undefined reference to `secp256k1_ecdsa_sign_recoverable' #7261

going through the make process, i run into this error: (i tried running a git clean)

This is a problem resulting from linking against an older build result of libsecp256k1.

Try make clean. If that doesn't work, try make clean inside src/secp256k1 directory. If that doesn't work, use git clean -dfx (which deletes all non-committed files; be careful if you have other work in the working directory).

Our build system is broken, so you will need to re-run autogen.sh and/or configure manually. :(

@sipa yeah that just took me back to the beginning, make clean didnt work, make clean in secp256k1 didnt work, and git clean -dfx just brought me back in a circle lol

after trying to do it manually in secp256k1 dir:

testb0x@testb0x-VirtualBox:~/bitcoin/src/secp256k1$ make ./gen_context /bin/bash: ./gen_context: cannot execute binary file: Exec format error Makefile:1507: recipe for target 'src/ecmult_static_context.h' failed make: *** [src/ecmult_static_context.h] Error 126

@doged What is git log --oneline -1?

@MarcoFalke be9a9a3 Merge pull request #7214

i'm really really not sure how that helps.

@MarcoFalke ?

I just wanted to make sure you are not running an odd commit. And your OS is latest Ubuntu?

@MarcoFalke correct, ubuntu 15

been getting alot of permission errors along the way, that might have something to do with it. for some reason i had to chmod+x build_detect_platform in leveldb, etc

I don't think chmod +x will solve any issues here. It may even create some. Not sure why people keep doing those...

I can try to revive my Ubuntu box tomorrow and have a look. If you are bored in the meantime. You could try:

git reset --hard be9a9a3
git clean -dfx
./autogen.sh
./configure
make

and dump the output to some pastebin.

@luke-jr i keep getting stuck here, which is odd because i can gcc gen_context in the dir, but even still it breaks on build

why isnt it showing gcc before the -I. ? is there an easy command line fix for this?

@doged I can't reproduce on a fresh Ubuntu 15.10:

$ sudo apt-get install git vim build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils
$ sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev
$ sudo apt-get install libdb-dev libdb++-dev 
$ sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler
$ git clone https://github.com/bitcoin/bitcoin.git
$ cd bitcoin/
$ git log -1 --oneline 
be9a9a3 Merge pull request [#7214](/bitcoin-bitcoin/7214/)
$ ./autogen.sh ;./configure --with-incompatible-bdb; make

@doged sounds like it's not finding your native gcc. Try exporting CC_FOR_BUILD=gcc

@theuni that fixed it. submitting pull request and closing. i hope this helps anyone else who runs into this issue on a fresh install.
