Hi,
I wonder if there anybody has tried my solution,for I've got no feedback
till now?
Now,because the deps of spicec-gtk are so MANY,thus use the static libs
shall be economic,
hence the new snappy/libspicec.so:
*# arm-eabi-readelf -d libspicec.so
Dynamic section at offset 0x38bf98 contains 22 entries:
Tag Type Name/Value
0x00000001 (NEEDED) Shared library: [libdl.so]
0x00000001 (NEEDED) Shared library: [libstdc++.so]
0x00000001 (NEEDED) Shared library: [libz.so]
0x00000001 (NEEDED) Shared library: [libc.so]
0x00000001 (NEEDED) Shared library: [libcrypto.so]
0x00000001 (NEEDED) Shared library: [libssl.so]
0x00000001 (NEEDED) Shared library: [libm.so]
...*
all the deps of libspicec.so can be found in android system,the other deps
such as glibs are all built staticaly into libspicec.
But I got another bug, when staticaly linked,libcrypto and libssl will
spit SEGFAULT in running(the same as when using the shared ones in Android
system),but my self-compiled shared libssl and libcrypto work well, why?
Does this mean there is some buggy use in
spice-channel.c :spice_channel_send_auth()? The static or system's shared
libssl/libcrypto always die at RSA_size() or BIO_free() in
spice_channel_send_auth()).
Would Somebody do a try or check on this?
I'm keen on that.
Rgrds.
