digitalmars.D.ldc - How to build a set of toolchains for cross-compiling for LDC?
- Majestio (19/19) Jun 28 2015 Hi all!
- Kai Nacke (9/29) Jun 28 2015 Hi Majestio!
- Majestio (147/149) Jul 14 2015 I did as you wrote. But the problem with linking.
- Jacob Carlborg (32/49) May 17 2016 I've successfully cross-compiled using LDC and ELLCC.
Hi all! I apologize in advance for my English, I use Google Translator :-\ I became interested in the D programming language recently. I want build a comfortable environment for cross-compilation. In my Linux Funtoo already has a similar environment for C/C++ based http://mxe.cc: i686-w64-mingw32.shared i686-w64-mingw32.static x86_64-w64-mingw32.shared x86_64-w64-mingw32.static ... and more libs, including Qt 5.4.2 for each toolchain. So far I have built native LDC, and native "Hello world" is compiled and linked successfully. Actually, the question is how to build step by step for the environment LDC for cross-compile, similar MXE? Just in case, my directory structure: /home/majestio/dev/cross/mxe - C/C++ cross-compile env /home/majestio/dev/cross/llvm - LLVM,Clang,LDC WBR

You need to compile LLVM for the targets you want. With USE flag multitarget, LLVM is build for all available targets. Then rebuild LDC with this LLVM. I described cross-compiling for AArch64 here: http://forum.dlang.org/post/fhwvxatxezkafnalwhqr forum.dlang.org Regards, Kai

But the problem with linking.What can be done?Hi Majestio! First, your link command is definitively incomplete. At least libc and libpthread are missing. You are using ld so I miss the crt*.o files, too. I would recommend to use the cross-gcc for linking. Symptons for this are:hello_d.obj:(.text[_main]+0x7): undefined reference to `__main' hello_d.obj:(.text[__D3std5stdio16__T7writelnTAyaZ7writelnFAyaZv]+0x3a): undefined reference to `__mingw_fprintf'These are symbols from the MingW C library. BTW: Can you cross-compile a C hello world without problems? Did you compile druntime and phobos for the mingw target? If yes where did you place the libraries? The other missing symbols are from druntime and phobos. This indicates that these libraries are not found. Did you also cross-compile the curl library? You can use the -v command line option with ldc2 to see the call to gcc. This is useful for debugging. Regards, Kai

You need to add -mtriple=i686-w64-mingw32.static to D_FLAGS variable in runtime/CMakeLists.txt and recompile the libraries. What happened is that the object files in the library are ELF-64 (compiled for x86-64 Linux) but hello.o is 80386 COFF. Therefore the unresolved references. What I miss is the error message from the linker, complaining about the architecture mismatch... Regards, Kai

But restarting the "make -k" still fails. WBR, MajestioJust in case the attached file: https//yadi.sk/d/bdD44pMYhvEG8Hi Majestio! The files were helpful. You need to add -mtriple=i686-w64-mingw32.static to D_FLAGS variable in runtime/CMakeLists.txt and recompile the libraries. What happened is that the object files in the library are ELF-64 (compiled for x86-64 Linux) but hello.o is 80386 COFF. Therefore the unresolved references. What I miss is the error message from the linker, complaining about the architecture mismatch... Regards, Kai

I want build a comfortable environment for cross-compilation. In my Linux Funtoo already has a similar environment for C/C++ based http://mxe.cc: i686-w64-mingw32.shared i686-w64-mingw32.static x86_64-w64-mingw32.shared x86_64-w64-mingw32.static ... and more libs, including Qt 5.4.2 for each toolchain. So far I have built native LDC, and native "Hello world" is compiled and linked successfully. Actually, the question is how to build step by step for the environment LDC for cross-compile, similar MXE? Just in case, my directory structure: /home/majestio/dev/cross/mxe - C/C++ cross-compile env /home/majestio/dev/cross/llvm - LLVM,Clang,LDCI've successfully cross-compiled using LDC and ELLCC. These are the steps I took to cross-compile from OS X to Linux 1. Download the ELLCC compile [1], pick the platform for which you'll be running the compiler 2. Download LDC for both OS X and Linux 64bit [2] 3. Symlink ellcc/bin/ecc to ellcc/bin/ecc-x86_64-linux. Do the same for ecc++ 4. Copy all files in ldc2-0.17.1-linux-x86_64/lib to dc2-0.17.1-osx-x86_64/lib and add a "x86_64-linux" prefix to the name of the library files 5. Copy ldc2-0.17.1-osx-x86_64/etc/ldc2.conf to ldc2-0.17.1-osx-x86_64/etc/ldc2-x86_64-linux.conf 6. Modify ldc2-0.17.1-osx-x86_64/etc/ldc2-x86_64-linux.conf to use the library files with the "x86_64-linux" prefix 7. Create a new C (backtrace.c) file with the following content: #include <stdlib.h> int backtrace(void **buffer, int size) { return 0; } char **backtrace_symbols(void *const *buffer, int size) { return NULL; } void backtrace_symbols_fd(void *const *buffer, int size, int fd) {} Compile with "ellcc/bin/ecc-x86_64-linux backtrace.c -c -o backtrace.o" 8. Compile a D program with: CC=ellcc/bin/x86_64-linux-ecc++ ldc2-0.17.1-osx-x86_64/bin/ldc2 -mtriple=x86_64-uknown-linux -conf=ldc2-0.17.1-osx-x86_64/etc/ldc2-x86_64-linux.conf backtrace.o main.d The only issues is that musl, the C standard library used by ELLCC is missing three symbols. I created a file backtrace.c with stubs for these symbols. [1] http://ellcc.org/releases/ [2] https://github.com/ldc-developers/ldc/releases/tag/v0.17.1 -- /Jacob Carlborg
