They might be linked with other topics discussed recently about cctools, but it still seems somewhat different. </div><div class=""><br class=""></div><div class="">This happens with the port OpenBLAS, where the compilation fails when flags to compile AVX instructions yield errors during compilation, as described in the following tickets: </div><div class=""><a href="https://trac.macports.org/ticket/57912" class="">https://trac.macports.org/ticket/57912</a></div><div class=""><a href="https://github.com/xianyi/OpenBLAS/issues/1951" class="">https://github.com/xianyi/OpenBLAS/issues/1951</a></div><div class=""><br class=""></div><div class="">However, when I tried even more basic flags such as -march=native, compilation also fails with errors such as </div><div class=""><div style="margin: 0px; font-stretch: normal; font-size: 10px; line-height: normal; font-family: Monaco; color: rgb(242, 242, 242); background-color: rgba(0, 0, 0, 0.85098);" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">/var/folders/x8/q7j02h4d661_p7cjh42_jh380000gn/T//ccqkNy6A.s:103:no such instruction: `vxorps %xmm0, %xmm0,%xmm0'</span></div></div><div class=""><span style="font-variant-ligatures: no-common-ligatures" class=""><br class=""></span></div><div class=""><span style="font-variant-ligatures: no-common-ligatures" class="">I then tried with another gfortran compiler outside of macports, and it could compile without any issue if I remove macports’ prefix from the path, which seems to indicate that the issue is coming from the assembler in macports.</span></div><div class=""><span style="font-variant-ligatures: no-common-ligatures" class=""><br class=""></span></div><div class=""><span style="font-variant-ligatures: no-common-ligatures" class="">My best guess is that as in cctools is too old, but I am not sure about that.
