1. 下载MinGW32到本地,以便能够使用gcc编译器以及和linux相关的一些库文件。
2. 由于libmemcached的测试程序需要依赖memcached.exe本身,如果需要将memcached在win32下编译,需要修改部分和socket相关的code,而又考虑到仅仅是测试用例需要,因此决定通过修改configure(由autoconfig用于生成makefile的配置信息检查的shell文件)文件,以使libmemcached的编译不在依赖memcached。
3. 为了完成第二步,需要手工修改configure文件,将如下shell代码注释掉,以便在执行./configure的时候不再将memcached.exe作为一个必须的配置检查条件。注: 在该文件中搜索--with-memcached即可找到以下code
# Check whether --with-memcached was given.
#if test "${with_memcached+set}" = set; then :
# withval=$with_memcached; ac_cv_with_memcached="$withval"
#else
# ac_cv_with_memcached=memcached
#fi
# just ignore the user if --without-memcached is passed.. it is
# only used by make test
# if test "x$withval" = "xno"; then :
#
# ac_cv_with_memcached=memcached
# MEMC_BINARY=memcached
#else
#
# if test -f "$withval"; then :
#
# ac_cv_with_memcached=$withval
# MEMC_BINARY=$withval
#
#else
#
# Extract the first word of "$ac_cv_with_memcached", so it can be a program name with args.
#set dummy $ac_cv_with_memcached; ac_word=$2
#{ $as_echo "$as_me:${as_lineno-$LINENO}: checking for $ac_word" >&5
#$as_echo_n "checking for $ac_word... " >&6; }
#if test "${ac_cv_path_MEMC_BINARY+set}" = set; then :
# $as_echo_n "(cached) " >&6
#else
# case $MEMC_BINARY in
# [\\/]* | :[\\/]*)
# ac_cv_path_MEMC_BINARY="$MEMC_BINARY" # Let the user override the test with a path.

# ac_cv_path_MEMC_BINARY="$as_dir/$ac_word$ac_exec_ext"
# $as_echo "$as_me:${as_lineno-$LINENO}: found $as_dir/$ac_word$ac_exec_ext" >&5
# break 2

#MEMC_BINARY=$ac_cv_path_MEMC_BINARY
#if test -n "$MEMC_BINARY"; then
# { $as_echo "$as_me:${as_lineno-$LINENO}: result: $MEMC_BINARY" >&5
#$as_echo "$MEMC_BINARY" >&6; }
#else

#$as_echo "no" >&6; }
#fi
#
#
# if test "x$MEMC_BINARY" = "xno"; then :
# as_fn_error $ "\"could not find memcached binary\"" "$LINENO" 5
#fi

#fi
#cat >>confdefs.h <<_ACEOF
#define MEMCACHED_BINARY "$MEMC_BINARY"
#_ACEOF
4. 从以上代码中可以发现MEMCACHED_BINARY宏是需要在程序中用到的,此时需要手工将用到该宏的地方进行修改,如下: (请参见libtest/server.c,同时搜索字符串MEMCACHED_BINARY)
if (x == 0)
{
// 原有代码
// snprintf(buffer, sizeof(buffer), "%s -d -P %s -t 1 -p %u -U %u -m 128",
// MEMCACHED_BINARY, construct->pid_file[x], construct->port[x], construct->port[x]);
// 修改为
snprintf(buffer, sizeof(buffer), "-d -P %s -t 1 -p %u -U %u -m 128",
construct->pid_file[x], construct->port[x], construct->port[x]);
}
else
{
// 原有代码
// snprintf(buffer, sizeof(buffer), "%s -d -P %s -t 1 -p %u -U %u",
// MEMCACHED_BINARY, construct->pid_file[x], construct->port[x], construct->port[x]);
// 修改为
snprintf(buffer, sizeof(buff
