In previous versions I used the linux32/dmd with the -m64 switch in order to generate 64-bit code. But this does not work anymore:

   $ linux/bin32/dmd
linux/bin32/dmd: /lib/libc.so.6: version `GLIBC_2.28' not found (required by linux/bin32/dmd)

The reason for presence of these symbol versions are memcpy and fcntl:

   $ nm --with-symbol-versions -D linux/bin64/dmd|grep GLIBC_2.14
                    U memcpy@GLIBC_2.14

   $ nm --with-symbol-versions -D linux/bin32/dmd|grep GLIBC_2.28
            U fcntl@GLIBC_2.28

Is it possible to build the compiler and the tools with more "backward compatible" glibc version numers like memcpy@GLIBC_2.2.5 and fcntl@GLIBC_2.2.5? IIRC this is accomplished by using

   asm (".symver memcpy, memcpy@GLIBC_2.2.5");
   asm (".symver fcntl, fcntl@GLIBC_2.2.5");

in the source code.

dmd version v2.089.0 should work for you, and you can use that to build a newer version of dmd. You can get it from http://downloads.dlang.org/releases/2019/

You can use this on an older Linux system to generate more compatible binaries, or you can try building static binaries. I've got a short guide for LDC on Alpine Linux in a docker container at https://d.minimaltype.com/index.cgi/wiki?name=statically-linked+binaries

... I'd hope that the version numbers aren't so meaningless that dmd could get away with just lying about them and not have horrible problems.

I'd prefer that dmd work out of the box on old Linux systems too, but you're probably past EOL in other big ways as well, there. A stock CentOS6 system comes with a root privilege escalation vuln in sudoedit

dmd version v2.089.0 should work for you,

2.098.0 in 64 Bit works for me as well. I used patchelf to change the dynamic loader and the rpath to use a local build of a more modern glibc.

I am the only user on my machine and know the root password. In environments with multiple non-root-users setuid-programs like sudo are usually not executable by untrusted users.

If you take a look at SUSE's products [1] you will find that SUSE Linux Enterprise Server 11 long term support ends as late as on 31 Mar 2022. Its glibc is based on GNU glibc 2.11.3.
