我尝试为 pyRFC 创建一个独立的轮子:http: //sap.github.io/PyRFC/install.html
我有所需的(封闭源代码)库和头文件。
如果我将库和头文件复制到 $VIRTUAL_ENV/lib 和 $VIRTUAL_ENV/include,安装 pyRFC 就可以了。
现在我尝试创建一个包含封闭源库文件的轮子。
但我失败了。
如果我解压缩轮子,它只包含以下内容:
(pypi)pypi@pypiserver:~> unzip -l packages/pyrfc-1.9.91-cp27-cp27mu-linux_x86_64.whl
Archive: packages/pyrfc-1.9.91-cp27-cp27mu-linux_x86_64.whl

缺少 extra_objects(见下文)。
如何修改 pyRFC 的 setup.py 以使轮子包含来自 $VIRTUAL_ENV/lib 的库?
这是setup.py:https://github.com/SAP/PyRFC/blob/master/setup.py
我为 setup.py 尝试了这个补丁

如果我安装并运行库而没有libsapnwrfc.so
收到此错误:
Traceback (most recent call last):

ImportError: libsapnwrfc.so: cannot open shared object file: No such file or directory
如果我跟踪打开的调用,我发现它只查看库的根级别。该库无法在 virtualenv(即 /home/other)中进行搜索:
strace python test-pyrfc.py 2>&1 | grep libsapnwrfc.so
open("/lib64/tls/x86_64/libsapnwrfc.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

write(2, "libsapnwrfc.so: cannot open shar"..., 73libsapnwrfc.so: cannot open shared object file: No such file or directory) = 73
我想通过 wheel 将“libsapnwrfc.so”安装到 virtualenv 中,因为这使我能够拥有多个独立的环境。我可以通过 RPM 或配置管理安装它,但我想避免它。
