  It seems that it was unable to find openjpeg.h and searched in folder openjpeg-2.0 to openjpeg-2.3. However, when I checked /mxe/usr/i686-w64-mingw32.static/include/, it contains openjpeg-2.4.

  


  The log for /mxe/log/gdal_i686-w64-mingw32.static is present here.

  


  Please help fix this. Thanks.

  


• Compliing OpenCV with FFMPEG failing

  20 mai 2016, par moorej

  I’m trying to install OpenCV 3.1.0 on Ubuntu 14.04 with ffmpeg and python 2.7 support. I’m able to compile with :

  cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local 
  
  -D  INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=ON 
  
  -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.1.0/modules 
  
  -D WITH_FFMPEG=OFF -D BUILD_EXAMPLES=ON ..

  But -D WITH_FFMPEG=ON fails with the error :

  /usr/bin/ld: /usr/local/lib/libavcodec.a(avpacket.o): 
  
  relocation R_X86_64_32 against `.rodata.str1.1' can not be used when
  
  making a shared object; recompile with -fPIC
  
  /usr/local/lib/libavcodec.a: error adding symbols: Bad value
  
  collect2: error: ld returned 1 exit status

  I’m compiling ffmpeg as well and I’ve looked at a number of posts relating to the problem and attempted to add —enable-pic and —enable-shared along with some other options but I have to admit I’m a bit stupid when it comes to anything compilation related. My process for compiling ffmpeg is below. Please help me with my mess. Thanks !
