Hi,

I have created a library package (libpsc) using "src-autoconf-lib" , it builds the template fine , but if use .cpp file it fails.
I have tried several changes to configure.ac and ( ran ./configure each time). It fails at the C++ directive
#include <string>

I have include the configure.ac and some relevant searches below
Any suggestions much appreciated.

Thanks Pat

# Rule of thumb: when your library needs an external library, add it

#
# Don't add libraries without a check. Even if you know the 'sqrt()' requires
# 'libm' on most systems, check for its real need with 'AC_SEARCH_LIBS(sqrt, m)'.
# Doing it in this way will ensure an embedded developer knows exactly what
# dependencies your library has (because it gets listed in the *.pc file).
#
# Another way for checking libraries is the PKG_CHECK_MODULES macro. But please
# honor if a user switches off a feature you also switch of the test for a
# external component via PKG_CHECK_MODULES when it is no longer required!
# PKG_CHECK_MODULES returns *_CFLAGS and *_LIBS. Again, add the *_LIBS to the
# global 'LIBS', but for the CFLAGS you can decide if you add them to the
# CFLAGS, AM_CFLAGS or as substitution variables in the Makefile.am.

Hi,

I tried renamed libpsc.c to libpsc.cpp ( and .ccx) , no difference in the outcome,  running ./configure fails and so does the ptxdist libpsc compile.

Question , in a autotools library package are you only allowed either c file or c++ file ?

Hi,

Yes I did already change AC_CONFIG_SRCDIR in configure.ac , I have tried renaming the libpsc.c to libpsc.cxx and libpsc.cc ,
Still make no difference .

It seems the "default" is it expects a file called libpsc.c .

----------------------
target: libpsc.prepare
----------------------

configure: error: cannot find sources (libpsc.c) in ../libpsc or ..
make: *** [/opt/lib/ptxdist-2019.03.1/rules/post/ptxd_make_world_prepare.make:22: /opt/PHYTEC_BSPs/BSP-Phytec-phyFLEX-i.MX6-PD13.2.4/platform-phyFLEX-i.MX6/state/libpsc.prepare] Error 1

I still believe it hasn't found the C++ compiler .
