Segmentation fault compiling on ARM

[abelboldu]

I tried to compile on a RPi 2, because of that issue:

#1148

but also fails to compile:

Would you be able to include the entire compilation sequence to include the setting up of the flags at the beginning?

Looks the same as #1131

May also be related to #355 - there's no C standard for converting between int (as used in the functions in blockexports.c) and C++ bool used to define m_testnet which is how values are passed in.

Is there a way we can either drop bool entirely, or define it somewhere so it's internally consistent, as per http://stackoverflow.com/questions/1921539/using-boolean-values-in-c

Can I also ask why blockexports needs to be in C rather than C++?

#1269

I've brushed the dust off my RPi 2 and successfully built from scratch. I think your issues are with your installation of boost.

Please delete all previous boost installs with apt-get remove --purge libboost* and then sudo rm -rf /usr/local/lib/libboost* and sudo rm -rf /usr/local/include/boost

Then install boost from scratch by pulling down with wget. Building and installing will take at least 12 hours, then building monero itself will take another 4. You will hit an out-of-memory issue linking the daemon so increase the swap size as per: https://www.bitpi.co/2015/02/11/how-to-change-raspberry-pis-swapfile-size-on-rasbian/

See #974. Try Invoking cmake with: -DCMAKE_LINKER=/usr/bin/ld.gold

[moneromooo-monero]

Is gold something that'd be installed with fairly high probability ? If so, it might be a good thing if someone wanted to autodetect it in cmake.

[radfish]

@moneromooo-monero On Arch and on Ubuntu ld.gold is owned by binutils package, so high probability. But, iiurc, the build failure with ld has been fixed already after I reported it at the time: http://lists.gnu.org/archive/html/bug-binutils/2016-08/msg00165.html

[moneromooo-monero]

Nice, thanks.
I'll just call it fixed then.
