Build for i586 #4013
Comments
|
This is perhaps due to the D runtime and stdlib being built for i686. You can build runtime and stdlib yourself using ldc-build-runtime, see: https://wiki.dlang.org/Building_LDC_runtime_libraries |
And how would it be more correct in my case to build libraries? I'm not really familiar with the necessary parameters to pass as flags. |

Can you try |

Something like: |

Sorry... i586 needed |
So your LLVM apparently defaults to i686. I'm not sure whether |

Yes, I did it! I have an

Great, so I guess compiling on that box is severely limited by CPU speed and available RAM. If you just want to cross-compile to that target, see https://wiki.dlang.org/Cross-compiling_with_LDC. You'll 'just' need an additional cross-gcc toolchain from your host to i586 (incl. all required C libs) to make cross-linking work. |
The problem is that I can't compile GCC, I always get this error: ...
checking for suffix of object files... mv -f .deps/findcomp.Tpo .deps/findcomp.Plo
configure: error: in `/root/source/gcc/9.5.0/build/i586-pc-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details
Makefile:14150: recipe for target 'configure-target-libgcc' failed

...I wrote about it in my very first post. |

Let's close this then, this was never an LDC issue per se. |

I am faced with a problem about compiling a compiler
ldcfor processorGeode LX800.The bottom line is that I have a processor on which I want to compile the program, is an
i586architecture.The official documentation says that "... the core is a combination of Intel Pentium ® processor, AMD Athlon™ processor, and AMD Geode LX processor specific instructions." - this means that the processor architecture is <
i686. And judging by the fact that Linux gives a description when callinguname:# uname -m i586This suggests that the processor is CLEARLY
i586. The problem is that I can't assemble the software I need for this processor, since it is automatically assembled fori686.What have I done?
I built an
ldccompiler on this machine:# ldc2 --version LDC - the LLVM D compiler (1.30.0-git-32f5a35): based on DMD v2.100.1 and LLVM 10.0.1 built with DMD32 D Compiler v2.086.1 Default target: i686-pc-linux-gnu Host CPU: geode http://dlang.org - http://wiki.dlang.org/LDC Registered Targets: x86 - 32-bit X86: Pentium-Pro and above x86-64 - 64-bit X86: EM64T and AMD64And when I try to compile the program through it, I create a binary file, but when I start it outputs Illegal instruction:
