Thanks - that was very helpful Gustaf.
I'm using the Debian tclConfig.sh which does indeed clear those variables.
# Flags to pass to ld, such as "-R /usr/local/tcl/lib", that tell the
# run-time dynamic linker where to look for shared libraries such as
# libtcl.so. Used when linking applications. Only works if there
# is a variable "LIB_RUNTIME_DIR" defined in the Makefile.
TCL_CC_SEARCH_FLAGS=''
TCL_LD_SEARCH_FLAGS=''
Debian does discourage the use of rpath in general except in the following
case which I think applies in this instance:
https://wiki.debian.org/RpathIssue
"Currently, the only generally accepted use of this feature in Debian is to
add non-standard library path (like /usr/lib/<package>) to libraries that
are only intended to be used by the executables or other libraries within
the same source package."
So I can understand why Tcl8.5 doesn't have rpath's set in tclConfig.sh on
Debian.
Which would be the best way to include an rpath to the private naviserver
libraries (libnsdb.so, libnsd.so, libnsthread.so etc.) during the
Naviserver build so the nsd binary can find them?
It seems strange that I would need to change the TCL_*_SEARCH_FLAGS to
achieve this.
