similar to: Clang Cross compilation GCC Source Requirement

Hello, I need to build a CLANG cross compiler for mips-linux-uclibc. To be completely compatible with the target system, I would like it to use linux 2.6.32.54 headers, binutils 2.25, gcc 4.1.2, and uClibc 0.9.30.1 for the gcc toolchain. I have been able to build the GCC toolchain a variety of different ways, but none of these builds can be "dropped in" via clang as a replacement for

Hi Peter I guess this is the document written by you https://fosdem.org/2018/schedule/event/crosscompile/attachments/slides/2107/export/events/attachments/crosscompile/slides/2107/How_to_cross_compile_with_LLVM_based_tools.pdf I follow it to try to use the clang to do cross compilation. Actually, my target binaries is SPECCPU2006 and autotools based binaries. However, I failed on the first

Hi, I am trying to use LLVM/clang to build a binary for ARM Cortex M platforms. When I build my binary the linker fails to find these libraries. ./bin/clang++ -target arm-none-eabi -mcpu=cortex-m4 ./temp.cpp -L ./lib/ -L ./libexec/ -L ../build3_v7m/lib/ ld.lld: error: unable to find library -lunwind ld.lld: error: unable to find library -lc ld.lld: error: unable to find library -lm ld.lld: error:

Hi Joerg, Thank you very much! I finally found a working command string to cross-compile for ARM on x86. ./clang -v --save-temps -ccc-host-triple arm-none-linux-gnueabi --sysroot=/home/hum/Documents/Projects/arm_toolchain/arm-2010.09/arm-none-linux-gnueabi/libc -gcc-toolchain /home/hum/Documents/Projects/arm_toolchain/arm-2010.09 hello.c -o hello Above works fine! Important options are

Hello, With your kind concern and help, I now can make a binary for ARM target. ./clang -v --save-temps -ccc-host-triple arm-none-linux-gnueabi --sysroot=/home/hum/Documents/Projects/arm_toolchain/arm-2010.09/arm-none-linux-gnueabi/libc -gcc-toolchain /home/hum/Documents/Projects/arm_toolchain/arm-2010.09 hello.c -o hello The build command is shown above. After that, I prepared an ARM laptop,

Hello list I think I really finally found a way to crossbuild a binary for ARM using Clang/llvm. This message would be a documentation for someone who may concern for the same issue with me. - Target : TOSHIBA AC100 / Ubuntu 12.04 (https://wiki.ubuntu.com/ARM/** TEGRA/AC100 <https://wiki.ubuntu.com/ARM/TEGRA/AC100>) - Host : i386 Desktop PC / Ubuntu 12.04 - Toolchain on host : sudo

Hello, Thank you for your kind attention to my issue and your help. I changed the tool chain and tried again. And there is a little progress but still have some problem. Using --sysroot doesn't make clang use linker(ld) in the cross tool. Most important question is how I can make clang use cross tool linker. Let me show you my experiment and questions below. There are two questions. [Run]

Hi Daniel, I am on a vacation now till the Aug 3 but I can take a look at these problems. What is the most important? As to the issue #3 - do we need to keep compatibility with the old mips-mti-linux-gnu toolchain layout?

#1 is the most important but I'm already debugging that. I don't want to interrupt your holiday but if you could look at #3 that would be great. > As to the issue #3 - do we need to keep compatibility with the old mips-mti-linux-gnu toolchain layout? It would be nice to support both the old and new layouts but I doubt that's possible with the current framework (see below). If

Hello Gergö, Joerg and people on our list With your kind answer, I tried to build a hello world program for ARM(arm-none-linux-gnueabi) on my x86-64 PC. Thank you we verified the generated bitcode. The only thing remained is linking. Let me brief what I did so far. 1. Built Clang/llvm in a way explained in http://clang.llvm.org/get_started.html on Ubuntu 11.10 x86-64 PC 2. Downloaded gcc-4.0

Hi Journeyer First, thank you so much for your updates on your experiments. I am currently following your steps but have found myself stuck with the following error: /usr/lib/gcc/arm-linux-gnueabi/4.6/../../../../arm-linux-gnueabi/bin/ld: this linker was not configured to use sysroots clang: error: linker command failed with exit code 1 (use -v to see invocation) I used the command string you

Hi, Sorry for the late report but I've only just found these issues. Llvm.org isn't working for me at the moment but I'll file tickets once it is. The issues are: 1. Almabench has some significant numerical differences and fails the reference check for some configs. I'm investigating this one at the moment but early indications are that it's a similar (but different)

Sorry for not explaining well. After compiling with g++-cross g++-cross -c a.c I do link using this command /gold_binutils/build/gold/ld-new -plugin ~/Desktop/Sanjeev/LLVM/llvm-2.7/Release/lib/libLLVMgold.so --eh-frame-hdr -melf_i386 -dynamic-linker /lib/ld-linux.so.2 /usr/lib/crt1.o /usr/lib/crti.o /usr/local/lib/gcc/i686-pc-linux-gnu/4.2.0/crtbegin.o

You may also take a look at the ELLCC project (www.ellcc.org <http://www.ellcc.org/>). As far as I understand it they produce and package cross toolchains for a number of popular targets. - Matthias > On Aug 4, 2017, at 12:54 PM, Jonathan Roelofs via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > > > On 8/4/17 1:14 PM, Goran Mekić via llvm-dev wrote: >> On

Today, there're two different locations for runtimes files within Clang's installation: compiler-rt: headers: $prefix/lib/clang/$version/include(/sanitizer) libraries: $prefix/lib/clang/$version/lib/$os/libclang_rt.$name-$arch.$ext libc++, libc++abi, libunwind: headers: $prefix/include/c++/v1 libraries: $prefix/lib/$name.$ext The scheme used by libc++, libc++abi, libunwind
