TSC does not build with libsfml-3.0

[bell07]

In Gentoo the distribution package libsfml is upgraded to 3.0.

!!! existing preserved libs:
>>> package: media-libs/libsfml-3.0.1
 *  - /usr/lib64/libsfml-audio.so.2.6
 *  - /usr/lib64/libsfml-audio.so.2.6.2
 *      used by /usr/bin/tsc (games-arcade/tsc-9999)
 *  - /usr/lib64/libsfml-graphics.so.2.6
 *  - /usr/lib64/libsfml-graphics.so.2.6.2
 *      used by /usr/bin/tsc (games-arcade/tsc-9999)

@bell07

I have never installed or used Gentoo.

Please provide info how to:

1. Install some precompiled Gentoo distro, where I don't need to wait for compiling.
2. Script or commands, how to install all dependencies required to build TSC.

#error "Enable C++17 or newer for your compiler (e.g. -std=c++17 for GCC/Clang or /std:c++17 for MSVC)"

Well. Our CMakeLists.txt has this:

set(CMAKE_CXX_STANDARD 11)

You can try to increase it to C++17, but I foresee that this is going to break building CEGUI. In that case, we will probably have to build an older version of SFML ourselves and ship it with TSC as there is no manpower available to phase CEGUI out of TSC, a problem that has been discussed over and over again on this tracker, in IRC, etc.

@xet7 I do not think the issue is Gentoo related, but should appear in near feature in other distros too. Maybe it does sense to create an AppImage or Flatpack that includes old libsfml, to keep the game playeable by users.

Gentoo is often underestimated ;( . In the meantime Gentoo provides binary packages too. Portage decides per package if binary is usable or package should be compiled. In gentoo both libsfml versions are in portage, so I solved the issue by specifying the version in the ebuild (gentoo build instruction). But this disallow me to install the tsc and dolphin-emu at the same time, because dolphin require the libsfml-3 :-(

If you like just to try to compile tsc for gentoo without execution, you can use stage3 and chroot. I tried this today:

Use gentoo stage3 and chroot to compile tsc and play around

Step 1: Download "amd64 / Stage 3 / desktop profile / openrc" from https://www.gentoo.org/downloads/

Step 2: Extract

mkdir gentoo
cd gentoo
tar xpvf /path/to/stage3-*.tar.xz --xattrs-include='*.*' --numeric-owner

Step 3: enter gentoo chroot (as root)
from https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Base

cp --dereference /etc/resolv.conf ./etc/

mount --types proc /proc ./proc
mount --rbind /sys ./sys
mount --make-rslave ./sys
mount --rbind /dev ./dev
mount --make-rslave ./dev
mount --bind /run ./run
mount --make-slave ./run

# Enter chroot
chroot . /bin/bash

source /etc/profile
export PS1="(chroot) ${PS1}"

Step 4: (in chroot) Configure package manager to use binary packages and my (bell07) repository

# Update portage
emerge --sync

# Enable binary packages
echo 'FEATURES="getbinpkg"' >> /etc/portage/make.conf

# Update developer gpg keys
getuto

# Install bell07 repository
emerge -va app-eselect/eselect-repository
eselect repository enable bell07
emaint sync -r bell07

# Accept "testing" tsc package
echo '=games-arcade/tsc-9999' > /etc/portage/package.accept_keywords/tsc

version 9999 means "latest git"

Step 5: Build tsc

emerge -va tsc

This build should not fail, because libsfml-2.6 is downloaded and used as dependency.

To get the error you can force the versions with

emerge --nodeps -va '=libsfml-3*' tsc

or you adjust the versions in the ebuild file by

nano /var/db/repos/bell07/games-arcade/tsc/tsc-9999.ebuild

If you like to try Gentoo without manual installation, you can try Redcore Linux or Calculate Linux. But I did not tried both yet. The Gentoo installation is not so long as expected if binary packages are used.

@bell07

Yes, there will be some additional packages sometime, when I figure it out #719

Any help and PRs welcome
