一、问题描述

Ubuntu22.04下Anacodna3的qmake和Qt的qmake冲突问题

/usr/bin/ld: /lib/x86_64-linux-gnu/libcaca.so.0: undefined reference to `init_pair@NCURSESW6_5.1.20000708'

二、原因分析

检查问题，说 libcaca 有问题，查看该库的依赖问题

ldd /lib/x86_64-linux-gnu/libcaca.so.0

输入无问题

	linux-vdso.so.1 (0x00007ffc14d1d000)libslang.so.2 => /lib/x86_64-linux-gnu/libslang.so.2 (0x00007fbbde800000)libncursesw.so.6 => /lib/x86_64-linux-gnu/libncursesw.so.6 (0x00007fbbdebc2000)libtinfo.so.6 => /lib/x86_64-linux-gnu/libtinfo.so.6 (0x00007fbbdeb90000)libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fbbdeb74000)libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fbbde400000)libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fbbde719000)/lib64/ld-linux-x86-64.so.2 (0x00007fbbdecf9000)

则定位到是库的引用问题，这里的库应该是qt的环境库

home/zhy/anaconda3/lib/libQt5Gui.so /home/zhy/anaconda3/lib/libQt5Core.so

正确的库

/usr/lib/x86_64-linux-gnu/libQt5Widgets.so /usr/lib/x86_64-linux-gnu/libQt5Gui.so

三、解决办法

指定 qmake 即可

/usr/bin/qmake

make

编译则正常通过了

zhy@zhy-HP:~/libmpv/qt$ /usr/bin/qmake 
zhy@zhy-HP:~/libmpv/qt$ make
g++  -o qtexample qtexample.o moc_qtexample.o  -lmpv /usr/lib/x86_64-linux-gnu/libQt5Widgets.so/usr/lib/x86_64-linux-gnu/libQt5Gui.so /usr/lib/x86_64-linux-gnu/libQt5Core.so -lGL -lpthread
