<div><span></span>Dear all,</div><div>The error I encountered when configuring Mono is "<span style="background-color: rgba(0, 0, 0, 0); font-size: 10.5pt; line-height: 1.5;">configure: error: unable to find a way to determine timezone</span><span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">"</span></div>
<div>And I checked the standard libraries, there is a structure called <b>tm</b> in <time.h> header file, it includes some members like tm_sec, tm_min, and so on. </div><div>And RTEMS does not provide this, so anyone can help me with this? Thanks a lot.</div><div><br></div><hr style="width: 210px; height: 1px;" color="#b5c4df" size="1" align="left">

<div> </div>
<div>Nothing seems to be working on FreeBSD 12 right now. There just seems</div>
<div>to be lots of broken stuff. TrueOS moved over to a rolling release a</div>
<div>little while ago and I've never tried to do any development on it</div>
<div>before. Building from 12-CURRENT seems like an enticing idea but...</div>
<div>I've run into a lot of issues (or I feel like I have anyway). I</div>
<div>abandoned Arch for Debian because I didn't want to deal with rolling</div>
<div>releases in embedded development (the little I do). I may have to</div>
<div>consider rolling my own FBSD Desktop instead of using TrueOS.</div>
<div> </div>
<div>Anyway, this is about mono. I got mono to build natively on Debian. I</div>
<div>got the RTEMS sparc simulator from the quick start to build (OMG, what</div>
<div>do I do with that now??? A manual reference for the next steps would</div>
<div>be great cause I can't find it).</div>
<div> </div>
<div>I tried modifying OPs (Original Poster) command line to work with my env:</div>
<div> </div>
<div>#LD_LIBRARY_PATH is from</div>
<div>http://www.mono-project.com/docs/compiling-mono/compiling-from-git/</div>
<div> </div>
<div>env LD_LIBRARY_PATH=/home/russellh/rtems/4.12/bin/ \</div>
<div>./autogen.sh \</div>
<div>--prefix=/opt/Mono/mono-4.8.1.0/mono-arm \</div>
<div>--target=arm-rtems4.12 \</div>
<div>--host=x86_64-unknown-linux \</div>
<div>CC=/home/russellh/rtems/4.12/bin/sparc-rtems4.12-gcc \</div>
<div>CFLAGS="-qrtems"</div>
<div> </div>
<div>This doesn't work. It fails to find the linker and won't configure.</div>
<div>Output is here: https://pastebin.com/Twt36Qph</div>
<div> </div>
<div> </div>
<div>It's frustrating because everything in mono configuration is</div>
<div>autogenerated. That means I can't find the conftest.c file. Anyway,</div>
<div>The issue is the linker location is out to lunch:</div>
<div> </div>
<div>/home/russellh/rtems/4.12/lib/gcc/sparc-rtems4.12/7.1.0/../../../../sparc-rtems4.12/bin/ld:</div>
<div>cannot open linker script file linkcmds:</div>
<div> </div>
<div>As noted above, the compiling-from-git section said to add</div>
<div>LD_LIBRARY_PATH. I tried exporting it first, then tried the env trick.</div>
<div>No luck either way.</div>
<div> </div>
<div>If I cared to pursue this (which I don't) I would await an RTEMS reply</div>
<div>and then likely contact the mono team. However, a note from an</div>
<div>ex-collegue: The are moving a very large number of servers from</div>
<div>Microsoft to Linux (save $$$) and their evaluation of Mono was so</div>
<div>dismal they decided to re-factor to work with DotNet Core instead.</div>
<div>They have a HUGE amount of code to refactor! And those are big beefy</div>
<div>*servers* with lots and lots of memory.</div>
<div> </div>
<div>This exercise has been very instructive for me. Once I figure out how</div>
<div>to get the simulator working I'll look at linking in Lua and then</div>
<div>perhaps DotNetCore. That however requires build clang and llvm 3.9 and</div>
<div>a bunch of stuff I just don't want to deal with when Lua is there for</div>
<div>me.</div>
<div> </div>
<div>Good luck Xuelin Tian, I won't be responding further.</div>
<div> </div>
<div>Cheers,</div>
<div>Russ</div>
