Hi all, I am trying to install tcltls libaries (http://tls.sourceforge.net) on a SL6.1 x86_64 laptop, but I can't. When I launch configure returns me this error: ./configure --prefix=/opt/tls --libdir=/opt/tls/lib --disable-threads checking for correct TEA configuration... ok (TEA 3.6) checking for Tcl configuration... configure: WARNING: Can't find Tcl configuration definitions In config.log appears this: $ ./configure --prefix=/opt/tls --libdir=/opt/tls/lib --disable-threads ## --------- ## ## Platform. ## ## --------- ## hostname = lapsl61.homelab.net uname -m = x86_64 uname -r = 2.6.32-131.12.1.el6.x86_64 uname -s = Linux uname -v = #1 SMP Wed Aug 24 13:32:23 CEST 2011 /usr/bin/uname -p = unknown /bin/uname -X = unknown /bin/arch = x86_64 /usr/bin/arch -k = unknown /usr/convex/getsysinfo = unknown hostinfo = unknown /bin/machine = unknown /usr/bin/oslevel = unknown /bin/universe = unknown PATH: /usr/local/sbin PATH: /usr/local/bin PATH: /sbin PATH: /bin PATH: /usr/sbin PATH: /usr/bin PATH: /root/bin ## ----------- ## ## Core tests. ## ## ----------- ## configure:1328: checking for correct TEA configuration configure:1347: result: ok (TEA 3.6) configure:1473: checking for Tcl configuration configure:1583: WARNING: Can't find Tcl configuration definitions I have installed tcl-devel and openssl-devel libraries needed to install this library, but it doesn't works ... On a SL6.1 i386 workstation I have installed without problems ... Any idea?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com
