• usertag gcc-40 - gcc-4.0-specific problems
• usertag needs-port - needs porting work (e.g., klibc, parted, pnet)
• usertag pending - patch/solution accepted

linux-2.6

• 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/

linux-2.4

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

gcc triage

• check against latest sid gcc-4.0
• check against latest sid gcc-3.4

• bug is listed in debian bts http://bugs.debian.org/cgi-bin/pkgreport.cgi?src=gcc-4.0

• bug is listed upstream http://gcc.gnu.org/bugzilla/

• check against gcc-snapshot (if it's more recent)
• check against gnu compiler (w/o debian patches)
• update and close old bug reports

Investigate and File Bugs

• strace_4.5.12-1: m68k, error: `NR_exit_group

• vtk_4.4.2-8: m68k, throwing an instance of 'std::logic_error'
• guile-1.6_1.6.7-1.1: m68k, failed self test, old compiler
• pike7.2_7.2.580-4: m68k, floating point exception
• gerris_0.6.0-2: m68k, `_FPU_MASK_ZM'
• nullmailer_1:1.00-3: m68k, undefined reference to `main', 4.0.2-2

• ecj-bootstrap_3.1.1-3.1: m68k&hppa, Can't find 'java.lang'

• gjdoc_0.7.6-1:m68k, gcj-wrapper-4.0 failed (antlr or java-gcj-compat?)
• imapcopy_1.01-1: not-for-us but why?
• ree_1.3-1: not in arch list (why no longer not-for-us?)
• pnet_0.6.12-5: m68k, segfaults

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, digikamimageplugins_0.7.4-4, drscheme_1:209-8, caudium_2:1.4.7-5, libclass-methodmaker-perl_2.07-2, mozilla_2:1.7.11-1, openssl097_0.9.7g-4, ncurses_5.5-1, sympa_4.1.5-7, pike7.4_7.4.325-2, mpqc_2.2.3-2
• Workaround: build under kernel 2.4 or better?
• bug #336461 (findutils/xargs) seems suspiciously similar
• Try rebuilding fileutils and debhelper?
