<div class="md" style="color: #333238; word-wrap: break-word;">
<p dir="auto" style="color: #333238; margin: 0 0 16px;" align="initial">When statically linking with libgnutls.a and libhogweed.a, the linker complains about multiple definition of several <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; margin-top: 0; font-weight: inherit; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; vertical-align: bottom; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>mpn_</code> functions.
In my case it is building and linking the fuzzers for <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; font-weight: inherit; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; vertical-align: bottom; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>wget</code> and <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; font-weight: inherit; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; vertical-align: bottom; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>wget2</code> on oss-fuzz.
