Hello, I get the following result when i ldd my shared library in a target computer: $> ldd /usr/lib/libCVTJavaInterface.so /usr/lib/libCVTJavaInterface.so: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/lib/libCVTJavaInterface.so) linux-gate.so.1 => (0xffffe000) libcvt.so => /usr/lib/libcvt.so (0xb7e95000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7dab000) libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7d84000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7d78000) libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7c37000) libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7c33000) /lib/ld-linux.so.2 (0x80000000) I have the following files in the target computer: lrwxrwxrwx 1 root root 18 2007-10-17 10:00 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.8 -rw-r--r-- 1 root root 929648 2007-03-02 21:51 /usr/lib/libstdc++.so.6.0.8 I have the following files in my development computer: gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7) /usr/lib/libstdc++.so.5 -> libstdc++.so.5.0.7 /usr/lib/libstdc++.so.5.0.7 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.9 /usr/lib/libstdc++.so.6.0.9 What can i do? One option i think is to static compile the libstdc++ library in my shared library. what is the instruction to do that? thanks in advance, Herbert _________________________________________________________________ News, entertainment and everything you care about at Live.com.
