Summary: zimreader on arm: miss-aligned dirent header
Product: openZIM
Version: unspecified
Platform: Other
OS/Version: Linux
Status: NEW
Severity: major
Priority: P5

Patch to correct alignment of the dirent header
-- System Information:
Debian Release: 5.0.2
APT prefers stable
APT policy: (500, 'stable')
Architecture: armel (armv4tl)
Kernel: Linux 2.6.24-20081103.git7172ec57 (PREEMPT)
Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) (ignored: LC_ALL
set to de_DE.UTF-8)
Plattform: openmoko Freerunner
Since the dirent header variable in
zim::std::istream& operator>> (std::istream& in, Dirent& dirent)
is define as char, the compiler chooses 2-byte-alignment. Later
4-byte access will fail on architectures with poor miss-alignment
recovery (see [1]).
Possibly there are further variables to be explicitly alignment.
I only fixed the one that made zimreader fail (see patch).
Note: The patch is gcc-specific, which may not be desired.

Summary: zimreader on arm: cxxtools/m4/asmtype.m4 broken for
arm architecture
Product: openZIM

Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement

Patch for fixing build configuration for arm plattform (cxxtools/m4/asmtype.m4)
Since I couldn't find a bug tracker for cxxtools, i'll submit this bug here.
Sorry, if I cause inconveniences.
-- System Information:
Debian Release: 5.0.2

Patch contains two fixes:
Square brackets in assembler code get eaten by automake. Doubling
helped.
CXXTOOLS_ATOMICITY_ARM needs to be renamed CXXTOOLS_ATOMICITY_GCC_ARM
for make to build atomicity.gcc.arm.cpp.
This has also been tested in an cross-build environment.
