The following procedure fails. Am I missing something?

  • Install various Ubuntu packages (prerequisites for compilation)
  • Get http://downloads.sourceforge.net/wxpython/wxPython-src-3.0.1.1.tar.bz2
  • Uncompress to wxPython-src-3.0.1.1/
  • Create new virtualenv called test
  • Activate test virtualenv
  • In terminal, from wxPython-src-3.0.1.1/:

    ./configure --prefix=/home/username/.virtualenvs/test --with-gtk2 --enable-unicode --with-opengl
    #lots of output, confirms "Configured wxWidgets 3.0.1 for `x86_64-unknown-linux-gnu'"
    
    make install
    #lots of output, confirms:
    # The installation of wxWidgets is finished.  On certain
    # platforms (e.g. Linux) you'll now have to run ldconfig
    # if you installed a shared library and also modify the
    # LD_LIBRARY_PATH (or equivalent) environment variable.
    
    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/.virtualenvs/test/lib
    # don't run ldconfig since that is a system tool, not appropriate for virtualenv?
    
    cd wxPython
    python setup.py install
    # lots of output, starting:
    # WARNING: WXWIN not set in environment. Assuming '..'
    # Found wx-config: /home/username/.virtualenvs/test/bin/wx-config
    #     Using flags:  --toolkit=gtk2 --unicode=yes --version=3.0
    # Preparing CORE...
    # Preparing STC...
    # Preparing GLCANVAS...
    # Preparing GIZMOS...
    # running install
    # etc
    

The final command fails with:

src/gtk/_core_wrap.cpp:20407:7: note: ‘arg3’ was declared here
   int arg3 ;
       ^
src/gtk/_core_wrap.cpp: In function ‘PyObject* _wrap_Image_SetAlphaBuffer(PyObject*, PyObject*, PyObject*)’:

我曾经python setup.py install &> ~/error.txt将错误消息传递给知识渊博的同事,他们发现 C 编译正在使用该-Werror=format-security标志。这个版本的 wxPython(可能还有其他版本)无法使用该标志进行编译。

我的$CPPFLAGS$CFLAGS环境变量是空的。事实证明,这个标志是由hardening-wrapper触发的。

所以,我通过调用最后一步来覆盖标志,如下所示,wxPython 安装成功:

CFLAGS=-Wno-error=format-security CPPFLAGS=-Wno-error=format-security python setup.py install
