Recommended compiler and linker flags for GCC – …

developers.redhat.com21/03/2018 · This table does not list flags for managing an executable stack or the .bss section, under the assumption that these historic features have been phased out by now. Documentation for compiler flags is available in the GCC manual.Those flags (which start with -Wl) are passed to the linker and are described in the documentation for ld.. For some flags, additional explanations are in order:

doc.ubuntu-fr.orgIl suffit d’installer le paquet gcc. À noter que lorsque l’on installe le paquet virtuel build-essential, il est fait appel à GCC pour la partie compilation.Mais cela ajoute d’autres utilitaires comme Make qui sont généralement nécessaires à toute compilation plus poussée que le simple bout de code. Il est donc conseillé d’installer directement build-essential.

Library path in gcc – Tran Sang Dev Blog

transang.meThere are two steps to build a program with gcc: compilation and linking.. gcc is mostly responsible for the compilation, while when linking, it uses a linker program (e.g., ld) with some additional flags.. In compilation, gcc only requires header files ( .h files) to ensure that external function calls have correct parameters matched with the definition.

Build path — reproducible-builds.org

reproducible-builds.orgSome tools have flags (like gzip’s -n) that prevent them from writing the path in their output. Proposing patches to add a similar feature in other tools might be sufficiently easy. In most cases however, post-processing is required to either remove the build path or to normalize it to a predefined value. For the specific case of debug symbols, there is currently no good post-processing tool …

Three GCC Flags for Analyzing Memory Usage – …

Perhaps this isn’t too out of the ordinary considering that two of the three …
