Problem compiling hello world on Windows

[Altera_Forum]

I am attempting to compile and run the hello world design example using the emulator on Windows 7 with Visual Studio 2013. I have AOCL and Quartus installed and the environment configured according to the quick start guide. 

 The host application compiles successfully using Visual Studio but when I run the executable, a message appears that says "The program can't start because altera_s5_ref_mmd.dll is missing from your computer. Try reinstalling the program to fix this problem." There is a file named altera_s5_ref_mmd.lib located in %ALTERAOCLSDKROOT%\board\s5_ref\windows64\lib but I do not see a dll. I also see the same error when I run aocl diagnose.  Additionally, I am not able to compile the kernel. When I run "aoc -march=emulator -v device/hello_world.cl", this is the output:   aoc: Environment checks are completed successfully. You are now compiling the full flow!! aoc: Selected target board s5_ref aoc: Running OpenCL parser.... aoc: OpenCL parser completed successfully. aoc: Compiling for Emulation .... Error: Optimizer FAILED. Refer hello_world/hello_world.log for details.   Here is the contents of hello_world.log:   Microsoft (R) Incremental Linker Version 12.00.21005.1 Copyright (C) Microsoft Corporation.

Hi, 

after days of struggling with very same problems I've finally solved both of them. First of all I'd like to address a problem with emulation. You have to set LIB variable to "(...)\Microsoft Visual Studio 10.0\VC\lib\amd64" ("amd64" is essential). However, after adding it you'd probably get an error regarding the "kernel32.lib" file. Thus you have to add additional path to LIB variable. "Kernel32.lib" file is located in "X:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64" directory and this is the directory you have to add to LIB variable. I have to mention that I was using VS2010 Professional with SP1, yet, VS2013 should probably do fine as well (as long as you add proper paths to LIB variable).  The altera_s5_ref_mmd.lib file is located in X:\altera\14.0\hld\board\(YOUR_BOARD)\windows64\bin, so make sure you add this directory to the PATH variable. You run "aocl install" afterwards and hopefully "aocl diagnose" won't return any errors. Then, again, after compiling successfully with "-march=emulator" flag, you shouldn't be surprised to have another error after host program execution (obviously, after building it with VS). This time it should be the "wdapi1021.dll" file. I just copied it form X:\altera\14.0\hld\board\s5_ref\windows64\driver directory to X:\Windows\System32.  After all these steps I successfully managed to run emulation. I may have forgotten about something and if so, please post an error you got and I may recall a solution to it.

I had the same linker errors and chris.lark's answer didn't solve it for me. What worked for me is: 1) Do NOT manually add the link.exe location to the PATH environment variable 2) call the altera/15.1/hld/init_opencl.bat file which sets up the environment. The init script checks if link.exe is found and if it is, it assumes that the visual studio environment has been set up correctly. Only if link.exe is not found, it will "guess" the visual studio installation (looking for VS10, VS11, VS12 in that order) and then call the visual studio script vcvars64.bat which (supposedly) sets some env variables to point to the right places. (Alternatively, you can of course put the link.exe in PATH and call the vcvars64.bat manually, instead of the init_opencl.bat, to keep the guesswork out of the build step).

This path environment really giving alot of issues.

Thanks a lot, Chris! I could build the aocx file after following your steps, but wanted to post a couple of observations.

Hi, 

 are you still facing the issue? Please copy the output from aocl install here. Then we can go from there.

[Altera_Forum]

Yes, I think it's because I don't have the board support package for cyclone V GT, and writing one is seems like a huge challenge. 

 A problem I am more concern about is: https://stackoverflow.com/questions/44211574/compiling-opencl-code-using-altera-aoc-unresolved-external-symbol

[Altera_Forum]

So yes, if there is no BSP (Board Support Package) and therefore no driver you cannot install the board and you will see errors if you are trying to do so. 

 The problem shown in that link is related to your Visual Studio Version? Which one are you using? If you are using Microsoft Visual Studio 15 or higher take a look here to resolve it: https://stackoverflow.com/questions/31242820/visual-studio-14-0-lnk2001-unresolved-external-symbol-with-opencl  Cheers, fade

I have the same problem but the message is a little bit different: 

 aoc: Environment checks are completed successfully. You are now compiling the full flow!! aoc: Selected target board a10gx aoc: Running OpenCL parser.... aoc: OpenCL parser completed successfully. aoc: Compiling for Emulation .... Error: Linker FAILED. Refer hello_world/hello_world.log for details.  I try everything to fix the linker problem but I don´t find solution. I´m using Quartus Primer Pro 17.0, windows 10 and Visual Studio Community 2017. Can somebody help me please?

I am also having issues with running hello_world. My issue is I can use VS2010 to build host.exe and aol to build the hello_world.aocx but when I run host.exe, get the error
