llvm dev - Nov 2005 - [LLVMdev] building LLVM 1.6 on Debian unstable ...

Hi,

Tried to build the 1.6 release on Debian unstable, but ran into link 
problems for some utils ...

Copying the messages when building llc, the same error occurs for lli, 
llvm-db and some of the examples. Is this a problem with the compiler 
version? LLVMSelectionDAG.o itself builds correctly.

make[2]: Entering directory `/home/sameerds/data/llvm-1.6/tools/llc'
llvm[2]: Linking Debug executable llc
`.gnu.linkonce.t._ZNK4llvm14TargetLowering12getValueTypeEPKNS_4TypeE'

The compiler is gcc 3.4.5 from Debian unstable.

I believe this is a binutils issue (ld belongs to binutils).
See for example:

Thanks! Downgraded the binutils package from 2.16.1cvs20050902-1 (Debian 
unstable) to 2.16.1-2 (testing). The message still appears, but no error 
is reported and the build completes. Found similar messages in what 
appears to be an automated daily build for ia64 ... assuming those 
messages can be safely ignored.

Would this information be useful in the release notes?

Sameer.
