Thanks very much for providing these, Wayne. I rebuilt hplip (after uninstalling the one I'd previously installed) following your script, except that I added --disable-network-build to configure because I don't have net-snmp installed; the build went through without error. I ran `make check' since it is in your script, but it returned "Nothing to be done for 'check'." The installation also went through without error. I then followed your script to install the hplip plugin. I wondered why your script uses the version 3.19.5 plugin; is it because 3.19.6 was not yet available when you made the script, or did you have problems with the 3.19.6 plugin? Anyway, I adhered to your script and downloaded the 3.19.5 runfile and followed the script instructions, though I hesitated when I saw you have systemd as a required dependency, since my BLFS is the non-systemd version; nevertheless, the installation went through without error. Then I turned on my HP device and successfully printed out a test page, and then I ran `scanimage -L', and to my delight, it identified my device. But then I ran `scanimage >image.pnm', and it returned "open of device hpaio:/usb/HP_ColorLaserJet_MFP_M278-M281?serial=VNBNM1K0H8 failed: Error during device I/O" and the plug-in installer window popped up saying "HP Device requires proprietary plug-in which is missing." I cancelled the dialog rather than continue with the plug-in installation. I assume you didn't have this problem? In reviewing what your plugin instructions install, I noticed several libraries were missing that had been installed when I had previously installed the plugin using the hp-plugin script, and which are also installed in my openSUSE Tumbleweed, namely hpgt2500_ntdcmsdll-x86_64.so, libsane-hp2000S1-x86_64.so.1.0.25, libsane-hpgt2500-x86_64.so.1.0.27 and libjpeg-x86_64.so.9.2.0. So I added the first three to /usr/lib/sane and the libjpeg to /usr/lib, made symlinks leaving out the architecture and version bits. Then I ran `scanimage >image.pnm' again and it immediately segfaulted. By process of elimination I determined that having libsane-hpgt2500-x86_64.so.1.0.27 in /usr/lib/sane is what causes the segfault, while with either or both of the other two libraries in /usr/lib/sane, there is no segfault but hplip thinks no plugin is installed. (The presence or absence of libjpeg.so.9 didn't make a difference.) So it seems libsane-hpgt2500-x86_64.so.1.0.27 is needed for the scanner on my device to function, yet it causes a segfault in BLFS, though not in openSUSE Tumbleweed. I guess now it's time to take this to an hplip forum or bugtracker, unless you or someone else can think of something else to try. I am curious, though, where you found the information to make the plugin build script; I could not see it in the shell script part of the plugin runfile, in particular, which files to install where and which not to install. Did you find it somewhere on the web? > Regards, > Wayne.
