If I cross build GDB for arm-none-linux-gnueabi(hf) or aarch64-none-linux-gnu with below configuration: ../binutils-gdb/configure --enable-64-bit-bfd --enable-targets=arm-none-eabi,arm-none-linux-gnueabihf,armeb-none-eabi,armeb-none-linux-gnueabihf --target=arm-none-linux-gnueabihf --disable-doc --disable-gdbtk --disable-nls --disable-tui --without-python --without-x ... Yes zlib is built in build directory, and -lz is added on link command line of as/gdb/sim, but option "-L/home/.../obj/binutils/zlib" is only added for binutils program, not GDB/SIM. It seems to me gdb/sim still use the system z library, rather than the built one. The readelf -dl gives below information: 0x0000000000000001 (NEEDED) Shared library: [libdl.so.2] 0x0000000000000001 (NEEDED) Shared library: [libtinfo.so.5] 0x0000000000000001 (NEEDED) Shared library: [libz.so.1] 0x0000000000000001 (NEEDED) Shared library: [libm.so.6] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] We also do cross build with "build != host == target". In this scenario, neither "-lz" and "-L..." option is't added in link command line for gdb/sim. And I got below error message: ../bfd/libbfd.a(compress.o): In function `decompress_contents': /home/binche01/work/systematic_testing/2015/workspace/build/bfd/../../binutils-gdb.old/bfd/compress.c:46: undefined reference to `inflateInit_' /home/binche01/work/systematic_testing/2015/workspace/build/bfd/../../binutils-gdb.old/bfd/compress.c:56: undefined reference to `inflateReset' /home/binche01/work/systematic_testing/2015/workspace/build/bfd/../../binutils-gdb.old/bfd/compress.c:53: undefined reference to `inflate' /home/binche01/work/systematic_testing/2015/workspace/build/bfd/../../binutils-gdb.old/bfd/compress.c:58: undefined reference to `inflateEnd' ../bfd/libbfd.a(compress.o): In function `bfd_compress_section_contents': /home/binche01/work/systematic_testing/2015/workspace/build/bfd/../../binutils-gdb.old/bfd/compress.c:79: undefined reference to `compressBound' /home/binche01/work/systematic_testing/2015/workspace/build/bfd/../../binutils-gdb.old/bfd/compress.c:85: undefined reference to `compress' collect2: error: ld returned 1 exit status Thanks, bin > > -- > H.J.
