ERROR:libx265.so.51: undefined reference to '__sqrtf_finite' so i can't compile the program correctly, i hope for somebody can help me, thank you

[zhujian]

i use T2080RDB to compile the program x265. in the directory x265->build->README.txt,     i follow the README.txt saying. first, Use cmake to generate Makefiles: cmake ../source; second, build x265:         make.            but during the make operating,There appears to be a problem. 

libx265.so.51: undefined reference to `__sqrtf_finite'

libx265.so.51: undefined reference to `__sqrt_finite'

collect2: error: ld returned 1 exit status

CMakeFiles/cli.dir/build.make:261: recipe for target 'x265' failed

make[2]: *** [x265] Error 1

CMakeFiles/Makefile2:91: recipe for target 'CMakeFiles/cli.dir/all' failed

make[1]: *** [CMakeFiles/cli.dir/all] Error 2

Makefile:116: recipe for target 'all' failed

i hope someone can help me, thank you very much!!!

Hello Jian Zhu,

The function __sqrtf_finite should be provided in libm libarary. Did you include it in your Makefile?

Would you please share your Makefle?

Have a great day,
Yiping
