[Discuss-gnuradio] Re: Building CUDA with GNUradio issues

[Yu-Hua Yang]

I solved the issue

It wasnt a compatibility issue. I was able to build with gcc/g++ 4.3 that came with F10. 

The problem is the file: msdd_source_simple.cc is missing a #include <string.h>

Recommend adding that to the SVN repository.

Hi

I am having alot of problems building CUDA with the current CUDA-enable GUNRadio branch. I am using Fedora 10.

I followed the http://www.smallwhitecube.com/php/dokuwiki/doku.php?id=howto:gnuradio-with-cuda wiki and everything is fine up until trying to 'make' gpgpu-wip

I understand that we may need to use GCC 3.4 which I do by doing this command::
CC=gcc34 CXX=g++34 ./configure --with-cuda=/usr/local/cuda --with-cudasdk=/path/to/NVIDIA_CUDA_SDK

but this error continues to show up:

g++34 -g -O2 -Wall -Woverloaded-virtual -pthread -o .libs/test_runtime test_runtime.o  ../../../gnuradio-core/src/lib/.libs/libgnuradio-core-qa.so -L/usr/local/cuda/lib -L/root/NVIDIA_CUDA_SDK/lib -L/root/NVIDIA_CUDA_SDK/common/lib/linux -lcppunit -ldl /home/admin/gpgpu-wip/gnuradio-core/src/lib/.libs/libgnuradio-core.so -lcuda -lcudart -lcutilD /home/admin/gpgpu-wip/omnithread/.libs/libgromnithread.so -lrt -lfftw3f  -Wl,--rpath -Wl,/usr/local/lib

Is this related to not using the right gcc version? But I thought I took care of that issue. The wiki does say that gcc/g++4.1 was the one that was successful. But I cant seem to get gcc 4.1 working on my F10, just alot of issues with missing std header files to missing cpp and etc. I tried installing gcc4.1 from rpm as well as trying to build it from source, but both methods did not work.

Is gcc4.1 the only way to a successful CUDA-Enable GNUradio build?? gcc3.4 is not possible? I guess this is more of a linux question but how did you guys install gcc/g++4.1 on top of the later versions of gcc? There is no such rpm as compat-gcc-41 as there is for gcc3.4 so gcc 4.1 is rather a PITA

Please help!
