[cfe-dev] i686-pc-mingw32-g++.exe: error: unrecognized command line option '-Weverything'

[Mailing List Email]

Hi all,

I am building clang from the latest svn.
I've successfully managed to build clang, but I cannot compile a simple
program.
So I built clang with mingw (x86) based on gcc 4.8.0 and copied the
executables to the mingw bin directory.

This is the command line I use to build a simple program:

clang++
-isystem"D:\Dropbox\Stuff\Projects\llvm\build\lib\clang\3.4\include"
-isystem"C:\test\mingw32-4.8.0-x86\i686-pc-mingw32\include"
-isystem"C:\test\mingw32-4.8.0-x86\include\c++\4.8.0"
-isystem"C:\test\mingw32-4.8.0-x86\include\c++\4.8.0\i686-pc-mingw32"
-isystem"C:\Program Files\Gecode\include"
-L"D:\Dropbox\Stuff\Projects\gecode-4.0.0\build_clang" -Weverything
-std=c++11 -Wno-c++98-compat -Wno-c++98-compat-pedantic
-Wno-exit-time-destructors -Wno-global-constructors Temp.cpp

When I compile the source, I get this:

clang++.exe: error: assembler (via gcc) command failed with exit code 1
(use -v to see invocation)

What is the problem here? Is clang incorrectly configured or is this
version of g++ just incompatible with clang++?

To make clang, I simply use:

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release ..
start /low /affinity 7f /b ninja

(Using mingw based on gcc 4.8.0.)
