No sources to compile?

[Henrik Jönsson]

Hi,

I'm trying to setup nar on a small static gcc lib. But I have problem with the compile step. Nar doesn't seem to find my C file.

I'm using the recommended directory structure:

src

  main

    c

      UASList.c

    include

      UASList.h

pom.xml

Can anyone of you spot any problems in my files?

Maven says:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: Defaulting to no-operation (NOP) logger implementation

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

The problem is there are no default includes because the aol.properties are
* too specific.
* don't contain  gcc.Windows.c  settings.

Some things you can do to investigate further and possible resolve.

Build using mvn -X option to get debug output and more detail on what it is searching for to find compilable files. (double check my analysis)

Possible resolutions in your config
1.  gpp instead of gcc (not familiar with variations myself)

2. This will find the files, not sure if the compiler will actually work though

<c>

<name>gcc</name>

<includes><include>**/*.c</include></includes>

</c>

3.  Use a custom aol.properties file for the project - make a file aol.properties in the project.basedir
GPP might be good as an example - https://github.com/maven-nar/nar-maven-plugin/blob/master/src/main/resources/com/github/maven_nar/aol.properties

[Henrik Jönsson]

Thanks for you quick answer!

It seems to work when I add:

<includes><include>**/*.c</include></includes>

I thought this was the standard behavior. But it seems like

x86.Windows.gpp.c.includes=**/*.c

exists, but not this:

x86.Windows.gcc.c.includes=**/*.c

in the built-in aol.properties file.

Is this because the primary purpose of nar is to run javah (with g++)?

Best regards

Henrik

[Greg Domjan]

Hi Henrik,

I would not put javah as the primary purpose, just one of various.

The reason behind the limitation is more that the configuration

* is incomplete based only what people have needed so far

* in being as flexible as possible has not also been made as a simple as possible and so each combination must be specfied seperately, and nobody has tried that combination yet.

As I most use msvc daily I'm not aware of the differences between using gpp and gcc, went looking and found http://stackoverflow.com/questions/172587/what-is-the-difference-between-g-and-gcc

With that I would call the linker GCC, the C compiler gcc, the CPP compiler gpp/g++.  

Have raised issue of how this should be configured on the github issues board

We welcome very much input from others, pull requests help a lot.
