Folks,
I apologize in advance if this should go to the users' mailing list...
We adopted log4cxx several years ago, building it against Redhat
Enterprise Linux 5.7, and using it with our product. Now a larger
corporate entity has begun pushing for our products to support RHEL7. We
have tried:
1) running the RHEL5.7 binary on a RHEL7 machine:
failure due to missing libraries (only newer named versions
of these libraries are installed on RHEL7 boxes)
2) rebuilding log4cxx on an RHEL7 box:
failure due to requiring specific versions of libraries (and
hence, differing headers)
Following up on the runtime failure messages, we find specific issues
with apr-util (for an example):
[donw@ostest lib]$ ldd libaprutil-1.so.0.2.2
linux-vdso.so.1 => (0x00007fff299fe000)
libgdbm.so.2 => not found
libdb-4.2.so => not found
libexpat.so.0 => not found
libapr-1.so.0 => /usr/lib64/libapr-1.so.0 (0x00007f08d7b73000)
libuuid.so.1 => /usr/lib64/libuuid.so.1 (0x00007f08d796d000)
librt.so.1 => /usr/lib64/librt.so.1 (0x00007f08d7765000)
libcrypt.so.1 => /usr/lib64/libcrypt.so.1 (0x00007f08d752e000)
libpthread.so.0 => /usr/lib64/libpthread.so.0 (0x00007f08d7311000)
libdl.so.2 => /usr/lib64/libdl.so.2 (0x00007f08d710d000)
libc.so.6 => /usr/lib64/libc.so.6 (0x00007f08d6d4c000)
/lib64/ld-linux-x86-64.so.2 (0x00007f08d7ee9000)
libfreebl3.so => /usr/lib64/libfreebl3.so (0x00007f08d6ace000)
Looking just for libdb-4.2.so, we see the relevant entries are
[donw@ostest lib]$ ls -l /lib64/libdb*
-rwxr-xr-x. 1 root root 1544688 Jan 24 2014 /lib64/libdb-4.7.so
-rwxr-xr-x. 1 root root 1846248 Jan 26 2014 /lib64/libdb-5.3.so
lrwxrwxrwx. 1 root root 12 Feb 3 23:40 /lib64/libdb-5.so ->
libdb-5.3.so
-rwxr-xr-x. 1 root root 1665128 Jan 24 2014 /lib64/libdb_cxx-4.7.so
lrwxrwxrwx. 1 root root 12 Feb 3 23:42 /lib64/libdb.so ->
libdb-5.3.so
Similar results exist for /usr/lib64.
It appears that just running the RHEL57 binaries on a standard RHEL7 box
is not an option. We also can't tell our customers "just load these
older libdb/other libraries".
So I guess my main question is, are there any plans on updating log4cxx
and its ancillary apr libraries to build/be compatible with RHEL7?
