Description Ivan Efremov 2009-03-10 15:57:09 UTC

Description of problem:

linux-g++/qmake.conf contains the following line:

QMAKE_CFLAGS_RELEASE	+= -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2  -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables

The question is: Why does CFLAGS_RELEASE variable contains '-g' debugging flag? Right after '-O2'? There shouldnt be any debuginfo when building in release mode.

Version-Release number of selected component (if applicable): 4.4.3

Comment 1 Rex Dieter 2009-03-10 17:55:16 UTC

These are the default compiler flags by which all of fedora is compiled with.

Comment 2 Rex Dieter 2009-03-10 17:59:15 UTC

well, I'll discuss it with my fellow qt/kde maintainers, maybe we could consider kicking out -g (but that would likely have ill side-effects building other qt-related packages in fedora... which we may or may not be willing to deal with).

Comment 3 Kevin Kofler 2009-03-10 19:04:39 UTC

We build our release binaries with debugging information in Fedora and then have RPM split it into separate files which land in separate -debuginfo packages.

Comment 4 Ivan Efremov 2009-03-11 06:41:28 UTC

OK, I understand, but it really looks like a some kind of hack, because other major linux distributions (AFAIK, including fedora 9) don't use such _global_ assignments.

Comment 5 Ivan Efremov 2009-03-11 06:45:53 UTC

In fact it really affects applications which have qmake-based build system. It looks very strange when you build application (and create binary packages) in a _standard_ way on number of linuxes, and resulting _release_ binaries on fedora 10 are ten times bigger than others because of debug information.

Comment 6 Than Ngo 2009-03-12 14:09:10 UTC

It's the default compiler flag in fedora what is needed to get the debug infos. The user still can strip the binary with install -s that is supported in Makefiles by install, if they don't want the debug information.

Comment 7 Ivan Efremov 2009-03-12 14:21:23 UTC

Yes sure, but installation instructions in makefiles are also generated by qmake. And when I use everything by default it doesn't include strip to Makefile. It's specific problem only of fedora 10.

Comment 8 Kevin Kofler 2009-03-12 15:10:36 UTC

We also configure qmake not to strip by default for the same reason we have it use -g by default.
