Hello, I have a problem while cross-compiling a native sh4 compiler. To be exact, I'm building on x86_64 a linux native sh4 compiler. My configure is :
configure *--host=sh4-linux* *--build=x86_64-unknown-linux- gnu* --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/share --mandir=/usr/share/man --infodir=/usr/share/info *--target=sh4-linux* --enable-target-optspace --enable-languages=c,c++ --enable-threads=posix --enable-nls --enable-c99 --enable-long-long --with-system-zlib --enable-shared --disable-libgomp --disable-sjlj-exceptions --with-pkgversion=GCC --with-bugurl=https://bugzilla.stlinux.com --disable-libstdcxx-pch --disable-libitm --enable-multilib --disable-multi-sysroot --with-multilib-list=m4-nofpu --enable-lto --with-mpc=/tmp/69328.tmpdir/ stlinux-shared/distro-sh4/STLinux-2.4/devkit/sh4/target --with-gmp=/tmp/69328.tmpdir/stlinux-shared/distro-sh4/STLinux-2.4/devkit/sh4/target --with-mpfr=/tmp/69328.tmpdir/stlinux-shared/distro-sh4/STLinux-2.4/devkit/sh4/target --without-ppl --enable-symvers=gnu --enable-__cxa_atexit In the configuration phase, I can see : if test x$host != x$target || test "x$TARGET_SYSTEM_ROOT" != x; then if test "x$with_headers" != x; then target_header_dir=$with_headers elif test "x$with_sysroot" = x; then target_header_dir="${exec_prefix}/${target_noncanonical}/sys-include" elif test "x$with_build_sysroot" != "x"; then target_header_dir="${with_build_sysroot}${native_system_header_dir}" elif test "x$with_sysroot" = xyes; then target_header_dir="${exec_prefix}/${target_noncanonical}/sys-root${native_system_header_dir}" else target_header_dir="${with_sysroot}${native_system_header_dir}" fi else target_header_dir=${native_system_header_dir} fi [...] if test -f $target_header_dir/sys/sdt.h; then AC_DEFINE(HAVE_SYS_SDT_H, 1, [Define if your target C library provides sys/sdt.h]) fi In my case, the $host and $target are the same (sh4-linux), the target_header_dir is then assigned to /usr/include, which is not the $target_header_dir but the "host system header dir"). Later, the configure erroneously checks the existence of a target header dir. the HAVE_SYS_SDT_H defined is set while it doesn't exist in the target headers. I have the feeling that the target_header_dir is not properly set. I believe the test should be between $build and the $target. What do you think about : -if test x$host != x$target || test "x$TARGET_SYSTEM_ROOT" != x; then +if test x$build != x$target || test "x$TARGET_SYSTEM_ROOT" != x; then Then, beside that change I might also need to add a --with-sysroot to my configure command, but looking at the gnu install pages, i m not sure ... Please advice. Thanks Laurent
