Build 3.3.1 on CentOS 7

VVD commented 1 year ago

Question

CentOS 7.9.2009 x86_64 with all updates installed. GLIBC 2.17.

* Linux: Shared libraries are now built on Ubuntu 18.04 (up from Ubuntu 16.04) (B)
    - GLIBC versions older than 2.14 are no longer supported. Some, but not all, LWJGL natives may require up to GLIBC 2.27.
    - Applications deployed on older systems must now build & bundle custom LWJGL natives. Contact LWJGL developers if you need assistance.

Steps got from different places - can't find instruction:

wget https://github.com/LWJGL/lwjgl3/archive/refs/tags/3.3.1.tar.gz
tar -zxf 3.3.1.tar.gz
cd lwjgl3-3.3.1
export ANT_OPTS=-Xmx2G
export LWJGL_BUILD_TYPE=release/3.3.1
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk/bin/java
ant compile-templates
ant generate
ant compile

Without erros: BUILD SUCCESSFUL

But this one fails:

ant compile-native

gcc 4.8, no stdatomic.h, no support for -std=gnu++14… Installed devtools-11 in /opt/rh/devtoolset-11/root/, so full path to gcc 11 is /opt/rh/devtoolset-11/root/usr/bin/gcc.

How to say to ant where to search gcc?

And I see one more error: Can't find glibconfig.h, but:

$ find /usr/ -name glibconfig.h
/usr/lib64/glib/include/glibconfig.h
/usr/lib64/glib-2.0/include/glibconfig.h

Hey @VVD,

You can see the required Linux dependencies here: LWJGL-CI/lwjgl3.

It should be possible to use a non-default GCC by passing -Dgcc.version=11 to the ant build.

Hey @VVD,

Hello, @Spasi!

You can see the required Linux dependencies here: LWJGL-CI/lwjgl3.

I'll check, thanks.

It should be possible to use a non-default GCC by passing -Dgcc.version=11 to the ant build.

But how set path to it (like JAVA_HOME, but for GCC)?

Spasi commented 1 year ago

I don't have experience with CentOS, but this makes it sound simple.

VVD commented 1 year ago

@Spasi . /opt/rh/devtoolset-11/enable switch default gcc to 11. Require devtoolset-11-libatomic-devel too.

But there are other errors:

preadv2:

preadv2() and pwritev2() first appeared in Linux 4.6. Library support was added in glibc 2.26.

https://manpages.debian.org/testing/manpages-dev/preadv2.2.en.html

Is it possible to build lwjgl 3.3 with glibc 2.17?

One more (didn't explore what is it, but know that io_uring is very new feature in Linux):

Workaround "dirty hack":

ln -s /usr/lib64/glib-2.0/include/glibconfig.h /usr/include/glib-2.0/glibconfig.h

So 3rd error "resolved".

But 1st and 2nd are here.

VVD commented 1 year ago

I don't see any preadv2 usage in code of lwjgl3. Function just exported for external usage. So this is my workaround:

On Ubuntu 20.04 it have line `typedef int __bitwise __kernel_rwf_t;`, but on CentOS 7.9 no this line.

Hey @VVD,

I'm sorry about the troubles you're having. Unfortunately, it's become impossible to build LWJGL (and all its dependencies) on older Ubuntu systems. Github does not even offer a CI runner with Ubuntu 16 and even 18 is getting deprecated soon. That's why we basically require a newer glibc version (which is already 5 years old btw).

On LWJGL's side, your best bet is simply disabling the liburing bindings and commenting out any functions that are not available on your system. I'm talking about the Kotlin template code that defines the bindings. Run the generator again and they'll be gone, you should then be able to build LWJGL on your system.

For dependencies like GLFW, I can't help I'm afraid. They may be fixable with some simple patches. See this account, it includes all dependencies necessary for LWJGL. The latest commit in every project contains all the LWJGL-specific changes (or just the Github Actions workflow file).

Btw, indeed, the ant release command by default downloads the prebuilt binaries from LWJGL-CI. If you'd like to test a release with custom binaries, add -Dbuild.offline to the command.

Finally, a stupid question probably but, why don't you upgrade to CentOS 8?

ws909 commented 1 year ago

@VVD GLFW development is far too slow to not build from the master branch. It can take years between the releases.

@Spasi, I'm run software on FreeBSD with Linux environment based on CentOS 7 - no other choice.

Spasi commented 1 year ago

Hey @VVD,

LWJGL 3.3.2-snapshot+11 is now available. The x64 build should run fine on CentOS 7, or any other Linux distribution with GLIBC 2.17 or later.

