Libmodbus 3.1.4 & SDM 120c on ARM

[AWV7600]

Hello,

I 've got trouble while installing SDM on my Odroid (ARMv7). Installation of libmodbus 3.1.4 seems ok but SDM gives some errors. See the history below... What do you think about it ? Thanks by advance for your answer.

Libraries have been installed in: /usr/local/lib

If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the '-LLIBDIR' flag during linking and do at least one of the following:

• add LIBDIR to the 'LD_LIBRARY_PATH' environment variable during execution
• add LIBDIR to the 'LD_RUN_PATH' environment variable during linking
• use the '-Wl,-rpath -Wl,LIBDIR' linker flag
• have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for

more information, such as the ld(1) and ld.so(8) manual pages.
