回复 2# lenky0401
这是./configure文件中的信息。- if ac_fn_c_try_link "$LINENO"; then :
- ac_cv_lib_dl_dlopen=yes
- else
- ac_cv_lib_dl_dlopen=no
- fi
- rm -f core conftest.err conftest.$ac_objext \
- conftest$ac_exeext conftest.$ac_ext
- LIBS=$ac_check_lib_save_LIBS
- fi
- { $as_echo "$as_me:${as_lineno-$LINENO}: result: $ac_cv_lib_dl_dlopen" >&5
- $as_echo "$ac_cv_lib_dl_dlopen" >&6; }
- if test "x$ac_cv_lib_dl_dlopen" = xyes; then :
- cat >>confdefs.h <<_ACEOF
- #define HAVE_LIBDL 1
- _ACEOF
- LIBS="-ldl $LIBS"
- else
- { { $as_echo "$as_me:${as_lineno-$LINENO}: error: in \`$ac_pwd':" >&5
- $as_echo "$as_me: error: in \`$ac_pwd':" >&2;}
- as_fn_error $? "dyload need libdl
- See \`config.log' for more details" "$LINENO" 5; }
- fi
- fi
复制代码 这个地if ac_fn_c_try_link- ac_fn_c_try_link ()
- {
- as_lineno=${as_lineno-"$1"} as_lineno_stack=as_lineno_stack=$as_lineno_stack
- rm -f conftest.$ac_objext conftest$ac_exeext
- if { { ac_try="$ac_link"
- case "(($ac_try" in
- *\"* | *\`* | *\\*) ac_try_echo=\$ac_try;;
- *) ac_try_echo=$ac_try;;
- esac
- eval ac_try_echo="\"\$as_me:${as_lineno-$LINENO}: $ac_try_echo\""
- $as_echo "$ac_try_echo"; } >&5
- (eval "$ac_link") 2>conftest.err
- ac_status=$?
- if test -s conftest.err; then
- grep -v '^ *+' conftest.err >conftest.er1
- cat conftest.er1 >&5
- mv -f conftest.er1 conftest.err
- fi
- $as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5
- test $ac_status = 0; } && {
- test -z "$ac_c_werror_flag" ||
- test ! -s conftest.err
- } && test -s conftest$ac_exeext && {
- test "$cross_compiling" = yes ||
- $as_test_x conftest$ac_exeext
- }; then :
- ac_retval=0
- else
- $as_echo "$as_me: failed program was:" >&5
- sed 's/^/| /' conftest.$ac_ext >&5
- ac_retval=1
- fi
- # Delete the IPA/IPO (Inter Procedural Analysis/Optimization) information
- # created by the PGI compiler (conftest_ipa8_conftest.oo), as it would
- # interfere with the next link command; also delete a directory that is
- # left behind by Apple's compiler. We do this before executing the actions.
- rm -rf conftest.dSYM conftest_ipa8_conftest.oo
- eval $as_lineno_stack; ${as_lineno_stack:+:} unset as_lineno
- as_fn_set_status $ac_retval
- }
