[LinuxCNC/linuxcnc PR#318] Update configure.in

#1 – jepler 于 2017-08-19

Thanks for your pull request. However, I can’t reproduce the problem you report.

Here, I don’t have libtk-img-dev installed:
~~~~
$ apt policy libtk-img-dev
libtk-img-dev:
Installed: (none)…
~~~~

but the configure test succeeds:
~~~~
checking for img::png using /usr/bin/tclsh8.6… found
~~~~

Let’s try to understand why your experience was different, so that we can make the right change to fix it.

@jepler I was trying to build with tag v2.7.11 version of source code, on a Raspberry Pi with fresh installed Raspbian Stretch.

I was running src/configure with --with-realtime=uspace argument.

Sorry for my not-fully-examined pull request. I found my configure still succeeds after removinglibtk-img-dev. I played around a bit, and think the previous experience might be because that I installed tcl8.4 and tk8.4 according to the result of dpkg-checkbuilddeps and also installed tcl8.6 and tk8.6 afterward. But I can’t reproduce it steadily.
