QCAD auf Webserver

[BastelFritz]

Code: Select all

user@server ~/opt/qcad-3.24.3-trial-linux-qt5.13-x86_64 # ./qcad -platform minimal -h
QCAD version  3.24.3
Warning:  QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-web64'
Warning:  This plugin does not support application fonts

./qcad: line 9: 31311 Segmentation fault      LD_LIBRARY_PATH="$DIR" "$binary" "$@"

QCAD has unexpectedly quit.

Please use the offscreen platform plugin for headless systems
(without a running X11 server):
./qcad -platform offscreen

In addition, you might have to override the default Qt style
to prevent the loading of a native desktop style (such as GTK):
./qcad -style plastique

Interessanterweise kommt bei dieser Version heute nicht die Meldung "Fontconfig error: Cannot load default config file", die am 17.4. kam, weiter oben sieht man es ja noch. Bei fc-list kommt die Meldung aber auch heute.

Das Verzeichnis wird erstellt und ist leer: '/tmp/runtime-web64' => Schreibrechte da sind also vorhanden.

Ich habe noch mal die Befehle mit gdb ausgeführt:

Schritt 1:

Code: Select all

user@server ~/opt/qcad-3.24.3-trial-linux-qt5.13-x86_64 # LD_LIBRARY_PATH=. gdb --args ./qcad-bin -platform minimal -h

Die Speicherreservierung geht hier wohl schief.

Kannst du mal den Speicherverbrauch des Servers beobachten während QCAD startet (z.B. mit top in separater Shell)? Kann sein, dass der Server am Limit läuft.

Alles verrammelt:

Code: Select all

user@server ~ # top
Error, do this: mount -t proc proc /proc
user@server ~ #  mount -t proc proc /proc
mount: only root can use "--types" option
user@server ~ # cat /proc/meminfo
cat: /proc/meminfo: No such file or directory
user@server ~ # free
Error: /proc must be mounted
  To mount /proc at boot you need an /etc/fstab line like:
      proc   /proc   proc    defaults
  In the meantime, run "mount proc /proc -t proc"
user@server ~ # cat /etc/fstab
cat: /etc/fstab: No such file or directory
