Summary: base configure script does not detect nonfragile ABI correctly Project: GNUstep Submitted by: leeg Submitted on: Tue 13 Mar 2018 09:34:29 PM UTC Category: Base/Foundation Severity: 3 - Normal Item Group: Bug Status: None Privacy: Public Assigned to: None Open/Closed: Open Discussion Lock: Any _______________________________________________________ Details: Platform: linux (fedora core 27) Compiler: clang 5.0.1 ObjC runtime: libobjc2 GNUstep-make was configured with '--enable-objc-nonfragile-abi'. I see in the gnustep-config output: $ gnustep-config --objc-flags -MMD -MP -DGNUSTEP -DGNUSTEP_BASE_LIBRARY=1 -DGNU_GUI_LIBRARY=1 -DGNU_RUNTIME=1 -DGNUSTEP_BASE_LIBRARY=1 -fno-strict-aliasing -fexceptions -fobjc-exceptions -D_NATIVE_OBJC_EXCEPTIONS -fobjc-nonfragile-abi -D_NONFRAGILE_ABI -pthread -fPIC -g -DDEBUG -fno-omit-frame-pointer -Wall -DGSWARN -DGSDIAGNOSE -Wno-import -fobjc-runtime=gnustep-1.8.1 -fblocks -fobjc-runtime=gnustep-1.8.1 -fgnu-runtime -fconstant-string-class=NSConstantString -I. -I/home/leeg/GNUstep/Library/Headers -I/usr/local/include GNUstep-base configure script, when configured either with no flags or with --disable-mixedabi, does not detect the nonfragile abi. Then building -base fails, because I requested the nonfragile ABI but it can't find it. I find that if I compile the test program: $ clang config/config.non-fragile-ivars.m $ ./a.out $ echo $? 1 [i.e. no nonfragile ABI detected] however: $ clang -fobjc-runtime=gnustep-1.8.1 config/config.non-fragile-ivars.m $ ./a.out $ echo $? 0 [i.e. it was detected!] If I edit GSConfig.h by hand to change GS_NONFRAGILE=1, then -base builds and 'make check' succeeds. The expected behaviour is that ./configure correctly detects the nonfragile ABI availability. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?53338> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Bug-gnustep mailing list Bug-gnustep@gnu.org https://lists.gnu.org/mailman/listinfo/bug-gnustep
