I am trying to build and install python 3.6.2 from source on my Raspberry Pi running Raspbian Jessie. Here's how the build process has gone:
$ ./configure --enable-optimizations --enable-ipv6 # everything seems fine
$ make -s -j$(nproc) # everything seems fine except for a few tests being skipped
$ make test # again, a few tests are skipped
$ sudo checkinstall -D make altinstall # FAILURE
The error is:
*snip*
running install_lib
copying build/lib.linux-armv7l-3.6/_codecs_cn.cpython-36m-arm-linux-gnueabihf.so -> /usr/local/lib/python3.6/lib-dynload
error: [Errno 2] No such file or directory
Makefile:1451: recipe for target 'sharedinstall' failed
make: *** [sharedinstall] Error 1
**** Installation failed. Aborting package creation.
Cleaning up...OK
Bye.
But, the file does exist, and so does the destination:
$ ls build/lib.linux-armv7l-3.6/_codecs_cn.cpython-36m-arm-linux-gnueabihf.so
build/lib.linux-armv7l-3.6/_codecs_cn.cpython-36m-arm-linux-gnueabihf.so
$ ls /usr/local/lib/python3.6
config-3.6m-arm-linux-gnueabihf lib-dynload
Basically, wtf. I have tried poking around in the Makefile and setup.py but don't really have the time to fully grok the entire build process. What could be going on here? Should I just give up on using checkinstall? Any advice is welcome.
It turns out that this was a checkinstall bug, of some description. I bit the bullet and just ran sudo make altinstall and everything went off without a hitch. I've looked into checkinstall a bit more and it seems to have a few...difficult bugs. I wouldn't go so far as to label it "buggy," and it works well most of the time, but sometimes it goes wrong and there doesn't seem to be much that can be done about that.
