hi,expert i use OpenCV-2.4.8-android-sdk and android-ndk-r8-crystax-1 to build my .so lib for android project.when i compile in non-static mode,i can success.however,when i compile in static mode that is add OPENCV_LIB_TYPE:=STATIC in android.mk i find errors as follow: "Compile++ thumb : SmokeDetect <= SmokeDetect.cpp SharedLibrary : libSmokeDetect.so D:/android-ndk-r8-crystax-1/toolchains/arm-linux-androideabi-4.6/prebuilt/windows/bin/../lib/gcc/arm-linux /ld.exe: ../../../sdk/native/jni/../3rdparty/libs/armeabi/libIlmImf.a(ImfStdIO.cpp.o): in function Imf::St t._ZN3Imf11StdIFStream5seekgEy+0x16): error: undefined reference to 'std::istream::seekg(std::fpos<mbstate d:="" android-ndk-r8-crystax-1="" toolchains="" arm-linux-androideabi-4.6="" prebuilt="" windows="" bin="" ..="" lib="" gcc="" arm-linux="" ld.exe:="" ..="" ..="" ..="" sdk="" native="" jni="" ..="" 3rdparty="" libs="" armeabi="" libilmimf.a(imfstdio.cpp.o):="" in="" function="" imf::st="" t._zn3imf11stdosstream5seekpey+0x18):="" error:="" undefined="" reference="" to="" 'std::ostream::seekp(std::fpos<mbstate="" d:="" android-ndk-r8-crystax-1="" toolchains="" arm-linux-androideabi-4.6="" prebuilt="" windows="" bin="" ..="" lib="" gcc="" arm-linux="" ld.exe:="" ..="" ..="" ..="" sdk="" native="" jni="" ..="" 3rdparty="" libs="" armeabi="" libilmimf.a(imfstdio.cpp.o):="" in="" function="" imf::st="" t._zn3imf11stdofstream5seekpey+0x16):="" error:="" undefined="" reference="" to="" 'std::ostream::seekp(std::fpos<mbstate="" collect2:="" ld="" returned="" 1="" exit="" status="" make:="" <em="">* [D:/OpenCV-2.4.8-android-sdk/samples/smokedetect//obj/local/armeabi/libSmokeDetect.so] Error 1

is there bugs in opencv2.4.8?why are there many errors when compile,link in opencv sdk? how can i resolve it?any light would be appreciated.thanks any comment.
