-We will now install a libc implementation that works on the CG50. For that we will use [OpenLibm](https://git.planet-casio.com/Lephenixnoir/OpenLibm) and [fxlibc](https://git.planet-casio.com/Vhex-Kernel-Core/fxlibc/)
+We now have successfully corss compiled gcc. However we still need to add a libc and compile gnat. 
+For that we will have to install the required headers into the correct coresponding direcotry
 
 ```bash
-COMPILER_DIR="$(sh-elf-gcc --print-file-name=.)" #TODO: maybe more elegant way to search for path?
-LIBDIR="$COMPILER_DIR"

+
+The `PREFIX` directory is where gcc is going to look for all the system headers. 
+
+### Adding libc
+
+We will now install a libc implementation that works on the CG50. For that we will use [OpenLibm](https://git.planet-casio.com/Lephenixnoir/OpenLibm) and [libfxcg](https://github.com/Jonimoose/libfxcg.git)
+
+```bash
+git clone https://github.com/Jonimoose/libfxcg.git
+cd libfxcg/libc
+```
+replace all the `sh3eb-` with `sh-elf` 
+```bash
+make
+cp the lib files to gcc dir
 ```
 
 Now we install the actual libc 
 
 ```bash
-git clone https://git.planet-casio.com/Vhex-Kernel-Core/fxlibc.git
-cd fxlibc
-cmake -B build-gint -DFXLIBC_TARGET=gint -DCMAKE_TOOLCHAIN_FILE=cmake/toolchain-sh.cmake -DCMAKE_INSTALL_PREFIX="$SYSROOT" #instead of Sysroot use lib/gcc/15.2.0
