## Setting up prerequisites
|
|
|
|
Currently, only Ubuntu 14.04+ is officially supported as primary development environment.
|
|
|
|
There are several dependencies, that should be installed manually. The following list is the absolute minimum for building:
|
|
|
|
- `gcc` or any C99-compliant compiler (native or cross, e.g., arm-none-eabi)
|
|
- `cmake` >= `2.8.12.2`
|
|
|
|
Several scripts and tools help the building and development process, thus it is recommended to have the following installed as well:
|
|
|
|
- `bash` >= `4.3.11`
|
|
- `cppcheck` >= `1.61`
|
|
- `vera++` >= `1.2.1`
|
|
- `python` >= `2.7.6`
|
|
|
|
```bash
|
|
sudo apt-get install gcc gcc-arm-none-eabi cmake cppcheck vera++ python
|
|
```
|
|
|
|
To make our scripts run correctly, several shell utilities should be available on the system:
|
|
|
|
- `awk`
|
|
- `bc`
|
|
- `find`
|
|
- `sed`
|
|
|
|
## Building JerryScript
|
|
|
|
**To build debug version for Linux**
|
|
|
|
```bash
|
|
python tools/build.py --debug
|
|
```
|
|
|
|
**To build debug version for Linux without LTO (Link Time Optimization)**
|
|
|
|
```bash
|
|
python tools/build.py --debug --lto=off
|
|
```
|
|
|
|
**Add custom arguments to CMake**
|
|
|
|
```bash
|
|
python tools/build.py --cmake-param=CMAKE_PARAM
|
|
```
|
|
|
|
**Set a profile mode (ES5.1, subset of ES2015, minimal)**
|
|
|
|
```bash
|
|
python tools/build.py --profile=es5.1|es2015-subset|minimal
|
|
```
|
|
|
|
**Use (jerry, compiler-default, external) libc**
|
|
|
|
The default libc is jerry-libc, but you can use compiler-default libc or an external libc:
|
|
|
|
- compiler-default libc:
|
|
|
|
```bash
|
|
python tools/build.py --jerry-libc=off
|
|
```
|
|
|
|
- external libc:
|
|
|
|
```bash
|
|
python tools/build.py --jerry-libc=off --compile-flag="-nostdlib -I/path/to/ext-libc/include" --link-lib="ext-c"
|
|
```
|
|
|
|
**Add toolchain file**
|
|
|
|
The ```cmake``` dir already contains some usable toolchain files, which you can use in the following format:
|
|
|
|
```bash
|
|
python tools/build.py --toolchain=TOOLCHAIN
|
|
```
|
|
|
|
For example the cross-compile to RaspberryPi 2 is something like this:
|
|
|
|
```bash
|
|
python tools/build.py --toolchain=cmake/toolchain_linux_armv7l.cmake
|
|
```
|
|
|
|
**Use system memory allocator**
|
|
|
|
```bash
|
|
python tools/build.py --system-allocator=on --jerry-libc=off
|
|
```
|
|
|
|
*Note*: System allocator is only supported on 32 bit systems.
|
|
|
|
**Enable 32bit compressed pointers**
|
|
|
|
```bash
|
|
python tools/build.py --cpointer-32bit=on
|
|
```
|
|
|
|
*Note*: There is no compression/decompression on 32 bit systems, if enabled.
|
|
|
|
**Change default heap size (512K)**
|
|
|
|
```bash
|
|
python tools/build.py --mem-heap=256
|
|
```
|
|
|
|
If you would like to use more than 512K, then you must enable the 32 bit compressed pointers.
|
|
|
|
```bash
|
|
python tools/build.py --cpointer-32bit=on --mem-heap=1024
|
|
```
|
|
|
|
*Note*: The heap size will be allocated statically at compile time, when JerryScript memory
|
|
allocator is used.
|
|
|
|
**To get a list of all the available buildoptions for Linux**
|
|
|
|
```bash
|
|
python tools/build.py --help
|
|
```
|
|
|
|
## Checking patch
|
|
|
|
```bash
|
|
python tools/run-tests.py --precommit
|
|
```
|
|
|
|
### Running only one type of test
|
|
|
|
**To run build option tests**
|
|
|
|
```bash
|
|
python tools/run-tests.py --buildoption-test
|
|
```
|
|
|
|
**To run unittests**
|
|
|
|
```bash
|
|
python tools/run-tests.py --unittests
|
|
```
|
|
|
|
**To run jerry-tests**

|
|
|
|
**To run jerry-test-suite**
|
|
|
|
```bash
|
|
python tools/run-tests.py --jerry-test-suite
|
|
```
|
|
|
|
**To run signed-off check**
|
|
|
|
```bash
|
|
python tools/run-tests.py --check-signed-off
|
|
```
|
|
|

```bash
|
|
