Bug 14942 – dmd linking error with SHA and SSSE3

I have a strange problem with building vibe.d in debug[0] As I updated to dmd-2.068 and the problem remains, I tried to minimize the test case and here it is. Code: import std.digest.sha; void main() { SHA1 hash; hash.put(cast(ubyte)0); hash.finish(); } And now with commands generated by dub: dmd -c -oftest.o -debug -g -w app.d dmd -oftest test.o -L--no-as-needed -g Results in: test.o: In function `std.digest.sha.SHA!(512, 160).SHA._sharedStaticCtor330()': /opt/dmd-2.068/import/std/digest/sha.d:224: undefined reference to `std.internal.digest.sha_SSSE3.transformSSSE3(uint[5]*, const(ubyte[64])*)' In release, problem does not occur. It's also ok with ldc2-0.15.1 DMD version: v2.068.0 OS: Gentoo linux x86_64 CPU: i5-2500K SandyBridge (with SSSE3) Config [/opt/dmd-2.068/bin/dmd.conf]: [Environment] DFLAGS=-I/opt/dmd-2.068/import -L--export-dynamic -defaultlib=phobos2 -L--demangle=dlang [Environment32] DFLAGS=%DFLAGS% -L-L/opt/dmd-2.068/lib32 -L-rpath -L/opt/dmd-2.068/lib32 [Environment64] DFLAGS=%DFLAGS% -L-L/opt/dmd-2.068/lib64 -L-rpath -L/opt/dmd-2.068/lib64 [0] https://github.com/rejectedsoftware/vibe.d/issues/1097

I can't reproduce this. What package did you install? What happens if you build D 2.068 from source (e.g. using Digger)?

I've tried it with the gentoo dlang overlay [1] There is not yet an ebuild for 2.068 so I tried that from binary package [2]. Thanks for pointing me to digger, I tested it with: ./digger build v2.068.1-b2 sudo ./digger install and it built! With ./digger build v2.068.0 it won't. When I tried to bisect it, it became strange as it was ok even with 2.068.0. So it seems to be something with the system configuration. When I manually passed the --conf pointing to diggers dmd.conf it was also ok. I guess it had to be something with the phobos lib. Maybe shared phobos lib used by gentoo ebuild mixed with static libs? So I unmerged all dlang ebuilds, checked bin and lib paths for remaining files and installed dmd manually from zip file. After that it builds ok, so problem solved. [1] https://github.com/gentoo/dlang/blob/master/dev-lang/dmd/dmd-2.067.1.ebuild [2] http://downloads.dlang.org/releases/2015/dmd.2.068.0.zip

sorry wrong issue tracker. this is a LDC or arch bug.
