WDL-OL - app_wrapper

[antto]

i included all files from the app_wrapper subfolder to my project, and fixed the missing include dirs.. installed the asio sdk, etc..

first i had errors about undefined stuff in app_dialog.cpp
so i added "#include "app_resource.h"" to app_main.h and that seemed to have fixed it

next issue is:

line 304 in app_main.cpp
gPluginInstance->LockMutexAndProcessDoubleReplacing(inputs, outputs, gSigVS);

compiler says that IPlug has no such method

[olilarkin]

are you using the latest wdl-ol? Did you duplicate an example project? That's the best way to do it.

[antto]

can't tell what version it is, i've downloaded it somewhere around july 2013 (that's the date on the zip at least)

and yes, i simply duplicated the IPlugEffect project

[olilarkin]

i recommend you update to the latest version, re-duplicate an example project and bring in the important files such as the main .cpp and .h + resource.h from your old project directory.

I'm surprised the app_wrapper stuff wasn't already set up if you duplicated an example to start with.

[antto]

well, i just updated to the newest version
can't compile the stuff again

now i remember
when i got wdl-ol the first time (months ago) i had loads of compiler errors in the internals, and i modified some files

and now.. (mingw gcc 4.7.2)

i went to try and build the IPlugMouseTest project
same thing happens

[olilarkin]

its set up for msvc on windows and gcc/clang on mac. not enough hours in the day to make it work on gcc on windows

[antto]

i got my sonogram working again
had to change a bunch of things, mostly in IGraphicsWin.cpp

i had to also add _WIN32_IE=0x0300 to the project #defines and add libcommctl32 to the linker

so now.. to see the standalone app stuff
btw: does the standalone version of a plugin use any sound device or is it only via asio?

[antto]

and a side question
on windows, the vst plugin made with IPlug, when active "blocks" the key presses

i am strongly tempted to try and remove that
as an example, most vst plugins i have don't block the key presses and the Host can receive them
it's annoying because i typically use my DAW's virtual keyboard, which stops working when i focus the gui of a plugin made with IPlug

[olilarkin]

asio or directx. If you fork WDL-OL on github i would be interested in merging your gcc fixes

[antto]

i tried the standalone thing again - same error as before, line 304 - no such method in class IPlug

[olilarkin]

ok i think i see the problem

try adding these no-ops to IPlugBase.h

  #ifdef OS_IOS
  void LockMutexAndProcessSingleReplacing(float** inputs, float** outputs, int nFrames) {};
  #else
  void LockMutexAndProcessDoubleReplacing(double** inputs, double** outputs, int nFrames) {};
  #endif

edit - or maybe you didn't define SA_API in your preprocessor defs? (try this first!)

[antto]

i had #defined SA_API ...

now after adding that, the next error is:
..\as_SonoGx2\app_wrapper\app_main.cpp|634|error: too many arguments to function 'IPlugVST* MakePlug()'|

and, on a side note, gcc gives this warning:
app_main.h|30|warning: extra tokens at end of #else directive [enabled by default]|
not that it affects me, just sayin'

Yeah, so this won't help you (sorry!), but:

#else if defined OS_OSX

Should be:

#elif defined OS_OSX

[antto]

fixed those warnings

now, out of boredom, i changed the problematic line to
gPluginInstance = MakePlug();
(i removed the arguments)
...to see how far it'll go next


asiodrvr.cpp, line 16
15 #if WINDOWS
16 #error do not use this
...
21 #else

huehue
i guess i should just forget about this idea
...perhaps savihost

[olilarkin]

I made a new codeblocks project for compiling the standalone app version of IPlugEffect with the latest WDL-OL. Drop it into the IPlugEffect folder

It compiles and runs, but the app doesn't appear and can't be killed from the codeblocks degbugger.

I think perhaps the WinMain() entry point function is not getting called. Got to work on my own projects now, but let me know if you figure it out!

[olilarkin]

I figured out the problem... codeblocks is not preprocessing the .rc file. Didn't work out yet how to make it do that (SA_API needs to be defined so that app_resource.h gets included in resource.h). I hacked it to make it work by copying the contents of app_resource.h into the .rc file

[antto]

in my case, i just added SA_API to the build options and it just worked

however, now with your cbp file, it can't find the asio headers/cpps
i've unzipped the contents of the asio_sdk zip into the \WDL\ASIO_SDK\ folder
and thus they are NOT in the main dir there

more like: \WDL\ASIO_SDK\common\asio.cpp

EDIT: also, RtAudio includes "iasiothiscallresolver.h" which.. i don't even have such file in WDL

[olilarkin]

follow the wdl-ol instructions (readme.txt in WDL-OL/ASIO_SDK) and using my cbp file it should work

[antto]

so, i should have downloaded RtAudio instead of the asio_sdk..
well, it compiles now

however, when i run the IPlugEffect.exe - it doesn't actually open any window or so, no error message, no nothing
the program itself keeps running (i see it in the task manager)

[olilarkin]

I'm not by my windows pc right now, but IIRC i may have also added

  #ifdef __MINGW32__
  extern "C"
  #endif

in front of

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdParam, int nShowCmd)

[antto]

i tried that, no difference
so the app doesn't crash or anything, it even creates a default config.ini file thing, but it just sits hidden in the background and appears to do nothing

[olilarkin]

i've updated the codeblocks projects on the next branch on github

https://github.com/olilarkin/wdl-ol/tree/next

hope that helps

[antto]

i debugged the app build to see what happens
with the debugger i reached the point where it calls CreateDialog() in app_main.cpp but the function returns NULL
then the code goes into the event loop thing, and waits there
i'll try to figure out why it returns null

EDIT: so GetLastError() says ERROR_RESOURCE_TYPE_NOT_FOUND

[olilarkin]

have you tried my latest github version? it works for me

[antto]

i got it working!

for some unknown reason, the #ifdef SA_API in the .rc file was not working, thus all of the dialog stuff in it was not making it thru
i commented-out the #ifdef so that it gets really added
then a few more changes i had to do:
added #include "app_wrapper/app_resource.h"
and had to change the slash char in the icon filepath: "resources/IPlugEffect.ico"

and it works now \o/

[olilarkin]

glad we're finally on the same page. I think it's not possible to run the c preprocessor on the .rc file in codeblocks via windres.exe. http://forums.codeblocks.org/index.php?topic=6835.0

[antto]

and, a tiny question:
i got the FPS set to 60 or so, in the constructor
i then call the sonogram's SetDirty() from the audio process function and it was okayish.. unless the audio buffer is big

i want to redraw the sonogram all the time (60 times per second)
any tips?

[olilarkin]

override the IControl::IsDirty() method and return true
