The current qtserialport requires udev unconditionally. The purpose of the sed in the is to ensure that is built independently of the Qt core installlation's udev status (dev-qt/qtgui[udev]). I suspect that build failure is occurring here due to relying on QMAKE_LIBS_LIBUDEV being automagically populated when it may not always. Could you please add the output of 'qlist dev-qt | grep gentoo | xargs grep udev'? (In reply to Michael Palimaka (kensington) from comment #9) > Could you please add the output of 'qlist dev-qt | grep gentoo | xargs grep > udev'? For the record, it looks like this on my testing devbox: > # qlist dev-qt | grep gentoo | xargs grep --color udev > /usr/lib64/qt5/mkspecs/gentoo/qmodule-qtcore.pri:QT.global_private.enabled_features = sse2 alloca_h alloca avx2 libudev network posix_fallocate reduce_exports reduce_relocations sql system-zlib testlib xml > /usr/lib64/qt5/mkspecs/gentoo/qmodule-qtcore.pri:QMAKE_LIBS_LIBUDEV = /lib64/libudev.so The presence of these entries are very suspicious given that I do not have qtgui (which is supposed to manage Qt core udev status) installed for this test. *** Bug 682896 has been marked as a duplicate of this bug. *** (In reply to Michael Palimaka (kensington) from comment #9) > The current qtserialport requires udev unconditionally.

Usually, that path is detected correctly, however in the report's setup (catalist?) it must be set as "qmodule-qtcore.pri:QMAKE_LIBS_LIBUDEV = /usr/lib64/libudev.so", as per log: x86_64-pc-linux-gnu-g++ -Wl,-O1 -Wl,--as-needed -Wl,--no-undefined -Wl,--version-script,QtSerialPort.version -Wl,--enable-new-dtags -shared -Wl,-Bsymbolic-functions -Wl,-soname,libQt5SerialPort.so.5 -o libQt5SerialPort.so.5.12.1 .obj/qserialport.o .obj/qserialportinfo.o .obj/qserialport_unix.o .obj/qserialportinfo_unix.o -lQt5Core -lpthread /usr/lib64/libudev.so Created attachment 580412 [details]
dev-qt:qtserialport-5.12.4-build-success.log
I wonder if this is still an issue with 5.12.4 (in overlay)?
I just built qtserialport-5.12.4, with eudev, on a stable testing install and noticed no issues.
(5.13 seems to be fine as well.)

I see two solutions: - add qtcore[udev] requirement - ZC solution: 's/$$QMAKE_LIBS_LIBUDEV/-ludev/' FYI, upstream fixed the issue, but I'm not sure how easy it would be to backport the patch.
