@Augusto7743 Since the last merge (which will soon be 9.0.0, thanks to the hard work from @matteotenca), the minimum requirements have changed. This information is being updated in PR https://github.com/pkoutoupis/rapiddisk/pull/145. Anyway, you will now need the following library and development packages to build the user space utilities:

libjansson, libpcre2-dev, libdevmapper and libmicrohttpd

Augusto7743 commented 1 year ago

Thanks for replying sharing the new requirements. Thus I had installed the new requirements.

In Ubuntu 20.04.5 are installed libjansson-dev 2.12-1build1 libpcre2-dev 10.39-3ubuntu0.1~20.04.sav0 libdevmapper-dev 2:1.02.167-1ubuntu1 libmicrohttpd-dev 0.9.66-1 libselinux1-dev 3.0-1build2

Those aren't errors. Check your source directory. The binary files are built and there. The messages you are seeing are gcc suggestions printed because of the build flags used.

Augusto7743 commented 1 year ago

Thanks very much for saying it. In moment not tested your software in kernel 6.1 or 6.1.1. My kernel sources are having build fails. I need wait for an solution. Have an nice week.

pkoutoupis commented 1 year ago

@Augusto7743 Since it is a non-issue and the build actually completes and the messages are just gcc suggestions, can we close this issue? Or do you believe that it needs to be kept open for another but related reason? Thank you!

pkoutoupis commented 1 year ago

I added a note in the project Wiki: https://github.com/pkoutoupis/rapiddisk/wiki/Frequently-Asked-Questions-(FAQ)#why-am-i-seeing-warning-messages-saying-note-length-computed-here

Augusto7743 commented 1 year ago

Good action done. Today was released kernel 6.1.4 in my source kernel update https://launchpad.net/~tuxinvader/+archive/ubuntu/lts-mainline

Rapiddisk last master is working correctly. I will test with new kernel ... I will try install in another Ubuntu versions too and report the result.

Augusto7743 commented 1 year ago

Installed and tested in Ubuntu 18.04.5 32 bits working correctly too ...

Augusto7743 commented 1 year ago

Tested current master in Kernel 6.1.6. Working correctly. Have an nice week for you and the users.

pkoutoupis commented 1 year ago

@Augusto7743 I will close this issue since the original problem reported ended up being a non-issue. Thank you for testing all distros/kernels. It is very much appreciated. Feel free to continue reporting your testing in this ticket (even after it is closed). :-)

Augusto7743 commented 1 year ago

Thanks for releasing 9.0. Tested version 9.0 in Kernel 6.1.6 working correctly. When possible will be installed kernel 6.2 for tests.

Have an nice week and good luck in your life and for users too.
