Subject	[Cs-dev] Holdup on Windows installers
	I've run into a serious roadblock on preparing the Csound 5.12 windows installer. The module loading and module unloading code causes segmentation violations with some libraries including tclcsound.dll and rtpa.dll. This in turn causes Csound not to be re-startable. And that means QuteCsound and other hosts do not work. The problem appears to be exhibited in this stack trace and seems to have something to do with thread local storage in MinGW. I am using the Twilight Dragon Media build of MinGW but I will try the regular build of MinGW now. #0 ??

	What suprises me is that rtpa wants to call code from fltk.

	I'm pretty sure there is an interaction with FLTK. In GCC and MinGW and TDM MinGW, the code for handling exceptions across image boundaries in multi-threaded code has been in flux for two years. I'm beginning to wonder why it ever worked. I'm going to revert the compiler and see if that helps. Unloading libraries has also been an issue, I may just omit that step on Windows and see what happens. Note that at this point I am building FLTK itself, PortAudio, and Csound with the same options for threading and exception handling. The same exception happens in tclcsound.dll and in rtpa.dll even if all plugins and modules that link with FLTK are removed from the path (though I hope I didn't miss anyway).

	In the development environment all shared libraries in the Csound directory are loaded and interrogated for module entry points. Then they are unloaded. All modules that are loaded for use also are unloaded (FreeLibrary on Windows, problematic) at the end of the CSound run.

	No. There is still the same problem. Moving the DLLs proves it's not only a tclcsound or an FLTK problem. It still happens with just rpa.dll.

	The 3 plugins that are problematic for QuteCsound are virtual.dll, widgets.dll, and fluidOpcodes.dll, although I'm not sure fluidOpcodes.dll does anything with fltk.

	rtpa.c has indeed not changed. I will try reverting PortAudio. I have not yet tried reverting the compiler. I have excluded FLTK as a cause of this problem. It happens when FreeLibrary is called on the rtpa DLL handle. I can also try linking the PortAudio library statically.

Subject	Re: [Cs-dev] Holdup on Windows installers
	I solved the problem. The cause is that PortAudio contains C++ code, but the rtpa module was being compiled as C code, lacking the MinGW libraries required to handle exceptions that are thrown from multi-threaded code in DLLs. The result was that when the PortAudio module was unloaded, there was a segmentation fault. I fixed the problem by creating a shim rtpa.cpp file that #includes rtpa.c, and modifying SConstruct so that for MinGW, rtpa.cpp is compiled and linked instead of rtpa.c. There is no longer a segmentation fault when the rtpa module is unloaded, and Csound can be stopped and restarted in QuteCsound.

	Shouldn't this be solved on the portaudio side? I cannot imagine why calling a C library that happens to have some implementation details in C++ from a C source file should cause trouble.

Subject	Re: [Cs-dev] Holdup on Windows installers
	It does cause trouble, and it is not (only) a PortAudio problem. It is indeed (also) a Csound problem. The behavior of the MinGW compiler for handling exceptions in shared libraries has changed and caused this problem for our code. The underlying problem is that C++ code can throw exceptions, but C code cannot. With the new MinGW compiler, exception handling for C++ is not done in the runtime library any more, but in a supplementary shared library. This library is not linked into C executables, only into C++ executables. Perhaps the old compiler just ignored these exceptions, or perhaps they were handled properly from the runtime library, but in any case, in the new compiler they cause a segfault unless the exception handling library is linked in by compiling and linking rtpa as C++ code.

	Well done. Michael, this must have been a tricky one to diagnose. Maybe a note can be dropped to the portaudio list just warning about this possible behaviour in C programs (after all portaudio has a C API and it's likely that people will call it from C code).

Subject	Re: [Cs-dev] Holdup on Windows installers
	It was tricky and we are not out of the woods yet. First, there is a problem with FLTK, this DLL exception problem is in addition to the FLTK problem although the FLTK problem may be another form of the DLL exception problem. And this affects CsoundVST, vst4cs, the FLTK widgets, the virtual keyboard, and the Fluid opcodes. Second, I can indeed start and stop performances now in QuteCsound which I could not do before, but I still cannot let a performance run out. It hangs at the end. I think I probably need to build QuteCsound itself with the relevant options. I am working on that now. I'm pretty sure this means that the current Windows build of QuteCsound will never work with the upcoming release of Csound 5.12. I'm still thinking about reverting the compiler, but the current TDM compiler is up to date and easy to install, so as long as I seem to be making progress I will persist.

	There is still a problem with FLTK. Repeat: there have been two problems, one with PortAudio and one with FLTK. The PortAudio problem is solved but the FLTK problem remains. I configured FLTK to build with the correct options but I need to make sure they are actually being used. On Wed, Sep 1, 2010 at 12:47 PM, andy fillebrown wrote: > Sweet!

	I got past some of the FLTK problems by ensuring correct link options, but I still can't finish a performance and then restart in QuteCsound. Also, there are problems with Python and, I expect, other stuff. So, there are enough problems with the new compiler and getting executables to work together than I am going to try reverting the compiler now.

From	Michael Gogins
Subject	Re: [Cs-dev] Holdup on Windows installers
	The problem appears to have been completely resolved by simply compiling everything -- Csound, third-party dependencies that build with MinGW, and QuteCsound -- with the version of MinGW that installs with Qt. This is gcc version 4.4.0 from Qt/MinGW, whereas the version I was using before was gcc version 4.5.0 from Twilight Dragon Media. I had chosen TDM because it was easy to install and had more up to date OpenMP support, but obviously there are problems. The current Qt/MinGW compiler uses dw2 exception handling, whereas the TDM compiler uses setjump-longjump exception handling. If no further major problems turn up, I should be able to upload the Windows installer before this weekend.

