I should soon be able to test AMD proprietary and AMDGPU, in a virtual machine but using GPU passthrough, so it should mirror native exactly.
EDIT: nevermind. It looks like linux does not like booting in that virtual machine. I'll have to install it on my pendrive and actually test natively... It will take more time than I thought.

I've got some stuff to report.

Downloaded and tested: https://bitbucket.org/rude/love/issues/ ... d64.tar.gz

First of all, LÖVE 0.10.2 runs successfully with ./love, so all is good (checked the version just to be sure).

However, ldconfig fails because it's in /sbin and there's no path there by default, so I get an error:

Code: Select all

./love: 4: ./love: ldconfig: not found
causing the libstdc++ path to be added regardless of having a good libstdc++. Does /sbin/ldconfig work in all systems?

<EDIT>
Maybe this works:

Code: Select all

LDCONFIG=ldconfig
type "${LDCONFIG}" > /dev/null || LDCONFIG=/sbin/ldconfig
"${LDCONFIG}" -p | ...
Verified to work with bash, dash and busybox sh ('type' is an internal command in all three; 'type -p' doesn't work in dash).

i tested love-0.10.2-amd64 on Xubuntu 16.04.1 x86-64 with this output from uname -a
4.4.0-46-generic #67-Ubuntu SMP Thu Oct 20 15:05:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
and it loaded perfect without any output in terminal (standard love no game animated screen)

will this allow for easier cross-distro use for love2d?

great job everyone

I was very confused by that vendor string too, but I was not running vmware, it was native, and from what I can tell it was nouveau.
As extra confirmation, I tried on another box I have which is NVIDIA and got the Super Toast screen using love-0.10.2-amd64 and it shows "nouveau" instead of "vmware"...

Thanks for the heads up, I will look into this.

That's sounds about right, the vdso is a kernel thing, so not portable (and I don't think it's on the filesystem anyway), the runtime linker was skipped on purpose (that's ld-linux*), and the others are all part of libc, which I also skipped on purpose.

I'm wondering about this.

First, are the problems with the included libstdc++ related to a mismatched libc? Would including libc solve them?

Second, how frequent is it to not have libstdc++ installed? That possibility seems remote to me. Could the check ask the user to install it instead of providing one? It seems to me like a fairly reasonable thing to ask to Linux users.

No, apparently the open source AMD drivers require libstdc++, and on some systems require a newer libstdc++ version. If there's a libstdc++ installed, I'm assuming it's at least as new as the one I'm shipping.
