Hi, I'm trying to cross-compile my app. #include <stdio.h> int main() { puts("test"); fopen("test", "r"); // removing fopen() call removes the error return 0; } clang -c -target x86_64-linux-gnu test.c ld.lld -v -o test -m elf_x86_64 -dynamic-linker /lib64/ld-linux-x86-64.so.2 /usr/lib/x86_64-linux-gnu/crt1.o /usr/lib/x86_64-linux-gnu/crti.o test.o

Thanks, Tim. You are right, it's using macOS' stdio.h, which is a terrible idea. Clang docs on --sysroot: When you have extracted your cross-compiler from a zip file into a directory, you have to use --sysroot=<path>. The path is the root directory where you have unpacked your file, and Clang will look for the directories bin, lib, include in there. I have a silly question: where

Sorry for the late reply. Thanks, Eli. That was really helpful.

Seeing as GCC 4.6 works without breaking to build LLVM instead of Clang I think I'm going to bug the Debian proper to make it easier for Clang/LLVM to get the linker update changes. After all, Debian's breaking an awful lot of stuff lately so it seems reasonable for them to add this to their To Do List. - Marc On 08/24/2011 07:15 PM, Eli Friedman wrote: > On Wed, Aug 24, 2011 at

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

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

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, It looks like I have found a bug in LLD. Suppose DSO defines a global variable 'data' and initializes it by the address of function 'set_data' defined in the same DSO. If an executable file (linked by LLD) gets address of the '&set_data' function and compares it with a value stored in the 'data' variable it gets different result. If the executable is linked

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

Yes, I had just reduced it too. I am pretty sure this was implemented at some point. Taking a look.

The short version is: assuming you have a cross-binutils installation using e.g. x86_64--netbsd-as and x86_64--netbsd-ld, you add a symlink called x86_64--netbsd-clang to clang and just call that with an appropiate --sysroot to make it find
