Note the path. We'll assume `/home/user/djgpp`. 8*27162e4eSAndroid Build Coastguard Worker* Add the `bin` folder to your `PATH`. In bash, do `export PATH=/home/user/djgpp/bin:$PATH`. 9*27162e4eSAndroid Build Coastguard Worker* 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`. 10*27162e4eSAndroid Build Coastguard Worker 11*27162e4eSAndroid Build Coastguard Worker## Building LZ4 for DOS 12*27162e4eSAndroid Build Coastguard WorkerIn the base dir of lz4 and with `contrib/djgpp/Makefile`, try: 13*27162e4eSAndroid Build Coastguard WorkerTry: 14*27162e4eSAndroid Build Coastguard Worker* `make -f contrib/djgpp/Makefile` 15*27162e4eSAndroid Build Coastguard Worker* `make -f contrib/djgpp/Makefile liblz4.a` 16*27162e4eSAndroid Build Coastguard Worker* `make -f contrib/djgpp/Makefile lz4.exe` 17*27162e4eSAndroid Build Coastguard Worker* `make -f contrib/djgpp/Makefile DESTDIR=/home/user/dos install`, however it doesn't make much sense on a \*nix. 18*27162e4eSAndroid Build Coastguard Worker* You can also do `make -f contrib/djgpp/Makefile uninstall` 19*27162e4eSAndroid Build Coastguard Worker 20*27162e4eSAndroid Build Coastguard Worker[0]: https://github.com/andrewwutw/build-djgpp 21*27162e4eSAndroid Build Coastguard Worker[1]: https://github.com/andrewwutw/build-djgpp/releases 22
