When we use `--disable-tools` (ie, when we are cross-compiling), ICU
will build the data only if it detects we are cross-compiling.
This make sens until we cross-compiling for wasm.
Wasm output is a script file with the interpreter in the sdk we have
installed. So ICU's configure can run the test binary and so doesn't detect
we are cross-compiling.
So we have to patch ICU Makefile to make it build the ICU data anyway.
ICU is used to:
- List locales (`locales_tree`)
- Get information about those locales in different languages (`lang_tree`)
- Remove accents (`translit`)
Tracing ICU without custom data, we also load `likelySubtags` and
`metadata`. Not sure why and what happen when missing but let's be
conservatives and include them.
cross-gcc-10.3.0-pi_64.tar.gz for 64 bits architecture and armhf
is about 32 bits.
However, we know use a pi 2 and 3 and Stretch only[*] toolchains
[*] To be tested. Maybe the only is for the target compilation but binary
run elsewhere too.
Version 5.2.7 include this commit
https://git.tukaani.org/?p=xz.git;a=commit;h=31d80c6b261b24220776dfaeb8a04f80f80e0a24
With this change, compiling libzim mixed (libzim dynamic and dependencies,
so lzma, statically) fails at libzim linking with a
`src/libzim.so.8.0.1: version node not found for symbol lzma_get_progress@XZ_5.2.2`
error message.
This can be "workaround" by passing `--disable-symbol-versions` to
configure script but then, it is the compilation of kiwix-desktop in
native_dyn which falling with
```
/usr/bin/ld: /usr/lib64/libsystemd.so.0: undefined reference to `lzma_code@XZ_5.0'
/usr/bin/ld: /usr/lib64/libsystemd.so.0: undefined reference to `lzma_end@XZ_5.0'
/usr/bin/ld: /usr/lib64/libsystemd.so.0: undefined reference to `lzma_stream_decoder@XZ_5.0'
/usr/bin/ld: /usr/lib64/libxml2.so.2: undefined reference to `lzma_auto_decoder@XZ_5.0'
/usr/bin/ld: /usr/lib64/libxml2.so.2: undefined reference to `lzma_properties_decode@XZ_5.0'
```
Probably because some native dependencies (Qt ?) use versionned symbols.
This have to be fixed somehow but until then, let's go back to 5.2.6
`icu4c_wasm.patch` is build by :
- Copying config.sub from liblzma source as new version of config.sub there
knows about wasm architecture.
- Copying `mh-linux` on `mh-unknown` as specified in (origin) `mh-unknown`.
This is because icu4c configure doesn't detect `emscripten` platform and
"fallback" to `mh-unknown`.
Aria2 is a special case. We actually don't really need to compile it.
kiwix-desktop through libkiwix use the aria2c binary but we always
use (package) the system binary or a prebuild release.
And we don't cross compile kiwix-desktop to windows, so we don't need
aria2c neither.
The sub-directory `android-kiwix-lib-publisher` has not been renamed.
We plan to move this code in another repository anyway.
It is better for now to use the existing name instead of change the
directory.
