python - mysqldb 构建错误

Question

我记得在我的 32 位 Mac 上使用 Leopard 10.5.7 安装了 Python + Django + MySQL + MySQLdb。我在 Mac Snow Leopard 上尝试了相同的过程。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。请查看错误日志:

Answer 1

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)

还有补丁

$ more mysqldb-1.2.3c1_x86_64-apple-darwin10_patch-000

这对我有用。我不能保证，但是……也许你会在里面发现一些有趣的提示。

请注意，我使用的是自定义编译器(由于过时的原因太丑陋而无法深入研究)
