I followed the directions here:
http://dot-bit.org/BuildNamecoinQTFromSourceOn this step:
qmake "USE_UPNP=-"
I get these errors:
Project MESSAGE: Building without UPNP support
Project MESSAGE: Building without IPv6 support
sh: 1: /usr/lib/x86_64-linux-gnu/qt5/bin/lrelease: not found
WARNING: Failure to find: auxpow.cpp
WARNING: Failure to find: headers.h
RCC: Error in '../src/qt/bitcoin.qrc': Cannot find file 'locale/bitcoin_bg.qm'
[...]
I also tried using QT Creator and the namecoin-qt.pro file but that gave me an error about auxpow.cpp. I'd like to use Namecoin for something but if I can't get it to work then my users certainly won't be able to.
Which source are you using? What OS? Any other info that you think might be helpful.
Edit: I just tried it out here and didn't see anything like that ... seems to be saying some source/header files not found?
Looks like some path is missing / incorrect.
