[LinuxCNC/linuxcnc Issue#325] missing runtime dependency check in src/configure About GRBL HAL

Issue #325 | 状态: 已关闭 | 作者: SebKuzminsky | 创建时间: 2017-09-08

Fresh install of Xubuntu 17.04 “Zesty”, checked out the master branch, ran “debian/configure uspace”, satisfied dpkg-checkbuilddeps. Built linuxcnc and ran it, selected the sim/axis/axis config, and got this error:

~~~

Looks like a missing runtime dependency check in src/configure. Fix should go in 2.7.

Installing python-gtk2 fixed it.

It’s probably not a bug in the debian packaging ,but maybe a bug in how we think about setting up new systems to run LinuxCNC-built-from-source.

(that is, it’s totally not a bug for a source package to NOT depend on something that’s not used until runtime)

I agree.

Just like how src/configure without --disable-check-runtime-deps reminds the user to install bwidget, libtk-img, and tclx, since they are needed to make use of a run-in-place build, so it should remind the user to install python-gtk2 (or Axis won’t run).
