The Stdio Implementation

I'm guessing that the author of config.guess has never had the need to distinguish between GNU libc and musl, and hasn't written a test for it. I wouldn't worry about it unless it's causing something to break, anyway.

glibc allows the usage of versioned symbols through version tables in gnu-specific elf sections. the musl dynlinker only supports the subset of symbol ...

When building musl, you will also need a C99 compiler with support for gcc-style __asm__ statements and assembly source files, and weak symbol support in the linker. gcc 3.3 or later (with the GNU assembler and linker) and clang 3.2 or later are known to work. Users have also had success building musl with PCC and Firm/cparser.

I'm very late but I noticed one peculiarity of musl libc while trying to find an answer to the same question (in my case, it's that musl doesn't implement pthread_setname_np). It doesn't define __USE_GNU in features.h when _GNU_SOURCE is defined and instead uses _GNU_SOURCE to guard GNU extensions.

On non-GNU (Alpine) it is just "Linux" while on Ubuntu, Debian and OpenSUSE it is "GNU/Linux". You may also have success determining GNU vs.

Jan 20, 2022 · On non-GNU (Alpine) it is just "Linux" while on Ubuntu, Debian and OpenSUSE it is "GNU/Linux". You may also have success determining GNU vs. MUSL by iterating /lib* directories looking for libc variants. This is similar to the approach taken when compiling the JDK, which executes the ldd command and parses libraries from that output.

musl is more lightweight,neat and well-thoughy with considerably less code comes also much more security, which is the main and probably the only (still surely relevant) musl pro; musl vs glibc performance benchs are often contradictory. musl would perform better only on limited specs/embedded.

When building musl, you will also need a C99 compiler with support for gcc-style __asm__ statements and assembly source files, and weak symbol support in the linker. gcc 3.3 or later (with the GNU assembler and linker) and clang 3.2 or later are known to work.

on: How to compile C apps with musl and Clang ... libcs have been to make tradeoffs for use on embedded systems (uClibc) or political/license differences.

Performance just isn't a reason to choose between musl/glibc. The difference isn't big enough to significantly matter (in any benchmarks I've seen to date).

20.01.2022 · Another option for finding GNU distributions is the uname -o command that you can execute with a ProcessBuilder. On non-GNU (Alpine) it is just "Linux" while on Ubuntu, Debian and OpenSUSE it is "GNU/Linux". You may also have success determining GNU vs. MUSL by iterating /lib* directories looking for libc variants.

Jul 25, 2012 · musl is strict about namespaces. As a quick fix, add to your CFLAGS -D_GNU_SOURCE for GNU- and Linux-specific functions like strndup, and add -D_BSD_SOURCE for BSD-specific functions like strlcpy. If you are the maintainer of the package, consider determining the correct namespace and adding it to the relevant .c files.

Understanding why a rust app fails within an alpine container when compiling using target `aarch64-unknown-linux-gnu` and why I cant build using `aarch64-unknown-linux-musl` So I was trying to setup a fork of an open source repo with GitHub Actions and wanted to create a CI/CD pipeline where the compiled binaries and static libraries could be built for x86_64 and aarch64 .

musl is faster, it is rare but you can still get errors on some programs. personally i use musl for servers and glibc for desktop (able to run 32-bit programs, etc) level 2. · 2 yr. ago. AFAIK musl is not faster, just not so resource heavy as glibc. This is why it's recommended for low-end and embedded systems. r/voidlinux.

musl is a C standard library intended for operating systems based on the Linux kernel, released under the MIT License. It was developed by Rich Felker with ...
