![]() C++ Standards supported by Clang, GCC, and Xcode: MacPorts have two alternates to provide C and C++ compilers: Clang and GCC.Ī project can require a more recent C standard or C++ standard than is provided by the Xcode compiler.Ĭ Standards supported by Clang, GCC, and Xcode: This ideal, however, cannot always be achieved. Ideally, Xcode would provide the C and C++ compilers. If MacPorts provides the compiler, the appropriate dependencies are added.The environment variables CC and CXX are set during the configure phase if use_configure is yes (the default). ![]() , configure.cxx, and configure.cpp are set.This means that, unless instructed otherwise, each Portfile will have access to a compiler for both of these languages. C and C++ are fully supported in the base. These commands do nothing more than set environment variables during the configure phase if use_configure is yes. However, some language have direct support in the MacPorts base. The port lapack-manpages builds documentation by calling doxygen.Ĭommonality among several ports can be gathered into a portgroup.įor example, there is a portgroup that facilitates building projects written in Rust. The lowest level of support is for a Portfile to call the appropriate build command. The flexibility of a Portfile allows MacPorts to support a wide variety of languages. Ifort finstrument-functions g save-temps O2 sample.f90 bridges.The following most-commonly used Portfile commands will choose a set of appropriate compilers with the required capability for a given OS version:įor further details and more related options, please read on. I do not know if someone with additional experience using the Mac OS X performance tools can make further progress using the bridge routines with the Intel Fortran compiler or not. ![]() The IA-32 GNU C++ compiler operates fine when linking with the Saturn library, and the report displays routine names. It is unclear what the issue is here and more investigation is required into using Saturn with the Intel compilers that I will take up with compiler development. The major issue that exists with the report when using the Intel Fortran compiler is that Saturn is unable to display any Fortran routine names despite all my efforts to ensure the presence of symbols. I could launch the execution under Saturn and raise the resulting output report. Using the bridge routines allowed me to compile/link using the IA-32 Intel Fortran 10.1 and 11.0 compilers. Ld64 warning: in /usr/lib/libSaturn.dylib, missing required architecture x86_64 in file I was somewhat successful using the bridge routines below on Mac OS X 10.5.2 with Xcode 3.0 and the IA-32 Intel Fortran 10.1.015 and 11.0.034 Beta compilers.įirst, I could not link the Saturn library using either the Intel or GNU Intel 64 compilers due to the following: Assuming the GCC Mac OS decorations are correct, we will likely decorate accordingly per the specific requirement on each OS. Regardless, GCC on Mac OS is clearly compatible with the Saturn library decorations. While our name decoration is compatible with GCC on Linux, GCC on Mac OS is clearly different although the man page does not indicate this. This mismatch was reported to our Compiler development team. On Mac OS X, a third leading underscore is expected. The unresolved externals received when linking the Saturn library and using the Intel Fortran compiler involve a difference between the name decorations for the instrumented routines. It is unclear what that issue is, but that may be of little importance given the above information. On Leopard (10.5.5) with Xcode 3.1.1, I cannot produce a gmon.out file using Intel or GNU compilers. Apparently this is a know issue that is not related to the Intel compilers and I reproduced this using both Intel compilers and GNU C++ (gcc 4.0.1) on Leopard (10.5.2) w/Xcode 3.0. ![]() I confirmed information I found that gprof has always produced zero timings on what others refer to as an "Intel Mac". This is not an area I'm familiar with, but after some investigation here is what little I can offer. ![]()
