Hello,
I've installed ambertools using the anaconda method, and most of
binaries I've run have workd well. I did find what appears to be a bug
in the ambpdb program though. When I run ambpdb, I get the following
error:
====================================
ambpdb: error while loading shared libraries:
/home/haichit/miniconda3/conda-
bld/ambertools_1556345835936/work/lib/libcpptraj.so: cannot open shared
object file: No such file or directory
=====================================
When I run ldd on the binary to show where it's resolving the dynamic
libraries to, what I find is:
======================================
(base) ➜ anaconda3 ldd `which ambpdb`
linux-vdso.so.1 (0x00007ffd67b30000)
/home/haichit/miniconda3/conda-
bld/ambertools_1556345835936/work/lib/libcpptraj.so => not found
libstdc++.so.6 =>
/var/tmp/local/anaconda3/bin/../lib/libstdc++.so.6 (0x00007fc146eaa000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6
(0x00007fc146a5b000)
libgcc_s.so.1 =>
/var/tmp/local/anaconda3/bin/../lib/libgcc_s.so.1 (0x00007fc146e34000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6
(0x00007fc14666a000)
/lib64/ld-linux-x86-64.so.2 (0x00007fc146df9000)
======================================
This is in contrast to how libcpptraj.so is linked on another machine
where I've built amber from the source code:
======================================
nsg.asteroids ~> ldd (which ambpdb)
linux-vdso.so.1 (0x00007ffdb4b55000)
/home/nsg/bin/amber18/lib/libcpptraj.so (0x00007f250e321000)
libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007f250e0ff000)
libm.so.6 => /lib64/libm.so.6 (0x00007f250dfb9000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f250df9f000)
libc.so.6 => /lib64/libc.so.6 (0x00007f250ddd9000)
libgfortran.so.5 => /lib64/libgfortran.so.5
(0x00007f250db3a000)
libbz2.so.1 => /lib64/libbz2.so.1 (0x00007f250db24000)
libz.so.1 => /lib64/libz.so.1 (0x00007f250db0a000)
/lib64/ld-linux-x86-64.so.2 (0x00007f250eb46000)
libquadmath.so.0 => /lib64/libquadmath.so.0
(0x00007f250dac0000)
======================================
The library in question is present in the anaconda install:
======================================
(base) ➜ anaconda3 ls -l lib/*cpptr*
-rwxrwxr-x 2 nguerin nguerin 9128451 Apr 27 02:52 lib/libcpptraj.so
======================================
But ambpdb just isn't using it.
Thanks for any help or guidance you may be able to give!
Best regards,
Nate Guerin
