Hi Folks Recent macOS / xcode update broke the version of clang in conda so I can no longer build (SCons decides that the compilers don’t support C++11) I can build just fine, and everything works and all the tests pass However if I try and recompile anything SCons swears at me and dies as it decides that the perfectly valid C++11 compilers I have don’t compile C++11 because … some reason which makes no sense to me. Here is content of config.log Grey-Area build :( $ cat config.log file /Users/graeme/git/dials/modules/cctbx_project/libtbx/SConscript,line 865: Configure(confdir = .sconf_temp) scons: Configure: ".sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0.cpp" is up to date. scons: Configure: The original builder output was: |.sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0.cpp <- | |#include <iostream> | |int main() { | | std::cout << "{"; | | #ifndef __llvm__ | | #define __llvm__ "" | | #endif | | std::cout << "\"llvm\":" << __llvm__ << ", "; | | #ifndef __clang__ | | #define __clang__ "" | | #endif | | std::cout << "\"clang\":" << __clang__ << ", "; | | #ifndef __clang_major__ | | #define __clang_major__ "" | | #endif | | std::cout << "\"clang_major\":" << __clang_major__ << ", "; | | #ifndef __clang_minor__ | | #define __clang_minor__ "" | | #endif | | std::cout << "\"clang_minor\":" << __clang_minor__ << ", "; | | #ifndef __clang_patchlevel__ | | #define __clang_patchlevel__ "" | | #endif | | std::cout << "\"clang_patchlevel\":" << __clang_patchlevel__ << ", "; | | #ifndef __GNUC__ | | #define __GNUC__ "" | | #endif | | std::cout << "\"GNUC\":" << __GNUC__ << ", "; | | #ifndef __GNUC_MINOR__ | | #define __GNUC_MINOR__ "" | | #endif | | std::cout << "\"GNUC_MINOR\":" << __GNUC_MINOR__ << ", "; | | #ifndef __GNUC_PATCHLEVEL__ | | #define __GNUC_PATCHLEVEL__ "" | | #endif | | std::cout << "\"GNUC_PATCHLEVEL\":" << __GNUC_PATCHLEVEL__ << ", "; | | #ifndef __clang_version__ | | #define __clang_version__ "" | | #endif | | std::cout << "\"clang_version\": \"" << __clang_version__ << "\", "; | | #ifndef __VERSION__ | | #define __VERSION__ "" | | #endif | | std::cout << "\"VERSION\": \"" << __VERSION__ << "\", "; | | std::cout << "}"; | | return 0; | |} | scons: Configure: ".sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0.o" is up to date. scons: Configure: The original builder output was: |/usr/bin/c++ -o .sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0.o -c .sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0.cpp | scons: Configure: ".sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0_79477a053ab4616bb93a6d1a8e51fb1f" is up to date. scons: Configure: The original builder output was: |/usr/bin/c++ -o .sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0_79477a053ab4616bb93a6d1a8e51fb1f .sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0.o | scons: Configure: ".sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0_79477a053ab4616bb93a6d1a8e51fb1f.out" is up to date. scons: Configure: The original builder output was: |.sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0_79477a053ab4616bb93a6d1a8e51fb1f > .sconf_temp/conftest_171626668f451c9275a8effd06a8fea3_0_79477a053ab4616bb93a6d1a8e51fb1f.out | file /Users/graeme/git/dials/modules/cctbx_project/libtbx/SConscript,line 1143: Configure(confdir = .sconf_temp) scons: Configure: ".sconf_temp/conftest_e73942b1e04111dec1918a18e43ee693_0.cpp" is up to date. scons: Configure: The original builder output was: |.sconf_temp/conftest_e73942b1e04111dec1918a18e43ee693_0.cpp <- | |#include <iostream> | |#include <vector> | |#include <array> | |#include <utility> | |std::vector<int> func(std::vector<int> && in) {std::vector<int> r = std::move(in); return r;} | |int main() {std::vector<int> x(9); for(auto & i : x) {i=7; std::cout << i << std::endl;} | | x = func(std::vector<int>(2)); return 0;} | | | scons: Configure: ".sconf_temp/conftest_e73942b1e04111dec1918a18e43ee693_0.o" is up to date. scons: Configure: The original builder output was: |/usr/bin/c++ -o .sconf_temp/conftest_e73942b1e04111dec1918a18e43ee693_0.o -c -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.9 -I/Users/graeme/git/dials/conda_base/include -I/Users/graeme/git/dials/modules -I/Users/graeme/git/dials/modules/cctbx_project -Iannlib_adaptbx/include -I/Users/graeme/git/dials/modules/annlib_adaptbx/include -I/Users/graeme/git/dials/modules/cctbx_project/annlib_adaptbx/include .sconf_temp/conftest_e73942b1e04111dec1918a18e43ee693_0.cpp | /usr/bin/c++ -o .sconf_temp/conftest_e73942b1e04111dec1918a18e43ee693_0_3b63d4473a8f41665bd62af890bf3763 -w -stdlib=libc++ -mmacosx-version-min=10.9 -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.9 .sconf_temp/conftest_e73942b1e04111dec1918a18e43ee693_0.o -L/Users/graeme/git/dials/conda_base/lib -Llib -L/Users/graeme/git/dials/modules/lib -L/Users/graeme/git/dials/modules/cctbx_project/lib clang: error: no such file or directory: '.sconf_temp/conftest_e73942b1e04111dec1918a18e43ee693_0.o' clang: error: no input files Key point is this: I can blow away the build directory and it all compiles correctly, but if I touch a file and type make I get build failures as so Has anyone a clue about this? Should I add an issue on GitHub? Thanks Graeme -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.
