Questions tagged [gnu-toolchain]

The GNU toolchain is a broad collection of programming tools produced by the GNU Project. These tools form a toolchain (a suite of tools used in a serial manner) used for developing software applications and operating systems. The GNU toolchain plays a vital role in development of Linux, some BSD systems, and software for embedded systems.

Consider adding specific tool tags.

Cross platform portability

  • - general tag for auto-tool suite.
  • - tool for generating a configure script.
  • - makefiles generation tool.
  • - library portability tool.
  • - for use of the output of autoconf; a configure script.
  • - language used by many autotools.
  • - database of install library options.
  • - the gnu building program.

Code generation

  • - the 'C' compiler.
  • - an assembler.
  • - a yacc tool; parser generator.
  • - the gnu scanner; text to tokens.
  • - the gnu C++ compiler.
  • - a collection of support tools for building. Also:
  • - a newer gnu linker

How do I link a library file in GCC that does not start with lib?

When I link a library such as libm in with ld, I need to drop the lib prefix. What if the file does not follow this naming convention? Is there a way to link it other than renaming the file?
