Hi, For the record, adding UNIVERSAL_SDK_PATH=/Developer/SDKs/MacOSX10.4u.sdk/ was insufficient to restrict the .a/.o files to link against the 10.4 sdk, but env MACOSX_DEPLOYMENT_TARGET=10.4 make did the trick.

[LLVMdev] configuring LLVM 2.6 for OSX 10.4sdk on OSX 10.5 system
Hi all,
(Sorry if the answer to this is obvious - and thanks in advance~)
Short version:
linker error of _backtrace from LLVMSystem.a building a dynamic
library embedding LLVM/clang, both against the OSX 10.4 sdk.
Long version:
I've just tried rebuilding my project using the 2.6 release, using the
following commands to try and force LLVM to build against the OSX 10.4
sdk (I am actually doing this on an OS X 10.5.8 system):
env MACOSX_DEPLOYMENT_TARGET=10.4 ./configure --enable-targets=x86 --
enable-jit --enable-optimized --enable-pic
env MACOSX_DEPLOYMENT_TARGET=10.4 make UNIVERSAL_SDK_PATH=/Developer/
SDKs/MacOSX10.4u.sdk/
This seems to work fine.
However, my project is a dynamic library in which LLVM/Clang are
embedded for adding runtime JIT capability to an existing application,
but in attempting to build, I get a linker error on _backtrace from
LLVMSystem.a.
Is this a simple mistake on my part, or is LLVM not supported against
the 10.4 sdk? The problem disappears if I build against 10.5 sdk
(using llvm-gcc 4.2), but unfortunately that's not possible for the
application in question. Here's the (abriged) build command:
