Re: configure: error: cannot run test program while cross compiling (arm linux uclibc)

[Martin Pala]

Hi,

the configure error during cross-compilation occurs because of the 
AC_RUN_IFELSE which tries to execute the test program for setjmp() and 
vsnprintf() C99 compliance. The problem will be fixed in the next Monit release.

Regarding the geloadavg() problem - your libc probably doesn't have the 
geloadavg. It is present in glibc since version 2.2, but some libraries which 
are usually used on embedded systems like uclibc doesn't implement 
getloadavg(). Workaround could be to modify the getloadavg_sysdep() in 
src/process/sysdep_LINUX.c - either implement the functionality on top of 
/proc/loadavg or if you don't need to test load average, remove the getloadavg 
call or add dummy getloadavg function or macro.

For the next Monit release we will implement the getloadavg_sysdep() for LINUX 
on top of /proc/loadavg => it won't require the libc support for it and will 
work fine with uclibc and similar libraries.

Regards,
martin
