Hi,

Thanks for your reply. I can try doing it from the sources myself.

Hi,

I'm currently using Log4cxx on a Suse 10.3, but I started from the
sources (compiling apr, apr-utils and log4cxx).

I don't have so many dependencies that you have (maybe because I
compiled apr and apr-utils in static ?) :
        linux-gate.so.1 =>  (0xffffe000)
        libexpat.so.1 => /lib/libexpat.so.1 (0xb7d04000)
        libuuid.so.1 => /lib/libuuid.so.1 (0xb7cff000)
        librt.so.1 => /lib/librt.so.1 (0xb7cf6000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0xb7cc4000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb7cac000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7ca8000)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7bba000)
        libm.so.6 => /lib/libm.so.6 (0xb7b95000)
        libc.so.6 => /lib/libc.so.6 (0xb7a62000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7a56000)
        /lib/ld-linux.so.2 (0x80000000)

Anyway, i don't find back the lib Berkeley DB (libdb4.8) in the list.

In case it could help,
Jean
