I cannot compile nxlog on Solaris. On configure i got: checking for apr_socket_create in -lapr-1... no configure: error: libapr-1 not found If I have APR in /usr/apr etc, I am trying: ./configure CFLAGS="-I/usr/apr/1.3/include -I/usr/apr-util/1.3/include" LDFLAGS="-L/usr/apr/1.3/lib/sparcv9 -L/usr/apr-util/1.3/lib/sparcv9" --with-apr=/usr/apr/1.3/ --with-included-apr --prefix=/export/home/user/compiled And there is the same.
