Package: dpkg-cross Version: 2.5.8 Severity: normal The current dpkg-cross conversion of pkg-config files is failing to catch some instances of /usr/include in the CFLAGS section of the .pc file. This isn't often a problem but when libraries rely on assembly code (like Qt), the presence of /usr/include in the command line passed to the cross-compiler preprocessor can cause i386 assembly to be included into the file to be armel cross compiler:
arm-linux-gnueabi-g++ -c -pipe -g -DQT_SHARED -I/usr/include/qt4
-I/usr/arm-linux-gnueabi/include/qt4/QtCore
-Wall -W -D_REENTRANT -fPIC -DQT_DBUS_LIB -DQT_CORE_LIB -I../armel
-I. -I/usr/arm-linux-gnueabi/include/qt4/QtCore
-I/usr/arm-linux-gnueabi/include/qt4/QtDBus
-I/usr/arm-linux-gnueabi/include/qt4 -I.
-I/usr/arm-linux-gnueabi/include -o confdata.o confdata.cpp
{standard input}: Assembler messages:
{standard input}:167: Error: bad instruction `lock'
{standard input}:168: Error: bad instruction `incl [r3,#0]'
{standard input}:169: Error: bad instruction `setne [fp,#-5]'
{standard input}:217: Error: bad instruction `lock'
{standard input}:218: Error: bad instruction `decl [r3,#0]'
{standard input}:219: Error: bad instruction `setne [fp,#-5]'
This happens because neither the QJson.pc nor the QtCore.pc files are converted
correctly.
The fix needs to handle both the includedir and the Cflags values.
Fixed version of the QJson.pc:
prefix=/usr/arm-linux-gnueabi
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

#
# you can set the following variables here:
# crossprefix: prefix for cross compiling binaries; default:
$(DEB_HOST_GNU_SYSTEM)-
# crossbase : base prefix for the following; default: /usr
# crossdir : base directory for architecture; default:
# $(CROSSBASE)/$(DEB_HOST_GNU_TYPE)
# crossbin : dir for binaries; default: $(CROSSDIR)/bin

# maintainer : maintainer name to pass to original dpkg-buildpackage
# in -m option. If not set at all, don't pass a -m, thus
# dpkg-buildpackage will use the name from the changelog
# file. If set to the special string CURRENTUSER,
# dpkg-buildpackage will use the name from the
# changelog, too, but signing the .changes will be done
# as the current user (default key).
# removedeps : comma-separated list of package names that should be removed
# from depends/conflicts/etc fields
# keepdeps : comma-separated list of package names that should be kept
# in depends/conflicts/etc fields as is, without adding
# -arch-cross.
#
# In preparation for merging dpkg-cross into dpkg, the previous
# defaults have been removed.
