I'm running into the same error. Correct me if I'm wrong. To build llvm, you'd need llvm-gcc front-end. You're saying we'd need llvm in order to build llvm-gcc. So how should we kick start the process? Thanks. Duncan Sands wrote: > > Hi Eliseu, > >> 2. I've unpacked llvm-gcc-4.2-2.6.source.tar.gz under the llvm-gcc >> directory. I've also

Hi Aaron, Duncan Thanks for the answers. >From Duncan's e-mail, I've tried to build llvm-2.6. First problem was a missing dependence on lbffi.so.4. But I've downloaded the source from redhat, compiled and passed that point. Now I have another missing dependence on GLIBCXX_3.4.9. The version in my system is 3.4.6-11. I've been looking around for a 3.4.9 rpm for redhat, could

Dear Anton, you can add your register allocator strait iin the "lib/CodeGen/Passes.cpp", and then 're-make' it: "makellvm llc", on the top of lib/CodeGen. It is faster than running make from LLVMOBJDIR. The problem is that it only add to llc the changes on the lib/CodeGen directory. If you change other parts, a make from LLVMOBJDIR will synchronize it. Try adding

I've read and followed the README.LLVM file that comes with LLVM-GCC 4.0 Front End source, but got the following error when compiling: configure: error: You must specify valid path to your LLVM tree with --enable-llvm=DIR make: *** [configure-gcc] Error 1 I've done the following in csh before hand: $ setenv LLVMOBJDIR /home/napi/proj/c2jvm/llvm/llvm-gcc/obj Where did I go wrong?

Hi! I've did what Jim Laskey wrote but llc didn't reckognize my regalloc option. So I moved my allocator implementation into seperate folder within CodeGen and wrote separate makefile for it (like in "Writing an LLVM pass" tutorial). But when I run "make" from LLVMOBJDIR it doesn't enter the RegAlloc directory and when linking llc an error like

If llvm is build with srcdir != objdir, building gcc will fail with ../../llvm-gcc4-1.7.source/gcc/llvm-internal.h:36:36: error: llvm/Support/DataTypes.h: No such file or directory This happens because DataTypes.h is a generated header. Adding -I$(LLVMOBJDIR)/include to INCLUDES in Makefile.in:878 solves the problem. One more thing, is the modified GCC available in some svn or cvs repository?

Hi, I recently bootstrapped gcc4 frontend on a i686-linux-gnu too. As I notice, if the llvm "tools-only " was build with srcdir != objdir , the building of llvm-gcc4-1.7.source encountered mistakes of unable to find some header files. So I just edited llvm-gcc4-1.7.source/gcc/Makefile.in and a line like this: INCLUDES += -I$(LLVMOBJDIR)/include With this change, the building errors

A clean build of revisions 12 or 13 of llvm-gcc4 produces: make[1]: *** No rule to make target `llvm-backend.c', needed by `llvm-backend.o'. Stop. While the gcc/Makefile.in has: llvm-backend.o : llvm-backend.cpp $(ALL_HEADERS) #line 2440 it also has: # APPLE LOCAL begin LLVM #line 1018 ifneq ($(LLVMOBJDIR),) OBJS-common += llvm-backend.o llvm-convert.o

Hi! I'm installing LLVM under Debian Linux. I've installed llvm-gcc3 binaries and am trying to build LLVM. I run make command from llvmobjdir and it builds Release configuration. I didn't set ENABLE_OPTIMIZED variable to 1 and I didn't configure LLVM with --enable-optimized switch. What can cause building Release configuration and how can I switch to Debug one? Thanks. Tony.

Hello Gordon Thank you for your reply When I tried building llvm-gcc from source I got the error: You must specify valid path to your LLVM tree with --enable-llvm=DIR I have tried setting $LLVMOBJDIR to the llvm folder, llvm/Release and llvm/bin, but I still get the same error.

Hi, I have seen the bug http://llvm.org/bugs/show_bug.cgi?id=896 Maybe it is a non-issue but I had some trouble with this. I am running Debian sid and were no longer able to compile llvm. /home/fred/llvm/build/gcc/xgcc: /home/fred/llvm/build/gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/libstdc++.so.6) The installed version have this symbol. strings

Hmm, there are other pages on the the website that tell you how you should configure gcc, e.g. you're led from "How to build the C/C++ Frontend" at http://llvm.org/docs/CFEBuildInstrs.html to Subversion HEAD (by virtue of an "svn co"). Then you're supposed to look at README.LLVM. And

I am trying to build the llvm-gcc frontend. I think I have followed the directions correctly. I am using cygwin on XP SP2 (uname -a reports: CYGWIN_NT-5.1 pad7 1.5.25(0.156/4/2) 2007-12-14 19:21 i686 Cygwin) gcc --version reports: gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125) Since there is no binary for llvm-gcc I am following the directions in the tar file for the 4.2 version. -

Another note: with this new functionality you should be able to dynamically load register
