I've DL'ed and installed boost to gain access to the serialization capabilities. Here is the source code I'm trying to compile to test the install. Its the serialization equivalent of a "hello world" app.: //////////////////////////////////////////////// #include <iostream> #include <fstream> #include <boost/archive/text_oarchive.hpp> using std::cout; using std::endl; class DataHold { private: friend class boost::serialization::access; template <class Archive> void serialize(Archive & ar, const unsigned int version) { ar & data1; ar & data2; } int data1; int data2; public: DataHold(){} DataHold(int d1, int d2):data1(d1),data2(d2){} void dump() { cout << data1 << ":" << data2 << endl; } }; int main() { DataHold dt1(7,9); std::ofstream ofs("holddata.dh"); boost::archive::text_oarchive oa(ofs); oa << dt1; ofs.close(); } //////////////////////////////////////////// When I try to compile I get this: In file included from /usr/local/include/boost/config.hpp:35, from /usr/local/include/boost/archive/text_oarchive.hpp:22, from boostTest.cpp:3: /usr/local/include/boost/config/compiler/gcc.hpp:92:7: warning: #warning

Now, I've tried compiling some of the sample code that comes with the boost package ... some compiles just fine, some does not and gives me similar errors to what I show above. I have no idea what these errors mean nor do I understand how to make them go away. My platform info: i386-redhat-linux gcc version 4.0.0 20050423 (Red Hat 4.0.0-2) To install I did: 1) DL'ed and untarred boost_1_32_0.tar.bz2 2) installed the .rpm'ed boost-jam-3.1.10-i386.rpm 3) chdir boost_1_32_0 4) bjam "-sTOOLS=gcc" install Here I got a bunch of "unknown compiler" messages but the install seemed to go ok other than that. I checked /usr/local/include/boost-32/boost and found all of the .hpp files and subdirs including 'serialization'. I also checked /usr/local/lib and found all of the .so and .a files (The wserialization and serialization .so files were notably absent) I searched all over for the .so files but could not locate them anywhere in my filesystem. I suspect this is the main snag I'm confronting. 5) ln -s /usr/local/include/boost-32/boost /usr/local/include/boost 6) added /usr/local/lib to /etc/ld.so.conf 7) ldconfig Then I tried to compile the source I presented earlier. Any help resolving the resulting errors would be greatly appreciated. Thanks, Mike ____________________________________________________ Sell on Yahoo! Auctions – no fees.
