<a href="https://gitlab.com/aberaud">Adrien Béraud</a> created an issue <a href="https://gitlab.com/gnutls/gnutls/-/issues/1045">#1045</a>:

<p dir="auto">When building a static library of gnutls, <code>nettle_ecc_scalar_random</code> is included in the resulting static library:</p>
<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code><span id="LC1" class="line" lang="plaintext">nm -C x86_64-linux-android/lib/libgnutls.a | grep nettle_ecc_scalar_random</span>
<span id="LC2" class="line" lang="plaintext">00000000000001f0 T nettle_ecc_scalar_random</span></code></pre>
<p dir="auto">However this symbol is really part of <code>libhogweed</code> (Nettle):</p>
<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code><span id="LC1" class="line" lang="plaintext">nm -C x86_64-linux-android/lib/libhogweed.a | grep nettle_ecc_scalar_random</span>
<span id="LC2" class="line" lang="plaintext">00000000000001f0 T nettle_ecc_scalar_random</span></code></pre>
<p dir="auto">So when building an executable with <code>-lgnutls -lhogweed -lnettle</code>:</p>
<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code><span id="LC1" class="line" lang="plaintext">ld: error: x86_64-linux-android/lib/libhogweed.a(ecc-random.o): multiple definition of 'nettle_ecc_scalar_random'</span>
<span id="LC2" class="line" lang="plaintext">ld: x86_64-linux-android/lib/libgnutls.a(ecc-random.o): previous definition here</span>
<span id="LC3" class="line" lang="plaintext">clang90++: error: linker command failed with exit code 1 (use -v to see invocation)</span></code></pre>
<p dir="auto">Or if trying to build without libhogweed (just <code>-lgnutls -lnettle</code>), the linker fails at runtime:</p>
<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code><span id="LC1" class="line" lang="plaintext">dlopen failed: cannot locate symbol "nettle_rsa_pss_sha256_sign_digest_tr" referenced by "/data/app/blah.so"...</span></code></pre>
<p dir="auto">Expected behavior:</p>
<p dir="auto">No definition from libhogweed or nettle should be included in the static library</p>
