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?
IMO you should really be building your app on an older Centos version (5 or 6). Then your binary should run everywhere, though it may sometimes require installing a -compat package.
That causes a number of other problems,
can you please provide some details? I'm genuinely curious as I've been faced with this occasionally and the only problem I've encountered is having to install a few *-compat packages. thanks.
when the only issue is accessing a working version of memcpy from the installed glibc.
