From: ThorstenB Date: Sun, 13 Nov 2011 14:37:49 +0000 (+0100) Subject: Replace OpenThreads with SGThread to avoid useless OSG dependency. X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=dfbdcc1bf04b8fbc1ee7be7d1680dc7296eecaa0;p=simgear.git Replace OpenThreads with SGThread to avoid useless OSG dependency. Untangle SG subsystems by replacing direct TileCache call with callback. --- diff --git a/simgear/scene/tsync/terrasync.cxx b/simgear/scene/tsync/terrasync.cxx index 800f278a..70fd13cc 100644 --- a/simgear/scene/tsync/terrasync.cxx +++ b/simgear/scene/tsync/terrasync.cxx @@ -59,9 +59,7 @@ #include #include #include -#include #include -#include #ifdef HAVE_SVN_CLIENT_H # ifdef HAVE_LIBSVN_CLIENT_1 @@ -141,7 +139,7 @@ public: /////////////////////////////////////////////////////////////////////////////// // SGTerraSync::SvnThread ///////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////// -class SGTerraSync::SvnThread : public OpenThreads::Thread +class SGTerraSync::SvnThread : public SGThread { public: SvnThread();
