This HOWTO explains how to cross-compile CRIU on x86
|
|
|
|
1. Download the protobuf sources.
|
|
2. Apply the patch http://16918.selcdn.ru/crtools/aarch64/0001-protobuf-added-the-support-for-the-acrchitecture-AAr.patch
|
|
3. Configure protobuf to be compiled for the target architecture:
|
|
|
|
./configure --prefix=$X86_PREFIX --disable-shared --enable-static
|
|
|
|
4. Compile protobuf.
|
|
5. Download protobuf-c sources.
|
|
6. Configure protobuf-c for the architecture x86:
|
|
|
|
export PATH=$PATH:$X86_PREFIX/bin
|
|
export PKG_CONFIG_PATH=$X86_PREFIX/lib/pkgconfig
|
|
CPPFLAGS=`pkg-config --cflags protobuf` LDFLAGS=`pkg-config --libs protobuf` ./configure --prefix=$X86_PREFIX --disable-shared --enable-static
|
|
|
|
7. Compile and install protobuf-c.
|
|
8. Configure protobuf to be compiled for the target architecture:
|
|
|
|
./configure --prefix=$ARCH_PREFIX --disable-shared --enable-static --with-protoc=protoc --host=$TARGET
|
|
|
|
9. Compile and install protobuf.
|
|
10. Let PKG_CONFIG_PATH=$ARCH_PREFIX/lib/pkgconfig.
|
|
11. Configure protobuf-c to be compiled for the target architecture:
|
|
|
|
CPPFLAGS=`pkg-config --cflags protobuf` LDFLAGS=`pkg-config --libs protobuf` ./configure --prefix=$ARCH_PREFIX --disable-shared --enable-static --disable-protoc --host=$TARGET
|
|
|
|
12. Compile and install protobuf-c.
|
|
13. Compile CRIU:
|
|
|
|
ARCH=<target arch> CROSS_COMPILE=$TARGET- CFLAGS=`pkg-config --cflags libprotobuf-c` LDFLAGS="`pkg-config --libs libprotobuf-c`" make
|
|

Special notes for Android NDK cross compile:
|
|
|
|
1, Android NDK doesn't have some headers required by CRIU build, they are <aio.h>, <sys/fanotify.h>
|
|
|
|
2, Android NDK doesn't have some function required by CRIU build, they are aio*, fanotify_init, fanotify_mark, povit_root, index.
|
|
|
|
3, in order to pass build with Android NDK, you implement them yourself, and link them to CRIU.
