similar to: Problem in installatin under Unix

The problem was solved by setting environment variable CXX. But somehow a new one came. The gcc is installed in /usr/local/gcc-4.2.3. I managed to change clang/lib/Frontend/InitHeaderSearch.cpp clang/lib/Driver/ToolChains.cpp to force clang use the crt lib for that version. For details, plz see http://www.advogato.org/person/redi/diary/228.html. So now I have no problem of using clang to

Hi, I've restarted my Elsa/LLVM project after three months of having real life intrude. I upgraded my LLVM source to the current trunk. I had to make a few changes to my source, e.g. LLVMFoldingBuilder became IRBuilder and several instances of "new" became "Create". Now, a test case that previously succeeded fails. I run the following script: #!/bin/sh if [ 1 -ne 0 ]

Hi, I'ma having some troubles installing R under Unix. As it is written in the "how to install R" the ./configure passed on but when I type make I recieve this error message : gmake[1]: Entering directory `/usr/local/R_HOME/R-2.4.0/m4' gmake[1]: Nothing to be done for `R'. gmake[1]: Leaving directory `/usr/local/R_HOME/R-2.4.0/m4' gmake[1]: Entering directory

Are you saying this is this the first time you've tried to compile it on the cluster? It's easy to determine if g++ is installed and in the PATH - just get a console on the cluster and type "g++". However, AFAIK cluster nodes are not usually configured for software development, are they? Typically you build your code locally and then job it out to the cluster? Greg

I've compiled llvm several times, but this is the first time I saw this error when I was trying to compile it in a cluster. checking tool compatibility... configure: error: g++|clang++|icc required but not found I am pretty sure g++ is installed and in the path. I then downloaded clang++ binary and set path. The error was still there. OS: opensuse 10.1 gcc, g++ version: 4.2.3 Any idea? Bo

Dear friends, I am trying to install R-2.4.1 from source on Solaris 11 x-86. 64 bits, running on Sun Ultra-20 workstation, and using the SunStudio 11 compilers. I was able to "configure" R correctly, but received an error in "gmake", aparently related to bzip2 which I have been unable to debug. The messages are listed below. The configure.log and configure.status files are

Thanks Jonas, I wasn't aware of the gold linker plugin. Here's what I do, in my current workflow. First, I use clang to compile each .c file (e.g. for the bzip2 benchmark, or any other) into a .bc file: specmake clean 2> make.clean.err | tee make.clean.out rm -rf bzip2 bzip2.exe *.o *.fppized.f* find . \( -name \*.o -o -name '*.fppized.f*' \) -print | xargs rm -rf

Hi, It was suggested that I post my question regarding a LLVM 3.4 performance regression to this mailing list, rather than stackoverflow. So here is the link: https://stackoverflow.com/questions/22902034/llvm-3-4-performance-regressed Thanks :) Jens -- Jens Tröger http://savage.light-speed.de/

I am trying to compile R-devel (R-devel_2006-05-17.tar.gz) on Red Hat Enterprise Linux AS release 3 (Taroon Update 7) using the Portland Group compiler 6.0. (I have not yet successful compiled R on this configuration, so I don't know if this is a new problem.) I get an error pgcc -L/usr/local/pgi/linux86-64/6.0/libso -L/usr/lib64 -o dftables dftables.o ../dftables chartables.h

Hi Samba I noticed that the crc32 function in lib/crc32.c is somewhat inefficient. This little patch will reduce the inner loop from 10 instructions to 8 instructions on x86 with gcc. gcc can't figure out this simple optimization by itself on x86. Further optimization is possible by using the impl. in the linux 2.5 kernel, but I don't know if it is worth it. Is crc32 common in samba?

Hi all, I've encountered a build error with the latest R source (2.8.1). This is a relatively fresh install of OS Leopard (10.5.6), latest developer tools installed, gcc/g++/gfortran version 4.4 installed (via http://hpc.sourceforge.net/, after which I updated the gcc & g++ symlinks to link to the 4.4 versions; gfortran used the 4.4 version without updating the symlink). Ultimately I

Windows.h is part of Microsoft's Platform SDK that's bundled with Visual Studio. It should never have been in the llvm source tree. Why don't you have it? You have VC++, right?

Please see the documentation: https://xiph.org/ogg/doc/framing.html I would encourage you to use random serial numbers, as intended, also, as any downstream consumers of your files will face limitations similar to the ones you are facing if they want to do anything more with them. But before you go too far down the route of changing the serial numbers, can you tell us what software is

I faced with problem about CRC32 calculation, I see that lookup table is different here https://github.com/rillian/rogg/blob/master/rogg.c#L196 end for example here https://stackoverflow.com/a/18639975/1879101 - JS code on this page for building the table produces the same result. I think that generating the table is better than having hardcoded one - for security against the case when somebody

Hi there, I was trying to see what kind of informations I can get on dependence/alias analysis from the trunk llvm, and stumbled upon two potencial problems. First of all, the most recent documentation I could find online <http://llvm.org/docs/AliasAnalysis.html> suggests the use of options not available on the code (like enabling globalsmodref-aa, or count-aa, for example). Is there a more

I found 179 more *.{c,cpp,h} files with tabs.

Hi, I use the llvm::ExtractCodeRegion to extract each loop into a separate function, but I have a problem when I run this on the SPEC CPU 2006 on the 401.bzip2 benchmark. First I use clang -O3 to generate optimized llvm code and then I extract some loops from the module built from blocksort.c source file. The problem is that the PHI nodes contained in the successors of the codeRepl
