Building on windows gives "LINK : fatal error LNK1189: library limit of 65535 objects exceeded [D:\repos\libossia\build\src\ossia.vcxproj]"

Hi!

When I try to build the latest master on windows I get the following:

PS D:\repos\libossia\build> cmake --build . MSBuild version 17.11.2+c078802d4 for .NET Framework

I cloned, submodule updated, ran cmake, and cmake --build, with no settings changed. I suppose that's not how you build libossia for ossia score on windows?

[jcelerier]

hum that's strange, ossia score bundles libossia and exports much more symbols, yet less than the 65k limit. I'll investigate. Can you share the link line ? Also I see that MSVC is bundling a lot of libraries but if you only use libossia for oscquery you can really slim it down with -DOSSIA_OVERRIDE_PROTOCOLS=OSCQUERY -DOSSIA_EDITOR=0 -DOSSIA_DATAFLOW=0, this way it won't build with e.g. wiimote support, FFT and a full-blown DAW & dataflow system builtin :)

[jcelerier]

Not on windows at the moment but if on linux I build in release with these flags:

$ nm -CD src/libossia.so  | egrep ' (T|t) ' | wc -l
1235

I get 1235 exported symbols (in particular I'm seeing that re2 symbols are mistakenly exported... will fix that but that's still just 328-ish symbols).

[jcelerier]

I get around the same number in debug mode. I'll try with MSVC on windows.

Hi, I was traveling for a while and left my dev machine at home so I couldn't follow up on this, but now I'm back.

I pulled master and tried building again just in case, That didn't make a difference, so I configured with "-DOSSIA_EDITOR=0 -DOSSIA_DATAFLOW=0" and built again. It still reached the limit.

So I added "-DOSSIA_OVERRIDE_PROTOCOLS=OSCQUERY", configured and built, that worked fine!

All the above were with a debug build configuration only, I should add.

I've since tried a release build, and actually with that there's no problem!

But I guess I can leave the issue open since it persists with the debug build?

Thanks for looking in to this!

Now on to making my old code work with this new release - I imagine there might have been some breaking changes, the build I use is a few years old, 1.0.x IIRC :)

[jcelerier]

hmm since 1.0 there actually shouldn't be too many deep changes for the oscquery part, unless you opt-in to the new class that work with a boost.asio context (in order to have more control over threading, etc)

[jcelerier]

and yes, I still want to make sure that it's possible to produce workable debug builds! Although I assume this is happening because of no inlining at /O0..

Hi,

This is along the same lines, so I figured I'd write in the same thread, even if it's not the exact same issue.

Building and running on Windows worked fine:

cmake .. -DOSSIA_EDITOR=0 -DOSSIA_DATAFLOW=0 -DOSSIA_EXAMPLES=1 -DOSSIA_CPP=ON -DOSSIA_OVERRIDE_PROTOCOLS=OSCQUERY cmake --build . --config Release Finally cmake --build . --config Release --target INSTALL Created a folder with include / bin / lib folders that I could use to add libossia to my project. There were some refactors in my code needed since it was old, but nothing dramatic.

NOW, I want to replicate this on MacOS.

But, the result is not comparable - when I run target install, the include folder doesn't contain a boost subfolder for example.

And when I try to build on mac pointing to that folder, it fails because it doesn't find a "variant":

if __has_include(<boost/variant2.hpp>)

include <boost/variant2.hpp>

namespace ossia_variant_alias = boost::variant2;

else

include <mpark/variant.hpp> <---- it fails here

namespace ossia_variant_alias = mpark;

endif

NOW, if I copy over the "install" folder from windows, it works, and builds, but I'm not sure that's the best solution!

Also, with the above, I get OSC Query working, BUT, when I try to delete the generic device, created as follows:

std::make_unique(std::unique_ptr(protocol), "Mirror");

I get a crash:

libossia.dylib`ossia::net::generic_device::~generic_device: 0x109c53364 <+0>: sub sp, sp, #0x20 0x109c53368 <+4>: stp x29, x30, [sp, #0x10] 0x109c5336c <+8>: add x29, sp, #0x10 0x109c53370 <+12>: str x0, [sp, #0x8] 0x109c53374 <+16>: ldr x0, [sp, #0x8] 0x109c53378 <+20>: str x0, [sp] 0x109c5337c <+24>: bl 0x109c5331c ; ossia::net::generic_device::~generic_device() -> 0x109c53380 <+28>: ldr x0, [sp] 0x109c53384 <+32>: bl 0x10a09e968 ; symbol stub for: operator delete(void*) 0x109c53388 <+36>: ldp x29, x30, [sp, #0x10] 0x109c5338c <+40>: add sp, sp, #0x20 0x109c53390 <+44>: ret

And one step in:

The above is from a debug build on MacOS, sorry I'm not a Mac dev - at all - and so the stack trace might not be the most useful, I'm not sure why it doesn't contain debug info, the dylib I use IS a debug build.

The exact same code works fine on Windows. I get the crash both with the master branch, and with v2.0.0-rc4, on Mac. On Windows I just use master.

Can the above instability be because I use the include folder created on windows? or is it a bug?

My code is attached here in case it's useful - with a lot of debug printing, TODO's etc, since it's not production code...

The methods that are relevant are void OSCQueryAddress::connectAndQuery(), and, disconnect(), which is where the crash happens, when I set m_Device to nullptr.

It won't build and run, but it might give you a view. It worked fine with the older libossia version for years, and works also now on windows - the only change I've made after the update is comment some secondary functionality that wasn't building any longer, and to use the .osc_address() field on the node instead of the "ossia::net::osc_parameter_string(n);" call of before.

If there's any more information you need, or if it's easier in any way to diagnose, feel free to email also, it's onar3d at gmail. Thanks!

On that note - I don't want to build from source unless I have to of course, maybe there is a distribution I can download and use? I didn't find any recent one on gihub.

Also, maybe I should get cmake to create a .framework from libossia? Currently it's "just" a dylib, created with the same configuration as for windows. I saw a framework option in CMAKE, is that what it's for?
