Dear all
I am not sure if this is to be adressed to libtool or maybe automake
since the problem might come from depcom...
Anyway I am trying to build a c++ library using libtool on a
alphaev6-dec-osf5.0
using cxx.
These set up should allow to archive correctly
# The archiver.
AR="ar"
AR_FLAGS="-rv"
RANLIB="ar ts"
old_archive_cmds="\$AR \$AR_FLAGS \$oldlib
\${libname}_la/*.o\$oldobjs\$old_deplibs~\$RANLIB\$oldlib"
If a directory of templates are created in ./\${libname}_la for example.
Now when using dependency tracking the mode choosen is
checking dependency style of cxx... conftest.o: conftest.c
conftest.o: conftest.h
dashmstdout
When running
% make libutilities_la-parser.lo
source='parser.cpp' object='libutilities_la-parser.lo' libtool=yes \
depfile='.deps/libutilities_la-parser.Plo'
tmpdepfile='.deps/libutilities_la-parser.TPlo' \
depmode=dashmstdout /bin/ksh ../depcomp \
/bin/ksh ../libtool --mode=compile cxx
-DPACKAGE=\"mudfas\" -DVERSION=\"0.9\" -DHAVE_LIBM=1 -DSTDC_HEADERS=1
-I. -I. -I. -DHDF -I/astro/local/opt/HDF_4.1r3/4.1r3_digunix/include
-I/mn/sothi/u1/patrickg/src/blitz -DFLOAT_FIELD -ptr libutilities_la
-nocompress -std strict_ansi -DBZ_DISABLE_XOPEN_SOURCE -ieee -c -o
libutilities_la-parser.lo `test -f parser.cpp || echo './'`parser.cpp
cxx -DPACKAGE=\"mudfas\" -DVERSION=\"0.9\" -DHAVE_LIBM=1 -DSTDC_HEADERS=1
-I. -I. -I. -DHDF -I/astro/local/opt/HDF_4.1r3/4.1r3_digunix/include
-I/mn/sothi/u1/patrickg/src/blitz -DFLOAT_FIELD -ptr libutilities_la
-nocompress -std strict_ansi -DBZ_DISABLE_XOPEN_SOURCE -ieee -c parser.cpp
-o libutilities_la-parser.o
echo timestamp > libutilities_la-parser.lo
Surprise, there is no libutilities_la-parser.o!
I have put a set -x in top of libtool and in order to find dependencies
the compiler is ran with the option -M
The problem is that when specifying -M with cxx even though you put also
the options -c -o $obj you don't create the .o file.
And it looks like that the .o is removed first and then the cxx -M is run
without running again cxx alone, therefore the .o is not created.
Sincerely
Patrick
