I am running a 64 Bit Windows 7 Pro machine. I use Intel Parallel Studio XE 2011 (x86) with MS Visual Studio 2008. I have never used TRNSYS or IPS on anything other than 64 Bit machines (I am still relatively new). I have not changed any settings in the compiler, and installed with recommended settings. I do not do execute any compiling commands from within TRNSYS, I have found it easy enough to compile within IPS, make a copy of the .dll in the project folder and paste it into the release dll's folder. I do not think you need to make any changes. The only bug I have is that every now and then I get an error with TypeCK, it will say something like value a exceeds value c, and compiling aborted. When this happens I close IPS, open it again, clean the solution, then it compiles. This was a pain before I found out it could be easily remedied. -Aaron From: Hauer, Martin [mailto:Martin.Hauer@uibk.ac.at] Hello, Again I have to fight with some compiler problems...maybe someone has a solution for this. Im using the Fortran Compiler 12.0 with MS VS 2010 I had to change from 32bit to a 64bit system – therefore I still copied my already existing personal Type-Codes from the old Compiler folder to the new machines compiler folder in TRNSYS. But now I get a list of errors concerning the internal TRNSYS- functions – although Im using exactly the same compiler settings than in my win32-version. (see attached file!) Looks like, that he can’t find the TRNSYS-definitions, maybe there exists a linking problem to the TRNDll..? Does anybody run his compiler on 64-bit. Is it necessary to do changes in the comiler settings (from Win32 to x64 for each project?,..) I also read, that there could be problems with the different programm folders on win64 (programm files and programm files (x86)).. Thanks for helps! Martin |
