[Linuxsampler-devel] Warnings when compiling linuxsampler with GCC 15.1.0

[Philippe D. <phi...@la...>]

Hi

We are compiling Linuxsampler with GCC 15.1.0

It compiles well but we get several warnings about :

[-Wdeprecated-declarations]

[-Winconsistent-missing-override]

[-Wimplicit-const-int-float-conversion]

[-Wnull-dereference]

[-Wunused-result]

[-Wnan-infinity-disabled]

[-Wtautological-constant-out-of-range-compare]


And in the end some tags for Doxyfile have become obsolete


As said before that doesn't prevent to compile but that will need 
corrections in the future

I attach an extract of the build.log to locate the parts of code to modify

Hoping this will help

Best Regards (and many thanks for your work)

Both of them allow to compile for armv7hl on our BuildSystem
Nevertheless I choosed to apply the first one with
return t   and not      return lo
for coherency with the other arches


I'm gonna test to compile with

asm volatile ("mrc p15, 0, %0, c9, c13, 0" : "=r" (t));


Unfortunately we can't test the use on a real armv7hl system (using a 
virtual system is not enough)

Yeah, looks like that's an ARMv8 (a.k.a. ARM64) feature.

Would be good to know not only if it compiles, but whether it works at 
runtime. Because as you can see from the warning, special privileges or 
preceding system configuration steps might be required for this to work at 
all.

If not, it's getting pretty ugly for the user. Since the sampler would first 
start without complaint and eventually after loading a sound the app would die 
with illegal instruction exception.

[Linuxsampler-devel] problem to build linuxsampler 2.4.0 for armv7hl

[Philippe D. <phi...@la...>]

Hi

We use to create rpms of gig linuxsampler gigedit and qsampler for i686 
, x86_64 , aarch64  and  armv7hl...

There's something wrong when we try to build linuxsampler 2.4.0 for 
armv7hl :

This concerns RTMath.cpp ... We get a build failure with this message :

RTMath.cpp:79:19: error: invalid operand for instruction
     79 |     asm volatile ("mrs %0, cntvct_el0" : "=r"(t));


This is linked to the instructions from line 77 to 80 #elif 
defined(__ARM_ARCH_7A__) || defined(__ARM_ARCH_7S__) uint32_t t; asm 
volatile ("mrs %0, cntvct_el0" : "=r"(t)); return t;

Maybe we should use for ARM_ARCH_75
the same instruction as for ARMv6 ... that is :
     uint32_t t;
     asm volatile ("mrc p15, 0, %0, c15, c12, 1" : "=r" (t));
     return t;

Thanks for your work
and for your help

Hmm, after reading the Qt documentation on this, I realized the purpose of 
windeployqt / macdeployqt is something else. I thought it was a Qt installer. 
It is not. It is run against a compiled Qt application binary (e.g. 
qsampler.exe) and it would modify the executable (replacing absolute DLL paths 
by relative ones) and adds all required Qt libraries to the directory of the 
executable so that the Qt executable would run *without* installing Qt.

I am not sure where you got that CMake block from, apparently this block is 
just run if CONFIG_INSTALL_QT was explicitly set by the user from the command 
line?

I would leave it there for now. It might be useful in future when we change 
the entire installation packages to work with pure app bundles (i.e. to allow 
installing without admin permissions in future and avoiding DLL version 
conflicts).

Yeah, I think it's OK. Thanks Rui!

For the Windows target cmake now correctly installs qsampler.exe:

  + cmake --install build --verbose
  -- Install configuration: "Release"
  -- Installing: /home/persson/win32/bin/qsampler.exe
  -- Up-to-date: /home/persson/win32/share/qsampler/translations/qsampler_cs.qm
  -- Up-to-date: /home/persson/win32/share/qsampler/translations/qsampler_fr.qm
  -- Up-to-date: /home/persson/win32/share/qsampler/translations/qsampler_ru.qm

And for the Mac target it installs the qsampler app bundle:

