Hello,

I may be wrong but the above explanation sounds as if the build process may
include some static libraries (APR) into a shared library (log4cxx). Isn't that
wrong? Static libs are usually compiled without -fPIC, which is, AFAIK, required
for object code that goes into shared libs on at least some platforms. See for
example this discussion:

http://lists.debian.org/debian-mentors/2002/03/msg00172.html

(At least currently), it works here:

$ svn co http://svn.apache.org/repos/asf/logging/log4cxx/trunk log4cxx
A    log4cxx/xdocs
A    log4cxx/xdocs/src
A    log4cxx/xdocs/src/performance.xml
A    log4cxx/xdocs/src/team.xml
...

Maybe just retry it ...

build problem

Hi
I am trying to build log4cxx on cygwin. It gets compiled but I get this
error when it links. Can anyone suggest what I should do?
thanks a lot

log4cxx 0.9.8

Yes, 0.9.8 implies binary compatibility with 0.9.7 which wasn't the  
case.  The forthcoming version will be 0.10.0.

possible race condition with forked process

Hello,

I'm essentially calling LOG4CXX_INFO in a child process between a call to
fork() and a call to execv() on FreeBSD 6.0.  The child process blocks
indefinitely maybe 1 in 4 times upon calling the LOG4CXX_INFO macro.  If it
doesn't block there, log4cxx calls after the execv work fine.  If I remove
the call between the fork and execv, then I never encounter the problem.

I was using 0.9.7, so I was hoping the latest from SVN would fix my issue.
However, upgrading did not improve the situation.  I am interested to try
this on my Linux machine, but it will take some time to get the latest
log4cxx installed on there as well.

Would there be any race conditions involved in calling LOG4CXX_INFO using
the parent's logger object between a fork and exec?  I know the parent's
memory is supposed to be copied for the child after the fork, rather than
shared, but I can imagine something could get broken in the copy-on-write,
or maybe mutex initialization, or even static data.

Thanks!
