Compile problems

please tell me how to fix this problem....?


checking whether readline license is compatible with GPL-2... no
configure: WARNING: The LinuxCNC binary you are building may not be
distributable due to a license incompatibility with LinuxCNC (some portions
GPL-2 only) and Readline version 6 and greater (GPL-3 or later).

did you try:

sudo apt-get install libreadline-gplv2-dev

?

Hi,

If i read this :

To configure LinuxCNC in this way, you must
invoke configure with "--enable-non-distributable=yes"

Can the solution be in terminal at the point of mr.singh installation :

cd src
./autogen.sh
./configure --enable-non-distributable=yes

document : github.com/KurtJacobson/RF45-CNC/wiki/Bu...LinuxCNC-From-Source

It's a very strange message. It looks like someone has made a macintosch or apple application inside linuxcnc.

@Andy,
It's nice to see a admin doing his job !

Not a strange message just a "debian thing" lol

Solution: on recent version of Debian and Ubuntu, please install libeditreadline-dev which is still GPL2 for dependency fullfillment.

1. if you have installed libreadline-dev remove by

   sudo apt remove libreadline-dev

2. and install still GPL2 compatible libreadline via

   sudo apt install libeditreadline-dev

3. Build the package again by

   dpkg-buildpackage -b -uc

You should not encounter the error now.
Background: I faced the same problem, and I was compiling on RPi 400 (4GB) with Ubuntu 22.04 LTS (jammy). Reason was readline versions are GPL3 (libreadline-dev) but Latest repo of Debian and Ubuntu don't have GPL2 compatible versions on standalone. Some other product was facing this issue (matter of fact MariaDB) so they used libeditreadline-dev as GPL2 compliant requirement is fullfilled by this flavor of readline. worked for me too.
