I'm using gcc, which implements enums as 32 bit integers on the architecture I have (don't know in general). If I try to assign an enum value too large, I get warning: integer overflow in expression Is there a way to make gcc use 64 bit integers as the underlying integer type? A gcc specific way is fine, although if there's a portabl...
I'm trying to compile Redis for Windows x64 with no luck. I tried different things Cygwin works perfectly but GCC produces only 32 bit executables Compling with Mingw-w64 will not work without a lot of code changes (My understanding is that MinGw does not provide POSIX compatibility for Windows) Microsoft Services for Unix has an outd...

Dear all, I have a set of software library modules which are developed in c++. So, I use g++ to compile my software. This has to be used by various existing applications which are written in C and compiled with gcc. When the other teams used g++ to compile their code, they started getting lot of compiler errors due to strict type che...
Hello, i have the following code compiled with GCC 4.2 / XCode. template <typename T> class irrProcessBufferAllocator { public: T* allocate(size_t cnt) { return allocProcessBufferOfType<T>(cnt); } void deallocate(T* ptr) { if (ptr) { releaseProcessBuffer(ptr); } } ...
When "make check" for GCC4.5.0, such error was occured: make[1]: Entering directory `/home/username/tool/gcc-4.5.0' /bin/sh: line 0: cd: host-x86_64-unknown-linux-gnu/fixincludes: No such file or directory make[1]: *** [check-fixincludes] Error 1 make[1]: Leaving directory `/home/username/tool/gcc-4.5.0' make: *** [do-check] Error 2 H...
So I'm just tinkering around with C and wanted to see if I could assign a binary value to an integer and use the printf() function to output either a signed or unsigned value. But regardless I get the same output, I thought I'd get half the value for printing the signed compared to the unsigned. I'm using Code::blocks and GCC. Does pr...
I knew gcc linker always looking extern function in later obj or lib file. is there a way tell linker looking reference in entire obj file or lib, if linker did not find in later obj. for examole, ld a.obj b.obj c.obj if linker did not find x function in a.obj, it will looking into b.obj or c.obj. if linker did not find xx function ...
I'm using the GCC compiler and C++ and I want to make a timer that triggers an interruption when the countdown is 0. Any Ideas? Thanks in advance. EDIT Thanks to Adam, I know how to do it. Now. What about multiple timers running in parallel? Actually, these timers are for something very basic. In NCURSES, I have a list of things. W...
Not so long ago I've installed Debian and configured it with my friend's help. Yesterday I have downloaded GCC 4.4 and I created a simple program to test it out. This is the code: #include <stdio.h> int main () { int result; printf ("Hello Wor... Linux! This is my %dst program compiled in Debian.\nHow many is 2+2?\n", 1); s...
I'm getting a compiler error on FreeBSD: error: invalid combination of multiple type-specifiers From the C++ Code: typedef unsigned off_t uoff_t; Not sure what the gcc compiler is trying to tell me. ...
I added following at line 42 of proto.h: typedef boost::make_unsigned<off_t>::type uoff_t; And now I get this verbose and confusing warning from gcc complaining about comparing an enum to the same enum type: In file included from proto.cpp:12: /usr/local/include/boost/type_traits/is_unsigned.hpp: In instantiation of 'boost::detail::i...
I'm using C++ under Linux compiling with standard GCC. In my program I want to add a simple clock showing HH:MM:SS. What's the easiest way to do that? ...
I have the following code (I'm sorry for the lengthiness): double primeValue( const func1D &func, const double lowerBound, const double upperBound, const double pole ) { // check bounds if( lowerBound >= upperBound ) throw runtime_error( "lowerBound must be smaller than upperBound!" ...
Hi, I started using eclipse CDT over Linux for some college exercises. I want the build function to compile without linking? Can i have the build to be as simple as: gcc -c -Wall ? Thanks ...
Hi, I am using Intel Core2Duo E4500 processor. It is supposed to have SSE3, SSSE3 facilities. But if I try to use them in programs it shows the following error "SSE3 instruction set not enabled" Any ideas? ...
I occasionally use 64 bit arithmetic in an open source C++ library of mine. I discovered that long long serves my purpose quite nicely. Even some 10 year old solaris box could compile it. And it works without messing around with #defines on Windows too. Now the issue is I get complaints from my users because they compile with GCC -pedan...

If I have a structure such as typedef struct _people { char *name; bool *exists; struct _people **citizens; } PEOPLE; How do I go about allocating memory so that people->citizens[0]->name is accessible? I've tried info->citizens = malloc(sizeof(PEOPLE *)*numbPeople); However when I try to access info->citizens->name I get th...
In gcc 4.5 the stack must be aligned to a 16-byte boundary when calling a function (previous versions only required a 4-byte alignment). 4-byte is reasonable for 32-bit machine. 16-byte is easy to align by just "and 0xfffffff0, %esp". But it might cost much more memory than 4-byte boundary, doesn't it? In short, My question is why gcc ...
