(sorry for the cross-post but httpd-trunk and APR are now so entwined that its required)...
OK... I've been playing around with building httpd-trunk on Linux and I've been having troubles left and right (using the 1.4 branches of both apr and apr-util installed right in ./srclib)... First of all, Ubuntu 8.10 can't even get past a top level ./buildconf (likely due to libtool issues (2.2.4)... But Ubuntu 9.10 dies when getting to build apr-util due to expat issues (can't find the system installed version and the bundled version's config/make is toast)... checking Expat 1.95.x... no checking old Debian-packaged expat... no checking old FreeBSD-packaged expat... no checking Expat 1.0/1.1... no setting LDFLAGS to "-L/usr/local/lib" adding "-I/usr/local/include" to CPPFLAGS checking Expat 1.95.x in /usr/local... no nulling LDFLAGS removed "-I/usr/local/include" from CPPFLAGS configuring package in xml/expat now checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking target system type... i686-pc-linux-gnu /home/jim/src/asf/code/dev/httpd-trunk/srclib/apr-util/xml/expat/configure: line 3321: syntax error near unexpected token `lt_decl_varnames,' /home/jim/src/asf/code/dev/httpd-trunk/srclib/apr-util/xml/expat/configure: line 3321: `lt_if_append_uniq(lt_decl_varnames, SED, , ,' configure failed for xml/expat For those who are working on httpd trunk and Linux, what are you using?
