| 2 | ## General problems |
| 3 |
|
| 4 | 1. `Makefile.am:8: error: 'pkgconfig_DATA' is used but 'pkgconfigdir' is undefined` => please install pkgconfig. |

|
| 6 | ## Windows |
| 7 |
|
| 8 | Cross-compiling Windows binaries is supported: |
| 9 |
|
| 10 | ```console |
| 11 | # For x86_64 (64bit) |
| 12 | $ ./configure CC=x86_64-w64-mingw32-gcc --host x86_64-w64-mingw32 --enable-static-exe |
| 13 | $ make |
| 14 |
|
| 15 | # For i686 (32bit) |
| 16 | $ ./configure CC=i866-w64-mingw32-gcc --host i686-w64-mingw32 --enable-static-exe |
| 17 | $ make |
| 18 | ``` |
| 19 |
|
| 20 | Static builds are recommended to avoid the pthread dynamic linking issue. If a dynamic library is desired, consider defining `BZIP3_DLL_EXPORT` or `BZIP3_DLL_IMPORT`. |
| 21 |
|
| 22 | ## M1 MacOS |
| 23 |
|
| 24 | Make sure that you run `./configure` with `--disable-arch-native`. |
| 25 |
|
| 26 | ## Emscripten |
| 27 |
|
| 28 | Assuming that asm.js code is desired: |
| 29 |
|
| 30 | ``` |
| 31 | emconfigure ./configure --without-pthread --host none-none-none CC=emcc "CFLAGS=-O2 -DBZIP3_VISIBLE=\"__attribute__((used))\"" |
| 32 | make src/bzip3-libbz3.o |
| 33 | emcc -O2 src/bzip3-libbz3.o -o libbz3.js -sWASM=0 --memory-init-file 0 -sFILESYSTEM=0 -sALLOW_MEMORY_GROWTH -s 'EXPORTED_RUNTIME_METHODS=["UTF8ToString"]' |
| 34 | ``` |
| 35 |
|
| 36 | asm.js code size: 118KB (v1.1.7), 34K gzipped. |
| 37 | wasm+js stub code size: 76KB (v1.1.7), 26K gzipped. |
