I've been trying to install CUDA and cuDNN for TensorFlow as instructed on the TensorFlow page. Everything works until I do the following:
$ cp -r /usr/local/cuda/samples ~/cuda-samples
$ pushd ~/cuda-samples
$ make
I then get the following error:
clang++ -rpath /Developer/NVIDIA/CUDA-7.5/lib -L/Developer/NVIDIA/CUDA-7.5/lib -framework CUDA -o clock_nvrtc clock.o -lnvrtc
ld: framework not found CUDA
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [clock_nvrtc] Error 1
make: *** [0_Simple/clock_nvrtc/Makefile.ph_build] Error 2
My question of course is what's causing the error, and how to fix it. I had previously installed CUDA 7.5, and then I installed 8.0. The whole of CUDA (and its installation) is just a black box to me; I'm just trying to get it to work with TensorFlow.
Thanks!
Add the folder containing the folder CUDA.framework to the command line as such:
-F<folder>
It looks like the linker isn't able to find the framework and you have to point it where it is
Run the following in your terminal -
xcode-select --install
Then try to run make again.
Saw the answer on an NVidia forum - https://devtalk.nvidia.com/default/topic/628298/cuda-samples-on-mac-os-x-mavericks-10-9-matrixmuldrv/
It's also documented in this Quick Start Guide - http://docs.nvidia.com/cuda/cuda-quick-start-guide/index.html#axzz4YvZYOZc0

I am trying to compile the linux kernel for riscv64 using the following link -
https://risc-v-getting-started-guide.readthedocs.io/en/latest/linux-qemu.html
While building linux with the command make ARCH=riscv CROSS_COMPILE=riscv64-unknown-linux-gnu- defconfig
the following error shows up -
scripts/kconfig.include:35 compiler riscv64-unknown-linux-gnu-gcc not found in PATH
scripts/kconfig/Makefile:82:recipe for target 'defconfig' failed
I have included path of tool chain. Still not working. Attached the screenshot of folder structure and error.
I would suggest to provide the full prefix for your toolchain in the make command, for example:
wget https://toolchains.bootlin.com/downloads/releases/toolchains/riscv64/tarballs/riscv64--glibc--bleeding-edge-2020.02-2.tar.bz2
mkdir -p /opt/bootlin
tar jxf riscv64--glibc--bleeding-edge-2020.02-2.tar.bz2 -C /opt/bootlin
make ARCH=riscv CROSS_COMPILE=/opt/bootlin/riscv64--glibc--bleeding-edge-2020.02-2/bin/riscv64-buildroot-linux-gnu- mrproper defconfig Image
Compilation should complete without errors - using linux 5.7.11 here:
HOSTCC scripts/basic/fixdep
HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/confdata.o
HOSTCC scripts/kconfig/expr.o

