Testing Status

Bugs

  • Tracking the numerous gcc bugs at ?DebianM68kGcc.

  • mathinline is glibc (libc6-dev), 4.0.2-3 (20051109)
    • debian #340871 on libc6-dev (trivial case in report)
    • > /usr/include/bits/mathinline.h:128: error: declaration of 'double atan(double)' throws different exceptions

    • workaround: drop to less than -O1 or drop -pedantic (so USE_EXTERN_INLINES doesn't get defined)

    • pkgs: slgsl_0.5.2-1, php4-vpopmail_4.3.4-5.4.4+2, libgig_2.0.d2-1, highlight_2.4.2-1, blackbox_0.70.0-5

Need Investigation and Bugs Filed

  • gerris_0.6.0-2: m68k, `_FPU_MASK_ZM'
  • pnet_0.6.12-5: m68k, segfaults
  • vtk_4.4.2-8: m68k, throwing an instance of 'std::logic_error'
  • pike7.2_7.2.580-4: m68k, floating point exception
  • ecj-bootstrap_3.1.1-3.1: m68k&hppa, Can't find 'java.lang'

  • imapcopy_1.01-1: not-for-us but why?
  • ree_1.3-1: not in arch list (why no longer not-for-us?)

xargs (dh_fixperms)

  • Looks something like

{{{> > dh_fixperms > > chown: cannot access > > `dedebian/libcommoncpp2-dev/usr/include/cc++2/cc++/common.h': No such file > > or directory chown: cannot access `TERM=unknown': No such file or directory > > dh_fixperms: command returned error code}}}

  • The offending command in dh_fixperms is find debian/caudium -print0 2>/dev/null | xargs -0r chown --no-dereference 0:0, with xargs being the culprit

  • Packages known to fail: libcommoncpp2_1.3.19-1, caudium_2:1.4.7-5, mozilla_2:1.7.11-1, openssl097_0.9.7g-4, exiv2_0.7-9.1, pike7.6_7.6.53-1, tex4ht_20051130-1, craft_3.5-11

  • Workaround: build under kernel 2.4 or better
  • debian bug #336461 (findutils/xargs) seems suspiciously similar

linux-2.6

  • InitrdReplacementOptions need to be sorted out for 2.6.14+

  • klibc needs porting, see bug #[http://bugs.debian.org/334917 334917], for initramfs.

  • mac support, especially adb (can't d-i without it)
  • atari is missing support for framebuffer. Only one memory chunk can be used. Patches from linux-m68k needed for this.
  • How to build a cross-compiler for kernel building: http://people.debian.org/~cts/debian-m68k/cross-compile/

  • Kars de Jongk ported new 53c700 SCSI driver (NCR chip for *VME and Amiga (?WarpEngine, A4000T/A4091)) for kernel 2.6.14, but patch is waiting for Roman Zippels DMA patch inclusion in main tree. Works on two Amigas on mine (ij)

linux-2.4

  • Atari and Mac SCC serial drivers missing
  • Atari ST-RAM swap code broken

binNMU notes

  • example to register dpkg_1.13.11 for a dpkg_1.13.11+b1 binNMU:

wanna-build -b m68k/build-db -d unstable -m "Rebuild with g++-4.0 for C++ +transition." --binNMU=1 dpkg_1.13.11

  • --binNMU=2 for second binNMU.
  • example to deregister any pending binNMU and return to Installed state:

wanna-build -b m68k/build-db -d unstable --binNMU=0 dpkg_1.13.11
