[LLVMdev] Problem building llvm after r109996 (Add InitializeNativeTargetAsmPrinter())
Hello,
After I try making a clean build and got the following error:
llvm[3]: Compiling EDDisassembler.cpp for Release build
In file included from /llvm/include/llvm/Target/TargetSelect.h:38,
from /llvm/lib/MC/MCDisassembler/EDDisassembler.cpp:37:

==== config
Darwin10 x86_64 (and llvm-gcc from Xcode 3.2.3).
../configure --prefix=/opt/llvm-selfhost --without-llvmgcc --without-llvmgxx
--disable-bindings --disable-assertions --enable-optimized
--enable-targets=x86,x86_64 CC=llvm-gcc CXX=llvm-g++
==
Is somebody else having trouble with this change ?

Hi Jean-Daniel, My fault, I'm sure, but I don't see the problem yet. Is it possible your version of llvm/Config/AsmPrinters.def has X86 listed twice? - Daniel On Mon, Aug 2, 2010 at 12:43 AM, Jean-Daniel Dupas <devlists at shadowlab.org> wrote:> Hello, > > After I try making a clean build and got the following error: > > llvm[3]: Compiling EDDisassembler.cpp for Release build > In file included from /llvm/include/llvm/Target/TargetSelect.h:38, > from /llvm/lib/MC/MCDisassembler/EDDisassembler.cpp:37: > /llvm/stage1/include/llvm/Config/AsmPrinters.def: In function ‘void LLVMInitializeX86TargetAsmPrinter()’: > /llvm/stage1/include/llvm/Config/AsmPrinters.def:27: error: redefinition of ‘void LLVMInitializeX86TargetAsmPrinter()’ > /llvm/stage1/include/llvm/Config/AsmPrinters.def:27: error: ‘void LLVMInitializeX86TargetAsmPrinter()’ previously defined here > make[3]: *** [/llvm/stage1/lib/MC/MCDisassembler/Release/EDDisassembler.o] Error 1 > > > ==== config > > Darwin10 x86_64 (and llvm-gcc from Xcode 3.2.3). > > ../configure --prefix=/opt/llvm-selfhost --without-llvmgcc --without-llvmgxx --disable-bindings --disable-assertions --enable-optimized --enable-targets=x86,x86_64 CC=llvm-gcc CXX=llvm-g++ > > ==> > Is somebody else having trouble with this change ? > > > -- Jean-Daniel > > > > > > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev >

[LLVMdev] Problem building llvm after r109996 (Add InitializeNativeTargetAsmPrinter())
The problem is with llvm/Config/Targets.def If you pass --enable-targets=x86,x86_64 in the configure invocation, the generated Targets.def file contains 2 times LLVM_TARGET(X86) as they map both to the same native target. If you don't use the '--enable-targets=' option while configuring LLVM, LLVM_TARGET(X86) is inserted only once, that's why it works. I guess that until the change introduce by r109996, all files where gracefully handling the duplicate entry. I think I can safely workaround this issue by removing either x86 or x86_64 in my configure invocation.
