James Peach created TS-4047:
-------------------------------
Summary: multiple -rpath options are not handled correctly
Key: TS-4047
URL: https://issues.apache.org/jira/browse/TS-4047
Project: Traffic Server
Issue Type: Bug
Components: Build
Reporter: James Peach

Using TS_ADDTO to add the custom locations of libraries results in incorrect
"-rpath" directive to the linker. This is because TS_ADDTO creates a unique
list of tokens that it adds to its target. E.g.,
./configure --with-openssl=/usr/local/openssl --with-zlib=/usr/local/zlib
the above should result in
LIBTOOL_LINK_FLAGS: -rpath /usr/local/openssl/lib /usr/local/zlib/lib
The absence of "-rpath" in front of the second path causes an error in the
linker!
This is fixed by introducing a new macro TS_ADD_RPATH_TO that takes a path and
adds it with the "-rpath " prefix.
Also added influential environmental variable RPATH that can be used to give a
base value for the rpath. So, the following
./configure --with-openssl=/usr/local/openssl --with-zlib=/usr/local/zlib
RPATH=/foo
will result in
LIBTOOL_LINK_FLAGS: -rpath /foo -rpath /usr/local/zlib/lib -rpath
/usr/local/openssl/lib
