Eclipse: spaces instead of tabs

This really bugged me for a while, code formatting was quite miserable outside of the editor. You just have to go into --> preferences --> editor --> Text Editors

Building bitcoin/litecoin on mac os x missing EC.h

For my own fun, I was playing around with bitcoin, to check how the parameters of the cryptocurrencies can be modified. After recent upgrades to my OS, I could not build any longer the bitcoind. Seems like something changed on that side. Now this command ./configure --with-gui=qt5 --enable-debug Was sistematically producing  configure: error: OpenSSL ec header missing EC is the file for elliptic curve cryptography. I had brew correctly configured, and the header files were all correctly present. After some time spent inspecting the issue, on github I was able to find the solution for this problem. I simply add to export the following export LDFLAGS=-L/usr/local/opt/openssl/lib export CPPFLAGS=-I/usr/local/opt/openssl/include There is aksi pull request on bitcoin for that, I hope I could save you some time https://github.com/bitcoin/bitcoin/pull/6885/files?diff=split&unchanged=expanded
