| There are configure scripts in this directory to generate the header files |
| used by the jemalloc library. |
| |
| These scripts are named conf_<HOST_TYPE>.sh, where HOST_TYPE is one of |
| aarch64, arm, mips, x86, x86_64. |
| |
| In order to build generate the header files for each supported HOST_TYPE, |
| follow these steps: |
| |
| - source build/envsetup.sh |
| - lunch <TARGET> |
| - mmma -jXX bionic |
| - cd external/jemalloc |
| - autoconf |
| - <Modify the configure script> |
| - android/conf_<HOST_TYPE>.sh |
| |
| Follow these instructions to modify the configure script before running |
| any of the conf_<HOST_TYPE>.sh scripts. |
| |
| In the code that looks similar to this: |
| |
| case "${host}" in |
| *-*-darwin*) |
| |
| Modify it to be: |
| |
| case "${host}" in |
| *android*) |
| CFLAGS="$CFLAGS" |
| CPPFLAGS="$CPPFLAGS -D_GNU_SOURCE" |
| abi="elf" |
| force_tls="0" |
| enable_tls="0" |
