[LLVMdev] Building LLVM 2.7 on OpenSolaris

[Laszlo Kiss]

The build process fails to link the LLVM tools. Specifically, the  
first tool to build is 'opt' which results in 700+ undefined symbols.

I looked into the Makefiles and found that the "LINK_COMPONENTS" make  
variable does not get the correct set of libraries. In fact, at the  
top level Makefile.rules, the variable is set to "support system",  
however, these do not seem to make it to the 'opt' make context.

The list of libraries for 'opt' is (from the g++ link command):

... -lLLVMipo -lLLVMScalarOpts -lLLVMInstrumentation -lLLVMAsmParser - 
lLLVMBitWriter -lLLVMBitReader ...

It is missing at a minimum LLVMCore, which when added reduces the  
unresolved externals to 400+.

Guidance about how to deal with the link process would be great.
