[Solved] lcd4linux installation
Hi,
I'm trying to get LCD4Linux installed on my machine (due to my obscure usb lcd being unsupported by lcdproc)
I wasn't able to install using the AUR package due to the issues mentioned in the comments there.
I've tried instead to install from source (git repo), however I'm met with errors that exceed my software compilation knowledge.
Here is what I have run to get as far as I have:
git clone https://github.com/jmccrohan/lcd4linux.git
cd lcd4linux
mkdir m4
autoreconf -fvi -I /usr/share/gettext/m4 # (I got even less far without this)
./configure --with-drivers=serdisplib --with-plugins='!all'
makeHere is the error I'm facing during 'make':
$ make
make all-am

Re: [Solved] lcd4linux installation
Why don't you use the PKGBUILD you linked and modify it to patch for the comment made on Jul 28 to use `m4_pattern_allow` ? Rather than going all the way back to upstream / square 1 and reinventing the wheel? I assume the AUR package would have already solved the problems you list here and once you fix them you're probably back to where you started and STILL have to patch for that AM_ICONV error.

Thanks for the suggestion. I'm not clear on how to do that though, since I'm really just guessing at this point : - )

Have you tried that?

You would be wrong.

You were almost there you needed to change the CFLAGS to change the default C standard from gnu23 to gnu17 see https://src.fedoraproject.org/rpms/lcd4 … 8a1a501ae9. Apply the following diff to the current AUR lcd4linux-git:

Re: [Solved] lcd4linux installation
Thank you @loqs - that worked perfectly.
Once that was built and installed, some manual compiling and symbolic linking of serdisplib and my alphacool lcd is now working again! Yey!
