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

Hi Majestio!

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

I did as you wrote. But the problem with linking.

I tried to build HelloWorld (with link error):

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

Hi, Kai!

I rebuilt the whole system of cross-compile again, and recorded all of his actions step by step. I note, in my opinion, the main points.

First part: make from .c source
========================================================
#!/bin/sh

export TARGET="i686-w64-mingw32.static"
export MXE="/home/majestio/Dev/cross/mxe/usr"
export PATH="$MXE/bin:$PATH"

# Step 1
$MXE/bin/$TARGET-gcc -c hello.c

# Step 2
$MXE/bin/$TARGET-gcc hello.o -o hello.exe
------------------------------------------------------------------------------
Result: ok
hello.exe was successfully launched on the Windows host

then ...

Secont part: make from .d source
------------------------------------------------------------------------------
#!/bin/sh

export TARGET="i686-w64-mingw32.static"
export MXE="/home/majestio/Dev/cross/mxe/usr"
export LLVM="/home/majestio/Dev/cross/llvm"
export DLANG="/home/majestio/Dev/cross/dlang/$TARGET"
export PATH="$MXE/bin:$LLVM/bin:$DLANG/bin:$PATH"

# Step 1
$TARGET-ldc2 -c -gcc=$TARGET-gcc -mtriple=$TARGET hello.d

# Step 2
$TARGET-gcc hello.obj \
-L$LLVM/lib \
-L$DLANG/lib \
-lphobos2-ldc \
-lcurl \
-ldruntime-ldc \
-v \
-o hello.exe

# Step debug
echo "Find libraries ..."
find $DLANG -type f | xargs grep -l "D14TypeInfo_Const6"
echo "For comparison with the specified path ..."
echo "$DLANG/lib"
------------------------------------------------------------------------------
Result: only produced .obj file

Yes. When I built the library, I inserted for your advice in ruttime/CMakeLists.txt:

set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_C_COMPILER i686-w64-mingw32.static-gcc)
set(CMAKE_CXX_COMPILER i686-w64-mingw32.static-g++)

Curl is present.

I used it.

... In general, do not grow coconuts :((

Hi 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

Hi Kai!

I'm sorry for what I lift up a very old topic. As I have been busy throughout the year. I tried to fulfill your advice. At the stage of construction of library occur errors.
Maybe I missed some stage of construction? Please help, what to look for?

Details:

1) Build llvm (all ok)

=================================================================
If I use "make -k" many *.obj files created. But restarting the "make -k" still fails.

misspelled, it was written:

Hi Majestio!

The MinGW target is currently broken. Therefore you get the compile errors in Phobos/druntime (the missing FILE type etc.)
