In the Android system, when compiling the CPP program, the program Link encountered a similar error:
Missing: vtable for _ cxxabiv1 ::__ si_class_type_info
This error occurs because no-rtti can be compiled during the compilation process.
This problem can be solved.
The following content comes from: http://blog.csdn.net/vrix/archive/2009/06/23/4290671.aspx is a good summary.
Among all the android source code, only the top-level directory has a makefile. All other projects call this file for compilation. If you use "showcommands" to output detailed compilation information, you will see a large number of compilation options. In fact, you do not need to do so much. Do the following steps:
- Copy all header files to the include directory of the toolchain to reduce the number of-I (header file search directory) options. For details, see: Native Android C Development: toolchain environment setup.
;
- More Options View $ android_src/build/CORE/Combo/linux-arm.mk
This is a compilation option file prepared for Android. Most projects rely on this file for compilation.
After completing the above two steps, the following are some compilation options I have compiled:
- Compile a common C file. cflags is as follows:
Cflags =-O2-include androidconfig. hcflags + =-msoft-float-FPIC/-ffunction-sections/-funwind-tables/-fstack-Protector/-fno-short-enums
- Compile a common CPP file. cxxflags is as follows (compared with cflags, only several bold options are added ):
Cflags =-O2-include androidconfig. hcflags + =-msoft-float-FPIC/-ffunction-sections/-funwind-tables/-fstack-Protector/-fno-short-enums/-fno-rtti/-fstrict- aliasing/-fno-exceptions/-fomit-frame-pointer
- Executable program Link options (in addition to the following options, you also need to add the libraries required by the project, such as-LM and-lstdc ++ ):
Lib_dir =/cygdrive/e/toolchain/ARM-Eabi/libcrt_objs = $ (lib_dir)/crtbegin_dynamic.o $ (lib_dir)/crtend. O ldflags =-S-nostdlib-bdynamic/ldflags + =-wl,-T, armelf. x/-wl,-dynamic-linker,/system/bin/linker-wl, -- GC-sections/-wl,-Z, nocopyreloc/-LC $ (crt_objs)
- Dynamic library link option (replace libtest. So with your library name during compilation, plus the library required by the project ):
Sdflags =-S-nostdlib/-wl,-soname, libtest. So
/-Wl,-shared,-bsymbolic/-wl,-T, armelf. xsc/-wl, -- GC-sections/-LC-LM
Basically, with these compilation options added, you can write your own makefile to compile the project. I have added these compilation options to successfully compile open-source projects such as SDL, JPEG, and LibPNG, for more compilation options, see $ android_src/build/CORE/Combo/linux-arm.mk
