I'm cross-compiling libcurl with ARM toolchain provided by android NDK r8. My
output libcurl.so has an undefined symbo __cxa_begin_cleanup. Use command
"readelf -s" can find it :
168: 00000000 0 NOTYPE WEAK DEFAULT UND __cxa_begin_cleanup
When creating my executable with libcurl.so and some other libraries, a link
error reported:
hidden symbol __cxa_begin_cleanup in libstdc++ is referenced by DSO.
This symbol in libstdc++.so is a hidden symbol , so linker can not resolve the
undefined symbol in libcurl.so .
I check other share libraries. Some of them contain this symbol also, but it's
not undefined symbol in those libraries. They seems copy that symbol's
implementation to themselves from libstdc++, while libcurl does not copy.
My command to produce libcurl.so is :
arm-linux-androideabi-gcc -shared .libs/file.o (and other .o files)
-L/opt/android-ndk-r8-standalone/arm-linux-androideabi/libs/armeabi-v7a
-L/opt/android-ndk-r8-standalone/sysroot/usr/lib -lz -mandroid -march=armv7-a
-mfloat-abi=softfp -mfpu=vfp -mthumb -Wl,-soname -Wl,libcurl.so.5 -o
.libs/libcurl.so.5.2.0
I'v tried adding "-nostdlib -lgcc" to the command, but produce same result.
Could anybody help me to resolve this issue. It has blocked me for many days.
Thanks in advance.
