Need help buiding bfd shared library

[Potharla, Rupesh]

[Public]

Hi,

I am working on building bfd shared library for my code changes. I tried with "configure --enable-shared=bfd" but BFD is creating static library only even with -enable-shared option .  Did I miss something ? Can someone help me with the instructions to build bfd shared library?

Regards,
Rupesh P

Did you try --enable-shared without "=bfd"? So far I wasn't aware of
that form as an option, and at least a quick inspection of the
configure script also doesn't suggest that form might exist. But I
may be entirely wrong ...

I tried that option as well and tried with --enable-host-shared combination also but no luck.

You may want to inspect configure output then. Here in bfd/config.log I see

configure:8674: checking whether the gcc -std=gnu99 linker (/usr/lib/gcc/.../ld) supports shared libraries
configure:9745: result: yes
...
configure:11365: checking if libtool supports shared libraries
configure:11367: result: yes
configure:11370: checking whether to build shared libraries
configure:11391: result: yes
configure:11394: checking whether to build static libraries
configure:11398: result: yes

I would guess one of these is failing for you, at which point you'd want to
figure out why that is.

None of the above is failing for me. I looked at the config.log file and tried the combination of different options none of them is working. In fact, I don't see a target for libbfd.so in the Makefile.  

configure:11283: checking whether stripping libraries is possible
configure:11288: result: yes
configure:11323: checking if libtool supports shared libraries
configure:11325: result: yes
configure:11328: checking whether to build shared libraries
configure:11349: result: yes
configure:11352: checking whether to build static libraries
configure:11356: result: yes
configure:8563: checking for dlfcn.h
configure:8563: result: yes

Just out of curiosity is the --enable-shared option really working for others?  Am I missing something during the compilation?

Look for a libbfd.la target. There's libtool involved here, and I think
that's the rule where the .so linking happens (at the same time as
the creation of libbfd.a). IOW I suppose all depends on the flags
passed to libtool ...

Yes (on Linux; on Cygwin the answer would be "no").

"./configure --enable-shared=bfd --enable-host-shared && make " is the command I am running for this. I ran it on multiple Linux machines but did not see libbfd.so.  
Can you confirm the command ?

No, I cannot. As said previously, all I ever use is --enable-shared
(without any "=bfd").

AC_DISABLE_SHARED supports `--enable-shared=PKGS', but there are some
places that use `test "$enable_shared" = yes' instead of `test
"$enable_shared" != no'.

[Errol Millios]

The version I am currently using is a bit old, but I built a version
of 2.36.1 last night with these exact commands on Debian 11:

> cd binutils-build
> ../binutils-gdb/configure --target=<arch> --prefix=<install-dir> --disable-nls -v --enable-shared
> make -j16 & make install

and after building I have

> find -name "libbfd.so"
./binutils-build/bfd/.libs/libbfd.so
./install/x86_64-pc-linux-gnu/tarn-elf32/lib/libbfd.so

The first time it failed building for some reason, but after I rm
-Rf'd the build directory and rebuilt everything, it worked fine.
