Note the path. We'll assume `/home/user/djgpp`. 827b27ec6Sopenharmony_ci* Add the `bin` folder to your `PATH`. In bash, do `export PATH=/home/user/djgpp/bin:$PATH`. 927b27ec6Sopenharmony_ci* The `Makefile` in `contrib/djgpp/` sets up `CC`, `AR`, `LD` for you. So, `CC=i586-pc-msdosdjgpp-gcc`, `AR=i586-pc-msdosdjgpp-ar`, `LD=i586-pc-msdosdjgpp-gcc`. 1027b27ec6Sopenharmony_ci 1127b27ec6Sopenharmony_ci## Building LZ4 for DOS 1227b27ec6Sopenharmony_ciIn the base dir of lz4 and with `contrib/djgpp/Makefile`, try: 1327b27ec6Sopenharmony_ciTry: 1427b27ec6Sopenharmony_ci* `make -f contrib/djgpp/Makefile` 1527b27ec6Sopenharmony_ci* `make -f contrib/djgpp/Makefile liblz4.a` 1627b27ec6Sopenharmony_ci* `make -f contrib/djgpp/Makefile lz4.exe` 1727b27ec6Sopenharmony_ci* `make -f contrib/djgpp/Makefile DESTDIR=/home/user/dos install`, however it doesn't make much sense on a \*nix. 1827b27ec6Sopenharmony_ci* You can also do `make -f contrib/djgpp/Makefile uninstall` 1927b27ec6Sopenharmony_ci 2027b27ec6Sopenharmony_ci[0]: https://github.com/andrewwutw/build-djgpp 2127b27ec6Sopenharmony_ci[1]: https://github.com/andrewwutw/build-djgpp/releases 22
