Re: Fwd: Application crashes with bootstrapping exception built on libreoffice-6-3-2 branch

["TheIstere ." <lexboss777@xxxxxxxxx>]

Hello,

I have just tried it out with master branch. As before I have compiled it for aarch64 (arm64-v8a).

As like with libreoffice-6-3-2 branch some fixes were required to compile it:

1. Fixing nss error: "checking host system type... Invalid configuration `aarch64-unknown-linux-android': machine `aarch64-unknown-linux' not recognized"

cp config.guess workdir_for_build/UnpackedTarball/nss/nspr/build/autoconf/config.guess
cp config.guess workdir/UnpackedTarball/nss/nspr/build/autoconf/config.guess
cp config.sub workdir_for_build/UnpackedTarball/nss/nspr/build/autoconf/config.sub
cp config.sub workdir/UnpackedTarball/nss/nspr/build/autoconf/config.sub

2. Missing types when compiling bridge.

I copied share.hxx file from gcc3_linux_x86-64 directory and included in two files (uno2cpp.cxx and abi.cxx) #include "share.hxx"

3. nss again:

added directive #define NS_PTR_GT_32 in:
./workdir_for_build/UnpackedTarball/nss/nss/lib/freebl/drbg.c
./workdir/UnpackedTarball/nss/nss/lib/freebl/drbg.c

4. Neon errors when compiling libpng like this:

error: undefined reference to 'png_riffle_palette_neon'

error: undefined reference to 'png_do_expand_palette_rgba8_neon'

undefined reference to 'png_init_filter_functions_neon'

../Bootstrap/Makefile.shared:60: recipe for target 'obj/local/arm64-v8a/liblo-native-code.so' failed
make[2]: *** [obj/local/arm64-v8a/liblo-native-code.so] Error 1

So, I disabled neon optimisations:

Changing the line number 130 in pngpriv.h form
define PNG_ARM_NEON_OPT 2
to
define PNG_ARM_NEON_OPT 0.

Then I have got an apk and when I am trying to open a document the crash happens. The first time I try it libreoffice shows loader for a long time and then crashes, after that when opening a documents it crashes almost immediately.

I have created a bug-report here https://bugs.documentfoundation.org/show_bug.cgi?id=127781 

Is there any plans to make libreoffice working on aarch64 ? Because Google Play now requires that all apps have also 64-bit versions of used native libraries.

although only for x86_64

aarch64 needs at least a patch to nss - it's configure/auto-detection
stuff doesn't bother checking for aarch64, so resets cpu arch to arm
otherwise, resulting in incompatible libs.
And I guess it also will need some related fixes in bridges, similar
to how it was done for arm (didn't look into that yet).

But to also state it: There is no point in building the android
version from a branch, it is best to use master for that. - that is
the only branch that gets built by the only tinderbox we have for it,
and the only branch where anything android related is done, there are
no cherry-picks or backports to release branches for android stuff..

ciao
Christian
