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 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 "Unknown compiler version -

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.
