toolchain

问题 I provide a Yocto SDK to cross-build an application for an embedded target. The application itself is built using CMake. The SDK setup script provides many necessary environment variables (like location of the cross-compiler, sysroot, etc.), which so far was enough to build the application. However, since recently the application has a dependency to the Boost library (through the command find_package(Boost REQUIRED) in the CMakeLists.txt). Now CMake complains that it cannot find the library,

问题 While building ARM toolchain , I got the following error checking for suffix of object files... configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[1]: *** [configure-target-libgcc] Error 1 make[1]: Leaving directory `<path>/gcc-4.3.2-arm-elf' make: *** [all] Error 2 what might be the problem? 回答1: Did you read http://gcc.gnu.org/wiki/FAQ#configure_suffix ? Have you installed GMP, MPFR and MPC? Are they in your library search path?

问题 After upgrading to Catalina from Mojave, Setuping: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk in the env. I'm unable to compile a program that use <cmath> header. I tried changing CFLAGS, CCFLAGS, CXXFLAGS to point to the MacOSSDK Location that change nothing Scanning dependencies of target OgreMain /Applications/Xcode.app/Contents/Developer/usr/bin/make -f OgreMain/CMakeFiles/OgreMain.dir/build.make OgreMain/CMakeFiles/OgreMain.dir

问题 Similar to this situation [*]. Follow up clarification please, as I'm in a parallel universe: A. Me , as single Apple Developer. and B. Client , with team of two - I was just added as person 2, an Admin (NOT the Agent - he's person 1). Client gives me source code for an * App rewrite/fix. * First version is still live on App store, my upgrade is to be its replacement. I did the App rewrite on my machine, using my Apple dev account and my developer certs for device testing. So, at this point,

问题 I'm trying to use AppWeb, and i wrote a very simple program to embed AppWeb into my application, it's using a function in AppWeb library. #include <appweb/appweb.h> int main(int argc, char** argv) { return maRunWebServer("appweb.conf"); } I dont know when I compile with gcc (or cc), it compiled successful. But, when I cross compile to Arm architecture, is have been getting error. This is my Makefile: CC = gcc LIBS = lib FLAG = -lappweb -lmpr TEST_TARGET = embed-appweb OBJS = embed-appweb all:

问题 If I have created a bluemix toolchain through UI, how can I export that. I see there's an option to create a toolchain from a template described in yml files. But how can I get these yml files for an existing toolchain created using UI. Thanks 回答1: In it's current form and shape, there isn't a import-export option for the toolchains. The existing toolchain templates have a repository where the file representation is stored (YAML, JSON and others). Clone a toolchain from this github repository

问题 I am using 32Bit Ubuntu 14.04, where newest version of libc6 is already installed. When I run 'poky-qemu qemuppc zImage-2.6.37-qemuppc-1.0.bin yocto-image-lsb-sdk-qemuppc-1.0.rootfs.ext3' , I am getting following error: /opt/poky/1.0/sysroots/i686-pokysdk-linux/usr/bin/qemu-system-ppc: /opt/poky/1.0/sysroots/i686-pokysdk-linux/lib/libc.so.6: version `GLIBC_2.17' not found (required by /usr/lib/i386-linux-gnu/libdrm.so.2) Is this problem in toolchain or my host machine? How to solve this error

问题 I have used interpolated strings (ie $"Hello my name is {name}" ) for a while and I use this much more heavily than ordinary strings. Is there a way to tell the compiler that to always assume that a string is interpolated so I don't have to type the dollar sign? Using event variable, a #pragma, something in .sln, or a nuget package? 来源： https://stackoverflow.com/questions/44166762/automatic-interpolated-strings
