Torque 3D package works but requires sudo

lemurni · 2017-08-08 22:11:18

This is my first post on the Arch forums. I am trying to create a AUR package for Torque 3D game engine. :)

I have written the following files

PKGBUILD -> gets latest stable GitHub release of precompiled binaries, installs whole directory in /opt/torque3d-bin, installs launcher and desktop entry
torque3d.desktop -> desktop entry for the launcher below
torque3d_launch.sh -> installed in /usr/bin, simply cd to torque3d-bin install dir to run from there

Basically everything is working, after makepkg and pacman -U <pkgname>.pkg.tar.xz i can start ./Torque3D from the torque3d-bin install directory (only from there!). HOWEVER, it crashes unless i use sudo, which is unacceptable.
Note: the same happens when installing to /opt/torque3d-bin and ~/torque3d-bin (just wanted to test that).

When i download the 3.10 binary sources from the GitHub repo, it works out of the box. I haven't been able to figure out the difference though.

PKGBUILD

	# how to avoid it being copied in the srcdir in the first place?
	cp -R ${srcdir}/* ${pkgdir}/opt/${pkgname}
	chmod 755 -R ${pkgdir}/opt/${pkgname}
	rm ${pkgdir}/opt/${pkgname}/torque3d.desktop
	rm ${pkgdir}/opt/${pkgname}/Torque3D-${pkgver}-LinBinaries.zip

	# install launcher shell script
 	# launcher is required to cd to install dir before running
 	install -m755 torque3d_launch.sh ${pkgdir}/usr/bin/torque3d

	# install .desktop entry and icon
	install -m755 torque3d.desktop ${pkgdir}/usr/share/applications
	install -m755 ${srcdir}/core/torque.png ${pkgdir}/usr/share/pixmaps/torque3d.png

}

Desktop entry

[Desktop Entry]
Name=Torque 3D
Comment=Open-source cross-platform 3D game engine.
Exec=torque3d
Icon=/usr/share/pixmaps/torque3d.png
Terminal=false
Type=Application
Categories=Development;Game

Launcher script

#!/bin/bash

# enter install directory
cd /opt/torque3d-bin

# add path to system libs and launch
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${PWD} ./Torque3D

Do you have any idea what the issue might be?

Thank you very much!

Running namcap gives me the following (besides telling me to clean up the dependencies which i will definitely do)

torque3d-bin E: ELF file ('opt/torque3d-bin/libSDL2-2.0.so.0.4.1') outside of a valid path.
torque3d-bin E: ELF file ('opt/torque3d-bin/Torque3D') outside of a valid path.
torque3d-bin E: Missing custom license directory (usr/share/licenses/torque3d-bin)
torque3d-bin E: Insecure RPATH '/home/jeff/Desktop/310/Engine/lib/sdl' in file ('opt/torque3d-bin/Torque3D')
torque3d-bin W: Referenced library 'libSDL2-2.0.so.1' is an uninstalled dependency

Note: i am not jeff, maybe that is some leftover from the makefile? guess i may have to just install the libSDL2-2.0.sp somewhere else?

Normal users can do very little in /opt , the crash can probably be avoided by changing permissions on the torque folders.
full error output is needed.

The insecure rpath is a leftover from the sourcecode that should have been removed during build .
The binary includes SDL2 libraries, it is unlikely it will use system libraries

The reason everything is spread over $srcdir is that the zip file doesn't have a top level directory.
(very common for compressed files created by windows users ... )

I think prepending the source url with somename:: should lead to extracting to $srcdir/somename/ , but am not sure.
(man makepkg used to mention this , but doesn't anymore ? )

No, that just changes the download filename, which is typically done when upstream doesn't include a pkgver in the filename, or when you use Github archives that result in "v1.0.0.tar.gz" (since makepkg doesn't respect the content-disposition header or redirected server names).

What I would do is specify the file with noextract, then perform the extraction myself in prepare()

noextract=("${_pkgname}-${pkgver}.zip")
prepare() {
    unzip -qqo "${_pkgname}-${pkgver}.zip" -d "${_pkgname}-${pkgver}"
}
