In one of my C++ project when I try to compile it on x64, I am getting below error:
x64\Release\command.obj : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'x86'
There are many links, one relvent info looks to me to point Project Properties > VC++ Directories > Executable Directories to only x64 but I see in my project it is also pointing to x86 as well
The current value is "$(VC_ExecutablePath_x64);$(WindowsSDK_ExecutablePath);$(VS_ExecutablePath);$(MSBuild_ExecutablePath);$(FxCopDir);$(PATH);"
But resolved values are as following:
C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.16.27023\bin\HostX86\x64
C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.16.27023\bin\HostX86\x86
C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x86
C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools
C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\tools
C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\ide
C:\Program Files (x86)\HTML Help Workshop
C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Current\Bin
C:\windows\Microsoft.NET\Framework\v4.0.30319\
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
C:\windows\system32
C:\windows
and some more from PATH
I am not able to get from where it is picking first 2 entries i.e. HostX86\x64 and HostX86\x86, how can I remove "HostX86\x86"
In earlier versions, it used to be under Tools > Options
x64\Release\command.obj : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'x86'
The project is NOT building for x64. Rather, the error message referring to "target machine type x86" indicates that it is an x86 build. The command.obj module was created by the 64-bit compiler. So that is the mismatch causing the linker error and I doubt it has anything to do with the default paths for Executable directories.
Have you changed the paths used by the project from the defaults for x86 and x64 builds?
I also suggest that you clean the solutions/projects and do a complete rebuild.
In "Project Properties" for Release x64 configuration "Target Machine" is correctly set to "MachineX64 (/MACHINE:X64)". Where else I need to change the "target machine type"
If you were really building for x64 then the project properties Platform would have the word "Active" as follows -
Without seeing the details of how you have configured the project properties its hard to tell where the mismatch is coming from. The easiest way to diagnose the issue is if you can share the solution/project with us on OneDrive (or equivalent).
One example of mismatched settings -
I have only one platform so no chances of mismatch
thanks YujianYao-MSFT, all were 64 only and build on same computer but this vc project was auto build using cmake. Now as suggested by "RLWA32-6355", I created an empty project and one by one moved all source files and other dependencies to newer project. Now it is working. Although not able to get the root cause of original issue on which I spent whole day. I referred many post including what you shared above but no use.
I suggest you create a new, Empty project. Add the source files from the problematic project to it. Do not make any changes to the Visual Studio defaults for intermediate and target directories. Does it build successfully?
Can you successfully build the console application and the windows desktop applications created by the new project templates?
