cross-compiling

问题 I am bit confused with the terms of cross platform and cross compiler. Let me be first clear about the cross platform. When people talk about cross platform it means the architecture of the CPU, i.e, X86 and X64 ? or the OS i.e windows 32 bit or Windows 64 (server or desktop)? UNIX doesn't have different flavours like 64 bit or 32 bit. Why so? .NET and java is cross compiler language, what it means? When the program is compiled in .NET, we have to choose the option like X86, X64 or Any CPU.

问题 I've been working on a c++ project for a while now, but would like to port it over to my arm processor. I already have all of my cross-compile tools (I'm using CodeSourcery) and thought I could just change my makefile to point to that compiler. It compiles fine using the default g++, but When try a make pointing to the cross-compiler I get relocation errors: /home/oryan/CodeSourcery/bin/../lib/gcc/arm-none-linux-gnueabi/4.5.2/../../../../arm-none-linux-gnueabi/bin/ld: ServerSocket.o:

问题 I am trying to compile a C++/Fortran program using conda on an Ubuntu 18.04 server where I do not have superuser rights. I am able to compile correctly the program with the same source code on my Ubuntu 18.04 PC (using conda too), but on the server I get a bunch of errors. At the moment, I am stuck with a "library not found - undefined reference" error: gfortran -o glm -Wl,--export-dynamic obj/glm_globals.o obj/glm_util.o obj/glm_csv.o obj/glm_mobl.o obj/glm_mixu.o obj/glm_wqual.o obj/glm

问题 Hi I would like to know if using SBT is possible to cross compiling against different Scala version using different sources for some classes. To keep back compatibility basically but leverage also on the new language features. Thanks. 回答1: You can add additional source directories based on scala version by adding to the unmanagedSourceDirectories setting. Something like this: unmanagedSourceDirectories in Compile <+= (scalaVersion, sourceDirectory in Compile) { case (v, dir) if v startsWith

问题 Cmake is ad I'm trying to cross compile for raspberry pi 3+ on a Mac using cmake to generate a makefile. My CMakeLists.txt: cmake_minimum_required (VERSION 3.11.0) project(decatrack) # setup cross toolchain for RPi 3 set(CMAKE_SYSTEM_NAME Linux) set(CMAKE_SYSTEM_PROCESSOR arm) set(TOOLCHAIN_DIR /Volumes/xtool-build-env/armv8-rpi3-linux-gnueabihf) set(CMAKE_C_COMPILER ${TOOLCHAIN_DIR}/bin/armv8-rpi3-linux-gnueabihf-gcc) set(CMAKE_CXX_COMPILER ${TOOLCHAIN_DIR}/bin/armv8-rpi3-linux-gnueabihf-g++

问题 I want to build an ARM application(just a simple main function) on Windows host using GCC Linaro toolchains version 7.4.1. Compilation is OK, my .o files are created but on linking step I get the following errors(tested on different computers and result is same) Errors start from locale.o file... But that /home/tcwg-builds/.. directory is not related to my computer paths... Building target: arm_cpp Invoking: Cross G++ Linker arm-eabi-g++ -o "arm_cpp" ./src/arm_cpp.o c:/users/yunus/desktop

问题 I am trying to build an application(libnodeapplication) which is dependent on a shared library(libnode.so) which in turn depends on another shared library(libgentoo-5.so.100) which I have pasted at the same location as the libnode(inside /usr/lib/) Problem is second dependent library is symbolically linked to another file what changes are needed in the compile command to build it successfully(for symbolically linkd files refrened in the shared library) I tried with -Wl,-rpath=<path to usr/lib

问题 I'm having serious trouble getting cinttypes to work properly on mingw64-w64 when cross-compiling. I've gotten it down to a minimal(ish) example that runs in docker. inttypes_test.cpp #include <cstdio> #include <cstddef> #include <cstdint> #include <cinttypes> #include <cstdarg> __attribute__((format(printf, 1, 2))) static void myPrintf(const char* fmt, ...) { va_list args; va_start(args, fmt); vprintf(fmt, args); va_end(args); } int main(int argc, const char** argv) { int i32 = 5; int64_t
