The config/plugins.m4 was updated recently by commit b879806f2fdd2eca7092d7b854d6cbbbbbd0493b. Various sourceware components configure files were updated except GDB's. I run aclocal and autoconf to update gdb/configure. I'll push it in in one day or two, if no comments. diff --git a/gdb/configure b/gdb/configure index 874922d..0b992ed 100755 --- a/gdb/configure +++ b/gdb/configure @@ -1482,7 +1482,7 @@ Optional Features: --enable-FEATURE[=ARG] include FEATURE [ARG=yes] --enable-maintainer-mode enable make rules and dependencies not useful (and sometimes confusing) to the casual installer - --enable-plugins Enable support for plugins (defaults no) + --enable-plugins Enable support for plugins --disable-largefile omit support for large files --enable-targets=TARGETS alternative target configurations @@ -4090,15 +4090,46 @@ test -n "$target_alias" && # even in directories otherwise not depending on the $plugins option. -# Check whether --enable-plugins was given. + maybe_plugins=no + for ac_header in dlfcn.h +do : + ac_fn_c_check_header_compile "$LINENO" "dlfcn.h" "ac_cv_header_dlfcn_h" "$ac_includes_default +" +if test "x$ac_cv_header_dlfcn_h" = x""yes; then : + cat >>confdefs.h <<_ACEOF +#define HAVE_DLFCN_H 1 +_ACEOF + maybe_plugins=yes +fi + +done + + for ac_header in windows.h +do : + ac_fn_c_check_header_compile "$LINENO" "windows.h" "ac_cv_header_windows_h" "$ac_includes_default +" +if test "x$ac_cv_header_windows_h" = x""yes; then : + cat >>confdefs.h <<_ACEOF +#define HAVE_WINDOWS_H 1 +_ACEOF + maybe_plugins=yes +fi + +done + + + # Check whether --enable-plugins was given. if test "${enable_plugins+set}" = set; then : enableval=$enable_plugins; case "${enableval}" in - yes | "") plugins=yes ;; - no) plugins=no ;; - *) plugins=yes ;; - esac + no) plugins=no ;; + *) plugins=yes + if test "$maybe_plugins" != "yes" ; then + as_fn_error "Building with plugin support requires a host that supports dlopen."
