Hi Everyone,
I am trying to compile net-snmp 5.8 version on my ARM Yocto platform and I
am getting error regarding "undefined reference to ceil" function. I am
getting this error only when I pass "--enable-blumenthal-aes" flag during
configuration. If I compile without "--enable-blumenthal-aes" flag then it
compiles without any error.
I confirmed that math library (libm.so) is on path still I am getting this
error. I have notice that yocto platfrom is adding "-Wl,--as-needed" flag
during compilation. If I remove "-Wl,--as-needed" from below last failed
compilation command then it executes without any error.
It looks like that net-snmp 5.8 version is broken with "--as-needed" option
when "--enable-blumenthal-aes" configuration is enabled. Please let me know
how I can resolve this error.
Below are last lines of compilation with error.
