Re: Missing .h file?

[Peter Teeson]

 Of corse you are correct. Firstly specific thanks to Jürgen for his extra explanation.

Sorry for the interruption and thanks for all your kindness in replying.

Sadly it seems that I had the answer in my brain but these days it takes longer to access it. 

 I had sent the email  but then a few minutes later I realized it was a system header.

respect

Hi Peter,

the problem seems to be this:

The GNU APL build system is based on autoconf/automake which is the
standard for GNU projects and many others.

In this build system the src directory contains all possible source files.
The build system also supports a number of different build targets; the
most common being the GNU APL interpreter binaries, other less frequently
used ones are libapl, the GNU APL python language interface, the  GNU APL
erlang language interface, and so on.

The ./configure script allows the user to choose that target that should be
built and does this by selecting only a subset of all source files in the src
directory. In particular if you build the interpreter then the file
src/python_apl.cc is NOT one of the source files selected and the
missing Python.h is not needed (and a lack of it causes no harm).

Now, the Apple build system seems to work differently by trying to pick
all source files in the src directory as opoosed to only those needed for
the desired target. This is wrong, but ./configure cannot do anything
about it.

The easy fix for this is to simply remove the .cc files that complain before
initializing the Apple build system. Note that there are also files that are not
needed about which the build will not complain. The do not harm but make
the build target bigger than needed (keyword: dead code).

Of course every 'svn up' will restore the files so it may make sense to write
a small script that removes the files.

Best Regards,
Jürgen

In Terminal:

cd GNUapl 

svn co http://svn.savannah.gnu.org/svn/apl/trunk > svn-log 2>&1

Then was trying to see about building it as an Xcode command line project.

Added trunk folder to project, including sub-folders.

Did Build and got this message from the preprocessing.

Lexical or Preprocessor Issue

….GNUapl/trunk/src/python_apl.cc:3:10: 'Python.h' file not found

Did a multi-file search of trunk and sub-folders and did not find it.

Please check if the .h file is missing from svn checkout http://svn.savannah.gnu.org/svn/apl/trunk

Thanks

Peter
