Hi all,

I have installed CPLEX 12.4 (64 bits) on my computer running Windows 7 (64 bits). But I am unable to link CPLEX with Visual Studio 2008. I have followed the instructions given in the c_cpp.html file inside the "cplex" folder. Instead of using the instruction:

Select Linker in the Configuration Properties tree.
Select General and then select Additional Library Directoriess. Add the files:
<CPLEXDIR>\lib\x86_windows_vs2008\stat_mta
<CONCERTDIR>\lib\x86_windows_vs2008\stat_mta

I have used:

Select Linker in the Configuration Properties tree.
Select General and then select Additional Library Directoriess. Add the files:
<CPLEXDIR>\lib\x64_windows_vs2008\stat_mta
<CONCERTDIR>\lib\x64_windows_vs2008\stat_mta

Rest of the instruction I have followed exactly.

When I build the project, I get the errors like "LNK2001: unresolved external symbol_imp_CPXopenCPLEX@4 "

Actually, I want to use 64 bit CPLEX because I am solving very large linear and integer programs (with approx 300,000 binary variables and 5000 constraints). If I use the original setting, the project build is successful but I am unable to solve the linear and integer programs. There is CPLEX out of memory error.

Please help me. I will be grateful.

Thanks
Faiz

Is your project configured for 64bit? The "solution platform" should be something like "x64". If it is not, try

• Project->Properties and click the "Configuration manager" button.
• Select "<New ...>" from the "Active Solution Platform" pulldown.
• Select x64 from the list of platforms.
• Set the x64 platform for your project, set all the variables as before (as described in c_cpp.html).
• Try again.

Thanks for your advise.

I did what you suggested but now get the following message:
1>------ Skipped Build: Project: TEST2, Configuration: Release Win32

---

1>Project not selected to build for this solution configuration
========== Build: 0 succeeded or up-to-date, 0 failed, 1 skipped ==========

What should I do?
Thanks.