It is saying compiler riscv64-unknown-linux-gnu not found which means either riscv gnu toolchain is not installed on your machine or it is not found by the shell instance in which you are trying to compile linux kernel.
To check if RISC-V GNU toolchain is installed, create a simple C file and try to compile it with RISC-V gnu toolchain with following command:
riscv64-unknown-linux-gnu-gcc <filename.c> -o <binaryname>
1. If RISC-V GNU Toolchain is not installed:
Follow the instruction here to install riscv gnu toolchain. And keep in mind to compile it with make linux instead of make.
2. If RISC-V GNU Toolchain is installed or you are done installing
Add it to the $PATH variable inside .bashrc file located on home directory.
Then try compiling your kernel again.
When I was compiling Caffe, I had this error, despite OpenBLAS is installed:
AR -o .build_release/lib/libcaffe.a
LD -o .build_release/lib/libcaffe.so
/usr/bin/ld: cannot find -lopenblas
collect2: ld devolvió el estado de salida 1
make: *** [.build_release/lib/libcaffe.so] Error 1
Is there a solution for it?
Including the base packs even after cloning OpenBlas and making will link the appropriate libraries in 14.04 and 16.
apt install liblapack-dev liblapack3 libopenblas-base libopenblas-dev
apt install liblapack-dev liblapack3 libopenblas-base libopenblas-dev
I faced the same problem. Even adding library directory "/opt/OpenBLAS/lib/" to ldconfig cache didn't help (as my libopenblas.so is at "/opt/OpenBLAS/lib/libopenblas.so").
Using cmake helped me. Try this from caffe root directory:
mkdir build
cd build
cmake -DBLAS=open ..
make all
make runtest
If you need to use make, add the symlink of libopenblas.so to /usr/lib. I did the following:
ln -s /opt/OpenBLAS/lib/libopenblas.so /usr/lib/libopenblas.so
I saw the similar problem (I'm compiling caffe again for some reason).
I found the library file the builder is looking for (-lcblas or -latlas means libcblas.so and libatlas.so) are under /usr/lib64/atlas. So just added symbolic links under /usr/lib64 like this.
sudo ln /usr/lib64/atlas/libcblas.so.3.0 /usr/lib64/libcblas.so
sudo ln -s /usr/lib64/atlas/libatlas.so.3.0 /usr/lib64/libatlas.so
But I guess more proper method is to set Makefile.config (the CBLAS path). (I thought the default path will do away with it reading the comment saying so, but it did not.) Hope this helps anyone.
I have installed SimpleCV 1.3 powerpack in my Windows 8.1. Then i set up the required path. And then i installed pyreadline, PIL, pip, ipython via cmd. But when i tried to run easy_install cython, i'm getting the following error,

I'm using a double partition system Windows8/Xubuntu14.04LTS.
I had the same issue when attempting to install Cython onto Xubuntu via pip.
So I installed Cython with below command and and everything went ok.
bashsh $ sudo apt-get install cython
This is not the best fix. But, may worth a trial if you are really
looking to port an almost complete project to Windows8.
You compile your Python main (without main):
bash $ cython --embed -o prog.c prog.py
You may decide to install Mxe (MingW) gcc on linux and do
cross compiling or, as me, to compile directly in the windows8:
bash $ gcc -Os -IC:\Python27\include -LC:\Python27\libs -o prog.exe prog.c -lpython27 -DMS_WIN64
Hope this might be of any help.
I installed the driver and toolkit for CUDA 5 in 64-bit RHEL 6.3 successfully.
However, when I tried compiling the CUDA 5 examples, I got the error message:
make[1]: Leaving directory `/root/NVIDIA_CUDA-5.0_Samples/0_Simple/cppIntegration'
which: no mpicxx
How can I fix this for the CUDA 5 examples to compile?
In order to build the simpleMPI example, you need some kind of MPI installed on your system. You can get around this and build most of the samples by doing:
make -k
this will attempt to go past errors in the make process and build all targets that can be built.
If you prefer, you can delete this directory:
/root/NVIDIA_CUDA-5.0_Samples/0_Simple/simpleMPI
perhaps with the following command, as root:
rm -Rf /root/NVIDIA_CUDA-5.0_Samples/0_Simple/simpleMPI
and relaunch your make. Personally I think the make -k option is simpler.
(the message about cppIntegration is just the last target that got successfully built)
i've a Problem with MySQL C API and Mac OS X 10.6. When i want to compile a SQL Client Program, it aborts with this Error Message
ld: library not found for -lmysqlclient
collect2: ld returned 1 exit status
I compile with this command:
g++ -I /usr/local/mysql/include/ -L /usr/local/mysql/lib/ -lmysqlclient main.cpp
I've tried the Headers and Librarys in different locations - no effect
I've downloaded the headers and the Library from an other Destination - Same effect as before
Any Ideas what i am doing wrong?
If there is a thread allready i want to excuse (nothing found in search)!
Greeting, Dennis
So after many days, of not intensive work ;-) here's the fault:
the compiler doesn't accept the library if it is in the standard install directory. I copied the include and lib files into /usr/local/include and /usr/local/lib . Now it compiles without errors :-)
I don't know why it only works in the standard paths but however now it works.
