Re: [naviserver-devel] --enable-rpath

[Gustaf N. <ne...@wu...>]

Hi David,

When i add the following two lines

     echo "---TCL_CC_SEARCH_FLAGS=$TCL_CC_SEARCH_FLAGS 
CC_SEARCH_FLAGS=$CC_SEARCH_FLAGS"
     echo "---TCL_LD_SEARCH_FLAGS=$TCL_LD_SEARCH_FLAGS 
LD_SEARCH_FLAGS=$LD_SEARCH_FLAGS"

before the setting of CCRFLAG and LDRFLAG on ubuntu (12.04.5 LTS), i see
on the console

    ---TCL_CC_SEARCH_FLAGS=-Wl,-rpath,${LIB_RUNTIME_DIR} 
CC_SEARCH_FLAGS=-Wl,-rpath,${LIB_RUNTIME_DIR}
    ---TCL_LD_SEARCH_FLAGS=-Wl,-rpath,${LIB_RUNTIME_DIR} 
LD_SEARCH_FLAGS=-Wl,-rpath,${LIB_RUNTIME_DIR}

i.e., CC_SEARCH_FLAGS is the same as TCL_CC_SEARCH_FLAGS, etc.
i would assume that this is on your system different. It looks to me as if
the TCL_* variants should be used, since these are tailored for Tcl.

The TCL_* variables are set in the used tclConfig.sh. Which tclConfig.sh 
are you using?
is it a "private" one or the Debian one?

My suspicion is that some distros do not like the search-flags and clear 
it...
