compilation

问题 I'm compiling a database library with pro C which converts the .ppc library file to a .c file that gcc can use. However, I'm getting a lot of errors in pro C like the following PCC-S-02201, Encountered the symbol "__ attribute__ " when expecting one of the `following` ... , Encountered the symbol "__builtin_va_list" when expecting one of the `following` The missing symbols are from a chain of standard includes like stdio.h and stdlib.h. How do I get around this issue? The library I'm

问题 I successfully compiled v8 javascript engine (on windows) ; now I try to follow the Getting started article but I am stuck at this point: Compile hello_world.cpp, linking to the static libraries created in the build process. The example is for linux (and probably for an earlier version). I tried to link against all libraries that I could without success: User@PC:/cygdrive/c/Users/Yvain/Documents/depot_tools/v8/build/Release g++ -std=c++0x -I"C:\Users\Yvain\Documents\depot_tools\v8" -Llib -lv8

问题 I have a web project running in Visual Studio 2010 and target .Net framework 4. When I 'Build' the solution it will tell me the build was successful even though there are (known) errors in the code. If I open a page that has an error, the compiler will then pick up on the error and underline it in blue instead of red. Is there a setting that would drive this kind of behavior? Any ideas on how to fix? 回答1: If you have multiple projects in your solution it is possible that one of them is not

问题 I'm trying to build the libdwarf api under windows but I'm receiving the following compile errors. in dwarf_elf_access.c undefined type Elf32_Ehdr, undefined symbol EI_CLASS undefined symbol ELFCLASS64 undefined symbol ELFDATA2LSB ... I did a search through all the header files and source files and I couldn't find them defined anywhere as far as I could tell. Are these unix/linux specific definitions? If it is how should these errors be resolved under windows? Thanks 回答1: It seems you need to

问题 Could someone explain why the following c++ code is not behaving as expected: struct Object { template< int i > void foo(){ } }; template<int counter> struct Container { Object v[counter]; void test(){ // this works as expected Object a; a.foo<1>(); // This works as well: Object *b = new Object(); b->foo<1>(); // now try the same thing with the array: v[0] = Object(); // that's fine (just testing access to the array) # if defined BUG1 v[0].foo<1>(); // compilation fails # elif defined BUG2 (v

问题 I have installed NppExecute plugin in notepad++. I am not able to figure out next step to compile and debug C,C++ programs in Notepad++. System Details: (a) Turbo C directory C:\TC (b) OS Windows 7 Please provide complete details on how to set Environment Variable and Scripts for Compiling and Debugging. 回答1: Notepad++ has the run feature, but as far as I know it's unable to help you debugging (e.g. stepping through code, watching variables, etc.). Your best bet would be using a simple batch

问题 I just submitted an app update to the iOS AppStore with 64-bit and 32-bit compatibility. I haven't changed anything except the 64-bit architecture, however the app size is now almost doubled from a pre-64-bit size of 2.7 MB to 4.5 MB. Is this normal when compiling the app for both 64-bit and 32-bit iOS devices? Why does this happen (anyone care to explain in technical terms)? Or did something funky just happen in Xcode? 回答1: It's pretty normal because the code is compiled twice - once for 32

问题 Thanks to the guys that helped me with my previous question (linked just for reference). I can place the files fileTypeTest.cpp , libmagic.a , and magic in a directory, and I can compile with g++ -lmagic fileTypeTest.cpp fileTypeTest . Later, I'll be testing to see if it runs in Windows compiled with MinGW. I'm planning on using libmagic in a small GUI application, and I'd like to compile it statically for distribution. My problem is that libmagic seems to require the external file, magic .

问题 I need to build linphone for iOS (and android and windows after that, but that is of later concern). Since no one is able to answer my previous question nor a similar one, can someone at least point me to a good resource on the subject? I feel like I tried everything already, and the project still won't compile (lot's of files missing, include paths are wrong, libraries can't be found etc...). Linphone doesn't have a forum as far as I know, and any threads I find on the internet are

问题 Okay, so I have been searching for this problem for a while, and I still am clueless as to how to solve it. I am trying to run the sample code available here: http://docs.opencv.org/trunk/d1/dc5/tutorial_background_subtraction.html. I understand the code. I just cannot get it to compile! The problem is with library includes . Here's my Makefile : CFLAGS = `pkg-config --cflags opencv` LIBS = `pkg-config --libs opencv` % : %.cpp g++ $(CFLAGS) $(LIBS) -o $@ $< Here's the error : prakhar@inS4n3 ~
