这看起来已经存在多年了-但是我找不到与Mac相关的最新信息，仅安装CPAN模块DBD :: mysql就已经有好几天了。

这是我正在使用的cpanm行。
sudo cpanm --configure-args="--libs='-L/usr/local/opt/openssl/lib -L/usr/local/lib -L/usr/local/Cellar/mysql/8.0.12/lib' --cflags='-I/usr/local/opt/openssl/include -I/usr/local/include/mysql -I/usr/local/Cellar/mysql/8.0.12/include/mysql'" DBD::mysql
我已经用Homebrew和其他所有东西安装了mysql。我什至已经将几个库复制到系统目录中-但是似乎没有人想要让此cpan模块安装和运行。
编辑：此行之后的添加。 让我们尝试手工制作包装
sudo perl Makefile.PL --libs="-L/usr/local/opt/openssl/lib -L/usr/local/lib -L/usr/local/Cellar/mysql/8.0.12/lib -lssl -lcrypto"
制造的结果。看起来不错。我在这里没有看到错误。显然所有库都可以编译。
zeus:DBD-mysql-4.048-0 robert$ sudo perl Makefile.PL --libs="-L/usr/local/opt/openssl/lib -lssl -lcrypto -L/usr/local/lib -L/usr/local/Cellar/mysql/8.0.12/lib"
I will use the following settings for compiling and testing:
cflags (mysql_config ) = -I/usr/local/Cellar/mysql/8.0.12/include/mysql
embedded (guessed ) =
libs (User's choice) = -L/usr/local/opt/openssl/lib -lssl -lcrypto -L/usr/local/lib -L/usr/local/Cellar/mysql/8.0.12/lib
mysql_config (Users choice ) = mysql_config
nocatchstderr (default ) = 0
nofoundrows (default ) = 0
nossl (default ) = 0
testdb (User's choice) = test
testhost (default ) =
testpassword (default ) =
testport (default ) =
testsocket (default ) =
testuser (User's choice) = root
To change these settings, see 'perl Makefile.PL --help' and
'perldoc DBD::mysql::INSTALL'.
Checking if libs are available for compiling...
Looks good.
Checking if your kit is complete...
Looks good

现在让我们看看 make 是否有效。
看起来不错。 1条关于WIDEST_UTYPE的警告，但这只是一条警告...
然后，制作mysql.bundle
chmod 755 blib/arch/auto/DBD/mysql/mysql.bundle

好，现在是一项重大考验。 进行测试。

...就在那里。同样的错误。现在，我还尝试了MariaDB-结果相同，尽管错误消息略有不同。
我在这里想念什么。
答案 0 :(得分：6)
So I finally found it. Of course, it was locating the libraries and include files properly.
So I went into the cpan directory on my system
/Users/robert/.cpan/build/DBD-mysql-4.048-0
After checking just where the brew installations were for both openssl and mysql, I woke up.
sudo perl Makefile.PL --libs="-L/usr/local/opt/openssl/lib -lssl -lcrypto -L/usr/local/lib -L/usr/local/Cellar/mysql/8.0.12/lib -lmysqlclient"
Now. that worked because after looking in the mysaql lib directory, I see that the library is 'mysqlclient' and not mysql. As you see above.
Now that worked doing the Makefile.PL thing as above.
Then 'make' worked. As above. Not showing any errors... as above
Then sudo make test worked - this time.
All tests successful.
Files=73, Tests=9, 11 wallclock secs ( 0.24 usr 0.15 sys + 8.25 cusr 1.23 csys = 9.87 CPU)
Result: PASS
Finally - make install. Worked
zeus:DBD-mysql-4.048-0 robert$ sudo make install

Well finally. Now why did I want this? I can't remember.
