undefined reference to '__gmpn_sub

Bushstar commented at 2:26 pm on November 20, 2014: none

I’m a tad stuck now using secp256k1 on Windows which makes life harder. I have compiled GMP-6.0.0a and used the static lib to compile secp256k1. Everything goes without fault. However when I use the secp256k1 in a coin I get the errors below when compiling. Any help with this would be appreciated, I have tried linking lgmp straight into the client to see if this resolves the issue without joy.

@theuni ?

The error above I get when trying to compile the Qt client using Mingw gcc 4.8.2. I read something from Feb this year stating that there were some issues with libgmp and some versions of gcc. I will update to see if this helps and report back.

EDIT: I found this, were you referencing it? https://github.com/theuni/secp256k1

Bushstar commented at 7:08 pm on November 20, 2014: none

No luck, moved to gcc 4.9.1 with the same result. Statically compiled all libs from scratch but still get the same errors. I also tried the @theuni repo of this software and got the same result.

@Bushstar Could you please try with bitcoin? The error looks link-order related. I have no idea what other coins are doing. If they’re not integrating the libsecp source directly, they’ll need to use pkg-config as usual to get dependencies sorted out.

I’m inclined to believe this is not our bug.

theuni commented at 7:16 pm on November 20, 2014: contributor

@Bushstar I’d at least need to see the link-line to verify where the bug lies.

theuni commented at 7:29 pm on November 20, 2014: contributor

That’s not the link-line. Please use “make V=1”

Bushstar commented at 9:40 pm on November 20, 2014: none

Many thanks for stopping by. The full output from building secp256k1 with V=1 is linked in below. http://pastebin.com/mNpK0Etc

Also the complete Qt pro file. http://pastebin.com/GKXKaJhw

theuni commented at 4:15 am on November 21, 2014: contributor

You’re not linking against libgmp. Please instruct your upstream to use proper dependency detection (pkg-config).

I’ll be helpful in this case and give you the hard-coded simple (wrong) fix: change:

0-l secp256k1

to:

0-lsecp256k1 -lgmp

This is not our bug.

Bushstar commented at 12:36 pm on November 21, 2014: none

Thanks for taking a look into this, I did try linking -lgmp but linked it before secp256k1, fool on me. The client is now compiling. If you email me your Bitcoin address I will happily send you 0.1BTC as a small thank you. bushsolo (at) gmail.com

Diapolo commented at 2:20 pm on November 26, 2014: none

@theuni I can confirm that -lgmp needs to be after -lsecp256k1 in order to get it working in Windows :). Thanks for that great hint!

theuni commented at 6:58 pm on December 8, 2014: contributor

@Bushstar Thanks, but that’s not necessary. @Diapolo No problem. In general for the bfd/gold linkers, the link order should go from most dependent to least dependent.
