Facing same issue on Centos 7, looking into it, there appears to be a failure related to autogen.sh in the temporary dir that pip sets up.

You probably will face same error output of:

Hmm, any idea why?

Not sure, but I was able to run the build script from https://github.com/spesmilo/electrum just now and successfully built libsecp256k1.so.0

The script that was able to produce a working build is in contrib/make_libsecp256k1.sh in the https://github.com/spesmilo/electrum repo. The files built, but I'm having to move them by hand. No idea if this will fix the issue, but I'm going to try and install coincurve against those.

When I attempt to build coincurve with python3 setup.py build which calls: autogen.sh

Output here:

I've set the ENV variables as follows:

Now executing python3 setup.py build in the coincurve dir, that failed.

I manually copied the built libsecp256k1 dir from electrum to the copy of the pip created coincurve dir, and the dir from the latest branch of this repo, commented out the portion of setup.py where the installer downloads the source and builds libsecp256k1 ... So far the installer stated that the contents of libsecp256k1 were already created and would need to be made distclean ... I ran that and still get the same error as before, but this time perhaps a bit better info?

So something is triggering the working gcc compiler to fail, but this works fine with electrums contrib libsecp256k1.

I'm surprised there isn't something checking to see if the libsecp256k1 libraries are installed already, instead of just building it.

Hmm, any idea why?

Interesting ... If you could do the same on your Centos 6 system - and preserve the files that get generated by python3.6 -m pip install coincurve you might be able to get some additional details from the autogen.sh output that gets run.

I saved my cached copy, there may be a flag for that...

pip --verbose install coincurve also might provide more info to what is failing.

from verbose output - the location pip attempts the install will be after the --prefix flag:

--prefix /var/volatile/tmp/pip-build-env-skxkqr4l/overlay on my most recent failure. 😆

Here are the flags from the "working" libsecp256k1 compile:

./configure --prefix=/micNfs/tools/tmp/electrum/contrib/secp256k1/dist --enable-module-recovery --enable-experimental --enable-module-ecdh --disable-benchmark --disable-tests --disable-exhaustive-tests --disable-static --enable-shared

the flags in coincurve from pip are: cmd = [ absolute('libsecp256k1/configure'), '--disable-shared', '--enable-static', '--disable-dependency-tracking', '--with-pic', '--enable-module-recovery', '--prefix', os.path.abspath(self.build_clib), '--enable-experimental', '--enable-module-ecdh', '--enable-benchmark=no', '--enable-tests=no', '--enable-openssl-tests=no', '--enable-exhaustive-tests=no',

After hacking on it for some time, I have no idea if it's going to be stable, but I was able to build a weird version for my cpu on Centos 7:

Libraries have been installed in: /usr/local/lib

If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the `-LLIBDIR' flag during linking and do at least one of the following:

• add LIBDIR to the `LD_LIBRARY_PATH' environment variable during execution
• add LIBDIR to the `LD_RUN_PATH' environment variable during linking
• use the `-Wl,-rpath -Wl,LIBDIR' linker flag
• have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages.
