Re: libtool not generating / installing .so, even tho config says it should

[Scott Robert Ladd]

Thank you ever so much. In past editions, the compiles included the default
CFLAGS followed by the ones I specified.

I don't know if this had ever worked, but the culprit seems to be this 
part of your configure.ac:


if test "x$gccopt" = "xyes"
then
CFLAGS="-std=gnu99 -pedantic -Wall -Wno-format -lpthread -lrt -O2 
-g0 -march=native"

else
CFLAGS="-std=gnu99 -pedantic -Wall -Wno-format -lpthread -lrt -g 
-O2 -static"

fi


Besides this, this part overrides CFLAGS with hard-coded compiler- and 
system-specific CFLAGS - Not a good idea.

libtool not generating / installing .so, even tho config says it should

[ScottLadd]

I've been writing configure.ac scripts for a long time, and now,
unexpectedly, on a new Kubuntu 11.04 installation and on a Fedora 15
install, libtool not longer generates and installs shared objects. Same
scripts I've used before, different behavior.


Note: The configure.ac/Makefile.am in question DID install shared objects in
the past.


When I run configure, it states:


checking whether the gcc linker (/usr/bin/ld -m elf_x86_64) supports shared
libraries... yes
checking whether -lc should be explicitly linked in... no
checking dynamic linker characteristics... GNU/Linux ld.so
checking how to hardcode library paths into programs... immediate
checking whether stripping libraries is possible... yes
checking if libtool supports shared libraries... yes
checking whether to build shared libraries... yes
checking whether to build static libraries... yes


Upon running make install, I see:


test -z "/usr/local/lib" || /bin/mkdir -p "/usr/local/lib"
 /bin/bash ../libtool   --mode=install /usr/bin/install -c   libbrahe.la
'/usr/local/lib'
libtool: install: /usr/bin/install -c .libs/libbrahe.lai
/usr/local/lib/libbrahe.la
libtool: install: /usr/bin/install -c .libs/libbrahe.a
/usr/local/lib/libbrahe.a
libtool: install: chmod 644 /usr/local/lib/libbrahe.a
libtool: install: ranlib /usr/local/lib/libbrahe.a


I've hunted up and down, to no avail, trying to figure out what's wrong. Did
something change in a recent update to autotools? My versions are:


libtool 2.2.6b
automake 1.11.1
autoconf 2.67
