I tried to build Fragments with the libtransmission.a static library but compilation fails with this error message: ``` cc -o src/fragments src/fragments.p/meson-generated_.._.._data_de.haeckerfelix.Fragments.c.o src/fragments.p/meson-generated_fragments-app.c.o src/fragments.p/meson-generated_fragments-utils.c.o src/fragments.p/meson-generated_fragments-torrent.c.o src/fragments.p/meson-generated_fragments-torrent-group.c.o src/fragments.p/meson-generated_fragments-torrent-manager.c.o src/fragments.p/meson-generated_fragments-torrent-model.c.o src/fragments.p/meson-generated_fragments-torrent-listbox.c.o src/fragments.p/meson-generated_fragments-settings-window.c.o src/fragments.p/meson-generated_fragments-torrent-row.c.o src/fragments.p/meson-generated_fragments-settings.c.o src/fragments.p/meson-generated_fragments-window.c.o -Wl,--as-needed -Wl,--no-undefined -Wl,--start-group /usr/lib64/libgtk-3.so /usr/lib64/libgdk-3.so /usr/lib64/libpangocairo-1.0.so /usr/lib64/libpango-1.0.so /usr/lib64/libharfbuzz.so /usr/lib64/libatk-1.0.so /usr/lib64/libcairo-gobject.so /usr/lib64/libcairo.so /usr/lib64/libgdk_pixbuf-2.0.so /usr/lib64/libgio-2.0.so /usr/lib64/libgobject-2.0.so /usr/lib64/libglib-2.0.so /usr/lib64/libhandy-1.so -lb64 -lutp -lminiupnpc /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/dht.a -lnatpmp -levent -lcurl -lcrypto -lssl -lutp /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libpthread.so -lz -ltransmission -Wl,--end-group /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(tr-utp.c.o): in function `incoming': (.text+0x4d): undefined reference to `UTP_GetPeerName' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: (.text+0x9d): undefined reference to `UTP_Close' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(tr-utp.c.o): in function `timer_callback': (.text+0x175): undefined reference to `UTP_CheckTimeouts' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(tr-utp.c.o): in function `tr_utpPacket': (.text+0x206): undefined reference to `UTP_IsIncomingUTP' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(net.c.o): in function `tr_netOpenPeerUTPSocket': (.text+0x11c3): undefined reference to `UTP_Create' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(peer-io.c.o): in function `io_close_socket': (.text+0xbe): undefined reference to `UTP_SetCallbacks' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: (.text+0xc7): undefined reference to `UTP_Close' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(peer-io.c.o): in function `tr_peerIoNew': (.text+0x5cd): undefined reference to `UTP_SetSockopt' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: (.text+0x5ec): undefined reference to `UTP_SetCallbacks' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: (.text+0x606): undefined reference to `UTP_Connect' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(peer-io.c.o): in function `tr_peerIoTryWrite': (.text+0xdcf): undefined reference to `UTP_Write' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(peer-io.c.o): in function `tr_peerIoTryRead': (.text+0x27c8): undefined reference to `UTP_RBDrained' /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.2.0/../../../../lib64/libtransmission.a(peer-mgr.c.o): in function `close_peer_socket': (.text+0x55c): undefined reference to `UTP_Close' collect2: error: ld returned 1 exit status ninja: build stopped: subcommand failed. ``` I'm not very experienced in this, but I think it is somehow related to the libutp library? https://github.com/bittorrent/libutp I built and installed it to my system, tried to add it as a dependency in meson.build, but it didn't work. Then I noticed there is an -DUSE_SYSTEM_UTP=OFF option in the transmission ebuild. Is it related? Tried to build it with this option enabled but without any success. Does it have to do something with the libtransmission.a library itself and its compilation? Reproducible: Always Steps to Reproduce: 1. Install all dependencies 2. git clone https://gitlab.gnome.org/World/Fragments 3. cd Fragments 4. meson build 5. cd build 6. ninja
See bug 807993 comment 11. If you manage to get everything working, patches would be welcome. But I'm not planning to spend any effort myself on this.
