在安装sdcv的时候,编译显示错误是"checking for zlibversion in -lz... no
configure: error:zlib not found"
可是我装了zlib-1.2.2还是不行.编译结果还是同上面一样.
于是我打开configure文件有关于zlib的程序,如下,麻烦高手帮我解释一下,这段程序大概什么意思,有什么用的?
echo "$as_me:$LINENO: checking for zlibVersion in -lz" >&5
echo $ECHO_N "checking for zlibVersion in -lz... $ECHO_C" >&6
if test "${ac_cv_lib_z_zlibVersion+set}" = set; then
echo $ECHO_N "(cached) $ECHO_C" >&6
else
ac_check_lib_save_LIBS=$LIBS
LIBS="-lz $LIBS"
cat >conftest.$ac_ext <<_ACEOF
/* confdefs.h. */
_ACEOF
cat confdefs.h >>conftest.$ac_ext
cat >>conftest.$ac_ext <<_ACEOF
/* end confdefs.h. */
/* Override any gcc2 internal prototype to avoid an error. */
#ifdef __cplusplus
extern "C"
#endif
/* We use char because int might match the return type of a gcc2
builtin and then its argument prototype would still apply. */
char zlibVersion ();
int
main ()
{
zlibVersion ();
;
return 0;
_ACEOF
rm -f conftest.$ac_objext conftest$ac_exeext
if { (eval echo "$as_me:$LINENO: \"$ac_link\"") >&5
(eval $ac_link) 2>conftest.er1
ac_status=$?
grep -v '^ *+' conftest.er1 >conftest.err
rm -f conftest.er1
cat conftest.err >&5
echo "$as_me:$LINENO: \$? = $ac_status" >&5
(exit $ac_status); } &&
{ ac_try='test -z "$ac_cxx_werror_flag"
|| test ! -s conftest.err'
{ (eval echo "$as_me:$LINENO: \"$ac_try\"") >&5
(eval $ac_try) 2>&5
ac_status=$?
echo "$as_me:$LINENO: \$? = $ac_status" >&5
(exit $ac_status); }; } &&
{ ac_try='test -s conftest$ac_exeext'
{ (eval echo "$as_me:$LINENO: \"$ac_try\"") >&5
(eval $ac_try) 2>&5
ac_status=$?
echo "$as_me:$LINENO: \$? = $ac_status" >&5
(exit $ac_status); }; }; then
ac_cv_lib_z_zlibVersion=yes
else
echo "$as_me: failed program was:" >&5
sed 's/^/| /' conftest.$ac_ext >&5
ac_cv_lib_z_zlibVersion=no
fi
rm -f conftest.err conftest.$ac_objext \
conftest$ac_exeext conftest.$ac_ext
LIBS=$ac_check_lib_save_LIBS
fi
echo "$as_me:$LINENO: result: $ac_cv_lib_z_zlibVersion" >&5
echo "${ECHO_T}$ac_cv_lib_z_zlibVersion" >&6
if test $ac_cv_lib_z_zlibVersion = yes; then
LIBS="$LIBS -lz"
else
{ { echo "$as_me:$LINENO: error: zlib not found" >&5
echo "$as_me: error: zlib not found" >&2;}
{ (exit 1); exit 1; }; }
fi
十分感谢呀!!!!!!!!!!!!!!!
