我在 OS X 10.15.7 上使用 clang++ 构建 Octave 时遇到链接器错误。
例如“bsxfun_add(intNDArray<octave_int > const&, intNDArray<octave_int > const&)”，引用自：libcorefcn.a(libcorefcn_la-bsxfun.o) 中的 octave_value bsxfun_forward_op<intNDArray<octave_int >, &(bsxfun_add(intNDArray<octave_int > const&, intNDArray<octave_int > const&))>(octave_value const&, octave_value const&)

根据“nm -n”，函数（一旦被分解http://demangler.com) 位于静态库“libcorefcn.a”中。链接器错误似乎与通过参数 -force-load 包含的静态库有关。知道哪里出了问题吗？
答案1
我必须将 -std=c+11 切换为 -std=c++17 并添加 -isysroot
export CXXFLAGS="-std=c++11 -stdlib=libc++ -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk $CXXFLAGS"
这是配置命令：
./configure --with-libiconv-prefix=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/ CXXFLAGS="-std=c++17 -stdlib=libc++ -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk -I/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include -I/Users/davidlaxer/SuiteSparse/include -I/opt/local/include -I/opt/local/libexec/qt5/include -I/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/include" CPPFLAGS="-I/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include -I/Users/davidlaxer/SuiteSparse/include -I/opt/local/include -I/opt/local/libexec/qt5/include -I/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/include" LDFLAGS="-L/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/lib -L/Users/davidlaxer/SuiteSparse/lib/ -L/opt/local/lib -L/opt/local/libexec/qt5/lib -L/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/lib" DYLD_LIBRARY_PATH="-L/opt/local/lib -L/opt/local/libexec/qt5/lib -L/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/lib" LD_LIBRARY_PATH="-L/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/lib -L/Users/davidlaxer/SuiteSparse/lib/ -L/opt/local/lib -L/opt/local/libexec/qt5/lib -L/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home/lib" --with-suitesparseconfig-includedir=/Users/davidlaxer/SuiteSparse/include --with-suitesparseconfig-libdir=/Users/davidlaxer/SuiteSparse/lib --disable-readline --with-sundials_ida-includedir=/opt/local/include/sundials --with-sundials_ida-libdir=/opt/local/lib/ --with-qt=5
