I compiled caffe successfully at first and tried the MNIST example. But there is something wrong when I tried to install pycaffe. So I reinstalled caffe. However I received compiling error this time.

I figured out it was the problem between two version of python. The system default version and the anaconda one. You have to make sure the compiling and executing using the same one.
I want to install either oursql or MySQLdb on a Cygwin box. (Pywikibot can work with either.)
Unfortunately both easy_install as well as pip fail at installing both.

I haven't done much gcc fixing in the past decade so I'm not sure how to handle this.

I'm trying to install CUDA 7.0 on Ubuntu 14.04. I've followed the installation instructions as outlined here. Specifically, I've followed steps in section 3.6 and Chapter 6. While compiling the examples (Section 6.2.2.2) using make, I'm getting the following error:
make[1]: Entering directory `/usr/local/cuda-7.0/samples/3_Imaging/cudaDecodeGL'
/usr/local/cuda-7.0/bin/nvcc -ccbin g++ -m64 -gencode arch=compute_20,

/usr/bin/ld: cannot find -lnvcuvid
collect2: error: ld returned 1 exit status
make[1]: *** [cudaDecodeGL] Error 1
make[1]: Leaving directory `/usr/local/cuda-7.0/samples/3_Imaging/cudaDecodeGL'
make: *** [3_Imaging/cudaDecodeGL/Makefile.ph_build] Error 2
If you notice, there is -L/usr/lib/"nvidia-346". In my case, I have installed nvidia-349. What worked for me is to edit NVIDIA_CUDA-7.0_Samples/3_Imaging/cudaDecodeGL/findgllib.mk and change UBUNTU_PKG_NAME = "nvidia-346" to nvidia-349.
In order to properly install CUDA 7.0 on Ubuntu 14.04, you need a nvidia driver version 346 or higher.
If you're using the .deb installation method, the nvidia graphics driver is installed automatically.
If you used the .run file installation method and chose not to install the nvidia driver, you can manually install the driver afterwards through the package manager:
sudo apt-add-repository ppa:xorg-edgers/ppa && sudo apt-get update
sudo apt-get install nvidia-346 nvidia-346-dev nvidia-346-uvm libcuda1-346 nvidia-libopencl1-346 nvidia-icd-346
In my case, I installed nvidia-352 afterwards due to a bug in nvidia-346 and I stumbled upon the same error.
andoum's approach of manually changing the hard-coded UBUNTU_PKG_NAME = "nvidia-346" to UBUNTU_PKG_NAME = "nvidia-352" in NVIDIA_CUDA-7.0_Samples/3_Imaging/cudaDecodeGL/findgllib.mk worked fine for me.
I met the same issue and solution is that put path of nvidia into system path:
sudo gedit /etc/environment
add these path into environment
LIBRARY_PATH=/usr/lib/your_nvidia_edition:$LIBRARY_PATH
In fact I have encountered this problem when I made a make. I installed Cuda 8.0 under my Ubuntu 16.04. This problem had been confusing me for several weeks and I was almost tending to reinstall ubuntu for that after reviewing many suggestions via google, but finally I addressed it myself recently.
First of all, you should replace all the UBUNTU_PKG_NAME= ##nvidia-3xx## to the one of your actually installed nvidia driver version as recommended above. Then you will probably get compiling error after you do a new make. In my case, I have the link errors like
/usr/bin/ld: warning: libGLX.so.0, needed by /usr/lib/nvidia-
375/libGL.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libGLdispatch.so.0, needed by /usr/lib/nvidia-
375/libGL.so, not found (try using -rpath or -rpath-link)
....
or whatever contains missing link errors. Do locate the files you miss like
$ locate libGLX.so.
/usr/lib/nvidia-375/libGLX.so.0
/usr/lib32/nvidia-375/libGLX.so.0
$ locate libGLdispatch.so.0
/usr/lib/nvidia-375/libGLdispatch.so.0
/usr/lib32/nvidia-375/libGLdispatch.so.0
The error above is probably caused the compiling files cannot find in the default cuda libraries as you set, so you just need to copy the missing files to /usr/lib/nvidia-3xx/ (the actual path in your case) and this should work(it works in my case), if it doesn't maybe you could try to link the new add files to the one that need using a
$ sudo ln -s (requested file) (requesting file).
Hope this will help.
I have followed all steps mentioned in Compiling the SDK for HTML5 to compile the Minko framework to HTML5.
When I run the batch file build_html5.bat, i have this error

Im on windows 7 64 bit.
Anyone know what causes this error and how can I resolve it?
This is a known problem with Emscripten 1.30, it should be resolved in future versions. For the moment, stick to Emscripten 1.29.

Any ideas? The desktop configuration is working. The JDK is 1.7+
I have installed the latest gradle setup for libgdx
Thanks
See for solution here: https://github.com/robovm/robovm/issues/238
You need to remove zero-length class from cache and run build again.
