Bug Description

Hi,

when recompiling calibre to fix #826835, I'm getting the following error, and even if I think this may be linked to --as-needed flag, I'm not able to fix it. The relevant part of the compilation log is:
...
g++ -m64 -Wl,-O1 -shared -Wl,-soname,libprogress_indicator.so.1 -o libprogress_indicator.so.1.0.0 QProgressIndicator.o moc_QProgressIndicator.o -L/usr/lib/x86_64-linux-gnu -lQtGui -lQtCore -lpthread
...
Setting up bash completion...

Any help is welcome. Thanks,

Fabrice

That error is saying that the linker cannot find the symbol _ZTI7QWidget. That
symbol is defined in libQtGui.so.4. Use the LD_DEBUG environment variable to
get information on why the linker is unable to find and load that symbol on
your system.

I'm getting the same build failure here. It seems to be caused by the sip4 package not being updated for http://wiki.debian.org/ToolChain/DSOLinking . Here's the relevant method in siputils.py:

 851 def platform_lib(self, clib, framework=0):
 852 """Return a library name in platform specific form.
 853
 854 clib is the library name in cannonical form.
 855 framework is set of the library is implemented as a MacOS framework.
 856 """
 857 ##################################################################
 858 # Generally, the linker is intelligent enough not to need this #
 859 # additional information! #
 860 # And Qt4's pkg-config and prl files are broken #
 861 # Changed for Debian packaging, Torsten Marek <email address hidden> #
 862 ##################################################################
 863
 864 return []
 865
 866 if self.generator in ("MSVC", "MSVC.NET", "MSBUILD", "BMAKE"):
 867 plib = clib + ".lib"
 868 elif sys.platform == "darwin" and framework:
 869 plib = "-framework " + clib
 870 else:
 871 plib = "-l" + clib
 872
 873 return plib

Commenting out line 864 includes -lQtGui -lQtCore when building progress_indicator.so and allows the build to complete successfully.

This bug was fixed in the package calibre - 0.8.8+dfsg-1ubuntu1

---------------
calibre (0.8.8+dfsg-1ubuntu1) oneiric; urgency=low

  * fix_ftbfs_as-needed.patch: add missing QtGui lib when linking
    progress_indicator with --as-needed. This fixes a FTBFS (LP: #828304) and
    allow calibre to run (LP: #826835). Thanks Jason Conti for the help!
