zzningxp commented on issue #2027: [lib/libmxnet.so] Error installing mxnet for EI Capitan 10.11.4 URL: https://github.com/apache/incubator-mxnet/issues/2027#issuecomment-326478495 I ran into the same issue with Macbook Pro late 2015, 10.12.3 Sierra, gcc-7. I believe that the issue is cause by two versions of OpenCV (2.4.13 and 3.2), because I ran into OpenCV issue several times on my MBP. So, I tried 2.4.13.2 and 3.20 and HEAD-3649ee3, and only 2.4.13 works, with g++/clang++, not g++-7. ``` mxnet daodao$ g++ --version Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 8.1.0 (clang-802.0.42) Target: x86_64-apple-darwin16.4.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin ``` The most important thing here is to setup OpenCV version explicitly: ``` # setup opencv ifeq ($(USE_OPENCV), 1) CFLAGS += -DMXNET_USE_OPENCV=1 -I/usr/local/Cellar/opencv/2.4.13.2/include -I/usr/local/include LDFLAGS += $(filter-out -lopencv_ts, -L/usr/local/Cellar/opencv/2.4.13.2/lib -lopencv_shape -lopencv_stitching -lopencv_objdetect -lopencv_superres -lopencv_videostab -lopencv_calib3d -lopencv_features2d -lopencv_highgui -lopencv_videoio -lopencv_imgcodecs -lopencv_video -lopencv_photo -lopencv_ml -lopencv_imgproc -lopencv_flann -lopencv_core) #CFLAGS += -DMXNET_USE_OPENCV=1 $(shell pkg-config --cflags opencv) #LDFLAGS += $(filter-out -lopencv_ts, $(shell pkg-config --libs opencv)) BIN += bin/im2rec else CFLAGS+= -DMXNET_USE_OPENCV=0 endif ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
