Can't build on Mac OS X (10.10.5)

[scttnlsn]

Trying to get Tahoe setup on Mac OS X but the build fails when trying to install "pycryptopp". Here's the full output: ​https://gist.github.com/scttnlsn/4a1663b7a4917c9751a6 Any advice?

Hi there. I'm sorry you've hit this bug, and thank you for reporting it.

The critical part of the log that you posted is this:

Running pycryptopp-0.6.0.1206569328141510525648634803928199668821045408958/setup.py -q bdist_egg --dist-dir /var/folders/z3/x8fdxj9x1rv8zt4ylnkjcgyh0000gn/T/easy_install-oDsLyH/pycryptopp-0.6.0.1206569328141510525648634803928199668821045408958/egg-dist-tmp-OVEURv
src-cryptopp/integer.cpp:534:2: error: unknown token in expression
        ".intel_syntax;"
        ^

Apparently the toolchain on your system is incompatible with the assembler syntax in pycryptopp.

Could you please let us know version of OSX, and also show us the output of:

python misc/build_helpers/show-tool-versions.py 

This patch would fix your problem:

​https://github.com/tahoe-lafs/pycryptopp/pull/23

as described in this ticket:

​https://tahoe-lafs.org/trac/pycryptopp/ticket/85

Let me know if you want to help us test that patch.

[zooko]

oh, I see that you said the version of OSX you are using in the subject line -- 10.10.5.

I've give that pull request a try and report back.

I'm able to build ​https://github.com/tahoe-lafs/pycryptopp/pull/23 successfully. Is there a way to then build tahoe-lafs using the alternate build of pycryptopp?

[warner]

I brought the pycryptopp buildbot back online: ​https://tahoe-lafs.org/buildbot-pycryptopp/waterfall . And I added an OS-X buildslave that has (for now) 10.10.5 . The builder is red, as we expect.

I think the next step is for Zooko to land the first two patches of ​PR 26, which turns off the .asm code. That should make the OS-X build go green. Then we can land the rest of PR26, or not. Then we need a new release.

Zooko: note that there's a new Versioneer, in case you want to upgrade that too while you're at it. It won't give you the verbose-and-precise 120-bit decimal version string, though :).

Hello, I am having the same problem when using pycryptopp == 0.6.0.1206569328141510525648634803928199668821045408958 as a direct dependency within a ​Pyramid project. I think pycryptopp is needed for ​Beaker to work properly, which is another dependency of my project. I am also developing on OSX Yosemite 10.10.5. Any update on the problem?

[zooko]

We just landed ​https://github.com/tahoe-lafs/pycryptopp/pull/27 in trunk which should fix this issue, @jeanmichel. Sorry for the delay! We'll make a new release of pycryptopp soon.

This still isn't released: ​https://pypi.python.org/pypi/pycryptopp
