Hello,
I am trying to get my first open source project distribution set up to
build with autotools (incl. libtool). It is a fairly simple C++ wrapper
library around the Gnu "argp" options parser program. I would like to
configure the build so as to produce a shared library which is installed
in "/usr/local/lib" and the header "argpp.hpp" in "/usr/local/include".
Problem: I would like to name my library "libargp++" but not having much
success. Not sure if the problem lies more with automake than with
libtool, but I suspect it could be libtool. When I use the name
"libargpp", everything works. All I have to do is run "autoreconf -i"
from the project directory, then "./configure", "make" and "sudo make
install". Of course, I know that it can work by writing the Makefile by
hand, but I want to use autotools, and the "++" in the name seems to
cause trouble.
The project directory structure looks like this ... for now, I am
leaving out README, ChangeLog, etc. until I can get the "bare bones" to
work:
(project root:)
---/include: argpp.hpp argppbaseimpl.hpp
---/src: argpp.cpp argppbaseimpl.cpp Makefile.am
---/m4: (empty)
configure.ac
Makefile.am
Makefile.am in the root directory looks like this:
ACLOCAL_AMFLAGS = -I m4
SUBDIRS = src
(not much can go wrong there). Here is the Makefile.am in the src
subdirectory:
lib_LTLIBRARIES = libargpp.la
libargpp_la_SOURCES = argpp.cpp argppbaseimpl.cpp argppbaseimpl.hpp
libargpp_la_CXXFLAGS = $(CXXFLAGS) -I$(top_srcdir)/include
libargpp_la_LDFLAGS = -version-info 1:0:0
libargpp_includedir = $(includedir)
include_HEADERS = $(top_srcdir)/include/argpp.hpp
I tried this instead:
lib_LTLIBRARIES = libargp++.la
libargp++_la_SOURCES = argpp.cpp argppbaseimpl.cpp argppbaseimpl.hpp
libargp++_la_CXXFLAGS = $(CXXFLAGS) -I$(top_srcdir)/include
<etc.>
and got several errors at "make" time.
Here is configure.ac (I took the check for std::unique_ptr<T> from
another project; it works quite well):

AC_INIT([Argpp], [1.0.0], [my_em...@fakeaddr.com], [libargpp],

Is there a way?
Thanks!
