If I compile this QT c++ program in SuSE Linux #include <iostream> using namespace std; int main () { cout << "Hello World!"; return 0; } When I type i386-mingw32-g++ helloworld.cpp I get the following error i386-mingw32-g++: error trying to exec 'cc1plus': execvp: No such file or directory Is this because MinGW ...
Hi, I'm setting up a C++ project, on Ubuntu x64, using Eclipse-CDT. I'm basically doing a hello world and linking to a commerical 3rd party library. I've included the header files, linked to their libraries, but I still get linker errors. Are there some possible problems here other than the obvious (e.g. I am 99% sure I'm linking to ...
I am writing a program that is cross platform. There are a few spots where I have to specify an operating system dependent call. #ifdef WINDOWS ..do windows only stuff #endif #ifdef LINUX ..do linux only stuff #endif Are there any preprocesser directives that get defined by the compiler so I don't have to explicitly define them w...
When compiling : #include <vector> template<class T> class foo { void bar() { std::vector<T> x; std::vector<T>::iterator i = x.begin(); } }; int main() { return 0; } I get : # g++ ~test.cpp test.cpp: In member function `void foo<T>::bar()': test.cpp:7: error: expected `;' before "i" Shouldn't this w...
Trying to use the RHEL5.3 GCC 4.3.2 compiler to build my software on that platform. I get the following error no matter what I try when compiling with -O2, but it builds fine without optimization. Any ideas? /usr/bin/ld: myapp: hidden symbol `void std::__ostream_fill<char, std::char_traits<char> >(std::basic_ostream<char, std::char_tr...
I'm trying to learn the details behind how the compiler works and I was wondering what the symbol B means when using nm. I tried to follow std::cout into libstdc++, but it ends with nm -DC /usr/lib/libstdc++.so.6 | grep cout 000e8da0 B std::cout 000e9020 B std::wcout Where is the link to the actual function and what does the B mean? ...
Hello, all! I am writing a program in C++ which uses the CLAPACK ATLAS library. However, I cannot get the program to link successfully to the library. I have written a small C program to better demonstrate the problem. Interestingly enough, this small demonstration program links just fine if I compile it with GCC, but I get the same link...
Is it possible to use a library compiled by visual studio in an application compiled by g++ (mingw) on Windows? ...
Hi Guys, Ok so I have an app that I'm writing that uses a library that someone at work developed. I've included the xcode project in my project and included the output target of that project in my project's target as a framework. I also included the .a file in my target under the "Link Binrary with Libraries" folder. I also have put in ...
Hello all, I'm quiet familiar with gcc assembly... Recently I was forced to turn back to g++ for some codes clean up. Let me mention I'm too much familiar with assembly, hence, for some curiosity purposes, I often get a look at how good the compiler generated asm is. But the naming conventions with g++ are just bizaare. I was wondering...
Hello, I'm have an application built with the -std=gnu++0x parameter in tdm-mingw g++ 4.4.0 on windows. It is using an ofstream object and when I build, it gives the following linking error: c:\opt\Noddler/main_func.cpp:43: undefined reference to `std::basic_ofstream<char, std::char_traits<char> >::basic_ofstream(std::string const&, st...
I'm learning C++ and when I was testing the Microsoft Visual C++ 2008 Express and Eclipse Ganymede, but with the g++ compiler as default, I've noted that a same code in VC++ get some errors and in g++ compile normally, without errors or warnings and execute normally, but I want to know what is the difference between VC++ syntax and g++ s...
Hi, I am very aware of compiling C++ programs with g++ in linux environment. But, may be I am missing something, I am getting this strange output/behaviour. I have source file in test.cpp. To compile this, I did (1) g++ -c test.cpp g++ -o test test.o ./test Everything works fine. But when I did compling and linking in same stage, ...
This seems like it should be really simple. I compiled a library in Qt (this newmat library), and produced the file libnewmat.a. Now I need to integrate this library into another project but I just can't get it to work. I've tried a few different things with the LIBS variable in my .pro file including: Win32:LIBS += libnewmat.a #libr...
I have a C function that contains all the code that will implement the bytecodes of a bytecode interpreter. I'm wondering if there is a way to align segments of the compiled code in memory on fixed size boundaries so that I could directly calculate the address to jump to from the value of the bytecode? Sort of the same way an array work...
Hello! I would like to know if I can use g++ to compile C++ source files stored on an FTP server? Can this be done? Thanks NOTE: The FTP server is within the local network ...
I'm trying out the solution to a question about specialized template classes. This code with a compiles fine in g++, but throws up linker errors when compiled with gcc. What's the cause of these errors ? $ g++ traits2.cpp $ gcc traits2.cpp /tmp/ccI7CNCY.o: In function `__static_initialization_and_destruction_0(int, int)': traits2.cpp...
In C++, I know that the compiler can choose to initialize static objects in any order that it chooses (subject to a few constraints), and that in general you cannot choose or determine the static initialization order. However, once a program has been compiled, the compiler has to have made a decision about what order to initialize these...
