Hi, I am trying to compile glibc on Linux using llvm. I need to do this for a research project. The problem is that llvmc doesn't work, and I guess I have to set CC=llvmc to get the glic compiled. For some reason llvmc complains that it cannot find %llvmcc1%. I have this problem both on my Mac and my Linux system. Other tools that I have tested including llvm-gcc work without any problem. First, I appreciate it if you let me know what can cause this problem and second, tell me if you think I have any chance to compile glibc using LLVM. Thank you, Babak --------------------------------------------------------------- Babak Salamat PhD Student Department of Computer Science School of Information and Computer Sciences University of California, Irvine email: bsalamat at uci.edu web: www.ics.uci.edu/~bsalamat ---------------------------------------------------------------
Babak,
As its manual page (http://llvm.org/docs/CommandGuide/html/llvmc.html)
states, llvmc is an experimental tool:
llvmc is considered an experimental LLVM tool because it has these
deficiencies:
Poor configuration support
The support for configuring new languages, etc. is weak. There
are many command line configurations that cannot be achieved
with the current support. Furthermore the grammar is cumbersome
for configuration files. Please see http://llvm.org/PR686 for
further details.
That said, you should be able to get it to work with llvm-gcc.
Did you build llvm-gcc? Did you check the paths in the "c" config
file?
Did you install the config files?
All of these things need to be done in order for the standard config
file to work.
Reid.

Reid, Thank you for your quick reply. Yes, I have built and installed llvm-gcc and "llvm-gcc --print-prog- name=cc1" return the correct path for cc1, so I assume its path is set correctly in the config files, but I haven't installed config files separately. Do I need to do that? Is there any documentation about it?
