mysqldb构建错误

Question

我记得在我的 32 位 Mac 上使用 Leopard 10.5.7 安装 Python + Django + MySQL + MySQLdb。 我用 Mac Snow Leopard 尝试了同样的程序。但不幸的是遇到了很多错误...... 我不知道，但奇怪的事情正在发生。请看错误日志：

这是我个人的 makefile 规则

MYSQLDB_VERSION=1.2.3c1
MYSQLDB_TARGET=$(BUILD_FLAGS_DIR)/mysqldb
MYSQLDB_PACKAGE=MySQL-python-$(MYSQLDB_VERSION).tar.gz
MYSQLDB_PACKAGE_URL=http://downloads.sourceforge.net/project/mysql-python/mysql-python-test/$(MYSQLDB_VERSION)/$(MYSQLDB_PACKAGE)

.PHONY: mysqldb mysqldb-download
mysqldb: $(MYSQLDB_TARGET)
mysqldb-download: $(DOWNLOAD_DIR)/$(MYSQLDB_PACKAGE)

$(MYSQLDB_TARGET): $(INIT_TARGET) $(MYSQLDB_DEPS) $(DOWNLOAD_DIR)/$(MYSQLDB_PACKAGE)
    -rm -rf $(UNPACK_DIR)/MySQL-python-$(MYSQLDB_VERSION)
    tar -m -C $(UNPACK_DIR) -xzvf $(DOWNLOAD_DIR)/$(MYSQLDB_PACKAGE)
    -cd $(UNPACK_DIR)/MySQL-python-$(MYSQLDB_VERSION); \
    for patch in $(PATCH_DIR)/mysqldb-$(MYSQLDB_VERSION)_$(ARCH)_*; \
        do patch -p1 < $$patch; \
    done
    cd $(UNPACK_DIR)/MySQL-python-$(MYSQLDB_VERSION); export CC="gcc -m64" FC="g95 -m64" CPPFLAGS="-I$(RUNTIME_DIR)/include" CFLAGS="-m64 -I$(RUNTIME_DIR)/include" LD_LIBRARY_PATH=$(RUNTIME_DIR)/lib64:$(RUNTIME_DIR)/lib:$$LD_LIBRARY_PATH PATH=$(RUNTIME_DIR)/bin:$$PATH PYTHONPATH=$(RUNTIME_DIR)/lib/python2.5/site-packages/; $(RUNTIME_DIR)/bin/python2.5 setup.py install --prefix=$(RUNTIME_DIR)
    touch $(MYSQLDB_TARGET)

$(DOWNLOAD_DIR)/$(MYSQLDB_PACKAGE):
    for package in $(MYSQLDB_PACKAGE_URL); \
    do \
        echo -n "Downloading $$package... ";  \
        cd $(DOWNLOAD_DIR); curl -L -O $$package; \
        echo "done"; \
    done
    touch $@

ALL_RUNTIME_TARGETS+=$(MYSQLDB_TARGET)
ALL_DOWNLOAD_TARGETS+=$(DOWNLOAD_DIR)/$(MYSQLDB_PACKAGE)

还有一个补丁

$ more mysqldb-1.2.3c1_x86_64-apple-darwin10_patch-000 
diff -Naur MySQL-python-1.2.3c1/setup.py MySQL-python-1.2.3c1.new/setup.py

     from setup_windows import get_config

 metadata['ext_modules'] = [Extension(sources=['_mysql.c'], **options)]
 metadata['long_description'] = metadata['long_description'].replace(r'\n', '')
 setup(**metadata)

它对我有用。我不能保证，但是……也许你会在里面找到一些有趣的提示。

请注意，我使用的是自定义编译器（由于过时的原因太难看，无法深入研究）

Answer 2

最可能的解释是您试图将 64 位版本的 MySQL 库与仅 32 位版本的 Python 链接（目前，OS X 的所有 python.org 安装程序都是 32 位的只要）。 （您可以通过对/usr/local/mysql/ 中的库文件使用file 命令来验证这一点。

一些解决方案：

• 使用 Apple 提供的 python2.6 64位的雪豹

• 安装 32 位版本的 MySQL 库

• 使用MacPorts安装完整的解决方案：install the base MacPorts infrastructure，然后安装MySQLdb adapter for python 2.6（或2.5），它还将安装所有必要的依赖项，包括一个新的 python 和 MySQL 客户端库应该都可以正常工作（并且是 可以被MacPorts更新）：

  sudo port install py26-mysql # or py25-mysql

对于在OS X 上使用MySQL 和python，我推荐最后一个解决方案，即除非你真的喜欢并且有时间进行包管理和安装。从长远来看，它可能会为您省去很多麻烦。

附： MacPorts 还包括django 和PIL 的端口：

sudo port install py26-django py26-pil

编辑：

要走MacPorts 路线，请按照我给here 的说明删除python.org 安装程序python 的影响。不要试图删除或修改/usr/bin 或/System/Library 中Apple 安装的Python 文件；它们是OS X 的一部分。然后按照上面引用的说明安装MacPorts。为了避免干扰 Apple 或第三方安装，MacPorts 将其所有文件安装到以/opt/local 为根的完全独立的目录结构中。因此，您需要修改您的.bash_profile 以将/opt/local/bin 添加到您的$PATH。如果您希望首先找到 MacPorts 版本，请添加如下内容：

export PATH="/opt/local/bin:${PATH}"

当你开始一个新的终端会话时，你应该在python2.6 找到MacPorts python2.6。如果你还想让命令python 指向那里：

$ sudo port install python_select
$ sudo python_select -l
Available versions:
current none python26 python26-apple
$ sudo python_select python26

Answer 3

以下博客文章帮助我在 Mac 上编译 MySQLdb 1.2.2： http://www.mangoorange.com/2008/08/01/installing-python-mysqldb-122-on-mac-os-x/

但是，后来我尝试了 MySQLDB 1.2.3c1，并且开箱即用地编译没有任何问题。 1.2.2 已经有好几年了，在 Python 2.6 上会出现弃用警告。我只是切换到 1.2.3.c1 看看是否适合你。

1.2.3c1 是 PyPi 上的最新版本。

您似乎需要重新安装/更新 XCode（构建工具）
