Hey guys, i don’t know if the topic is right in this place. I wanted to get in touch to the IPFire build environment. I wanted to start with something small what i know it worked so I tried to recreate the packages google-authenticator-libpam and libqrencode mentioned in this topic [OpenVPN OTP Authentication](https://community.ipfire.org/t/openvpn-otp-authentication/1463/16) I used the following buildfiles: > **[ummeegge / google-authenticator-openvpn](https://gitlab.com/ummeegge/google-authenticator-openvpn)** > > google-authenticator-pam for OpenVPN on IPFire platform And the sources from here: > **[fukuchi/libqrencode](https://github.com/fukuchi/libqrencode/releases)** > > A fast and compact QR Code encoding library. Contribute to fukuchi/libqrencode development by creating an account on GitHub. The google-authenticator package works without any problems but the libqrencode package fails everytime with the following error: ``` + cd /usr/src/lfs + make -f libqrencode LFS_BASEDIR=/usr/src dist make: *** No rule to make target 'dist'. Stop. ERROR: Packaging libqrencode [FAIL] Check /root/ipfire-2.x/log/_build.packages.log for errors if applicable ``` The error occurs when building the packages. Building IPFire succeeds without any problems. Building the and installing the package manually in the chroot environment (via parameter **shell** ) works as well. Does anyone have a hint what I’m missing? Thank you Greetings Steffen ---

Hi Steffen, this repo provides the building files but not the also needed make.sh entries. Did you entered a line for libqrencode in make.sh ? Can be checked with e.g.: `grep 'libqrencode' log/_build.ipfire.log` As another idea, delete the libqrencode ROOTFILE from \*_/ipfire-2.x/conf/rootfiles/packages_ and make a clean build e.g.: ```bash rm /conf/rootfiles/packages/libqrencode ./make.sh clean ./make.sh build ``` the build system will create then the ROOTFILE for libqrencode on his own which you can find after the build has been finished under \*_/ipfire-2.x/log/libqrencode-4.0.0_, move it to \*_/ipfire-2.x/conf/rootfiles/packages_, comment the unwanted files, delete the ‘+’ from those files which you want (in my case only usr/bin/qrencode usr/lib/libqrencode.so.4 usr/lib/libqrencode.so.4.0.0 ) , rename the ROOTFILE from _libqrencode-4.0.0_ to _libqrencode_. You do not need to build then IPFire again clean, the trick is delete only the libqrencode files from \*_/ipfire-2.x/log_ (there should then be two since there is also the missing file) and rebuild it again with a `./make.sh build` Did build it with a Core 141 environment but will pull origin/next this weekend and will build it again then. As a first idea. May this helps. Best, Erik ---

Hey Erik, yes I added the line in the make.sh. When I create my own ROOTFILE the error occurs as well. Greetings Steffen ---

Hi Steffen, please check then the ‘dist:’ line and the next one in the libqrencode LFS file. It needs to be exact in this format (with SPACE and TAB). ```bash dist: @$(PAK) ``` –\> [https://gitlab.com/ummeegge/google-authenticator-openvpn/-/blob/master/build\_files/LFS/libqrencode#L57](https://gitlab.com/ummeegge/google-authenticator-openvpn/-/blob/master/build_files/LFS/libqrencode#L57) May this helps.

Hey Erik, I cheked the file and I seemed to have the space after the dist: during editing. Now everything works fine. Thanks for your help 🙂 Greetings Steffen
