src/key.cpp:134: {anonymous}::CECKey::CECKey(): Assertion `pkey != __null' failed

[rgasch]

I have built the qt-version of vertcoin on Fedora20 by doing the following (this is the first time I've ever compiled a QT program, so it may be that I'm doing something wrong):

qmake-qt5 make clean make ./vertcoin-qt

and I get the following:

./vertcoin-qt libpng warning: iCCP: known incorrect sRGB profile vertcoin-qt: src/key.cpp:134: {anonymous}::CECKey::CECKey(): Assertion `pkey != __null' failed.

Please advise. If I can help diagnose the problem any further, please let me know what to do.

Hi,

The latest makefile should work with qmake-qt5, but can you also try qmake-qt4 (or just plain qmake) and see what happens? Someone else reported something similar recently, and it was fixed by building with the qt4 qmake.

I tried qmake-qt4 before that and got exactly the same issue. I then switched to qmake-qt5 since I figured "newer must be better" :-) ... so in terms of this issue, there is no difference between qt4 and qt5.

Ok, looks like it's because the Fedora openssl builds don't implement one of the elliptic curve functions needed (secp256k1) - it's a licensing thing. Here's a patch for you:

In the main vertcoin folder (so, at a level where if you do ls you can see subdirectories contrib, src, doc, share etc)

wget http://pastebin.com/raw.php?i=iFYJsgus -O patch

patch -p1 <patch

rm patch

qmake

make

Incidentally, I did build against qt4 (installed qt4-dev-tools on ubuntu, not sure what that would be on fedora), so if it still doesn't build after patching (and it's not just a straight dependency issue) try building against qt4 too.

Let me know if you have any more issues.

Paul

Works like a charm! Thanks for the awesome support.

Thanks! It works also for the feathercoin client on Fedora 20.
