Extract text from GNU Makefiles (GNUMAKEFILE)
To convert GNUMAKEFILE Makefiles to another format, you need GNU Make or other Developer software.
To convert other file formats to the "Build Script" file type, you need software like GNU Make or a similar tool.
A .gnumakefile is a plain text build script used by GNU Make to automate the compilation and generation of executables from software source code. It contains explicit rules, file dependencies, and shell commands required to build a project. Developers typically execute these files via the make command-line utility on Linux and macOS systems. You can read more about the underlying mechanics on Wikipedia.
Users often need to convert or migrate these files when modernizing a software project. A major disadvantage of the .gnumakefile format is its rigid and unforgiving syntax. It strictly demands literal tab characters for indentation; a single space in the wrong place will cause the entire build to fail. Furthermore, it is heavily tied to the GNU ecosystem, making cross-platform builds on Windows difficult without installing emulation layers like Cygwin or MinGW.
When migrating away from legacy build tools, the best conversion targets are modern, cross-platform formats like CMakeLists.txt (for CMake) or build.ninja (for Ninja). If you simply need to review the code outside of an IDE, converting to TXT or MD is recommended to preserve readability.
Converting a .gnumakefile to another build system is notoriously difficult. Standard online converters fail to process it because translating shell commands and conditional macros requires intelligent logic mapping, not just file wrapper changes.
Convert.Guru analyzes your GNUMAKEFILE file, detects the exact format, and lets you read the text inside.
If you want to convert GNUMAKEFILE file to , you can use GNU Make or similar software from the "Automated Software Build Script" category. In the File menu, look for Save As… or Export….
To convert files to GNUMAKEFILE, try GNU Make or another comparable tool in the "Automated Software Build Script" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our GNUMAKEFILE converter.
