Hello,

After building and installing Emacs Android port with  libxml2 and
ImageMagick, Emacs crashed during startup with such bellow error on logcat
output.

And below are nm out put,

this one is when build with libxml2 only,

nm arm64-v8a/libxml2_emacs.so |grep -i ucnv
                 U UCNV_FROM_U_CALLBACK_STOP_56
                 U UCNV_TO_U_CALLBACK_STOP_56
                 U ucnv_close_56
                 U ucnv_convertEx_56
                 U ucnv_open_56
                 U ucnv_setFromUCallBack_56
                 U ucnv_setToUCallBack_56

and below is when build with libxml2 and ImageMagick7

nm arm64-v8a/libxml2_emacs.so |grep -i ucnv
                 U UCNV_FROM_U_CALLBACK_STOP_64
                 U UCNV_TO_U_CALLBACK_STOP_64

                 U ucnv_open_64
                 U ucnv_setFromUCallBack_64
                 U ucnv_setToUCallBack_64

I think this is caused by a conflict due to static libraries *.a  having
the same name during build.
(not *.o because they are made unique by prefixing path to *.o.)

Thanks,

Po Lu, could you take a look at this one?  Thanks in advance.

If I'm not mistaken, the ImageMagick repository provides its own copy of
libxml2 with dependencies that conflict with those users are directed to
install in java/INSTALL.  Ayanokoji-san, is Emacs compatible with
ImageMagick's libxml2?  (This can be established by verifying that Emacs
continues to detect libxml2 and build after removing the standard
libxml2 from --with-ndk-path.)

Hello, Po-san.

I build Emacs with ImageMagick7 Only.

In this build, I made some modifications to java/INSTALL, bellow .

1. Remove unnecessary hunks
 due to #66506.

2. Add LOCAL_SHARED_LIBRARIES libstdc++ to make/libmagickwand-7.mk
 to avoid Emacs crash(see attachment).

3. Fix typo in original source
 change "echo." to "echo".

In report-emacs-bug(see attachment), it configured with libxml2, but in the
apk's lib/ there is not libxml2.so.

(In the build log, libxml2 was build as static library).

Build script:

Build log(4MB archived log):

I will look into this in a bit, thanks.
