Bug 420641 – app-text/ghostscript-gpl-9.05-r1 - libgs.so gets built with _start etc

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Brian Modra 2012-06-11 07:49:39 UTC]

When the libgs.so gets created, the -shared parameter is not passed, and so it
gets built with _start etc.

If I edit soobj/ldt.tr, and add the -shared parameter, and then all is happy

The problem is that the configure is called and passed -Wl,--as-needed

  Title                     --as-needed enabled in default profiles
  Author                    Tomáš Chvátal <[e-mail]>
  Posted                    2010-08-01
  Revision                  1

-Wl,--as-needed has been added to the default profile's LDFLAGS.

This option optimizes the linking process, only linking binaries to
libraries that are truly needed. This way, fewer libraries are loaded
at runtime and fewer packages need to be rebuilt after library updates.

To take advantage of the new default you can either rebuild world now
or just allow the system to migrate incrementally as it updates.

Please note that setting LDFLAGS="<your flags>" in your make.conf will
override the profile defaults. If you want to add additional LDFLAGS
it is recommended to use LDFLAGS="${LDFLAGS} <your flags>" instead to
avoid this.

For more information on --as-needed, read [1].

[1] http://www.gentoo.org/proj/en/qa/asneeded.xml

This needs to be overridden for ghostscript-gpl

I tried adding "append-ldflags $(no-as-needed)" to the emake, (and I hacked the Manifest so it was happy)

pkg_setup() {
        if use bindist && use djvu; then
                ewarn "You have bindist in your USE, djvu support will NOT be compiled!"
                ewarn "See http://djvu.sourceforge.net/gsdjvu/COPYING for details on licensing issues."
        fi
        append-ldflags $(no-as-needed)
}

... but then it does this:

./soobj/aux/echogs -w ./soobj/ldt.tr -n - x86_64-pc-linux-gnu-gcc -Wl,-O1 -Wl,--as-needed -Wl,--no-as-needed   -o ./sobin/libgs.so.9.05
./soobj/aux/echogs -a ./soobj/ldt.tr -n -s ./soobj/gsromfs0.o ./soobj/gs.o -s


If I set LDFLAGS in /etc/make.conf, then ghostscript compiles OK.

[Comment 1 Brian Modra 2012-06-11 08:04:26 UTC]

A correction, setting LDFLAGS in /etc/make.conf did not work
It still sets up ldr.tr incorrectly - with -as-needed and without -shared

[Comment 2 Rafał Mużyło 2012-06-11 10:00:10 UTC]

'-Wl,--as-needed' is by no means a problem.
./soobj/aux/echogs -w ./soobj/ldt.tr -n - i686-pc-linux-gnu-gcc -Wl,-O1 -Wl,--
as-needed -Wl,--sort-common -Wl,-z,relro   -shared -Wl,-soname=libgs.so.9 -o .
/sobin/libgs.so.9.05
...
i686-pc-linux-gnu-gcc -Wl,-O1 -Wl,--as-needed -Wl,--sort-common -Wl,-z,relro   -shared -Wl,-soname=libgs.so.9 -shared -o ./soobj/X11.so ./soobj/gdevxalt.o ./soobj/gdevx.o ./soobj/gdevxcmp.o ./soobj/gdevxini.o ./soobj/gdevxres.o ./soobj/gsparamx.o -L/usr/X11R6/lib -lXt -lSM -lICE -lXext -lX11

Try searching for the problem where it actually is.
Start with attaching your 'emerge --info' and posting 'emerge -1pv app-text/ghostscript-gpl'.

...on the other hand, attach full build log from *before* you've started tinkering with the ebuild.
