Hi all
Just a few words on the matter (not at all trying to be complete), but I try to summarize what I've learned, that might help figuring out some issues:
- Check, if there is a README[.txt] or INSTALL and read it. Often it
contains some hints about dependencies and how to configure/compile the source package correctly.
- make sure that ./configure runs through successfully. This means, that
if something is required but not found, you probably need to install 'it' or tell the configure script where to find 'it'.
- sometimes there is no ./configure script, because it is supposed to be
generated. Sometimes you find an 'autogen.sh' script, that will do that for you. Sometimes you're supposed to that yourself by performing: $ aclocal $ autoconf You will quickly find out, whether this is the way to go, since aclocal and autoconf will tell you, if they didn't find the necessary files. If they don't, you're probably not supposed to use this tools in order to create a ./configure script.
- Sometimes no ./configure is used at all and something needs to be
compiled by simply doing $ make At the least there needs to be a 'makefile', which is a script that is executed by 'make'. Sometimes this makefile needs to be adapted to point to the correct headers of a certain dependency.
- Only if the ./configure step before (if there is one at all) did run
successfully and all the headers are found, really _only_ then you should proceed and do 'make'.
- If the make process didn't run successfully, it usually ends with an
error. If you see an error appearing the end of the output, you can be sure, that something went wrong. The reason might be found further up in the output. Usually the initial reason can be found in the first 'error' message. Often it is something like: bla.h: No such file or directory This can have various reasons with various solutions. The file 'bla.h' might not be installed at all. Or it is installed at a location that is not found by make or your sources point to a different location. On debian based systems you can install apt-file and after an initial 'sudo apt-file update' you can search, which package contains 'bla.h': $ apt-file search bla.h Often the solution is simply to install the package that comes with 'bla.h'. Then you can try 'make' again.
- If the error says something else, then might be the time to google for
the problem (try to google the first line with the 'error'. Often, it is a problem with versions, i.e. the the sources you want to compile depend on a version of a certain library that isn't yet in the repository of your distro. In some cases there is no way around compiling some other stuff first before compiling your initial sources.
If you still have troubles with compiling, ask the mailing list.
If the maintainer is not answering an no one else is able to help, try
to contact the maintainer.
- If this still doesn't help, the software might not be worth being used
at all.

Dear list,
There are many step by step sites to add repositories, externals, libraries and do other configuration. But what usually drops me down is that magic word "make".
Where could be the important points to understand and finish every "make" process my self?
Why lot's of "make" files are bad for my computer but, perhaps works fine for others?
Do I necessarily need to learn C++ to prepare pd work properly and have all libraries for my needs and "make, make, make" ?
What is wrong this time? (see terminal output) Thanks for help and time you take for it.
