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

I tried to build HelloWorld (with link error):
======================================================================
#!/bin/sh

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

$MXE/$TARGET/bin/ldc2 -v \
-mtriple=i686-w32-mingw32.static \
-gcc=i686-w64-mingw32.static-gcc \
-L=-L$MXE/$TARGET/lib \
hello_d.d
======================================================================

Trying to run the linker separately (with link error):
======================================================================
#!/bin/sh

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

$MXE/bin/$TARGET-ld -v \
hello_d.obj \
-o hello.exe \
-L$MXE/$TARGET/lib \
-lphobos2-ldc \
-lcurl \
-ldruntime-ldc \
-lws2_32 \
-lshell32
======================================================================

Output linker:
