So you want to cross-compile radare to some exotic architecture? Use docker and you'll save some headache:
|
|
|
|
https://github.com/dockcross/dockcross
|
|
|
|
Here's and example on how changes required for i.e ARMv5 (no hard float) borrowed from `mk/armel.mk`:
|
|
|
|
```
|
|
ARCH=arm
|
|
CROSS_ROOT=/usr/bin
|
|
CROSS_TRIPLET=${ARCH}-linux-gnueabi
|
|
|
|
CC=${CROSS_ROOT}/${CROSS_TRIPLET}-gcc
|
|
USERCC=${CROSS_ROOT}/${CROSS_TRIPLET}-gcc
|
|
|
|
RANLIB=${CROSS_TRIPLET}-ranlib
|
|
CC_AR=${CROSS_ROOT}/${CROSS_TRIPLET}-ar -r ${LIBAR}
|
|
(...)
|
|
```
|
|
|
|
After defining your new `mk/arch.mk` file it should be pretty straighforward to install the `dockcross`
|
|
tool from one of its own containers:
|
|
|
|
```
|
|
$ docker run thewtex/cross-compiler-linux-armv5 > ~/bin/dockcross
|
|
$ chmod +x ~/bin/dockcross
|
|
```
|
|
|
|
And then, compile normally from inside the container:
|
|
|
|
```
|
|
$ dockcross --image thewtex/cross-compiler-linux-armv5 ./configure --with-compiler=armel --host=armel
|
|
$ dockcross make
|
|
```
|
|
|
|
