Attachment: Final link line

Similar error as reported https://bugzilla.mozilla.org/show_bug.cgi?id=334866#c11

Filing new bug as requested by bsmedberg in the final comment in that bug.

I'm building XULRunner on 64Bit FC5 with gcc 4.1.1-1 with the following mozconfig options:

ac_add_options --enable-debug
ac_add_options --disable-optimize
ac_add_options --disable-javaxpcom
ac_add_options --enable-svg
ac_add_options --enable-canvas
ac_cv_visibility_pragma=no

Everything is great until linking libxul:

/usr/bin/ld: ../../dist/lib/components/libgklayout.a(nsCanvasRenderingContext2D.o): relocation R_X86_64_PC32 against `_moz_cairo_new_path' can not be used when making a shared object; recompile with -fPIC

Attachment: Diagnosis log

bsmdeberg and I went over this today and concluded that this was probably a gcc bug. Attached is our conversation.

FYI: This also applies to FC6 (x86_64) with gcc 4.1.1-51

[BASTIEN David]

I have got exactly the same error on Kubuntu 6.10 (64 bits version) with gcc-4.1.1-13 when I try to compile xulrunner (CVS tag : MOZILLA_1_8_BRANCH) . But I have got a little different message when I try to compile it with gcc-3.4.6-3 : 

/usr/bin/ld:
../../staticlib/components/libgklayout.a(nsCanvasRenderingContext2D.o):
relocation R_X86_64_PC32 against `_moz_cairo_pattern_destroy' can not be used when making a shared object; recompile with -fPIC

Dupe of bug 378303 ?

We saw this long before the dbus stuff landed, so I doubt it. We'll try again sometime soon.

Comment 6

[Tomas A. Haavet]

I've tried compiling against the latest version from the trunk, containing the path from bug 378303, with the same result as before.

Comment 7

[John Gaunt (redfive)]

We just tried a build and this problem has gone away for us.

I built on FC5 64bit with the following flags, note we are no longer using the visiblity pragma=no option. I forget what changed to cause us to no longer need that but we've had it commented out for some time.
