I have the same version of gcc 4.6.1 ($ gcc --version gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1) and I've compiled wine-1.4-rc5 with and without additional flags.
The version compiled without flags doesn't work with Steam in-game overlay, but the second one works. I've used those flags: CFLAGS="-O3 -pipe -fno-strict-aliasing -fomit-frame-pointer -ffunction- sections -fdata-sections -maccumulate-outgoing-args -mno-push-args -freorder-blocks-and-partition" LDFLAGS="-s" This means that the gcc bug is still present, because the old gcc 4.5 ($ gcc-4.5 --version gcc-4.5 (Ubuntu/Linaro 4.5.3-9ubuntu1) 4.5.4) doesn't need any extra flags for working overlay. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/900901 Title: Steam overlay does not work due to GCC-4.6 issues To manage notifications about this bug go to: https://bugs.launchpad.net/wine/+bug/900901/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
