linking problem: fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86'

Question

Hello, Im trying to run sample app from wxFreeChart library. After compilation on linking there is an error:

wxcode_msw28d_freechart.lib(wxfreechart_lib_xydataset.obj) : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86'

I tried to switch linker option\advanced\target machine to MachineX64 but it doesnt work.

Im using visual studio 2008, any suggestion ?

thanks for help

Answer 1

The error is explicit, you are trying to link libraries that were compiled with different CPU targets. An executable image can only contain pure x86 (32-bit) or pure x64 (64-bit) code. Mixing is not possible.

You change the target CPU by creating a new configuration for the project, only changing the linker setting isn't enough. Build + Configuration Manager, Active solution platform combo on upper right, choose New and select x64. That creates a new configuration with several modified project settings, most importantly the compiler that will be used.

Beware that prior to VS2010, the 64-bit compilers are not installed by default. If you don't see x64 in the platform combo then you'll need to re-run setup.exe and turn on the option to install the 64-bit compilers. Then also re-run any service pack installer you may have applied.

A possible approach with less pain points is to use the 32-bit version of the library.

hi,

i ve same problem. i ve setup all configuration which is mentions in below points but can't find any solution Configuration points are

1. To choose the x64 platform, click Build > Configuration Manager. Under Active Solution Platform, select In the dialog that comes up, select x64 as the new platform (it may come up by default) and then click Ok.
2. select the x64 platform in the VC window.
3. Check the Linker > Command Line property page to make sure there is no /MACHINE switch there 3.1 if you find /MACHINE ** in the additional options window, just deletle it. 3.2. if you find /MACHINE ** in the all options window, go to the Linker > Advanced property page and make sure that Target Machine is "Not Set".

which i get from this link http://software.intel.com/en-us/forums/showthread.php?t=61666

MY Question is that when create 64 platform by select Under Active Solution Platform. A small window opened. there is 2 option in combo BOX 1. empty 2. win32

I wanna mention one thing here that im working on VS C++ 2008 a dll project.i'm working on 64 bit system with 64 bit OS (win 7).

I ve tried both but when i select 2nd one 'win32' then i'll face same problem. Other thing which i ve observed that my project use a .obj file which was create when i run this on win32 OS and system. but now my probject use same .obj file even in x64 OS.

MY first Question :

How can i used new created .obj file which is exist /x64/release folder instead of old one which is exit in /release folder

But when i use 1st one i m facing thes problems
