On my machine (Windows running cygwin) it compiles correctly. Flex is version 2.5.35 and bison is version 2.3 On linux machine 1 it compiles correctly. Flex is version 2.5.4 and bison is version 1.875c. On linux machine 2 it does not compile correctly. Flex is version 2.5.4 and bison is 2.3. One would expect by looking at the flex/...
According to Apple's gcc 4.2.1 doc: -arch arch Compile for the specified target architecture arch. The allowable values are 'i386', 'x86_64', 'ppc' and 'ppc64'. Multiple options work, and direct the compiler to produce “universal” binaries including object code for each architecture specified with -arch. This option o...
Because I'm a novice to all things C++ and gcc related I need to understand something that's potentially critical. If I use .mm files in a new iphone project whose output is a static lib I get this error: "___gxx_personality_v0", referenced from: If I change the C++ Standard Library type from Dynamic (the default) to static the err...
Purpose I am writing a network program in C (specifically gnu89) and I would like to simplify things by reinterpreting a certain struct X as big array of bytes (a.k.a. char), sending the bytes over the network, and reinterpreting them as struct X on the other side. To this end I have decided to use gcc's __attribute__((__packed__ )). I ...
I've been trying to learn ANTLR and get it working with C output code using this tutorial (also referenced in this question). I successfully got ANTLR to generate the lexer and parser as C source, but I cannot get them to compile using gcc on Mac OS X Snow Leopard (i686-apple-darwin10-gcc-4.2.1). Below is the result when I try to compile...
We are using precompiled headers with GCC for our project and build them like this: gcc $(CFLAGS) precompiledcommonlib.h Now I'm building the project on OSX 10.6 and trying to use the nifty feature of building for all architectures at the same time like this: gcc $(CFLAGS) -c -arch i386 -arch x86_64 commonlib.c However, it seems th...
I have some guys here who have code that needs to be compiled with gcc-3.3. We have a CentOS 5.2. When we compile it with their make files, it fails during the link and they say it is because it won't work with gcc-3.4 which is installed already. Is there something I need to tell them to change to make it go, or is it possible to find...
I'm running gcov/gcc 4.1.2 on RHEL. When I want to specify a directory for the gcov files. Any ideas on how to do this? ...
I've recently upgraded my Ubuntu installation from Jaunty to Karmic. This apparently includes an update of the GNU C compiler, because code that compiled previously no longer does. Running cc 4.4.1 (Ubuntu 4.4.1-4ubuntu8) now produces the following error, on code that worked fine in the cc 4.3.3 (Ubuntu 4.3.3-5ubuntu4): $ make cc -c -M...
After many years of working on a general-purpose C++ library using the Microsoft MSVC compiler in Visual Studio, we are now porting it to Linux/Mac OS X (pray for us). I have become accustomed and quite fond of the simple memory leak detection mechanism in MSVC: #ifdef DEBUG #define _CRTDBG_MAP_ALLOC #define NEW new( _NORMAL_B...
I've got some .so libraries that I'd like to combine into one shared library so that it doesn't depend on the original .so files anymore. The .so files have dependencies to each other. How can I do this? Can I do this? ...
Is there a compiler directive in order to ignore the "initialization from incompatible pointer type" warnings in Hardware_MouseDrivers_GPM_Methods and Hardware_MouseDrivers_DevInput_Methods? Turning off warnings globally is not an option though. #include <stdio.h> /* Mouse driver interface */ typedef struct _Hardware_MouseDriver { ...
Hi I am trying to compile go file using gccgo , i installed on my ubuntu 9.10 machine . when i compiled $gccgo -c hello.go hello.o file is generated , while trying to link and to form an executable $gccgo -o hello hello.o i get the following error /usr/local/lib/gcc/i686-pc-linux-gnu/4.5.0/../../../libgo.so: undefined referen...
Why if I change the size of one of the dimensionality of an array I get a run-time Error: "Segmentation Fault?". Example: #include <stdio.h> #define DIM 8 int main(int argc, char **argv) { int a[3][3][3][3][3][3][3][3][3][3][DIM], b; a[1][1][1][1][1][1][1][1][1][1][1] = 2; b=a[1][1][1][1][1][1][1][1][1][1][1]; p...
Hi, I've got quite a large Xcode project that since an Xcode upgrade is giving me loads of "'weak_import' attribute ignored" warnings, they are coming from WebKit, and a bit of research suggests it's a compiler bug. Is there anyway to suppress them, I'm getting thousands, making the 'real' warnings impossible to find. Cheers MT ...
Usually I work with 3D vectors using following types: typedef vec3_t float[3]; initializing vectors using smth. like: vec3_t x_basis = {1.0, 0.0, 0.0}; vec3_t y_basis = {0.0, 1.0, 0.0}; vec3_t z_basis = {0.0, 0.0, 1.0}; and accessing them using smth. like: x_basis[X] * y_basis[X] + ... Now I need a vector arithmetics using SSE i...
Is it possible to globally disable NUL-terminated strings in GCC? I am using my own string library, and I have absolutely no need for the final NUL characters as it already stores the proper length internally in a struct. However, if I wanted to append 10 strings, this would mean that 10 bytes are unnecessarily allocated on the stack. ...
Hi, I'm running Mac OS X 10.5.8 and want to compile for target CentOS 5.3 with GCC 4.1.2. How could I: Compile GCC 4.1.2 toolchain and related tools? Use that tool to cross compile for target CentOS 5.3? Any help is greatly appreciated! ...
Background: Keil C51 on a PC, currently moving to GCC (CrossPack-AVR) on an iMac. Since I write firmware for micro's I have a lot of 'driver' source files etc. that I need to include with my programs, e.g. a LCD driver, i.e. reusing code. These code snippets (.c and .h files) live sub folders in a /snippets/ folder, i.e. /snippets...
