Can any Linux guru please help me decipher the following inscrutable error message encountered when trying to build hello world on a Linux cluster that I don't have admin privileges to:

dsimcha@canton:~$  dmd/linux/bin/dmd hello.d
/usr/bin/ld: skipping incompatible

--- errorlevel 1

The DMD version is 2.026.  An identical error message occurs on D 1.041.  I know the Linux distro on this cluster is fairly new since the kernel is 2.6.27, but that's about it.  For all I know, a trained monkey could have set the stupid thing up.  Any suggestions on where to start troubleshooting something like this?

Looks like you're trying to link with the 64 bit library when you need the 32 bit one. x86_64 means 64 bits. The 32 bit versions may not be installed.

Duh, didn't notice that x86_64 in there.  Good call.  I guess I should nag the sysadmin to install the 32-bit versions.  Thanks.

For whatever reason, with some distro's they are installed but not on the linker path by default.
