Thanks. I think I have this working now. I have been using consistent objs (MT|MD|CRT vers) and build everything from src.
The trick is to use a seed ocaml compiler (without flex).


1.       FlexDLL version 0.19 does not work with visual studio 12. The latest version 034 is ok.

2.       Avoid compiling FlexDLL with an ocaml compiler that is built with an older version of flexdll (hence the use of a seed compiler)

Regards

Are you using flexdll.obj and flexdll_initer.obj compiled using VS 2012 yourself from sources, or ones the FlexDLL binary distribution (which are not compiled with VS 2012)?

I did a lot of testing earlier this year in advance of 4.03 running the testsuite with every single version of Visual Studio (I went right back to Visual Studio 6), but I was always compiling the object files freshly for each compiler. Although I wasn’t building findlib, it would surprise me hugely that the testsuite would pass yet this systemically not work.

I’ve not used it, but I know that ocp-win includes the object files compiled for each version of Visual Studio, which is why Fabrice recommended it.
