Please report it ASAP so that we don't get a LLVM release with this bug. >> andy [~]$ >> andy [~]$ llvm-config --link-static --libs bitwriter >> -lLLVMBitWriter -lLLVMAnalysis -lLLVMProfileData -lLLVMObject >> -lLLVMMCParser -lLLVMMC -lLLVMBitReader -lLLVMCore -lLLVMBinaryFormat >> -lLLVMSupport -lLLVMDemangle >> andy [~]$ >> andy [~]$ llvm-config --link-static --system-libs >> -lrt -ldl -lcurses -lpthread -lz -lm >> >> On a "good" (-DLLVM_LINK_LLVM_DYLIB=ON) I get > > > With both: > -DLLVM_BUILD_LLVM_DYLIB=ON and -DLLVM_LINK_LLVM_DYLIB=ON > Something's a bit strange: >> andy [~]$ llvm-config --link-shared --libs bitwriter >> -lLLVM-6.0svn >> andy [~]$ llvm-config --link-static --libs bitwriter >> -lLLVMBitWriter -lLLVMAnalysis -lLLVMProfileData -lLLVMObject >> -lLLVMMCParser -lLLVMMC -lLLVMBitReader -lLLVMCore -lLLVMBinaryFormat >> -lLLVMSupport -lLLVMDemangle >> andy [~]$ llvm-config --link-static --system-libs >> -lrt -ldl -lcurses -lpthread -lz -lm > > > I get mostly the same: > > Radeon/Mesa> llvm-config --link-shared --libs bitwriter > -lLLVM-6.0svn > Radeon/Mesa> llvm-config --link-static --libs bitwriter > -lLLVMBitWriter -lLLVMAnalysis -lLLVMProfileData -lLLVMObject -lLLVMMCParser > -lLLVMMC -lLLVMBitReader -lLLVMCore -lLLVMBinaryFormat -lLLVMSupport > -lLLVMDemangle > Radeon/Mesa> llvm-config --link-static --system-libs > -lrt -ldl -ltinfo -lpthread -lz -lm > ^^^^^^^^ > > Dieter _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