  + cmake --install build --prefix /home/persson/mac64/ --verbose
  -- Install configuration: "Release"
  -- Up-to-date: /home/persson/mac64/bin/qsampler.app
  -- Up-to-date: /home/persson/mac64/bin/qsampler.app/Contents
  -- Up-to-date: /home/persson/mac64/bin/qsampler.app/Contents/Resources
  -- Up-to-date: /home/persson/mac64/bin/qsampler.app/Contents/Resources/qsampler.icns
  -- Up-to-date: /home/persson/mac64/bin/qsampler.app/Contents/Info.plist
  -- Up-to-date: /home/persson/mac64/bin/qsampler.app/Contents/MacOS
  -- Up-to-date: /home/persson/mac64/bin/qsampler.app/Contents/MacOS/qsampler
  -- Installing: /home/persson/mac64/share/qsampler/translations/qsampler_cs.qm
  -- Installing: /home/persson/mac64/share/qsampler/translations/qsampler_fr.qm
  -- Installing: /home/persson/mac64/share/qsampler/translations/qsampler_ru.qm

I saw that you also added an optional installation of Qt onto the system.
While that probably makes sense for Windows, on a Mac the common way is to
just include the required Qt libraries (as "frameworks") with qsampler's app
bundle (i.e. inside that "qsampler.app" directory).

however these have been "blindly" pasted from elsewhere and there are no

The install prefix controls *where* cmake installs to. We already had the
prefix set and cmake picks up the requested install prefix correctly (both via
CMAKE_INSTALL_PREFIX variable, as well as via --prefix option, doesn't
matter).

The problem rather is *what* cmake installs. For the QSampler Mac build cmake
does not install any file at all:

  + cmake --install build --prefix /home/persson/mac64/ --verbose
  -- Install configuration: "Release"

For the QSampler Windows build cmake only installs the translation files, but
not the most relevant file qsampler.exe:

  + cmake --install build --verbose
  -- Install configuration: "Release"
  -- Up-to-date: /home/persson/win32/share/qsampler/translations/qsampler_cs.qm
  -- Up-to-date: /home/persson/win32/share/qsampler/translations/qsampler_fr.qm
  -- Up-to-date: /home/persson/win32/share/qsampler/translations/qsampler_ru.qm

Like described in my previous email, cmake --install looks into the file
./build/install_manifest.txt to determine what to install. In case of the
Windows build that file only contains those 3 translation files, and in case
of the Mac build that file is completely empty.

Yes I do, use the following spell:

# configure:
cmake -DCMAKE_INSTALL_PREFIX=$PREFIX -B build

# build:
cmake --build build

# install: much like for make DESTDIR env var might be handy here: \
cmake --install build

You can try with latest Fantasia version. It doesn't require installed Java

OK, I checked with strace what cmake --install actually does: it does not
install anything. It looks into a file ./build/install_manifest.txt, which is
completely empty, then it stops.

No idea why cmake generates an empty install_manifest.txt file. I just
manually wrote some install shell commands for QSampler instead.

I replaced the stable Mac installer link with the corrected Mac installer on
the website.

If I find some time I'll probably send a patch for cmake. Because honestly,
now matter why that file is empty, IMO cmake should error out when a user
tries "cmake --install" and cmake not installing anything.

Mja, confirmed. The Mac installer actually ships an ancient version of
QSampler and liblscp. This issue exists since the transition of liblscp/
QSampler from autoconf to CMake.

I guess the same applies to the Windows installer.

The thing is, the binaries are automatically built on our server. Once they
are (re)built, they have to be installed into a specific directory on our
server for the Mac/Win installer scripts to grab them up.

The problem I have is, I don't see an obvious way how to output where cmake is
installing to, or how exactly. I tried the only documented way which is

	cmake --install build --verbose

But that does not output anything more than without --verbose.

Rui, you don't have a clue either, right?

BTW the auto built binaries look fine. QSampler is correctly linked to latest
libgig etc. So it is really just the cmake --install step on server that's
flawed.

[Linuxsampler-devel] 2.4.0 and 2.3.1 Releases not working on MacOS

[TJ L. <tjl...@ma...>]

Has anyone tested Linuxsampler with a recent version of MacOS? I cannot get LinuxSampler working at all. Obviously, it’s not apple silicon but there are several issues preventing LinuxSampler from working it seems.

