similar to: [LLVMdev] Is -O4 supposed to work on linux ?

I got this one fixed by rebuilding llvm Debug (oups). I had an old version. I now seem to have a classical message: version GLIBCXX_3.4.14 not found. I am indeed building llvm-gcc using gcc4.5. Is this the problem ? The fix to this problem indicated in README.LLVM does not help .. Thanks Romain On Thu, Aug 12, 2010 at 6:43 PM, Romain Pechayre <rpechayr at gmail.com> wrote: > Thanks.

Thanks. It worked for a few more compilation lines. I now get the following linker error: undefined reference to llvm::MemoryBuffer::getNewMemBuffer(unsigned long, llvm::StringRef) I am surprised since the linker compile line already links with a whole bunch of llvm libraries ...

Ok. Thank you for your input. New questions :) : - Is the dev package basically the source code of gcc 4.2 ? Isn't it already fully included in llvm-gcc code base ? - How should I include bison+flex when I have installed Do I need to put additional flags to configure script ?

Hello all, I am trying to build the latest version of llvm-gcc on a x86_64 architecture running a Linux distribution. Using the READM.LLVM I have managed to run ./configure using appropriate options, but when I try to build using make, it shows the following error message after a few seconds: ../../llvm-gcc/gcc/gengtype-lex.l:31:27: fatal error: gengtype-yacc.h: No such file or directory. This

You'll need to install the dev packages for gcc 4.2.

OS: RHE 3, kernal 2.4.21-32.0.1EL Samba version: samba-3.0.20 Removed RHE version of samba and compiled/installed samba-3.0.20. After running about 30-60 minutes, I get the following syslog msg: "winbindd: Exceeding 200 client connections, no idle connection found" Eventually this grinds the whole system to a halt, and remote & console logins become impossible while samba is

Hello all, I am trying to build the kaleidoscope sample code on Mac os (10.6). What I have done to get llvm libraries : 1) Downloaded llvm-2.6 source code 2) ./configure 3)make 4) make intall Then I tried to build kaleidoscope as described in the tutorial: g++ -g -O3 toy.cpp `llvm-config --cppflags --ldflags --libs core` -o toy I get typical link time errors (undefined symbols: ...) as if the

Indeed it works. Thanks ! Is LLVM built with m32 by default ?

Hi, all I use llvm-gcc -O4 to compile SPEC 2000, some benchmarks can't be built successfully, such as 164.gzip, 175.vpr etc. The error messages are as follows. .. zh.o unlzw.o unpack.o unzip.o util.o zip.o -o gzip bits.o: file not recognized: File format not recognized collect2: ld returned 1 exit status specmake: *** [gzip] Error 1 specmake options 2> options.err |

Hi, I need advice in instrumenting programs using liblto and gold plugin. Specifically, I added my pass in tools/lto/LTOCodeGenerator.cpp. My pass inserts functions (myLoad and myStore) for some load and store instructions. The functions exist in a library file. I found that the approach works for the example in the link: http://llvm.org/docs/GoldPlugin.html $ llvm-gcc -flto a.c -c -o a.o $ ar q

Hi All, I am migrating a build system of an existing project from 'Object files' based executable generation to 'LLVM Bitcode' files based exe generation and applying OPT pass to LLVM Bitcode. I found out the following 4 step procedure. Please let me know if this is the right procedure or is there any other easy way of doing it. I need to modify 'Makefile' accordingly. I

Hi, I have the following function: TEST <- cbind(Pox0t30.stone.1990.2000, sqrt(apply(Pox0t30.stone.1990.2000[,2:11], 1, var))) In rhe resulting Object TEST the added column is titled: sqrt(apply(Pox0t30.stone.1990.2000[,2:11], 1, var) I would like to change it to a sensible variable name like PoxMean. How can I incorporate this into the above function? Ulrich --

Chris, Thanks for the hint. Moving over the libLTO.dylib from llvm 2.5 solved all of the linkage errors. I was able to completely build xplor-nih at -O4 now. The core xplor and xplor-tcl testsuite show no regressions. I do get 7 testcases in the xplor-python testsuite failing with bus errors now. The xplor-tcl and xplor-python tests are all run by tcl and python respectively loading their
