Hello,

I'm pretty new to FreeBSD and I'm trying to port/build Tokumx (a MongoDB fork) on FreeBSD10. I've already fixed some issues during the build process and I'm stuck with the following error:

Code: 
[ 47%] Building CXX object src/mongo/platform/CMakeFiles/platform.dir/backtrace.cpp.o

I'm not a C/C++ expert and I can't figure how to solve this issue. Perhaps someone here who has been working with MongoDB before might be able to assist?

Btw: I'm using GCC47, also tried GCC48 w/o without any luck.

My build instructions:
Code: 
CC=gcc47 CPP=cpp47 CXX=g++47 cmake --disable-warnings-as-errors -D CMAKE_BUILD_TYPE=Release -D TOKU_DEBUG_PARANOID=OFF -D USE_VALGRIND=OFF -D USE_BDB=OFF -D BUILD_TESTING=OFF -D TOKUMX_DISTNAME=1.5.0 ..
gmake
 
That's a good advice, I'm currently reading the diff files if there's anything that might be related to my issue. Unfortunately the patch files don't apply to the tokumx source, at least the ones I tried for SConstruct were too different.

Edit:
Ok, I have manually patched the SConstruct files but the error is still the same. The other patches don't seem to address this issue.
 
After reading a lot of freebsd FreeBSD and cmake manual pages, I eventually compiled tokumx. Unfortunately the binary won't start because it can't detect the CPU frequency correctly:

Here's the output from: truss mongod

I installed linprocfs and mounted it in /compat/linux/proc. I've also tried brandelf -t Linux /usr/local/bin/mongod but it still fails to read /proc/cpuinfo. Does anyone have an idea how to trick the mongod process into reading the correct location?
 
Thanks for your suggestion. hw.cpufrequency indeed looks like OSX, but that's not the point. I don't want to change the source of TokuMX, I want the binary to read from /compat/linux/proc/cpuinfo which seems to be the obvious choice to me.
Furthermore sysctl -a | grep dev.cpu.0.freq doesn't return anything on my machine. Even if I just sysctl -a | grep freq there's nothing related to the cpu frequency.
 
Ok you guys are right - I changed the source and according to the stacktrace I got past the cpu-frequency issue. The binary still fails with a segfault and I'm running out of ideas and motivation to fix this. Here's a stacktrace on Pastebin: http://pastebin.com/rjtc4xVw
