Everytime I try to build something simple I always run into this issue:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
When I add -wc-use-mingw-linker however I can compile without issues. I've followed some steps I found in issues here like setting the COMPILER_PATH, but it doesn't fix the problem. I'm using MXE (although it also happens without this), and clang 3.8.
Any help would be greatly appreciated!
(although it also happens without this)
What distribution are you on?
Im on Ubuntu Xenial
This is a clang issue. Linking with -L /usr/lib/gcc/<arch>-w64-mingw32/5.3-<posix|win32> (i.e.: w32-clang test.c -L /usr/lib/gcc/i686-w64-mingw32/5.3-posix) fixes the linker errors.
I will try to integrate this into wclang within the next few days.
Awesome thanks!
Getting similar under Debian 8. However, for me it is:
/usr/bin/i686-w64-mingw32-ld: cannot find -lgcc
/usr/bin/i686-w64-mingw32-ld: cannot find -lgcc_eh
/usr/bin/i686-w64-mingw32-ld: cannot find -lgcc
/usr/bin/i686-w64-mingw32-ld: cannot find -lgcc_eh
Your suggestion helped me, too - thanks for that.
Mm, with the new version I still have this issue. I've got a docker image that reproduces this issue. Maybe it's something I'm doing wrong with the configuration.

Adding -wc-use-mingw-linker solves the issue. And I get a proper functioning exe.
Any clues on what I'm missing? Any help would be greatly appreciated.
I can't work around the cannot find crt2.o: No such file or directory issue. You must report it to the llvm people if you want to have it fixed. Or try Clang <= 3.6.
Mm Ill do that.. But what about the gcc_s?
For completeness, here is the output when I add -wc-use-mingw-linker:
w64-clang++ HelloWorld.cpp Hello/Speaker.cpp -IHello -ohello_world.exe -wc-use-mingw-linker -v

What I find interesting is that here a path is added to the crt2.o (/usr/src/mxe/usr/lib/gcc/x86_64-w64-mingw32.static/5.3.0/../../../../x86_64-w64-mingw32.static/lib/../lib/crt2.o) etc files. Is clang responsible for the call to collect or wclang?
I also tried to use clang 3.6 but ran into the exact same issue. It really feels like I'm configuring something incorrectly but I can't seem to spot it...
Trying with ubuntu thrusty and clang 3.5 next.
It works like a charm under Ubuntu trusty. What has changed?
Mm Ill do that.. But what about the gcc_s?
I could theoretically work around the gcc_s issue, but it makes no sense because the crt2.o error won't go away that way.

Clang up until 3.6 invokes gcc when linking is done - -wc-use-mingw-linker is doing the same (but explicitly: wclang -> gcc instead of wclang -> clang -> gcc). Do not compile source files with -wc-use-mingw-linker.

Are you sure wclang is using Clang 3.6...?
It was wrong in my previous statement. It has nothing to do with the distribution. As expected from your previous post it works fine with clang 3.5. I did some more thorough testing and found that without MXE it works flawlessly with Ubuntu Xenial Xerus + Clang 3.8.
I found out that the crt2.o etc files are properly linked when mingw-w64 is installed alongside MXE. I was under the assumption that MXE installed mingw-w64.
When I build MXE and add it to the path I now only get that -lgcc_s cannot be found:

without MXE it works flawlessly with Ubuntu Xenial Xerus + Clang 3.8.
That's what I have fixed.
I found out that the crt2.o etc files are properly linked when mingw-w64 is installed alongside MXE.
That shows how broken Clang's new MinGW driver is... MXE and mingw-w64 are different toolchains (x86_64-w64-mingw32.static != x86_64-w64-mingw32). You shouldn't mix them.
/usr/include/c++
Shouldn't be there either.
I was under the assumption that MXE installed mingw-w64.
MXE has indeed its own CRT objs.
So what do you recommend? I can probably go without MXE for now but what would be the right course of action to get this stuff working? What is actually going wrong that I can report to the llvm folks?
So what do you recommend? I can probably go without MXE for now but what would be the right course of action to get this stuff working?
Either go with Clang <= 3.6 + MXE or with Clang 3.8 + the system's MinGW distribution.
What is actually going wrong that I can report to the llvm folks?
Clang's "new" MinGW driver fails to find the CRT object files and seems to ignore the fact that x86_64-w64-mingw32.static and x86_64-w64-mingw32 are different toolchains.
