Title Body

I'm trying to use someone else's Makefile to complile a very simple c++ library. The makefile is as follows: JNIFLAGS=-O2 -pthread -I/usr/lib/jvm/java-6-sun/include -I/usr/lib/jvm/java-6-sun/include/linux all: rm -f ../dist/libUtils.so g++ $(JNIFLAGS) -c -m32 -o com_markets_utils_dates_NativeTime.o com_markets_utils_dates_NativeTime.cpp g++ $(JNIFLAGS) -c -m32 -o DateUtil.o DateUtil.cpp g++ -pthread -m32 -shared -fPIC -o ../dist/libUtils.so DateUtil.cpp g++ -pthread -m32 -shared -fPIC -o ../dist/libNativeTime.so DateUtil.o com_markets_utils_dates_NativeTime.o This compiles fine, but the linker complains: ... /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.1/libstdc++.so when searching for -lstdc++ /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.1/libstdc++.a when searching for -lstdc++ /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.1/libstdc++.so when searching for -lstdc++ /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.1/libstdc++.a when searching for -lstdc++ /usr/bin/ld: cannot find -lstdc++ collect2: ld returned 1 exit status make: *** [all] Error 1 FYI, I am on Ubuntu 9.10 64bit.
