[developers] compiling fftb

[goodman.m.w at gmail.com]

Hi all,

I'm getting similar errors to Alexandre. I successfully compiled and
installed liba, repp-0.2.2, and then ace, but I'm getting the error that it
cannot find <tsdb.h> I try "make all" for libtsdb. I noticed that tsdb.h is
provided by libtsdb, and `#include <tsdb.h>` seems to look in my system
libraries. Changing all these to `#include "tsdb.h"` (thinking it might use
the file in the current directory) did not work, so I reverted those
changes and ran the following:

    make libtsdb.a  # required for 'make install'
    make libtsdb.so  # required for 'make install'
    make install  # copies the above 2 things plus tsdb.h to /usr/local/lib/

Then I tried running "make all" again and now I see this:

    [...]
    test.c: In function ‘main’:
    test.c:599:2: warning: implicit declaration of function
‘ace_load_grammar’ [-Wimplicit-function-declaration]
      599 |
 ace_load_grammar("/home/sweaglesw/cdev/ace-regression/comparison.dat");
          |  ^~~~~~~~~~~~~~~~

    /usr/bin/ld: /usr/lib/x86_64-linux-gnu/libm-2.31.a(e_log.o): in

    collect2: error: ld returned 1 exit status
    make: *** [Makefile:45: test.static] Error 1

It seems there's some incompatibility in glibc versions. This SO question
seems relevant: https://stackoverflow.com/q/56415996/1441112 ; maybe it's a
static vs. dynamic linking issue? Other than test.static, I was able to
make other targets, such as art and mkprof, but I see errors when I try to
run them:

    $ ./art -h
    ./art: error while loading shared libraries: libace.so: cannot open
shared object file: No such file or directory

But I have libace.so at /usr/local/lib/libace.so, so I'm not sure what went
wrong here. My end goal is to compile FFTB, and if I carry on with the
current setup I see the same errors as when compiling test.static when I do
"make fftb" for the FFTB source code. Does anybody know how to get around
these issues?

Some context:
* For compiling ACE I copied itsdb_libraries.tgz as described here:
http://moin.delph-in.net/AceInstall#Missing_itsdb.h
* I'm running Pop!_OS 20.04 (similar to Ubuntu), with glibc version 2.31
