error: ‘memcpy’ was not declared in this scope

[davidcastells]

I got the error shown below compiling the library on my system, which has the following
characteristics:

• Ubuntu 16.04 LTS
• Cuda compilations tools v7.5.17
• gcc version 5.3.1

/usr/include/string.h: In function ‘void* mempcpy_inline(void, const void, size_t)’:
/usr/include/string.h:652:42: error: ‘memcpy’ was not declared in this scope
return (char ) memcpy (__dest, __src, __n) + __n;
^
Makefile:20: recipe for target 'xmp.o' failed
make: ** [xmp.o] Error 1

I actually fixed it by adding the _FORCE_INLINES definition on nvcc compiler flags

NVCC_FLAGS=-D_FORCE_INLINES ...

Thanks,

It looks like this issue is resolved in 8.0. Here is a page describing the workaround but I suspect you have already seen this.
