08:32 <Guest94> hello, the kernel building system cannot find <sys/types.h> while I was compiling it

08:32 <Guest94> well, I cannot find it too

08:32 <Guest94> I tried `tar -tJvf "$pkg_name" | grep`ping the content

08:33 <Guest94> ... on the installation media `crux-3.6.1.iso` without finding it

08:34 <Guest94> installation done in a chroot, using `rootfs.tar.xz` inside one chroot to bootstrap another

08:34 <Guest94> md5 checked

08:34 <cruxbot> [contrib.git/3.6]: rust-analyzer: 2021-10-11 -> 2021-10-18

08:35 <Guest94> well, that's either a severe enough bug sufficient to repel off all outsiders using this distro, or my stupidity

08:36 <Guest94> it's `<sys/types.h>`, used by practically *everywhere*

08:37 <Guest94> s/using/attempting to use/

08:43 <SiFuh> Found in /usr/ports/core/glibc: /usr/include/sys/types.h

10:07 <Belgacem1958> Has anyone succeeded in installing "rstudio" ? Problem with "ant" which does not want to install.

10:09 <pedja> what's the actual error?

10:10 <pedja> 'does not want to install' doesn't mean much

10:11 <Belgacem1958> It's from apache-ant : error compiling

10:13 <pedja> paste the build output somewhere, share the link to it

10:14 <Belgacem1958> Ok, thank you. I will do it

10:30 <Guest94> SIFuh: hey I don't really have this file

10:30 <Guest94> got it

10:31 <Guest94> weird

10:31 <Guest94> used official `setup` script and this header had never been installed

10:32 <Guest94> weird

10:55 <Belgacem1958> This is the "ant.log" while attempting to install it from contrib collection : https://pastebin.com/9U3L1GAA

11:02 <Romster> https://repo1.maven.org/maven2/ is working for me here

11:02 <Romster> tried again?

11:04 <Romster> https://crux.ster.zone/packages/3.6/contrib/ant%231.10.11-1.pkg.tar.xz

11:04 <Romster> change the %23 to # and you can pkgadd that if you don't have any luck

12:21 <cruxbot> [opt.git/3.6]: libsdl2: switch buildsystem to cmake, add several optional deps

12:21 <cruxbot> [opt.git/3.6]: mpg123: update to 1.29.1

14:54 <Belgacem1958> When compiling openjdk8, this message appears : "cp: failed to preserve ownership for /home/pkgmk/work/openjdk8/pkg/usr/lib/java/openjdk8/jre/lib/amd64/server/libjsig.so: Operation not supported". Any solution you may suggest?

18:08 <farkuhar> Belgacem1958 was trying to build contrib/ant as an unprivileged user (fakeroot pkgmk), but ant doesn't play nicely with fakeroot. The only workaround I found was to run pkgmk as root, just for this one port.

18:10 <farkuhar> When I brought this up several months ago, pedja pointed out that "does not build under fakeroot" should be considered an upstream bug, not the fault of any crux packager.

18:40 <stenur> 'could try to use unshare(1) which can have its own uid/git mapping

19:03 <jeremyc> Anyone have a tutorial on how to make your webcam work in Crux? Need it for work and have been failing all weekend long :-(

19:10 <pedja> define 'failing'. kernel doesn't recognise it or ?

19:11 <jeremyc> pedja: yeah, I should have been more clear. Yes, I can not get /dev/video? to show up. I've went through about 12 iterations of kernel compiles, some working, some I broke things. I'm now on 5.14.13, but still no luck. On other Linux distros it works fine, so I'm sure it's just kernel options and maybe mod probe stuff. I'm a bit out of my element here.

19:14 <pedja> jeremyc, when you plug it in, is there anything in dmesg/lsusb output?

19:15 <pedja> uvcvideo kernel module is the most common one webcams use, iirc

19:15 <jeremyc> [ 811.306656] usb 1-4: new high-speed USB device number 7 using xhci_hcd

19:15 <jeremyc> lsusb reports: Bus 001 Device 007: ID 046d:082d Logitech, Inc. HD Pro Webcam C920

19:17 <jeremyc> Do you have to do anything with V4L?

19:19 <pedja> only as a sanity check 'v4l2-ctl --list-devices'

19:19 <pedja> or to see if there is stuff that can be configured for it

19:20 <jeremyc> OK, I just wiped my (now really messed up) /usr/src/linux-5.14.13 tree, gonna start from scratch on that. I think I went overboard enabling everything I could see relating to webcam/video/V4L/multimedia...

19:21 <pedja> uvcvideo is the generic driver, so start from there

19:25 <pedja> jeremyc, https://linux-hardware.org/?id=usb:046d-082d

19:26 <pedja> afaict, that's kernel config required to make it work

19:29 <jeremyc> pedja: thanks. I copyied 5.4.80's .config to 5.14.13/.config and did a make olddefconfig then booted into 5.14.13 just now. I'll go start w/just that module.

19:34 <jeremyc> pedja: that's a pretty cool website, I'll show my ignorance here and admit, I didn't know of it.

19:34 <pedja> jeremyc, don't feel bad, 'proper' kernel .config is kind of tricky :)

20:13 <Belgacem1958> <farkuhar>: probably after disabling "makecommand sudo -H -u pkgmk f

20:15 <Belgacem1958> <farkuhar>: probably after disabling "makecommand sudo -H -u pkgmk fakeroot pkgmk" in /etc/prt-get.conf, the compilation of openjdk8 will success with root user? Maybe!

20:26 <Belgacem1958> now i start to have a nice setup with CRUX, however i'm missing some tweaks to make my HP1005P printer work, i made the sound work (alsa service started) once but i don't have it after restarting. I have to fight to install Rstudio. I am a research scientist and I need Rstudio, Octave Julia, Neovim. I will see how to proceed to install Julia who is not in the ports.

20:40 <pedja> is using miniconda an option?

20:48 <Belgacem1958> Do not know exactly?

20:56 <pedja> https://www.anaconda.com/products/individual

20:57 <pedja> that's a full installer, and miniconda is at https://docs.conda.io/en/latest/miniconda.html

20:57 <pedja> afaict, julia-1.6.3 is the latest available

21:00 <Belgacem1958> But i think anaconda is python rather than julia.

21:07 <pedja> julia, rstudio, octave are all easily installed using conda, anaconda's package manager.

21:07 <pedja> it did start with python, but support for other languages used in data science was added over time

21:08 <pedja> python, julia, r

21:11 <pedja> all separate from system packages and maintained by large active community, which is neat, because I am lazy :)

21:22 <Belgacem1958> PEDJA : ok, great! But not conflicting with the already installed Python!

21:23 <pedja> no, it installs/runs from home dir, using virtual environments

21:24 <pedja> check the docs in the links I posted, if you are curious how it works

21:24 <Belgacem1958> I know that i can i install anaconda using pacman with ArchLinux, but never tried installing it with Crux. I guess it's also easy to do so.

21:25 <Belgacem1958> Thank you for your kind help

21:27 <pedja> np

22:31 <stenur> pedja: linux-hardware.org is a great thing, thanks!
