Try This, You want to remove secp256k1 from Linda/src then rebuild it inside.

cd Linda/src

rm -r secp256k1

git clone http://www.github.com/bitcoin/secp256k1

cd secp256k1

git checkout a1d5ae1

./autogen.sh

./configure --enable-module-recovery

make

make install

[DemonRx]

Good news, it finally compiled the -qt, the bad news when trying to run it:

[libsecp256k1] illegal argument: Invalid flags
Aborted (core dumped)

Also the --enable-module-recovery option doesn't exist:

configure: WARNING: unrecognized options: --enable-module-recovery

However there's another secp256k1 repo that contains such option (but this one hasn't worked for me):

https://github.com/bitcoin-core/secp256k1

unless I need to figure out which commit to checkout on it?

Thank you for helping with this. just need a lil more fidgeting to get it working it seems...

[DemonRx]

What also makes even less sense, is that the daemon (Lindag) compiles without issue as-is or any changes to the src, it's only the -qt that's having the problem...

I had the problem D3m0nKingx reported in the beginning of this thread. I tried the solution suggested by RangaBoom, and that problem looks solved, but now I've got this error:

Fibroblasto, in each .cpp file that fails, find:

bool* pfMissingInputs = false;

and replace with:

bool* pfMissingInputs;

Thank you @mccomber .
