This article mainly introduces how to solve the problem of Unixbench installation error information, the article is very detailed, has a certain reference value, interested friends must read it!

Operating environment:

Ubuntu 16.04.3 x86_64

When you install and run Unixbench under Ubuntu, the error message is as follows

Gcc-o. / pgms/ubgears-DTIME-Wall-pedantic-ansi-O2-fomit-frame-pointer-fforce-addr-ffast-math-Wall. / src/ubgears.c-lGL-lXext-lX11 / usr/bin/ld: / tmp/ccnTgDEZ.o: undefined reference to symbol 'sincos@@GLIBC_2.2.5' / / lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status Makefile:240: recipe For target 'pgms/ubgears' failed make: * * [pgms/ubgears] Error 1

By consulting the data, because mathematical functions are used in ubgears.c, and the corresponding mathematical functions can not be found in the actual run time, you only need to display the library of calling function functions, and add-lm after GL_LIBS in Makefile.

Use ld-v to view the ld tool version

Starting with binutils2.22, ld turns on-no-copy-dt-needed-entries by default, so that ld no longer automatically parses the linked lib recursively, but needs to be specified by the user one by one.
