CUDA 3.0 and gcc 4.4.x
Thursday, October 21, 2010
Deadly combination! Compilation breaks when you try to do make on NVidia SDK example projects even. Problem is with nvcc incompatibility. A gcc version of 4.3.x works fine (as of this date).
Here is the compilation error listing:
/usr/include/string.h:43: error: inline function ‘void* memcpy(void*, const void*, size_t)’ cannot be declared weak
/usr/include/string.h:64: error: inline function ‘void* memset(void*, int, size_t)’ cannot be declared weak

Fixing the error basically means commenting out the specific lines in math_functions.h and common_functions.h on which the compiler shows the error (shown in dark blue).
Solution: comment them out. This will fix compilation errors. I have not tested the side-effect of this hack. But as for fixing compilation break, it works!
Note:
I needed a few more steps:
1. Uninstall gcc-4.4.x, g++-4.4.x (and all 4.4.x libraries)
2. Install gcc and g++ 4.3.x versions.
3. ln -s /usr/bin/gcc-4.3. /usr/bin/gcc
4. ln -s /usr/bin/g++-4.3. /usr/bin/g++
5. Install libXi-dev (since -lXi failed)
6. Install libxmu-dev (since -lxmu failed)
Steps 5,6 were required when I tried to build GL applications like fluidGL, simpleGL etc.
