Tracking this upstream, not sure myself whether it is a bug or not, ObjC is very badly specified language. gcc-4.6.0-0.9.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/gcc-4.6.0-0.9.fc15 Package gcc-4.6.0-0.11.fc15: * should fix your issue, * was pushed to the Fedora 15 updates-testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing gcc-4.6.0-0.11.fc15' as soon as you are able to, then reboot. Please go to the following url: https://admin.fedoraproject.org/updates/gcc-4.6.0-0.11.fc15 then log in and leave karma (feedback). gcc-4.6.0-0.11.fc15 has been pushed to the Fedora 15 stable repository. If problems still persist, please make note of it in this bug report. |
Description of problem: raidem is no longer rebuilding and stops with the following error: gcc -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables -W -Wall -Wno-deprecated-declarations -fno-strict-aliasing -Iinclude -Ilib -DNO_MP3 `/usr/bin/pkg-config AllegroOGG --cflags` -DNO_ALRAND -DNO_FBLEND -DGLYPH_TARGET=GLYPH_TARGET_ALLEGRO -DNO_ID3TAGS -DRAIDEM_DATA_DIR=\"/usr/share/raidem\" -o obj/candy/turret.o -c src/candy/turret.m src/candy/tank-track.m:73:1: error: instance variable has unknown size It looks like the code causing the problem is: @interface TankTrack: Candy { BITMAP *spr; int max_track_life; } @end (from raidem-0.3.1-src/include/candy/tank-track.h) BITMAP is defined in raidem-0.3.1-src/include/candy.h as: struct BITMAP; I don't really know objective C, so I might just be confused, but it looks as if pointers to empty structs is supposed to work. The way these values are used later, it doesn't look void will work. Probably there is a way to do it with unions, but that would be a hard change for me to make in the code. Version-Release number of selected component (if applicable): gcc-4.6.0-0.7.fc15.i686 How reproducible: Steps to Reproduce: 1. fedpkg clone raidem 2. cd raidem 3. fedpkg local Actual results: Expected results: Additional info:
