mysqldb构建错误

Question

我记得我在我的带有Leopard 10.5.7的32位Mac上安装了Python + Django + MySQL + MySQLdb。我在Mac Snow Leopard上尝试了同样的过程。但不幸的是遇到了很多错误...我不知道，但是发生了一些奇怪的事情。请查看错误日志：

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)

这对我来说很管用。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，我使用的是一个定制的编译器(出于过时的原因，太难看了，无法深入研究)

Answer 2

最可能的解释是，您正在尝试将64位版本的MySQL库与仅32位版本的python.org链接(目前，OS X上的所有python.org仅为32位版本)。(您可以在/usr/local/mysql/中对库文件使用file命令来验证这一点)。

一些解决方案：

• 在雪豹上使用苹果提供的python2.6，它是64位的
• 安装32位版本的MySQL MacPorts是一个完整的解决方案，使用MacPorts：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，包括新的python和MySQL客户端库，它们应该都可以正确地一起工作(并且能够通过<代码>D13进行更新)：

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，也就是说，除非您真的喜欢并且有时间进行包管理和安装。从长远来看，这可能会为您省去很多麻烦。

P.S. MacPorts还包括django和PIL的端口：

sudo port install py26-django py26-pil

编辑：

要使用MacPorts，请按照我给here的说明删除python.org安装程序python的影响。不要试图在/usr/bin或/System/Library中删除或修改苹果安装的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。为了避免干扰苹果或第三方的安装，MacPorts将其所有文件安装到一个以/opt/local为根的完全独立的目录结构中。因此，您需要修改.bash_profile以将/opt/local/bin添加到$PATH中。如果您希望首先找到MacPorts版本，请添加类似以下内容：

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

当您开始一个新的终端会话时，您应该可以在python2.6上找到MacPorts python2.6。如果您还想让命令python指向该位置：

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

Answer 3

下面这篇博文帮助我在Mac上编译了MySQLdb 1.2.2：http://www.mangoorange.com/2008/08/01/installing-python-mysqldb-122-on-mac-os-x/

然而，后来我尝试了MySQLDB 1.2.3c1，没有遇到任何开箱即用的编译问题。1.2.2是几年前的版本，并在Python 2.6上引起弃用警告。我只需要切换到1.2.3.c1，看看它是否对您有效。

1.2.3c1是PyPi上的最新版本。
