This is to discuss a possible improvement to ldd, a tool used to check
the linkage of a dynamically linked library or an executable.
While on Linux and Solaris (the latter from vague memories) an
unresolved link is duly printed by ldd, and the same is true for its
macOS' rough equivalent otool, on OpenBSD ldd just errors out like this:
$ ldd semigroups.so
semigroups.so:
Cannot load specified object
semigroups.so: exit status 1
If I tell it to look in a non-standard location, like this, it works:
$ LD_LIBRARY_PATH=/home/dima/lib ldd semigroups.so
semigroups.so:
Start End Type Open Ref GrpRef Name
00000c2788ba5000 00000c278abbd000 dlib 2 0 0

00000c27c1bd1000 00000c27c1c02000 rlib 0 2 0
/usr/lib/libm.so.10.1
Would there be interest in improving ldd on OpenBSD in this aspect?
Best,
Dima