Subject	Re: [Cs-dev] Holdup on Windows installers
	Hi Michael, Would the current QuteCsound packages be incompatible with this release? Would we need to do anything different when building QuteCsound on Windows from now on?

Subject	Re: [Cs-dev] Holdup on Windows installers
	The current QuteCsound releases should be OK since I have switched to building Csound with the exact same compiler used by the complete Qt installation. You should not have to make any changes to your code or build system. I did find one bug that prevented Csound from working properly in QuteCsound, but that bug was caused by QuteCsound resetting the Csound message callback to null. That in turn caused a segment fault when QuteCsound destroys Csound and Csound tries to print messages as it takes itself apart. Rather than monkey with QuteCsound code, I changed csound.c to reset to the default message callback when someone tries to set the message callback to null. There are other possible solutions, but that seems OK for now. At any rate, I am much relieved, and I suspect you may be as well.

Subject	Re: [Cs-dev] Holdup on Windows installers
	Hi, Thanks Michael. I think I did that because under certain circumstances QuteCsound was receiving messages from Csound after the Csound thread had joined, which caused problems for example if a tab had been closed and it's associated data was no longer available. Not sure if that change actually fixed it, but thanks for fixing it on the Csound side. Good to know I don't have extra work... =) Cheers, Andrés On Thu, Sep 2, 2010 at 5:27 PM, Michael Gogins wrote: > The current QuteCsound releases should be OK since I have switched to > building Csound with the exact same compiler used by the complete Qt > installation. > > You should not have to make any changes to your code or build system. > > I did find one bug that prevented Csound from working properly in > QuteCsound, but that bug was caused by QuteCsound resetting the Csound > message callback to null.

Subject	Re: [Cs-dev] Holdup on Windows installers
	I don't think your change really did fix it. We will see if mine did. If not we can change the Csound code to print no messages if the callback is null. That is more work and slightly less efficient and may not be best in all cases but should certainly work in this case.

Subject	Re: [Cs-dev] Holdup on Windows installers
	It will be great to have Csound for the weekend so I can experiment the floating version whit Cecilia4 on Windows since Cecilia4 run perfectly with Csound 5.12.4 on Mac. Thanks for your work, Marc -----Message d'origine----- De : Michael Gogins [mailto:michael.gogins@gmail.com] Envoyé : 2 septembre 2010 11:43 À : Developer discussions Objet : Re: [Cs-dev] Holdup on Windows installers The problem appears to have been completely resolved by simply compiling everything -- Csound, third-party dependencies that build with MinGW, and QuteCsound -- with the version of MinGW that installs with Qt. This is gcc version 4.4.0 from Qt/MinGW, whereas the version I was using before was gcc version 4.5.0 from Twilight Dragon Media. I had chosen TDM because it was easy to install and had more up to date OpenMP support, but obviously there are problems. The current Qt/MinGW compiler uses dw2 exception handling, whereas the TDM compiler uses setjump-longjump exception handling. If no further major problems turn up, I should be able to upload the Windows installer before this weekend.

	Nice, Cecilia4 uses crossfm opcodes added in Csound 5.12! Olivier 2010/9/2 Caecos <mddemers@hotmail.com> It will be great to have Csound for the weekend so I can experiment the floating version whit Cecilia4 on Windows since Cecilia4 run perfectly with Csound 5.12.4 on Mac. Thanks for your work, Marc -----Message d'origine----- De : Michael Gogins [mailto:michael.gogins@gmail.com] Envoyé : 2 septembre 2010 11:43 À : Developer discussions Objet : Re: [Cs-dev] Holdup on Windows installers The problem appears to have been completely resolved by simply compiling everything -- Csound, third-party dependencies that build with MinGW, and QuteCsound -- with the version of MinGW that installs with Qt. This is gcc version 4.4.0 from Qt/MinGW, whereas the version I was using before was gcc version 4.5.0 from Twilight Dragon Media. I had chosen TDM because it was easy to install and had more up to date OpenMP support, but obviously there are problems. The current Qt/MinGW compiler uses dw2 exception handling, whereas the TDM compiler uses setjump-longjump exception handling. If no further major problems turn up, I should be able to upload the Windows installer before this weekend.

	Cecilia4 (source version) is working fine with Csound 5.12.1-d. Only the module windows does not always display correctly. Marc Date: Thu, 2 Sep 2010 20:41:00 -0400 From: olivier.belanger@umontreal.ca To: csound-devel@lists.sourceforge.net Subject: Re: [Cs-dev] Holdup on Windows installers Nice, Cecilia4 uses crossfm opcodes added in Csound 5.12! Olivier 2010/9/2 Caecos <mddemers@hotmail.com> It will be great to have Csound for the weekend so I can experiment the floating version whit Cecilia4 on Windows since Cecilia4 run perfectly with Csound 5.12.4 on Mac. Thanks for your work, Marc -----Message d'origine----- De : Michael Gogins [mailto:michael.gogins@gmail.com] Envoyé : 2 septembre 2010 11:43 À : Developer discussions Objet : Re: [Cs-dev] Holdup on Windows installers The problem appears to have been completely resolved by simply compiling everything -- Csound, third-party dependencies that build with MinGW, and QuteCsound -- with the version of MinGW that installs with Qt. This is gcc version 4.4.0 from Qt/MinGW, whereas the version I was using before was gcc version 4.5.0 from Twilight Dragon Media. I had chosen TDM because it was easy to install and had more up to date OpenMP support, but obviously there are problems. The current Qt/MinGW compiler uses dw2 exception handling, whereas the TDM compiler uses setjump-longjump exception handling. If no further major problems turn up, I should be able to upload the Windows installer before this weekend.
