Failing to build jnlua for win64
Michi
I want to build jnlua for my 64 bit windows 7. I know there are precompiled versions, but I want to know how to do it myself :)
I downloaded http://sourceforge.net/projects/luabinaries/files/5.2/Windows%20Libraries/Dynamic/lua-5.2_Win64_dll10_lib.zip/download and unpacked it, and let the makefile point to that directory. Then I run my VC 10 Express Console and type nmake. This is what I get:
...\jnlua-1.0.2\src\main\c\Win32>nmake

Stop.
Can you give me a hint why this is not working as expected?
Thanks!

Are you explicitly launching the 64 bit console? The default start menu entry of VC is for the 32 bit console, even when running on a 64 bit system. To check, change out of the console launch directory (as the cl.exe found there is 32 bit at all times), and then launch cl.exe from the configured path.
OK output: Microsoft (R) C/C++ Optimizing Compiler Version 15.00.30729.01 for x64
NOT OK: Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 15.00.30729.01 for 80x86

You are right, the 32 bit version is being used. But I still get the same linker errors when trying to build the 32 bit version. I think I am missing something else.. :(

Try running dumpbin /all on your lua52.lib file, and pay specific attention to the number of underscores following __imp. Building a 32 bit version against a 64 bit DLL/LIB will not work, of course.

Thanks for the quick response!
