Unless I'm missing something, the problem lies directly with the fact that you are trying to do a link-stage operation with the GCC frontend. GCC, by default, probably runs "ld" or another system linker, which grabs the executable from binutils. This linker hasn't been modified (yet) to include support for .bc files, but you're compiler is emitting byte code to the *.o files. That is why the linker barfs, and tries to interpret as a script.
<br><br>I am actually planning on working on integration between binutils' ld and LLVM to allow just this functionality. I'll be working on this over the holidays, and hopefully will get something working by mid January. Until then, directly using the LLVM linking facilities to handle the bytecode is probably the best if not only option.

Hi,<br><br>I'm trying to compile some apps with the new llvm-gcc4 on amd64 linux<br>to .bc files, rather than to the native code. The same process I used to<br>build those apps before with llvm-gcc3 doesn't work:<br><br>
1)
<br>export CC=llvm-gcc CXX=llvm-g++ CFLAGS="-g -fno-inline" CXXFLAGS="-g<br>-fno-inline"<br>2) cd <whatever-app>; ./configure<br>3) make CFLAGS+=-emit-llvm CXXFLAGS+=-emit-llvm<br>[Reid told me not to pass -emit-llvm to configure scripts.]
<br><br>The process fails for the same reason on several apps I tried:<br><br>--------------------------------------------------------------<br>$ llvm-gcc -shared .libs/libdspam.o .libs/heap.o .libs/diction.o<br>.libs/base64.o .libs/buffer.o .libs/util.o .libs/nodetree.o
