Hi --
I'm trying to build an application on CentOS 7 which can run on older versions of CentOS. I'm running into problems with versioning of memcpy in Glibc. Executables built on CentOS 7 require memcpy from glibc-2.14, which causes the program not to load on systems with older versions of glibc.
My online search suggests to add an asm() with a .symver option to select memcpy from glibc-2.2.5 in each of the source files which reference memcpy(). This isn't practical with a program with tens of thousands of source files.
Does anyone have a reasonable solution?
