ivykis and libmongo-client are not available for Cygwin. Is there no way around using these libs by using conditional compilation?
There's a way, mongodb can be disabled using --disable-mongodb configure option (but is enabled by default with the bundled libmongo-client library).
ivykis is not so simple, syslog-ng core depends on that heavily. ivykis is compiled as a static library (with -fPIC) and then linked into libsyslog-ng.so
The staticlib is just a convenience library, however I'd like that to be created by the ivykis configure/automake stuff, and would like to avoid having to rewrite the build system for ivykis. Also, I wouldn't want to install ivykis (as a shared object) from the syslog-ng tree, as I could perhaps break people's setup if ivykis becomes more widely available. (e.g. installed on the system).
Do you perhaps have an idea how to solve that differently?
If you don't provide a shared ivykis lib, building libsyslog-ng.so on Cygwin will break. Assuming ivykis builds on Cygwin, which nobody tested yet either... Off the top my head I can see two ways around the shared/static problem. - Add the ivykis source files to libsyslog_ng_la_SOURCES. - Don't link libsyslog-ng.so against ivykis at all. Instead, build ivykis as a module which gets installed into /usr/lib/syslog-ng and use dlopen/dlsym to call its functions.
Btw., I'm seeing a lot of
foo.y: warning: X nonterminals useless in grammar foo.y: warning: Y rules useless in grammar
messages. Aren't the grep calls in build/lex-rules.am wrong?
grep -E -v "warning: (nonterminals|rules) useless in grammar
instead of
grep -E -v "warning: (nonterminal|rule) useless in grammar
? Or does the message depend on the version of yacc/bison used, perhaps?
Well, it seems to matter which bison version you are using. 3.3 has a fix for this (where it accepts both the pural and the singular forms).
Any chance to fix this in 3.2, too? It's just adding a "s?" to the regex: grep -E -v "warning: (nonterminal|rule)s? useless in grammar" Thanks, Corinna -- Corinna Vinschen Cygwin Project Co-Leader Red Hat
