I'm attempting to build nxlog with some updated libraries: Latest APR (1.5.2) Non-Heartbleed vulnerable OpenSSL sources PCRE 8.37 Zlib 1.2.8 After building all the dependencies I'm a little stuck on getting nxlogs to build, specifically I'm stuck on the step where I run ./configure At first it couldn't find apr-1-config, so I added /local/apr/bin to the path. Then it couldn't fine libapr-1 so I added /local/apr/lib to the path, this is where the problems started. When APR built there wasn't a "libapr-1" file in /local/apr/lib, only libapr-1.a, libapr-1.la, libapr-1.dll.a. Did I build APR incorrectly? I'm trying to build this on windows List of steps to get where I am: 1. Install MINGW using MinGW Installation Manager Add packages: mingw-developer-toolkit mingw-base mingw-expat bin mingw32-libexpat dev msys-libopenssl dev msys-automake msys-autoconf Setup msys fstab (c:/mingw     /mingw) 2. Install Python (2.5) 3. Add Python and mingw to system path (C:\Python25;C:\MinGW\bin;C:\MinGW\msys\1.0\bin) 3. Get and build APR source (I could not get APR iconv to compile) Download: http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.11.tar.gz http://mirror.nexcess.net/apache//apr/apr-1.5.2-win32-src.zip http://mirror.nexcess.net/apache//apr/apr-util-1.5.4-win32-src.zip http://sourceforge.net/projects/pcre/files/pcre/8.37/pcre-8.37.zip/download http://zlib.net/zlib128.zip Build: Extract all files to c:\mingw\msys\1.0\src Compile libiconv cd libiconv-1.11 ./configure CFLAGS="-O2 -s -mms-bitfields -march=i686" CXXFLAGS="-O2 -s -mms-bitfields -march=i686" make && make install Compile APR cd apr ./buildconf   ./configure CFLAGS="-O0 -s -mms-bitfields -march=i686" CXXFLAGS="-O0 -s -mms-bitfields -march=i686" make && make install cd ..

Compile ZLIB cd zlib-1.2.8 make -f win32/Makefile.gcc Compile nxlog cd nxlog-ce-2.8.1248 ./configure This is where the problems began. First it couldn't find apr-1-config. Fixed by adding /local/apr/bin to path. Now it can't find libapr-1, addint /local/apr/lib to the path doesn't help. There is no libapr-1 file in the MinGW directory tree. Ideas?   -pacmanwa
