Need to have a fully working gcc toolchain for SH3/SH4 architecture.
|
||||
|
||||
Compilation is done by using the adhoc Makefile :
|
||||
`make -f Makefile.prizm` in the main directory
|
||||
Compilation is done for all targets with a single:
|
||||
|
||||
It should produce the library libczlib.a
|
||||
```bash
|
||||
% fxsdk build-fx install
|
||||
```
|
||||
|
||||
The following steps are not automatically done, so please proceed with the following manipulations :
|
||||
* copy the library `libczlib.a` into your SH3/SH4 compiler lib folder
|
||||
* copy `zlib.h` and `zconf.h` files contained in the include folder into the include folder of the SH3/SH4 compiler
|
||||
You can also use the `giteapc install Slyvtt/cZlib1_2_5` command to get an automatic install.
|
||||
|
||||
You can also use the `gitea install Slyvtt/cZlib1_2_5` command to get an automatic install
|
||||
## Using in a program
|
||||
|
||||
when you compile a program for use with Zlib, do not forget to add a `-lczlib` option in your compilator command line.
|
||||
With CMake:
|
||||
|
||||
and then a `#include <zlib.h>` in your C/C++ sources
|
||||
```cmake
|
||||
find_package(czlib 1.2.5 REQUIRED)
|
||||
target_link_libraries(<TARGET> PRIVATE czlib::czlib)
|
||||
```
|
||||
|
||||
With make, link with `-lczlib`.
|
||||
|
||||
In the C/C++ source, `#include <zlib.h>`.
