NOTES FOR UNIX LIKE PLATFORMS
|
||
|
|
=============================
|
||
|
|
|
||
|
|
For Unix/POSIX runtime systems on Windows, please see NOTES.WIN.

Shared libraries and installation in non-standard locations
|
||
|
|
-----------------------------------------------------------
|
||
|
|
|
||
|
|
Binaries on Unix variants expect to find shared libraries in standard
|
||
|
|
locations, such as /usr/lib, /usr/local/lib and some other locations
|
||
|
|
configured in the system (for example /etc/ld.so.conf on some systems).
|
||
|
|
If the libraries are installed in non-standard locations, binaries
|
||
|
|
will not find them and therefore fail to run unless they get a bit of
|
||
|
|
help from a defined RPATH or RUNPATH. This can be applied by adding
|
||
|
|
the appropriate linker flags to the configuration command, such as
|
||
|
|
this (/usr/local/ssl was the default location for OpenSSL installation
|
||
|
|
in versions before 1.1.0):
|
||
|
|
|
||
|
|
$ ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl \
|
||
|
|
-Wl,-rpath,/usr/local/ssl/lib
|
||
|
|
|
||
|
|
Because the actual library location may vary further (for example on
|
||
|
|
multilib installations), there is a convenience variable in Makefile
|
||
|
|
that holds the exact installation directory and that can be used like
|
||
|
|
this:
|
||
|
|
|
||
|
|
$ ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl \
|
||
|
|
-Wl,-rpath,'$(LIBRPATH)'
|
