I think i found the problem:in the <LnetPackage>\lazaruspackage\lib\<target> - folder is an old copy of openssl.o and openssl.ppu which conflicts with the fcl.and in the <LnetPackage>\lib - folder there is an old openssl.pas - file which is found prior to the fcl.Solution:Delete all files in <LnetPackage>\lazaruspackage\lib\<target>and delete <LnetPackage>\lib\openssl.pas (not longer needed in 0.6.6)Do a clean compile.that worked for me ...@GetMem: i think you did a clean checkout of the trunk-lnet so you had no problems ...@Moderator: Please rename the topic and/or move it to the correct forum, because it's about the 3rd party package LNet causing the problems.
