autoconf

I am having a bear of a time getting autoconf to check for the presence of a particular header file. Let's call the header dependency "inky.h", and let's say that inky is a library that was installed (seperately) with the prefix set to "/usr/local". This put "inky.h" in /usr/local/inky/inky.h and libinky.so in /usr/local/lib. Now, I'm trying to verify the presence of inky.h in my applications configure.ac as follows: dnl # Setup temp LDFLAGS and look for inky library/header LDFLAGS_SAVE=${LDFLAGS}; CPPFLAGS_SAVE=${CPPFLAGS}; dnl # Look for inky on the user specified inky install path LDFLAGS =

fcntl() uses struct flock structure to define and check file locks. Unfortunately, on different Unix systems the fields in this structure are in different order. Does anybody know how one could check for it with autoconf or at least check if the structure is in specific format (e.g. the question would be - does the struct format matches the Linux format)? You can use this autoconf macro to find if a certain member of struct flock exists: AC_CHECK_MEMBERS([struct flock.l_type],[],[],[[#include <fcntl.h>]]) Github has a variety of autoconf files you can look at for additional ideas by searching

I'm creating a project and using GNU Autoconf tools to do the configuring and making. I've set up all my library checking and header file checking but can't seem to figure out how to check if an executable exists on the system and fail if it doesn't exist. I've tried: AC_CHECK_PROG(TEST,testprogram,testprogram,AC_MSG_ERROR(Cannot find testprogram.)) When I configure it runs and outputs: Checking for testprogram... find: `testprogram. 15426 5 ': No such file or directory but does not fail. Try this which is what I just lifted from a project of mine, it looks for something called quantlib-config

So after I ran libtool and got out a libfoo.lo and foo.o file from my library source, how do I convert the libfoo.lo file into a normal Linux shared library, like libfoo.so.1.0.0 so I can install and link to it on my target system? From the outputs mentioned in the question, it looks like you ran libtool with --mode=compile mode. You will need to run libtool again with --mode=link to produce .a and .so libraries. libtool is just a simple wrapper for gcc, ln ar and ranlib which is needed to produce libraries. All it does is run gcc adding the necessary options to ensure that your static and

I have a project with autotools: automake, autoconf. I want to prohibit make from remaking files configure , Makefile.in , etc; just to do compile job. Some of files are edited by hand, and I know that I should not to do this. (Or the project was updated from CVS with all generated files stored in CVS). But at the moment I have no correct version autotools installed. What must be modification times of this files (which must be newer/older): aclocal.m4 configure.in confdb/ax_prefix_config_h.m4 Makefile.am Makefile.in Makefile configure config.status Or: what sequence of touch commands must I do
