libtool is eating my "-static" flag

[ericpruitt]

The version of libtool fails to properly compile the binaries because when passing "-static" in CFLAGS and LDFLAGS, it never reaches the compiler and linker toolchain. This results in a dynamically linked binary instead of a statically linked one. You can execute the following script to reproduce the issue which I have observed in both the latest release 10.42 and the current Git HEAD:

Editing to add a note: I copied the flags from an old PCRE 8 build. If I remove the obsolete options, CFLAGS, LDFLAGS and rely only on "--enable-static", I still get a dynamically linked executable as explained in this comment.

#!/bin/sh
set -x -e -u -f
test -e pcre2 || git clone https://github.com/PCRE2Project/pcre2.git
prefix="$PWD/prefix"
mkdir -p "$prefix"
cd pcre2
./autogen.sh
./configure -C \
    CC="c99" \
    CFLAGS="-static" \
    LDFLAGS="-static" \
    --disable-cpp \
    --disable-shared \
    --enable-jit \
    --enable-static \
    --enable-unicode-properties \
    --enable-utf \
    --prefix="$prefix" \
;
make install
ldd "$prefix/bin/pcre2grep"

Interestingly, I can successfully use --static instead of -static, a work-around I found on Stack Overflow. I noticed the issue while trying to build PCRE2 with musl, but I can also reproduce the issue using glibc.

This is what the output produces on my Debian 12 amd64 system:

pcre2$ ./x.sh

Libraries have been installed in:

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

Notice that ldd(1) shows it's dynamically linked when it should be statically linked. When using glibc, the binary still runs since I have glibc installed globally as the default libc on my system, but for musl, it produces a completely broken binary since the executable references a loader path that doesn't exist:

I see your call to ./configure had some issues:
configure: WARNING: unrecognized options: --disable-cpp, --enable-unicode-properties, --enable-utf

The way to generate static libraries is ./configure --enable-static --disable-shared I am not aware that you can do it via CFLAGS.

[ericpruitt]

I recently upgraded my build chain from PCRE 8.45 to PCRE2 and didn't look into the flags changing. That said, modifying them doesn't make a difference. I changed the invocation of configure to the following:

./configure -C \
    --disable-shared \
    --enable-jit \
    --enable-static \
    --prefix="$prefix" \
;

The exact same thing happens:

   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

more information, such as the ld(1) and ld.so(8) manual pages.

[PhilipHazel]

No idea, sorry. I don't know much about libtool and the build system. Maybe somebody else can help out...

[ericpruitt]

I narrowed down the problem in the generated libtool script down to this section:

      -static | -static-libtool-libs)
▷   # The effects of -static are defined in a previous loop.
▷   # We used to do the same as -all-static on platforms that
▷   # didn't have a PIC flag, but the assumption that the effects
▷   # would be equivalent was wrong.  It would break on at least
▷   # Digital Unix and AIX.
▷   continue
▷   ;;

If I delete the continue statement which is responsible for eliding the option, I get a correctly linked binary, so I'm applying the following patch locally to modify ltmain.sh:

Preserve "-static" flag in libtool to ensure generated binaries are statically
linked. See also: <https://github.com/PCRE2Project/pcre2/issues/341>.

I'm not proposing that this patch also be applied to the PCRE2 project since I'm not sure if this is a libtool bug, an issue with how it's being used or something else.

[PhilipHazel]

I have just tested running "./configure --disable-shared --enable-static" on HEAD and when I then ran make I ended up with these 4 files in .libs: libpcre2-8.a libpcre2-8.lai libpcre2-posix.a libpcre2-posix.lai. That is, I got static libraries. My libtool (running on Arch Linux) is 2.4.7.4-1ec8f-dirty (dunno what that means - it's what Arch update installed).

[ericpruitt]

I'm not having problems with the libraries. I'm having problems with the executables hence the ldd command:

+ ldd /home/ericpruitt/projects/pcre2/prefix/bin/pcre2grep
        linux-vdso.so.1 (0x00007ffe206c4000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f00f1d6c000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f00f2008000)

[PhilipHazel]

I understand now that it's the binaries you have a problem with, but unfortunately I am at a loss to know what to do. When I do a static build I get:

$ ldd ./pcre2test
linux-vdso.so.1 (0x00007ffff659a000)
libreadline.so.8 => /usr/lib/libreadline.so.8 (0x00007fc5dfd72000)
libc.so.6 => /usr/lib/libc.so.6 (0x00007fc5dfb90000)
libncursesw.so.6 => /usr/lib/libncursesw.so.6 (0x00007fc5dfb19000)
/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007fc5dffb7000)

This suggests to me that it is linking with a statically built PCRE2 library, but the dynamic links are for other libraries, some of which exist only in shared versions on my system. I'm afraid the autotools stuff is mostly magic to me (others created it).

[PhilipHazel]

Some quick experiments. I have discovered that LDFLAGS=--static ./configure --disable-shared ends up with non-dynamic executables for pcre2grep and pcre2test. I guess this is what you want. I'll add something to the documentation at some point and point out the differences between static PCRE2 libraries and static binaries.

[PhilipHazel]

Not sure why the quoted message below hasn't shown up in #341. Anyway, I've just added a comment there about this. Regards, Philip

Yes, because you used "--static" instead of "-static" which bypasses the questionable libtool logic. I mentioned this as a work-around in my first message:

Interestingly, I can successfully use --static instead of -static, a work-around I found on Stack Overflow. I noticed the issue while trying to build PCRE2 with musl, but I can also reproduce the issue using glibc.

If you use "-static", you still get a dynamically linked executable. I don't think users should be expected to know about the kludge of using "--static" instead of "-static" to get a properly linked executable.

[PhilipHazel]

Yes, I discovered that and am planning to make these points in a documentation update.
