Hello, I am developing an application that is based on OpenSSL. I am developing it on Mac OS X (10.5) but I have to build it on other environments so I would like to use autotools. I am a newbie to autoconf and autotools. I spent some time reading tutorials and Autobook (http://sources.redhat.com/autobook/) and while I am able to build a hello world project with autoconf, I have some difficulties building and linking my project againts OpenSSL. I would be very grateful if you provide any hints or pieces of advise. Here is more information about my project. Its sources live in src/ subdirectory. I have configure.in in its top-level directory: $ cat configure.in # -*- Autoconf -*- # Process this file with autoconf to produce a configure script. AC_INIT([cryptoexamples], [0.1], [rambiusparkisanius@xxxxxxxxx]) AC_CONFIG_AUX_DIR(config) AC_CONFIG_SRCDIR([src]) AC_CONFIG_HEADERS([config.h]) AM_INIT_AUTOMAKE(cryptoexamples, 0.1) # Checks for programs. AC_PROG_CC AC_PROG_RANLIB # Checks for libraries. AC_CHECK_LIB(ssl, SSL_library_init) # Checks for header files. # Checks for typedefs, structures, and compiler characteristics. # Checks for library functions. AC_OUTPUT(Makefile src/Makefile) I also have Makefile.am and src/Makefile.am: $ cat Makefile.am SUBDIRS = src $ cat src/Makefile.am bin_PROGRAMS = countnb countnb_SOURCES = countnb.c lib_LIBRARIES = libseedprng.a libseedprng_a_SOURCES = seed_prng.c Now my questions are: 1) The default locations of openssl headers and libs are /usr/include and /usr/libs on Mac OS X. However, I have newer version of openssl in /opt/local with headers in /opt/local/include and libs in /opt/local/lib. How to instruct autotools to use the version in /opt/local on Mac OS X? 2) In configure.in I make a check for openssl availability using the macro AC_CHECK_LIB(ssl, SSL_library_init) Later, when I run ./configure I get the message checking for SSL_library_init in -lssl... yes How can I instruct autoconf to fail if openssl is not found (in /opt/local)? 3) In src/Makefile.am I am trying to build libseedprng.a with lib_LIBRARIES = libseedprng.a libseedprng_a_SOURCES = seed_prng.c How can I instruct it to link it against ssl and crypto libraries; that is how can I pass -lssl and -lcrypto options to the linker? Thank you in advance for your responses.
