Compile bug.

[Alex-Longard]

Hello Andrew, If I try to compile with cmd, shows this error:

C:\msys64\VST>make process_begin: CreateProcess(NULL, cc -dumpmachine, ...) failed. make: Makefile:15: pipe: No error process_begin: CreateProcess(NULL, cc -dumpmachine, ...) failed. make: Makefile:17: pipe: No error process_begin: CreateProcess(NULL, cc -dumpmachine, ...) failed. make: Makefile:19: pipe: No error Makefile:22: *** Could not determine architecture. Stop.

I compile in Win10 x64, Mingw64 last version. Do you can write example .bat file for compile HelloVST with windows console?

[AndrewBelt]

Could you post the results of gcc -dumpmachine?

[Alex-Longard]

There dump: C:\msys64\VST>C:\mingw32\bin\gcc.exe -dumpmachine i686-w64-mingw32

Thanks for help!

[AndrewBelt]

Are you using the MSYS2 Mingw64 shell as specified at https://github.com/AndrewBelt/HelloDAW/tree/master/VST#windows or the Windows shell (cmd.exe or Powershell)?

[Alex-Longard]

I compile with Windows command line - cmd.exe, i not use powershell.

[AndrewBelt]

I'm not sure that will work. You'll have to use MSYS2. If you can't or don't want to use MSYS2 for whatever reason, it might be possible, but I personally don't have a reason to try to support that.

[Alex-Longard]

I do not know how to use Msys. I installed it only today for Hellovst. I want to write a vst plugin for my task, since plug-in developers do not want to cooperate with blind users, and few of the blind program for audio software.

[AndrewBelt]

I am not sure if MSYS2 is blind accessible, but it is a text-based terminal interface like cmd.exe, so you might have luck with it. The shells are at C:\msys64\mingw64.exe and mingw32.exe, depending on whether you want to compile a 64-bit or 32-bit VST plugin. If this doesn't work, I'll see if it's easy to add support for cmd.exe.

[Alex-Longard]

Msys shell accessible for screenreader, only this not work. I write in msys terminal: cd .\vst make

And this shows result, as i write in first message.

[AndrewBelt]

I am not sure, I can't replicate this. What is the output of which make?

[Alex-Longard]

O, i can try to compile this in msys, it's shows more bugs in one file:

It's output log:

[AndrewBelt]

Thanks, I forgot the stdint.h header. Do a git pull and try it now.

[Alex-Longard]

Hmmm, many varnings and new bug:

C:\msys64\VST>make g++ -std=c++11 -g -MMD -MP -O3 -march=nocona -ffast-math -Wall -Wextra -Wno-unused-parameter -fPIC -IVST2_SDK -c -o build/HelloVST.cpp.o HelloVST.cpp HelloVST.cpp:22:15: warning: multi-character character constant [-Wmultichar] setUniqueID('HELO'); ^~ HelloVST.cpp: In member function 'virtual void HelloVST::getParameterLabel(VstInt32, char*)': HelloVST.cpp:51:41: warning: zero-length ms_printf format string [-Wformat-zero-length] snprintf(label, kVstMaxParamStrLen, ""); ^ HelloVST.cpp:51:41: warning: zero-length ms_printf format string [-Wformat-zero-length] make: *** No rule to make target 'build/VST2_SDK/public.sdk/source/vst2.x/audioeffect.cpp.o', needed by 'HelloVST.dll'. Stop.

[AndrewBelt]

You can ignore the warnings, they're fine. Did you copy the VST2_SDK directory from Steinberg's VST SDK to HelloDAW's VST directory?

[Alex-Longard]

Yes, copy folder and change path in hellovst for audioefectx.h. This write new error:

Makefile:104: recipe for target 'build/VST2_SDK/public.sdk/source/vst2.x/audioeffect.cpp.o' failed make: *** [build/VST2_SDK/public.sdk/source/vst2.x/audioeffect.cpp.o] Error 1

[Alex-Longard]

Andrew, i will can start Team viewer and you can see in my system.

[AndrewBelt]

I don't have time tonight to look at your system, but make sure that the file <HelloDAW root>/VST/VST2_SDK/public.sdk/source/vst2.x/audioeffect.cpp is present, since that's what the error is complaining about.

[Alex-Longard]

In terminal shows: error in command syntax Makefile:104: recipe for target 'build/VST2_SDK/public.sdk/source/vst2.x/audioeffect.cpp.o' failed

In this string audioefect.cpp.o, it's bug in makefile? My files and folders normal, i try this now.
