Hi,

I am trying to run the sample code "blend.cpp" on my computer but I get the following error:
"fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86'"

I would like to use VC++ 2008 to use CPLEX; I have Windows 7 on my computer (I suppose it is 64-bit operation system); I installed IBM ILOG CPLEX V12.1 for Windows 64 bit English (CZ3VCEN); and I select the following settings for my project:

Additional Include Directories:
C:\ILOG\Concert29\include;C:\ILOG\CPLEX121\include

Debug Information Format: Disabled

Additional Dependencies:
C:\ILOG\CPLEX121\lib\x64_windows_vs2008\stat_mta\cplex121.lib
C:\ILOG\CPLEX121\lib\x64_windows_vs2008\stat_mta\ilocplex.lib
C:\ILOG\Concert29\lib\x64_windows_vs2008\stat_mta\concert.lib

Any help to resolve this problem is greatly appreciated!

Thanks,
Reza

The linker error definitely indicates that you have a 32/64-bit mismatch. Your cplex is the 64-bit version, so either your whole Windows 7 is 32-bit version or your VC++ is set up to generate 32-bit objects. My guess is the former.

Laci, thanks for your reply.

I check the system information and system type is "64-bit operating system". So I guess my OS is 64-bit?

But how can I check if the VC++ is set up to generate 32-bit objects?
In the Project Property window I only have Win32 for Platform; do you think that is the problem? Can I change it somehow?
Thanks a lot,
Reza

I had to change the setting of the VS.NET through Control Panel to make it generate 64-bit objects.

Hi,Reza,
I have got same problem. How do you solve this issue. Could you please let me know how do you change the configuration to generate a 64-bit object?

Thank you!

I also meet this problem about one week ago. As this problem is not answered fully, I think it is great to give an answer to this problem as it took me much time on this and got stuck with my research somehow. If you are using a higher version of visual studio, this is not a problem. However for vs2008, it happens.

The problem is that you have build a win32 application on a 64 bit system. What you need to do is to change the release to x64.

1. You need to use your vs2008 installation to install the x64 compilers and tools.

2.“Build” – “Configuration Manager”, for the active solution platform, click and choose new.

3.choose x64 in the pop up window.

Then you can successfully run the program~
