Today, there should be much less complexity as the systems are more alike than different.

Autotools Mythbuster | Hacker News

Doesn’t clang work on Windows these days? Not all symbols defined within a shared object need to be exported, though. The silent rules are turned off by default, and the user has to enable them when building with one of the following two methods: When I was building packages for the Fedora MinGW Windows cross compiler[1] project, it was mostly trivial to get things working if the package used autotools or cmake, and an impossible nightmare for everything else.

Rules that don’t use full relative paths for targets and dependencies could be fouled up by stray files left around. Then regression-test it on the other targets, do any necessary tweaking and commit. To do that you can use the following snippet of code, for instance: Share Point Certification Review.

Before entering the details on how you use this tool, though, let’s look into something else: There’s no magic, it’s a complicated problem, with only complicated solutions. MichaelMoser on Dec 17, While this did find the whereabouts of headers, it included no information regarding their usability.


Also, the blog posts suffer from their nature: This is the case for compilers, debuggers, profilers and analyzers and other tools in general.

Autotools Mythbuster: so why do we have three projects?

What will this knowledge base do now? The golden idea in autotools is test for features not for versions.

Learning Android Application Testing. The tool has, of course, limitations; if a tool is missing, which is required to build either an intermediary, or final target which is not already present in the source tree, the build cannot proceed. This causes a phenomenon of “bit-rotting”, similar autoools the one caused by compilers and interpreters on source code: If things happen to build, they might not run properly.

Sorry, I don’t follow. There myhbuster has to be an error message if none at all of those is available. For distributions like Gentoo Linux that build on users’ systems, this situation is actually problematic and has to be resolved to properly package the software [ GentooAutomagic ].

One of the hardest part during the development of a library package is handling of version information, as it relates to the binary interface exposed by said libraries and is, thus, governed by those rules rather than what is a more human readable release version.

The system where the build process is being executed. A solution can be no simpler than the essential complexity of the problem it is solving.

I think so, if you pre-generate the build files for every platform and distribute them all in the tarball. In turn bogus results can create multi-layer failures that are also difficult to debug unless it is known that the cache was polluted. Eventually, alternative, slimmer macros might be looked up at the Autoconf archive.


It is thus of the utmost importance to not rely on the behaviour of these versions. For instance take the following fragment: The compiler output is If you want to generate two object files with two different settings, you have to myfhbuster two rules.

Since each option or option group might require a different explanation in different contexts, you can use the following list as a reference for them. The high level ideas are solid. I don’t know Autotools, but I find the CMake workflow to be tolerable. Since each of these scripts used a different interface, they usually came with their own custom macro to call the script and store the resulting information in a variable.

Some of the terms used throughout the guide are not of common usage, but are almost always mythbusetr to refer to simple concepts. In the end, I didn’t even manage to do proper checks for built files. But on systems following more or less the good practice, there will be no problem at all.

This will also be used as message during the configure checks: The other part wants to scratch my eyes out with a rusty fork. Tpo -c -o hellow. You can also check for multiple packages at the same time, by listing one after the other separated by whitespace.
