[Bug 18832] New: compiling with -fprofile-generate fails on sfnt2fnt due to hidden symbol
http://bugs.winehq.org/show_bug.cgi?id=18832 Summary: compiling with -fprofile-generate fails on sfnt2fnt due to hidden symbol Product: Wine Version: 1.1.23 Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: tools AssignedTo: wine-bugs(a)winehq.org ReportedBy: scott(a)open-vote.org I've been attempting to experiment with compiling Wine using profile guided optimization, however make fails in tools/sfnt2fnt due to a hidden symbol.

http://bugs.winehq.org/show_bug.cgi?id=18832 --- Comment #2 from Scott Ritchie <scott(a)open-vote.org> 2009-06-07 21:51:03 --- If I add -fprofile-generate to LDFLAGS (as well as CFLAGS) then the hidden symbol errors go away (a similar thing happens when I manually add -shared to the cflags of the makefiles for these parts). The gcov errors remain, however.

http://bugs.winehq.org/show_bug.cgi?id=18832 --- Comment #3 from Scott Ritchie <scott(a)open-vote.org> 2009-06-08 05:48:18 --- No -fno-profile-generate is needed for the (4 or 5) programs like sfnt2fnt if you build this way: make distclean && CFLAGS="-Wall -g -O2 -fprofile-generate" LDFLAGS="-fprofile-generate -lgcov" ./configure --host=x86_64-linux-gnu --build=x86_64-linux-gnu && make However this again leads to a gcov error, this time in libwinecrt0 make[2]: Entering directory `/home/scott/src/wine-1.1.23-oldprofiled/dlls/avifile.dll16' ../../tools/winegcc/winegcc -m32 -B../../tools/winebuild --sysroot=../.. -shared ./avifile.dll16.spec -Wb,--subsystem,win16,--main-module,avifil32.dll -o avifile.dll16.so -lavifil32 -lkernel32 ../../libs/port/libwine_port.a -fprofile-generate -lgcov ../../dlls/winecrt0/libwinecrt0.a(dll_entry.o): In function `__wine_spec_dll_entry': /home/scott/src/wine-1.1.23-oldprofiled/dlls/winecrt0/dll_entry.c:30: undefined reference to `__gcov_indirect_call_profiler' I will note that some dlls seem to build and link fine. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

http://bugs.winehq.org/show_bug.cgi?id=18832 --- Comment #5 from Scott Ritchie <scott(a)open-vote.org> 2009-06-08 20:46:16 --- If I profile selectively, I can get subsets of the Wine source to build with -fprofile-generate. Here's an issue I found from googling for gcov symbol errors: http://stackoverflow.com/questions/566472/where-is-the-gcov-symbols --- I just spent an incredible amount of time debugging a very similar error. Here's what I learned: * You have to pass -fprofile-arcs -ftest-coverage when compiling. * You have to pass -fprofile-arcs when linking. * You can still get weird linker errors when linking. They'll look like this: libname.a(objfile.o):(.ctors+0x0): undefined reference to `global constructors keyed to long_name_of_file_and_function' This means that gconv's having problem with one of your compiler-generated constructors (in my case, a copy-constructor). Check the function mentioned in the error message, see what kinds of objects it copy-constructs, and see if any of those classes doesn't have a copy constructor. Add one, and the error will go away. Edit: Whether or not you optimize can also affect this. Try turing on / switching off optimizations if you're having problems with it. --- These are the same kinds of errors I'm getting (/home/scott/src/wine-1.1.23-profiled/dlls/winecrt0/dll_entry.c:30: undefined reference to `__gcov_indirect_call_profiler') So perhaps the suggestion is relevant to winecrt0. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
