compilation

问题 I am trying to cross-compile the GNU Scientific Library (gsl, v1.16) for ARM architecture (specifically the Raspberry Pi). I have used the following to configure; CROSS=armv6j-hardfloat-linux-gnueabi ./configure --host=x86_64-pc-linux-gnu --build=$CROSS --target=$CROSS \ CC=/usr/bin/$CROSS-gcc \ CXX=/usr/bin/$CROSS-g++ \ AR=/usr/bin/$CROSS-ar \ RANLIB=/usr/bin/$CROSS-ranlib \ CFLAGS="-march=armv6 -mfloat-abi=hard -mfpu-vfp" I get the following error messages: libtool: compile: /usr/bin/armv6j

问题 In our projects it happens (rarely but it happens) that in a derived class a non-virtual method from the base-class is hidden by a method with the same prototype. In that case the compiler (in our case g++ 4.4) stays quiet. While I can see that no warning can be useful for private methods, for protected or public methods this should be at least a configurable warning. If such a things exists I'm unable to find it. Here's a small example I'd like to have g++ complain about (be assured that

问题 I have a problem with my report. It now come to try to make some changes, but it turns out I can not compile the report even without having changed anything.

问题 I'm learning Ocaml language but i have a problem with my modules when i want to compile them. So, I have a module with the name Door and an other one with the name Case. Into each one, i have a type paramater with the other module : Door.mli type t = bool -> Case.u -> t Case.mli type u = bool -> Door.t -> u When i want to compile, i have this error : File "door.mli", line 14, characters 23-29: Error: Unbound module Case Have you got an idea ? Thanks you 回答1: You have two mutually recursive

问题 I want to build both a static and shared version of the same library as described here. However, the sources are compiled twice, one for each version which is not necessary. Any ways of avoiding this ? 回答1: Depends on the platform. On Linux at least, you need to use different compiler flags to produce position-independent (shared library) than ordinary (program or static library) code. 来源： https://stackoverflow.com/questions/8912938/how-to-build-a-shared-and-a-static-library-without

问题 I have a problem with having Netbeans compile the way I want to. I can't get Netbeans to compile my program. When I'm in the Ubuntu Terminal I can compile my program with the following command: gcc -L/usr/local/lib -I/usr/local/include/libxml++-2.6 -I/usr/local/lib/libxml++-2.6/include -I/usr/include/libxml2 -I/usr/include/glibmm-2.4 -I/usr/lib/i386-linux-gnu/glibmm-2.4/include -I/usr/include/sigc++-2.0 -I/usr/lib/i386-linux-gnu/sigc++-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/i386-linux

问题 I am trying to build QT libraries statically and with /MT (runtime static linking). I have followed the next steps: 1. Go to qmake.conf file and modify /MD to /MT in both release and debug configurations 2. I run configure command like this: configure -static -opensource 3. I run nmake The problem is that nmake fails a few seconds after running. Here are the last output: [..........] qjson.cpp qjsondocument.cpp qjsonobject.cpp qjsonarray.cpp qjsonvalue.cpp qjsonparser.cpp qjsonwriter.cpp

问题 Another of my queries about an embedded Python 2.7.3 interpreter on Windows. I need to install numpy and matplotlib as support packages for an embedded interpreter in a C++ program compiled in Visual Studio 2010. Some background: I've been trying to make this work for a few months. The main issue is that numpy for Python 2.7 is compiled against an earlier version of the MS C library (VS2008) whereas my application is compiled against the 2010 version (a fact beyond my control - that is the

问题 I'm having an issue that's taking me since yesterday morning to figure it out with no success. I'm really desperate right now to solve this.