- When loading the VST plugin, it is trying to open Fantasia as it does on Windows. However, Fantasia is using a very old version of Java that cannot run in MacOS so Fantasia cannot open. There used to be a workaround to use an older version of JavaApplicationStub, however the version used for Fantasia seems to be deprecated on recent versions of MacOS.



- The AU plugin does not load at all. This includes versions previous to 2.4.0 as well as the most recent 2.4.0 release.



- Both the VST and AU plugins do not scan correctly in several hosts. For example, the VST scans correctly in Reaper but not the AU. In Plogue Bidule, neither the VST or AU scan. In MainStage/Logic (AU support only) the AU does not scan.

- QSampler requires libgig.10.dylib even though libgig.11.dylib was installed for previous versions (2.3.1)  and libgig.12.dylib for the most recent version (2.4.0). So in order to open QSampler, you have to symlink the libgig file and rename it to libgig.10.dylib.



- Even when symlinking to the the old libgig dylib and QSampler opens and the server starts, it does not seem to be able to communicate with the VST plugin at all. The AU plugin does not load on any tested DAW/Host so I cannot test QSampler with the AU. Also, versions previous to 2.4.0 I could at least load an instrument in QSampler even though it could not communicate with the plugin. However, with the latest 2.4.0 version, loading any GIG library crashes QSampler instantly. Obviously, Fantasia would be the better choice but without updated support for newer versions of Java that does not seem possible at the moment.

This is tested on MacOS Sequoia 15.5 on a Mac Mini M4 Pro. I’ve used LinuxSampler quite a bit on both Windows and Linux. I used to use it on Mac pretty extensively in the OSX days before MacOS but not since.

If anyone could take a look it would be much appreciated. Again, this is not an apple silicon compatibility issue. I’m running a few other MacOS intel plugins in Rosetta without issue. Prior to these latest tests, I manually uninstalled all the Linuxsampler package files and then had pgkutil forget the packages before reinstalling the latest version. Please let me know if I can provide any further information.

Much thanks,

TJ Lindgren

[Linuxsampler-devel] LinuxSampler as a plugin - enabling more than 16 channels

[Gastón T. <tay...@gm...>]

Hello!

I've been trying to use more than 16 channels in LinuxSampler but I have
failed once and again. I add a second instance in another REAPER track and
set a channel both in Qsampler and Jsampler Classic to "Device 1", but it
doesn't work (I'm mostly using the latest Lv2 version). With the old vst
version found in KXStudio, it seemed to work at first, but after reloading
the project everything was messed up - the instrument of the second device
assigned to the first -. If you have any insight about this, I'll be
grateful.

Thanks so much in advance.

--trust-server-cert is not needed and makes fetching the source files 
insecure. That option is typically used with Subversion servers that are 
running with a self-signed certificate (e.g. in a private LAN). We do have a 
valid signed certificate for svn.linuxsampler.org though.

libgig never had a 'make parser' rule. LinuxSampler has, but this is no longer 
needed for LinuxSampler either. So you can just delete this line.

I would adjust these dpkg commands a bit. Right now you are re-installing the 
same .deb packages several times. E.g. by using a less universal pattern like 
linuxsampler*.deb, etc.

[Linuxsampler-devel] gigedit crashes on save, doesn't save

[Brandon S. <bra...@gm...>]

Hi team,

I'm experiencing an issue with the latest version of gigedit. if anyone has
time to help me investigate please it would be appreciated!

On saving any file gigedit will crash. This happens in both live and
standalone mode, but if it happens in live mode, linuxsampler will crash as
well. The error message in standalone is:

** (gigedit:5147): ERROR **: 21:10:42.517:
unhandled exception (type unknown) in signal handler

Trace/breakpoint trap (core dumped)

gigedit 1.2.1.svn2
libgig 4.4.1.svn4
linuxsampler 2.3.1.svn23
Linux Mint 22
kernel 6.8.0-53-lowlatency

I'm unsure how to access the core dump, but if it is helpful and anyone can
point me in the right direction on how to save and/or access it i'll be
happy to post as well

Was able to test it tonight. It works! Had to do quite a bit of fiddling
around with jack, for some reason linuxsampler was not attaching its
outputs to any audio devices, but I was able to connect it manually with
qjackctl. If there is any more testing you'd like me to do, please feel
