smartmontools build fails on QNX

[Christian Franke]

The compilation on QNX fails due to missing getopt_long(). A proposed patch using the existing implementation in 'posix/getopt*' compiles, but leads to further problems related to exception handling.

r3083: getopt_long() from 'posix/getopt*' is now in a new directory 'getopt'.

[Christian Franke]

Proposed patch for configure.in and Makefile.am, requires r3083.

uncomments getopt in getopt.h in order to use getopt provided by QNX ibc

[stevestereo]

checked out SVN 3108 and applied the configure-getopt.patch.
was able to configure and so on but build fails with the following output:

Reason is that getopt() is also provided by QNX libs.
-> I uncommented line 147 in getopt.h to overcome this error, but I don't know
about compatibility. ( I added a patch with my change )

Another approach might be to not use the getopt sources from smartmontools but
use native getopt() and install libgetopt from pgksrc to get getopt_long instead.
What do you think?

Replying to stevestereo:

about compatibility. ( I added a patch with my change )

With the following Makefile.am change (rerun ./autogen.sh) it might work without changing getopt.h:

 if NEED_GETOPT_LONG
-AM_CPPFLAGS += -I$(srcdir)/getopt -DHAVE_GETOPT_LONG
+AM_CPPFLAGS += -I$(srcdir)/getopt -DHAVE_GETOPT_LONG -D__GNU_LIBRARY__
 endif

-D__GNU_LIBRARY__ worked in the original patch, see ticket #68.

smartmontools uses getopt_long() only, native getopt() is not needed. Using libgetopt should work without any changes to current SVN if libgetopt provides its own /LIBGETOPT_INCLUDE_DIR/getopt.h and smartmontools is configured with

./configure CPPFLAGS=-I/LIBGETOPT_INCLUDE_DIR

If this works we can add this setting to configure.in later.

Tried your proposal and it worked, here is what I did

# svn revert --recursive .        
# patch < configure-getopt.patch  
changed stated line in Makefile.am and added -D__GNU_LIBRARY__ manually
# ./autogen.sh                    
# ./configure CPPFLAGS=-I/LIBGETOPT_INCLUDE_DIR 
# make

getopt()does not conflict anymore

[stevestereo]

based on configure-getopt.patch but includes fix for getopt and missing cast in os_qnxnto.cpp

[stevestereo]

created a patch with all the changes for getopt() and a missing cast
​https://sourceforge.net/attachment/ticket/1/configure-getopt-qnx.patch
sequence which was working for me:

# svn revert --recursive .                      
Reverted 'configure.in'
Reverted 'os_qnxnto.cpp'
Reverted 'Makefile.am'
# patch < configure-getopt-qnx.patch 
patching file configure.in
patching file os_qnxnto.cpp
patching file Makefile.am
# ./autogen.sh
configure.in:33: installing `./config.guess'
configure.in:33: installing `./config.sub'
configure.in:23: installing `./install-sh'
configure.in:23: installing `./missing'
# ./configure
# make

Afterwards I was able to run smartctl -a /dev/hd0 within my virtualbox

# ./smartctl -a /dev/hd0
