CUDA incompatible with my gcc version -



CUDA incompatible with my gcc version -

i have troubles compiling of examples shipped cuda sdk. have installed developers driver (version 270.41.19) , cuda toolkit, sdk (both 4.0.17 version).

initially didn't compile @ giving:

error -- unsupported gnu version! gcc 4.5 , not supported!

i found line responsible in 81:/usr/local/cuda/include/host_config.h , changed to:

//#if __gnuc__ > 4 || (__gnuc__ == 4 && __gnuc_minor__ > 4) #if __gnuc__ > 4 || (__gnuc__ == 4 && __gnuc_minor__ > 6)

from point on got few of examples compile, stops with:

in file included /usr/include/c++/4.6/x86_64-linux-gnu/bits/gthr.h:162:0, /usr/include/c++/4.6/ext/atomicity.h:34, /usr/include/c++/4.6/bits/ios_base.h:41, /usr/include/c++/4.6/ios:43, /usr/include/c++/4.6/ostream:40, /usr/include/c++/4.6/iterator:64, /usr/local/cuda/include/thrust/iterator/iterator_categories.h:38, /usr/local/cuda/include/thrust/device_ptr.h:26, /usr/local/cuda/include/thrust/device_malloc_allocator.h:27, /usr/local/cuda/include/thrust/device_vector.h:26, lineofsight.cu:37: /usr/include/c++/4.6/x86_64-linux-gnu/bits/gthr-default.h:251:1: error: pasting "__gthrw_" , "/* android's c library not provide pthread_cancel, check `pthread_create' instead. */" not give valid preprocessing token make[1]: *** [obj/x86_64/release/lineofsight.cu.o] error 1

as of examples compile reckon not driver problem, rather must have unsupported gcc version. downgrading not alternative gcc4.6 has whole scheme dependency @ point...

as pointed out, nvcc depends on gcc 4.4. possible configure nvcc utilize right version of gcc without passing compiler parameters adding softlinks bin directory created nvcc install.

the default cuda binary directory (the installation default) /usr/local/cuda/bin, adding softlink right version of gcc directory sufficient:

sudo ln -s /usr/bin/gcc-4.4 /usr/local/cuda/bin/gcc

gcc cuda debian

intellij idea - Update external libraries with intelij and java - simple plenty really. i'm using apache jars, i'll create changes jar's every often. these jars listed external libs in intelij (i.e classpath looking install dir of jar's). when create changes intelij doesn't seem know new implementation. have remove jar external library , re-ad it. does know have intelij picks changes automatically ? i've done clean , rebuild project had little effect. you can go preferences -> build, execution, deployment -> build tools -> maven -> importing , check box says import maven projects automatically . in mac, can command + shift + a , come in action reimport , click on reimport maven projects . intellij-idea
