On my Jolla 1, I have syncevolution for CardDAV sync with a radicale server. Native CalDAV works, but for CardDAV I still need syncevolution.
On my Jolla C, I can't install syncevolution from OpenRepos: it depends on libical.so.0, but my Jolla C has libical.so.1. So I got the source from [here](https://people.debian.org/~ovek/sailfish/). I end up stumbling on this error:

make[2]: *** [src/syncevo/src_syncevo_libsyncevolution_la-LocalTransportAgent.lo] Error 1
The precise error changes every invocation, but always it is the assembler complaining about invalid code produced by compiling this particular file src/syncevo/LocalTransportAgent.cpp.
I'm at a loss how to proceed. I don't know C++ and I'm unfamiliar with the build environment. I don't know whether this is truly a compiler bug or not. I thought I'd bring it up here first, and hopefully somebody more familiar with this stuff can give it a try.
By the way, I never have stability issues with the machine on which I'm compiling, and it isn't overclocked. I'm aware that this class of errors can happen with failing hardware, but I have no reason to believe it is related to that.
I'll now describe how I got to where I am now.
At first, I upgraded an ancient Sailfish SDK I already had installed, thinking "let's try that first". I'm not sure how the author of the Sailfish UI for syncevolution built the package, but floundering around a bit, I ended up creating the directory "rpm" in the unpacked source, copying the spec file that is in the root of the unpacked source there, and adding intltool to the BuildRequires, since the build complained about not having that installed.
Issuing a `mb2 -t SailfishOS-armv7hl build` in the unpacked source dir ended up erroring out as described. At this point, I removed the old Sailfish SDK and installed a fresh one. However, the Virtual Machine of the old SDK somehow survived, creating some Frankenstein VM where it ended up using stuff I had already removed, very odd.
So I once more removed the SDK, checking my process list to make sure VirtualBox was no longer running, and did a fresh SDK install. You can read how it went from there in [this gist](https://gist.github.com/DigitalBrains1/60887ce1759f4df3490158c14e9ff6d9). The spec file I copied at the start of that gist is [here](https://gist.github.com/DigitalBrains1/0345fa8352d49cd64e3e967062545c4d); its only change from the spec file from the source is the added intltool BuildRequires.
Can anybody provide more insight? Is this a compiler bug? And also: could somebody please compile a new syncevolution for SailfishOS v2.0.2.43? :-)
