PyQt 安装 10.7 "Undefined symbols for architecture x86_64"

Question

尝试在OS X 10.7上安装PyQt:

g++ -headerpad_max_install_names -arch x86_64 -Xarch_x86_64 -mmacosx-version-min=10.5 -o w_qpyopengl.app/Contents/MacOS/w_qpyopengl    -F/usr/local/Cellar/qt/4.8.6/lib -L/usr/local/Cellar/qt/4.8.6/lib -framework QtGui -L/opt/X11/lib -L/usr/local/Cellar/qt/4.8.6/lib -F/usr/local/Cellar/qt/4.8.6/lib -framework QtCore 
Undefined symbols for architecture x86_64:
  "_main", referenced from:
      start in crt1.10.5.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[2]: *** [w_qpyopengl.app/Contents/MacOS/w_qpyopengl] Error 1
make[1]: *** [all] Error 2
make: *** [all] Error 2

Make file with

python configure.py -d /Library/Python/2.7/site-packages/ -g -q /usr/local/bin/qmake --use-arch=x86_64

美元路径

LIBRARY_PATH美元

$ echo $LIBRARY_PATH
/usr/lib:

我已经尝试了系统链接/usr/lib到/opt/X11/lib(不存在)。

不知道该怎么办

尝试使用configure-ng.py代替configure.py。这显然是目前推荐的方法。

如果您得到错误fatal error: sipAPIQtCore.h: No such file or directory，请尝试添加

INCPATH+=/path/to/PyQt-mac-gpl-4.11/_qt

转到configure-mg.py命令。例如,

python configure-ng.py -g --sip-incdir=$HOME/Downloads/sip-4.16.1/siplib INCPATH+=$HOME/Downloads/PyQt-mac-gpl-4.11/_qt

如果这构建了一个经常崩溃的PyQt版本(很可能会，因为它对我来说就是这样)，请尝试不使用-g进行配置。