LWJGL binaries are now built inside a base CentOS 7 container, running on the ubuntu-latest GitHub Actions runner. The magic that unlocked this possibility is provided by centos-release-scl and devtoolset-11-gcc-c++. It somehow works with the old GLIBC in CentOS 7 and can build all LWJGL dependencies without trouble. All LWJGL-CI projects have been updated, for details see the lwjgl.yml files in each repo.

Please let me know how testing goes.

Hey @VVD,

Based on the above, the LWJGL core and GLFW native libraries seem to be loading and executing properly, so the GLIBC issue is fixed. There's nothing LWJGL can do about the error you're seeing, looks like there's no OpenGL driver available. Does glxgears work on that machine?

VVD commented 1 year ago

Hello, @Spasi! Ofc work. Old version of the same application with 3.2.2 work fine and other OpenGL applications work too. Newer version of the application require LWJGL 3.3.1+ and show this error after replace bundled 3.3.1 with 3.3.2-nightly.

Thanks for help!

Spasi commented 1 year ago

The failed to load driver: swrast message seems to suggest that a Mesa driver is being picked up somehow. See this for example: https://askubuntu.com/questions/834254/steam-libgl-error-no-matching-fbconfigs-or-visuals-found-libgl-error-failed-t

LWJGL's method to load the OpenGL driver hasn't changed since 3.3.1. You can verify which library is being loaded by running the application with -Dorg.lwjgl.util.Debug=true -Dorg.lwjgl.util.DebugLoader=true.

I do see a change in GLFW though, with this commit: https://github.com/glfw/glfw/commit/c18851f52ec9704eb06464058a600845ec1eada1. If libGLX.so.0 is available in your system and GLFW is indeed loading it, you can override that by calling GLFWNativeGLX.setPath(GL.getFunctionProvider()); before initializing GLFW.

I do see a change in GLFW though, with this commit: https://github.com/glfw/glfw/commit/c18851f52ec9704eb06464058a600845ec1eada1. If libGLX.so.0 is available in your system and GLFW is indeed loading it, you can override that by calling GLFWNativeGLX.setPath(GL.getFunctionProvider()); before initializing GLFW. It's not my application. It's binary distributed application. Decompile, patch and recompile… don't really want to do this…

Then maybe try building and running the HelloWorld sample from https://www.lwjgl.org/guide? See if that reproduces the issue and if GLFWNativeGLX.setPath(GL.getFunctionProvider()) fixes it.

Hello LWJGL 3.3.2-snapshot+13!

And I see red window now!!!

Maybe you have tips how to "fix" application? :-o

Spasi commented 1 year ago

OK, great, that verifies that the problem is GLFW loading libGLX.so.0 instead of libGL.so.1.

From your side

You first need to understand why that doesn't work. Maybe something is broken on your system? Have you tried reinstalling mesa and your GPU driver? Note that it doesn't matter that LWJGL doesn't try to load libGLX because the application crashes on GLFW window creation, before LWJGL's GL code runs.

Btw, libGLX comes from https://github.com/NVIDIA/libglvnd.

Assuming that is fixed, without changing LWJGL or the application, you could run the application with -Dorg.lwjgl.opengl.libname=libGLX.so.0. This will ensure that GLFW and LWJGL load the same OpenGL library.

From LWJGL's side

It's kind of late now that 3.3.2 has been released. In the first 3.3.3 snapshot, I could add a command line flag that makes LWJGL call GLFWNativeGLX.setPath(GL.getFunctionProvider()) internally on glfwInit. This would let you run the unmodified application by forcing GLFW to load libGL.so.1 directly.

VVD commented 1 year ago

Maybe -Dorg.lwjgl.opengl.libname=libGL.so.1? Tried different values without success. But mv libGLX.so.0.0.0 libGLX.so.0.0.0_ fixed run of this application!!! Thanks!!! Hope developers will update embedded LWJGL to 3.3.3 soon…

My system is FreeBSD 13.1 amd64 with installed CentOS 7 environment (from ports) in Linuxulator. :-D

Because (AFAIK) LWJGL no longer supports FreeBSD I run Linux application in Linuxulator. :-(

@Spasi you might be interested in using a different method pioneered by chromium. Reversioning the libc6 symbols on the build system to make gcc link to lower versions of GLIBC. It is affective for building on many projects comprised of C code. I am not sure about C++.

Here is an example implementation for an application built fully on GitHub actions focal amd64 and cross compiled for armhf, arm64, i386, and native amd64. The resulting binaries link to GLIBC 2.17 though in theory you can go even lower.
