zgv works fine if I start it before I start X11, but segfaults if I try to run it after I have started X11. I re-emerged zgv and the graphics libraries that zgv depends on (including glibc) but this did not change the problem. media-gfx/zgv-5.6 media-libs/svgalib-1.4.3-r4 Reproducible: Always Steps to Reproduce: Portage 2.0.48-r5 (default-x86-1.4, gcc-3.2.3, glibc-2.3.2-r1) ================================================================= System uname: 2.4.20-gentoo-r6 i586 AMD-K6(tm) 3D+ Processor GENTOO_MIRRORS="http://gentoo.oregonstate.edu http://distro.ibiblio.org/pub/Linux/distributions/gentoo" CONFIG_PROTECT="/etc /var/qmail/control /usr/kde/2/share/config /usr/kde/3/share/config /var/bind /usr/X11R6/lib/X11/xkb /usr/kde/3.1/share/config /usr/share/config" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" PORTDIR="/usr/portage" DISTDIR="/usr/portage/distfiles" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR_OVERLAY="" USE="x86 oss 3dnow apm avi crypt cups encode foomaticdb gif jpeg libg++ mad mikmod mmx mpeg ncurses nls pdflib png quicktime spell truetype xml2 xmms xv zlib gdbm berkdb slang readline arts tetex svga java guile X sdl gpm tcpd pam libwww ssl perl python esd imlib oggvorbis gtk qt kde motif opengl mozilla -gnome" COMPILER="gcc3" CHOST="i586-pc-linux-gnu" CFLAGS="-march=k6-3 -mmmx -m3dnow -Os -pipe" CXXFLAGS="-march=k6-3 -mmmx -m3dnow -Os -pipe" ACCEPT_KEYWORDS="x86" MAKEOPTS="-j2" AUTOCLEAN="yes" SYNC="rsync://rsync.gentoo.org/gentoo-portage" FEATURES="sandbox ccache" *** NOTE *** same thing happens with "-march=i586"
It may be that any application that uses svgalib has this problem. For example, the program 'fun', which is one of the programs in the svgalib demo directory, has exactly the same problem as zgv -- it segfaults if X11 is running but not if X11 is not running. [wdbh - 13sep02]
could you try this with media-libs/svgalib-1.9.17-r3?
> could you try this with media-libs/svgalib-1.9.17-r3? Thank you for this suggestion. It seems to have fixed the problem (whatever it was). Should I now mark this "bug" as fixed?
My preceding comment needs to be amended because I only ran the svgalib demo program ('fun') logged in as root. Logged in as user, I get this error message: svgalib: Cannot open /dev/svga Permissions on /dev/svga and /dev/svga_helper are set as follows: lr-xr-xr-x 1 root root 13 Dec 31 1969 /dev/svga -> svga_helper/0 drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/svga_helper/ It is not obvious to me why these /dev entries should be dated "Dec 31 1969" while all the others are dated "Sep 28" (today): [gonzo]~/stage/issues/svgalib $ ls -ald /dev/* | grep "Dec 31" drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/cdroms/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/cpu/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/cua/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/discs/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/floppy/ crw-rw-rw- 1 root root 1, 7 Dec 31 1969 /dev/full drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/ide/ crw-r----- 1 root root 1, 2 Dec 31 1969 /dev/kmem crw-r----- 1 root root 1, 1 Dec 31 1969 /dev/mem drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/misc/ crw-rw-rw- 1 root root 1, 3 Dec 31 1969 /dev/null crw-rw-rw- 1 root root 195, 0 Dec 31 1969 /dev/nvidia0 crw-rw-rw- 1 root root 195, 255 Dec 31 1969 /dev/nvidiactl crw-r----- 1 root root 1, 4 Dec 31 1969 /dev/port crw------- 1 root root 108, 0 Dec 31 1969 /dev/ppp drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/printers/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/pts/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/pty/ crw-r--r-- 1 root root 1, 8 Dec 31 1969 /dev/random drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/scsi/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/sound/ lr-xr-xr-x 1 root root 13 Dec 31 1969 /dev/svga -> svga_helper/0 drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/svga_helper/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/tts/ crw-rw-rw- 1 root root 5, 0 Dec 31 1969 /dev/tty crw-r--r-- 1 root root 1, 9 Dec 31 1969 /dev/urandom drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/usb/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/vc/ drwxr-xr-x 1 root root 0 Dec 31 1969 /dev/vcc/ crw-rw-rw- 1 root root 1, 5 Dec 31 1969 /dev/zero wdbh
no idea...
I think the problem may be/have been an "accidental" disappearance of /dev/svga and /dev/svga_helper/[0-9] Today, after getting a "can't open /dev/svga" message, I noticed they were missing, so I re-emerged /usr/portage/media-libs/svgalib/svgalib-1.9.17-r3.ebuild This did not immediately recreate them but they were back as soon as I ran zgv: [root]/dev $ ls -ald svga svga_helper svga_helper/* lr-xr-xr-x 1 root root 13 Dec 31 1969 svga -> svga_helper/0 drwxr-xr-x 1 root root 0 Dec 31 1969 svga_helper/ crwxr--r-- 1 root root 209, 0 Dec 31 1969 svga_helper/0 crwxr--r-- 1 root root 209, 1 Dec 31 1969 svga_helper/1 crwxr--r-- 1 root root 209, 2 Dec 31 1969 svga_helper/2 crwxr--r-- 1 root root 209, 3 Dec 31 1969 svga_helper/3 crwxr--r-- 1 root root 209, 4 Dec 31 1969 svga_helper/4 crwxr--r-- 1 root root 209, 5 Dec 31 1969 svga_helper/5 crwxr--r-- 1 root root 209, 6 Dec 31 1969 svga_helper/6 crwxr--r-- 1 root root 209, 7 Dec 31 1969 svga_helper/7 and AFAICT zgv works right for all users.
