After unsuccessfully trying to fix this issue, I ran make distclean and started over with the previous configure options. After make failed (again at libgcc) I navigated to the gcc dir in the build folder and ran configure. ../../gcc-4.9.1/gcc/configure --prefix=/usr/gcc-4.9 --build=arm-linux-androideabi --host=arm-linux-androideabi --target=arm-linux-androideabi --with-build-libsubdir=/usr/gcc-4.8/sysroot/usr/lib --with-native-system-header-dir=/usr/gcc-4.8/sysroot/usr/include --with-build-sysroot=/usr/gcc-4.8/sysroot --with-sysroot=/usr/gcc-4.8/sysroot LIBS=-ldl LDFLAGS=-Wl,--dynamic-linker=/system/bin/linker -L/usr/gcc-4.8/sysroot/usr/lib The last several lines in the configure result indicate that ldl is still not being picked up as the library containing dlopen; configure still decides 'none needed' I've minimal experience with configure code; how is gcc/configure determining if ldl contains dlopen and how would I run configure and/or specify env variables so that configure picks up ldl? (FYI, I did objdump -tT libdl.so...dlopen is there)
