I am quite new to using this system but managed to get it to make a
distribution of a shared library. The first try was, however, simple and
straight forward.
However, I want selectively add two files to the library based upon the
condition that they are *not* present on the target computer. In
configure.ac I added the lines:
AC_CHECK_FUNCS([strcasecmp strncasecmp],[CASECMP=1],[CASECMP=0])
AM_CONDITIONAL([NOCASECMP],[test CASECMP = 0])
Admittedly, I am completely guessing what is appropriate for the 2nd and 3rd
arguments of AC_CHECK_FUNCS because I cannot find any examples in the manual.
But I think I am a little closer on the AM_CON.. line---philosophically.
In Makefile.am I added the lines:
if NOCASECMP
libproject_la_sources += strcasecmp.c strncasecmp.c
The Makefile.am (and libtool) previously ran successfully without the new
lines. Note that I am only considering one condition even though there are
two files---if one is missing the other is also *very* likely to be missing.
I then ran autoreconf and ended up with:
autoreconf
src/Makefile.am:16: unterminated conditionals: NOCASECMP_TRUE
/usr/share/automake-1.9/am/ltlib.am: automake does not support am__installdirs
being defined conditionally
src/Makefile.am:3: while processing `lib_LTLIBRARIES'

automake: comment:

automake: owner: Automake
automake: }
automake: }
... plus some more.
I have RTFM'ed to exhaustion and would *greatly* appreciate a little guidance.
Thank-you in advance.
This system is the most arcane and obscure collection of sortware I have
encountered since I started programming in 1959.
