Hi everyone, In the software project I'm working on, we use certain 3rd party libraries which, sadly, produce annoying gcc warnings. We are striving to clean all code of warnings, and want to enable the treat-warnings-as-errors (-Werror) flag in GCC. Is there a way to make these 3rd party generated warnings, which we cannot fix, to disa...

On Linux, is there a way to embed version information into an ELF binary? I would like to embed this info at compile time so it can then be extract it using a script later. A hackish way would be to plant something that can be extracted using the strings command. Is there a more conventional method, similar to how Visual Studio plant ver...
I have an Embedded linux PowerPC project based on a powerpc-e300c3 core for which I have a board support package that included a GCC set up for a --host=i686-pc-linux-gnu and --target=powerpc-e300c3-linux-gnu. This happily creates executables from a host machine for execution on the embedded machine. For development I have the PowerPC's...
When I run the following command from a makefile on 64-bit Red Hat Enterprise Linux 5.0 using GCC 4.2.3: gcc -c -ansi -pedantic -O0 -fPIC -I. -I.. -Iheader_files/include "source_file.c" I get the following error: cc1: error: unrecognized command line option "-lang-c" Superficially, the problem is that "-lang-c" is no longer a valid...
Is there a way to force '-m64' not overriding CXXFLAGS/CFLAGS. I want automatic x64 build environment like in Linux/BSD amd64. Why do I need this? The problem is complexity of the project I need to be buit as x64 on Solaris. It contains several parts and each may use specific C/C++ compiler flags. So, I can't just run: CXXFLAGS=-m64 ...
I am learning inline assembly in C. As far as I can tell, the only difference between __asm { ... }; and __asm__("..."); is that the first uses mov eax, var and the second uses movl %0, %%eax with :"=r" (var) at the end. Also, there are a lot less websites about the first. What other differences are there? ...
I've been attempting for the last week or so to compile any of the GCC 4 series of compilers to run in MinGW 5.1.6 / MSYS 1.0.11 (automated installers both from Sourceforge.org) which ships with GCC version 3.4.5. The end goal is to get GCC 4.5 to install, but I haven't been able to get any of the 4.x.x compilers to build. I've narrowe...
I'm not sure if it's gmake or gcc that I don't understand here. I'm using the -MM and -MD options to generate dependency rules for the Unit Testing framework I'm using.

Hey I have compiled a cross-compiler tool chain with gcc and glibc. But I'm having some problems with the compiler. When I'm trying to compile a simple file it complains about a missing crti.o and crt1.o. These files does exist in ${TOOLCHAINPATH}/lib, but I do not know how to instruct the compiler/linker to look their. So, how can I...

My code receives a time_t from an external source. However, that time_t isn't acutally based on UTC Epoch time, along with it I get a timezone string (eg, EDT, PST, etc), and its based on this offset'ed epoch. I need to convert this to a true UTC Epoch based time_t. Additionally, I need to be able to go in the opposite direction, taking...

I was wondering if it's possible to emulate a big-endian behavior, for testing purpose? via either windows or linux , mingw or gcc. Here's a sample of code which I would like the emulation to return big endian: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <limits.h> #if CHAR_BIT != 8 #error "Unsupported char si...
