Hey everyone, I was trying to compile pypy and made the following mistakes: - On this page: http://pypy.org/download.html I couldn't figure out whether I was supposed to run all three of these commands: pypy ../../rpython/bin/rpython -Ojit targetpypystandalone # get the JIT version pypy ../../rpython/bin/rpython -O2 targetpypystandalone # get the no-jit version pypy ../../rpython/bin/rpython -O2 --sandbox targetpypystandalone # get the sandbox version or just one. - Once I got it installled I didn't realize there was an additional step after pypy-c was created. - I tried running python package.py -h and that didn't do what I expected (show help dialog) - I tried running package.py with the right options and it hung with this message (on both Mac and Centos): sll_os.ll_os_getenv(sPYPY_GENERATIONGC_NURSERY The only Google search results for this are an IRC channel from 2 years ago. It turned out I didn't want the Sandbox option, I think. - I tried compiling outside the sandbox and got this error: raise NoTTY("Cannot start the debugger when stdout is captured.") It turns out this is a red herring and the real error was way above that: error: ffi.h: No such file or directory It would be nice if these were more obvious.. of course I expect to run into issues but the errors could be more clear when they are. Continuing the install process now, will post updates here as I have them. I am happy to help try and fix these where I can, if you can point me in the right direction - I have a fair amount of experience working with new users at Twilio. I have also made exactly one commit to Pypy source code: https://bitbucket.org/pypy/pypy/commits/665baf750859/ Pypy is a lovely project and I'd love to try and help make this process easier.
