/opt/intel/composer_xe_2013_sp1.3.174/ipp/lib/intel64 

据我所见，buildAll脚本依靠pkg-config来查找库。 值得注意的是这些命令在运行时不会返回任何内容

 $ pkg-config --list-all | grep ipp $ pkg-config --list-all | grep vml $ dpkg -l | grep ipp $ dpkg -l | grep vml 

编译期间gcc在哪里寻找：

 $ gcc --print-search-dirs install: /usr/lib/gcc/x86_64-linux-gnu/4.7/ programs: =/usr/lib/gcc/x86_64-linux-gnu/4.7/:/usr/lib/gcc/x86_64-linux-gnu/4.7/:/usr/lib/gcc/x86_64-linux-gnu/:/usr/lib/gcc/x86_64-linux-gnu/4.7/:/usr/lib/gcc/x86_64-linux-gnu/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../x86_64-linux-gnu/bin/x86_64-linux-gnu/4.7/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../x86_64-linux-gnu/bin/x86_64-linux-gnu/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../x86_64-linux-gnu/bin/ libraries: =/opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/intel64/x86_64-linux-gnu/4.7/:/opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/intel64/x86_64-linux-gnu/:/opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/intel64/../lib/:/opt/intel/composer_xe_2013_sp1.3.174/ipp/lib/intel64/x86_64-linux-gnu/4.7/:/opt/intel/composer_xe_2013_sp1.3.174/ipp/lib/intel64/x86_64-linux-gnu/:/opt/intel/composer_xe_2013_sp1.3.174/ipp/lib/intel64/../lib/:/usr/lib/gcc/x86_64-linux-gnu/4.7/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../x86_64-linux-gnu/lib/x86_64-linux-gnu/4.7/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../x86_64-linux-gnu/lib/x86_64-linux-gnu/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../x86_64-linux-gnu/lib/../lib/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../x86_64-linux-gnu/4.7/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../x86_64-linux-gnu/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../lib/:/lib/x86_64-linux-gnu/4.7/:/lib/x86_64-linux-gnu/:/lib/../lib/:/usr/lib/x86_64-linux-gnu/4.7/:/usr/lib/x86_64-linux-gnu/:/usr/lib/../lib/:/opt/intel/composer_xe_2013_sp1.3.174/compiler/lib/intel64/:/opt/intel/composer_xe_2013_sp1.3.174/ipp/lib/intel64/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../x86_64-linux-gnu/lib/:/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../:/lib/:/usr/lib/ 

我怎样才能编译这个，所以海湾合作委员会发现IPP库？

编辑1

我已经尝试创build一个文件/etc/ld.so.conf.d/IntelIPP.conf并在那里添加设置在LD_LIBRARY_PATH中的英特尔IPPpath，重新启动系统并重新编译。 没有效果。

但是，我猜这是： “/ usr / bin / ld：找不到-llibsvml.so”应该表示它正在寻找一个“liblibsvml.so”（ld在库文件名内部足够“lib”认为）。

还有一点要注意： “gcc -ggdb pkg-config --cflags opencv -o basename $i .c $ i`pkg-config –libs”只针对opencv执行pkg-config，没有任何IPP被命名。 所以，在编译或者安装的时候，这可能是OpenCV硬编码的一些lib位置。

