Re: Libreoffice build error[for android]

[di liu]

That's great ! There is no link error when i execute the command 'make
distclean' and make all dynamic files(.so) used to android.But i think i
should spend more time on makefile to make it clear how does the process
work.

Thank you very much for your help.

OK, had I enabled HTML rendering for the email, it would have been clear 
that the '--no-check-certificate' option was actually meant, sorry for 
the noise...

I just modified one file which named "Makefile.fetch" location in root 
dir of libreoffice,But i think this change has nothing to do with this error

below is my change's content
"

ifneq (,$(WGET))
define fetch_Download__wget_command
&& bash -c '$(WGET) --no-check-certificate--progress=dot:mega -Q 0 -P 
"." -l 0 -nd -nH -N --no-use-server-timestamps $1/$2 2>&1 | tee -a 
$(fetch_LOGFILE) && [ $$PIPESTATUS -eq 0 ]'

endef

"
I have added he green color option which used solve certification problem
but I still want to have try with "make distclean"


It's not really clear to me what "he green color option" refers to, but 
if that refers to the change of adding the '--no-check-certificate' 
option for wget, that should actually be unrelated.



I have a another problem:
I have search the undefined method "lo_get_custom_widget_func" and find 
this method is defined dynamic . It's was defined by native-code.py I 
don't know why we're doing this and how it's work
.Could you give me a simple explanation or provide me some documents to 
make it's clear ?


Good point.

I don't know details about this either, but I think the idea is to strip 
down what C++ code to build/include for the mobile apps to reduce the 
size of the library to what's actually needed there.


At last I wonder if I can do that execute "native-code.py" and put the 
result to a new  cpp file and add it to makefile when I still have the 
link error ?


Looking at android/source/Makefile, this is the command used to generate 
the file:


./solenv/bin/native-code.py -j -g core -g writer -g calc -g draw -g 
edit > android/source/native-code.cxx


I have pasted what the output/file looks like for me here:
http://paste.debian.net/1232969/

In case that differs from yours, tracking down what happens inside 
native-code.py might provide insights what's going wrong.

If you have current git master without any local changes and 'make 
distclean' and trying again doesn't work, you could try using a 
different version of the Android NDK, or use LLD as linker instead of 
ld.gold by applying the demo patch at 
https://gerrit.libreoffice.org/c/core/+/130947 and switching to a newer 
NDK; a build here worked with that Gerrit change in place and an 
autogen.input containing this:


--with-distro=LibreOfficeAndroid
--with-android-ndk=/home/michi/Android/Sdk/ndk/22.1.7171670/
--with-android-sdk=/home/michi/Android/Sdk
--with-external-tar=/home/michi/development/libreoffice-external

(At least my experience in the past was that it was a bit tricky to find 
a combination of Android NDK and linker that would work depending on 
architecture and whether this was a release or debug build. But the 
problems I encountered back then were more "fundamental" than the 
"undefined reference" issue you're encountering. Maybe all of the issues 
I had two years ago or so are fixed in newer versions of the toolchain, 
but so far I just stayed with what was working back then...)
