Relative or independent paths in libtool .la file

阅读更多关于 Relative or independent paths in libtool .la file

My .la file has full pathnames in both the dependency_libs= section and the libdir= section which makes it difficult to copy my libraries to a different machine (same arch but different path structure). What is the solution to this, besides having some script to hack the .la file to adjust for the paths on the new machine? ==Details== When I ./configure; make; make install my libfoo , depending on how I use the --prefix , --exec-prefix , and DESTDIR= flags, I'll get an entry in the libfoo.la file that reads libdir=/dir1/lib and I'll have the actual .so files in the same dir as libfoo.la .

Compiling Erlang code on Windows

阅读更多关于 Compiling Erlang code on Windows

I installed Erlang 13B and tried to follow the tutorials. Every time I get to c(tut) , I get an error instead of (ok, tut) , so it seems like there are no modules installed. Can anyone point me in the right direction? I've tried Emacs but I don't really know how to use it and haven't even got close to getting the Erlang mode working. For instance, where do I type: (setq load-path (cons "C:/Program Files/erl5.6.2/lib/tools-<ToolsVer>/emacs" load-path)) (setq erlang-root-dir "C:/Program Files/erl5.6.2") (setq exec-path (cons "C:/Program Files/erl5.6.2/bin" exec-path)) (require 'erlang-start) For

阅读更多关于 how to compile opencl project with kernels

问题 I am totally a beginner on opencl, I searched around the internet and found some "helloworld" demos for opencl project. Usually in such sort of minimal project, there is a *.cl file contains some sort of opencl kernels and a *.c file contains the main function. Then the question is how do I compile this kind of project use a command line. I know I should use some sort of -lOpenCL flag on linux and -framework OpenCL on mac. But I have no idea to link the *.cl kernel to my main source file.

Empty function macros

阅读更多关于 Empty function macros

问题 If I define a function macro with no actual body, is it like an empty string with the compiler (i.e. It doesn't generate any extra instructions at compile time)? Example: #define SomeMacro(a) SomeMacro("hello"); // This line doesn't add any instructions, does it? 回答1: You're absolutely correct, the empty macro doesn't generate any code. I've seen two places where this is useful. The first is to eliminate warnings when a function parameter isn't used: #define UNUSED(x) int foo(int UNUSED(value

Making GCC and Other C++ Compilers Very Strict

阅读更多关于 Making GCC and Other C++ Compilers Very Strict

问题 I'm working on a large collaborative C++ project that is both developed and run on various flavors of Linux, OS X and Windows. We compile across these platforms with GCC, Visual Studio C++ and the Intel C++ compiler. As more and more people start developing code for the project, we're starting to see weird errors in compilation and runtime that are specific to particular compilers on particular operating systems. An example of this is implicit inclusion of headers that certain OS/compiler
