hi there, I have tried to building LDC 1.20.1 from src for ubuntu 14.04 i686 system. But got trouble in the building step, it seems that it always trying to building runtime for x86_64 target, no matter what kind of D compiler is using, I have tried with ldc2-1.2.0-linux-x86 or the latest dmd 2.091.0-0_i386. I also tried to using the cross-compiling style to build runtime adding `mtrip=i686-linux-gnu`, but the final ldc2 failed to link when building a simple empty D source file saying ``` /usr/bin/i686-linux-gnu-ld.gold: error: /usr/lib/gcc/i686-linux-gnu/6/crtbegin.o: incompatible target /usr/bin/i686-linux-gnu-ld.gold: error: /usr/lib/gcc/i686-linux-gnu/6/crtend.o: incompatible target /usr/bin/i686-linux-gnu-ld.gold: warning: skipping incompatible /home/chiot/ldctool/ldc2-tmp/bin/../lib/libdruntime-ldc.a while searching for druntime-ldc /usr/bin/i686-linux-gnu-ld.gold: error: cannot find -ldruntime-ldc /usr/bin/i686-linux-gnu-ld.gold: warning: skipping incompatible /usr/lib/gcc/i686-linux-gnu/6/libgcc_s.so.1 while searching for libgcc_s.so.1 /usr/bin/i686-linux-gnu-ld.gold: warning: skipping incompatible /usr/lib/gcc/i686-linux-gnu/6/libgcc_s.so.1 while searching for libgcc_s.so.1 /usr/lib/gcc/i686-linux-gnu/6/../../../../lib64/crt1.o(.text+0x20): error: undefined reference to 'main' xx.o:xx.d:function ldc.register_dso: error: undefined reference to '_d_dso_registry' collect2: error: ld returned 1 exit status Error: /usr/bin/cc failed with status: 1 ``` so, the ldc2 now is sticking to x86_64 for PC now?

With the little information you gave, it looks like the LLVM you use defaults to the x86_64 triple (can be configured via CMake when building LLVM), that's why you need -mtriple to build the libs, and later too when compiling any D file.
