[sage-devel] Workaround for missing link to MacTex for MacOS Sage app

2017-01-19 Thread Michael Frey
I found that when trying to access LATeX (MacTeX) calls in a Sage notebook via MatPlotLib or directly Sage would report that it could not find some TeX function. It appears that the PATH variable being used by the Sage app is pointing to /usr/texbin, not /Library/TeX/texbin. As a workaround I

For the cmp problem, Jeroen as suggested implementing our own cmp function. Thus, we just add this to the imports of every file that we don't want to go to rich comparisons (i.e., that needs it), which tries calling __cmp__ then falls back to ordering. This should at least get all of Sage to co

Hi, A bit more clarification. I upgraded to 7.5.1 using sage --upgrade. There is a copy of libiconv in /usr/local/lib and one that the Mac OS installs in /usr/lib. The command "sage -installed" reports that iconv is installed. This is obviously a minor problem, given that no one else has rep

Right now (pre-ticket) if you try to build sage on OSX Sierra and above, it will be built without OpenSSL support. I'm not sure what happens if you download a prebuilt package but somehow I assumed that if you don't have OpenSSL installed, then you can't use OpenSSL (otherwise I don't understand th

There is no summary page for the cmp situation anywhere. You can look at #16537 and #17175 To know how this was solved in some cases, look at the tickets here: https://trac.sagemath.org/query?component=python3 having cmp in the title. Almost every case is different, because it can be either py