有关这个的任何线索？

按照这个新的方法，我去了〜/ Downloads / openscv-2.4.9 / cmake / OpenCVFindIPP.cmake并且改变了：

 # ------------------------------------------------------------------------ # This is auxiliary function called from set_ipp_variables() # to set IPP_LIBRARIES variable in IPP 7.x and 8.x style # ------------------------------------------------------------------------ function(set_ipp_new_libraries _LATEST_VERSION) set(IPP_PREFIX "ipp") if(${_LATEST_VERSION} VERSION_LESS "8.0") set(IPP_SUFFIX "_l") # static not threaded libs suffix IPP 7.x else() if(WIN32) set(IPP_SUFFIX "mt") # static not threaded libs suffix IPP 8.x for Windows else() set(IPP_SUFFIX "") # static not threaded libs suffix IPP 8.x for Linux/OS X endif() endif() set(IPPCORE "core") # core functionality set(IPPSP "s") # signal processing set(IPPIP "i") # image processing set(IPPCC "cc") # color conversion set(IPPCV "cv") # computer vision set(IPPVM "vm") # vector math set(IPP_LIBRARIES ${IPP_PREFIX}${IPPVM}${IPP_SUFFIX}${IPP_LIB_SUFFIX} ${IPP_PREFIX}${IPPCC}${IPP_SUFFIX}${IPP_LIB_SUFFIX} ${IPP_PREFIX}${IPPCV}${IPP_SUFFIX}${IPP_LIB_SUFFIX} ${IPP_PREFIX}${IPPI}${IPP_SUFFIX}${IPP_LIB_SUFFIX} ${IPP_PREFIX}${IPPS}${IPP_SUFFIX}${IPP_LIB_SUFFIX} ${IPP_PREFIX}${IPPCORE}${IPP_SUFFIX}${IPP_LIB_SUFFIX}) if (UNIX) set(IPP_LIBRARIES ${IPP_LIBRARIES} irc${CMAKE_SHARED_LIBRARY_SUFFIX} imf${CMAKE_SHARED_LIBRARY_SUFFIX} svml${CMAKE_SHARED_LIBRARY_SUFFIX}) endif() set(IPP_LIBRARIES ${IPP_LIBRARIES} PARENT_SCOPE) return() endfunction() 

通过：

重新编译OpenCV，并成功安装…没有运气。 现在编译示例给出了相同的错误，但没有“lib”：

 compiling tree_engine.cpp /usr/bin/ld: cannot find -lsvml.so /usr/bin/ld: cannot find -limf.so /usr/bin/ld: cannot find -lirc.so /usr/bin/ld: cannot find -lippcore.a /usr/bin/ld: cannot find -lipps.a /usr/bin/ld: cannot find -lippi.a /usr/bin/ld: cannot find -lippcv.a /usr/bin/ld: cannot find -lippcc.a /usr/bin/ld: cannot find -lippvm.a collect2: error: ld returned 1 exit status

另一种方法：在/opt/OpenCV/OpenCV-2.4.9/中search“svml”。

这导致2个文件。

/opt/OpenCV/OpenCV-2.4.9/share/OpenCV/OpenCVModules-debug.cmake：

 # Import target "opencv_ts" for configuration "Debug" SET_PROPERTY(TARGET opencv_ts APPEND PROPERTY IMPORTED_CONFIGURATIONS DEBUG) SET_TARGET_PROPERTIES(opencv_ts PROPERTIES IMPORTED_LINK_INTERFACE_LANGUAGES_DEBUG "CXX" IMPORTED_LINK_INTERFACE_LIBRARIES_DEBUG "opencv_core;opencv_flann;opencv_imgproc;opencv_highgui;opencv_features2d;dl;m;pthread;rt;/usr/lib/x86_64-linux-gnu/libGLU.so;/usr/lib/x86_64-linux-gnu/libGL.so;/usr/lib/x86_64-linux-gnu/libSM.so;/usr/lib/x86_64-linux-gnu/libICE.so;/usr/lib/x86_64-linux-gnu/libX11.so;/usr/lib/x86_64-linux-gnu/libXext.so;tbb;libippvm.a;libippcc.a;libippcv.a;libippi.a;libipps.a;libippcore.a;libirc.so;libimf.so;libsvml.so" IMPORTED_LOCATION_DEBUG "${_IMPORT_PREFIX}/lib/libopencv_ts.a" ) LIST(APPEND _IMPORT_CHECK_TARGETS opencv_ts ) LIST(APPEND _IMPORT_CHECK_FILES_FOR_opencv_ts "${_IMPORT_PREFIX}/lib/libopencv_ts.a" ) 

只显示第211至220行。不知道这些行真正的意思。

/opt/OpenCV/OpenCV-2.4.9/lib/pkgconfig/opencv.pc

我认为这个文件是非常有趣的，据我所知，这是pkg-config和ld在链接和编译时加载库的文件。

注意这个：

我仍然不知道该怎么办… -l [xxx]应该从LD_LIBRARY_PATH加载xxx，所以这应该工作…任何想法？
