Thanks, Ken. I think this is easier than adding another option to Moses
if we can understand the output. The ldd manpage says "ldd prints the
shared libraries required by each program or shared library specified on
the command line." I assume "shared libraries" means not statically
linked?
Here's the output on the moses I just built with today's github
updates. The log output reported exit code 0 for all lines with "g++
-static".
tahoar@library1:~$ ldd `which moses`
linux-vdso.so.1 => (0x00007fffa2954000)
librt.so.1 => /lib/librt.so.1 (0x00007f818aa7b000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f818a767000)
libm.so.6 => /lib/libm.so.6 (0x00007f818a4e3000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f818a2cc000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00007f818a0af000)
libc.so.6 => /lib/libc.so.6 (0x00007f8189d2b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f818aca7000)
Is this what I should expect if all of the libboost libraries are
statically linked? I think so because there are no references to the
lboost_* or lz libraries in the log file.
