Ran into another issue with my netrek-server move to cmake.
Attempting to link with an internal library gives me a whole bunch of
"non_lazy_ptr" linking errors:
Linking C executable trimscores
Undefined symbols:
"_Cambot_out", referenced from:
_Cambot_out$non_lazy_ptr in libnetrek.a(getpath.o)
"_NoCount_File", referenced from:
_NoCount_File$non_lazy_ptr in libnetrek.a(getpath.o)
"_Global", referenced from:
_Global$non_lazy_ptr in libnetrek.a(getpath.o)
Spent alot of time poking around google until I found this url:
http://software.intel.com/en-us/articles/intelr-fortran-compiler-for-mac-os-non_lazy_ptr-unresolved-references-from-linking/
Summary
of the above url says that when you "ranlib" you really should "ranlib
-c" and makes reference to the libtool manpage (more on this later).
If I 'ranlib -c ntserv/libnetrek.a' and make
$ make
<snip>
Linking C executable trimscores
[ 98%] Built target trimscores
Things work.
First question, how to I add "-c" to ranlib evocation?
I build libnetrek via the ADD_LIBRARY as noted below:
ADD_LIBRARY (netrek STATIC
advertise.c
alarm.c
<snip>
warning.c
)
Which generates this command line:
/usr/bin/ar cr libnetrek.a CMakeFiles/netrek.dir/advertise.o
CMakeFiles/netrek.
dir/alarm.o <snip> CMakeFiles/netrek.dir/warning.o
/usr/bin/ranlib libnetrek.a
My gut tells me to change CMAKE_RANLIB but maybe a change the ADD_LIBRARY?
My research on ranlib lead me to libtool and the libtool manpage. On
osx-10.5.7 (all I have access to) the libtool manpage states:
" Libtool with -static is intended to replace ar(5) and ranlib.
For backward compatibility, ranlib is still available, and it supports
universal files. "
To ultimately, the ADD_LIBRARY should be changed to libtool. Just
passing that information along.
Thanks.
