similar to: [LLVMdev] llvm with non-standard gcc location

Hi all, I'd like to use LLVM 2.8 on a openSUSE 10.3 box and when I try to compile anything I get an error: martin at vm:~/project/backend> clang tutorial001.m -v -emit-llvm -o tutorial001 clang version 2.9 (trunk 122601) Target: x86_64-unknown-linux-gnu Thread model: posix "/usr/local/llvm/Debug+Asserts/bin/clang" -cc1 -triple x86_64-unknown-linux-gnu -emit-llvm-bc -disable-free

Can you add `--reproduce=repro` to lld command line? That generates repro.tar in your current directory which contains all input files. And then please compress and upload it somewhere so that we can take a look.

Alpine linux is a distribution that uses musl libc instead glibc. Here are my steps to reproduce: On Alpine linux, download LLVM, Clang, LLD 6.0.0 from releases.llvm.org, and build them from source. $ clang -c hello_world.c $ ld.lld --gc-sections -m elf_x86_64 -o hello_world /usr/lib/gcc/x86_64-alpine-linux-musl/6.4.0/../../../../lib/Scrt1.o

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 there, I compiled clang+gold using a gcc under path /s/gcc-4.3.1/bin/. Later on I do configure and make for flex-2.5.35, and the following command is invoked: "/path/to/my/gold/ld" --hash-style=gnu --no-add-needed --eh-frame-hdr -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 -o flex /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../crt1.o

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

Trivial hello world program compiles with -O3, but with -O4: (BTW, is there a guide to what different -On mean?) llvm-g++ -O4 Hello.cc -o Hello -v Using built-in specs.

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! Quick question - do you know if recent commits could cause this error, or I should go to bisect/debug this? Do we have tests that check that -gsplit-dwarf succeeds (i.e. compile and link step work)? $ cat a.cc int foo(int x) { return x + 1; } int main() { return foo(42); } $ ./bin/clang++ -gsplit-dwarf a.cc /tmp/a-005b1a.o(.debug_pubnames+0x6): error: undefined reference to

Please help me. How do I fix this bug @ubuntu:~/Documents/test$ clang hello.c -o hello /usr/bin/ld: cannot find crt1.o: No such file or directory /usr/bin/ld: cannot find crti.o: No such file or directory /usr/bin/ld: cannot find crtbegin.o: No such file or directory /usr/bin/ld: cannot find -lgcc /usr/bin/ld: cannot find -lgcc_s clang-2: error: linker command failed with exit code 1

Hi, I build llvm with gold plugin, clang and the binutils(and it's put into the PATH) with plugins support. ld.gold is renamed to ld. A quick test of clang -flto -O0 hello.c can succeed. But when I try to export CC="clang -v -flto" and compile MySQL, it failed in the linking with the following error message: "/home/ryan/binutils/bin/ld" -export-dynamic -z relro

Jack, I think there is an extra dimension to darwin that might be confusing things. Darwin uses two-level-name-space. That means that at build time the linker records where it found each dylib (SO) symbol. (It records the path the dylib supplied as its "install name" - not just the leafname as SO_NEEDED does.) On a SnowLeopard system you *can* link against /usr/lib/libgcc_s.

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

Nick, How exactly do you envision this being done? Looking at the contents of config/darwin.h, I see... /* Support -mmacosx-version-min by supplying different (stub) libgcc_s.dylib libraries to link against, and by not linking against libgcc_s on earlier-than-10.3.9. Note that by default, -lgcc_eh is not linked against! This is because in a future version of Darwin the EH frame
