 ## 1) Compiling iconv
 
 While compiling iconv is not a must, the libc-provided iconv (a utility to convert between encodings) may fail on different architectures,
-at least in my experiance. Thus, I recommended using a custom libiconv and compiling it into gdb.

 Make sure to check out to a stable tag (in my case - v1.17).
 
 Work according to the following steps:
-I) run `./gitsub.sh pull`
-II) run `./autogen.sh` to create the configure script from configure.sh.

-I checked out to the 15.2 tag.
+Clone gdb from from my forked respository - https://github.com/guyush1/binutils-gdb/tree/gdb-static.
+
+Make sure to check out to the **gdb-static** branch - this branch contains all of the changes i had to do to the build system in order for it to compile gdb statically.
 
 Work according to the following steps:
-I) Apply my patches (gdb_static.patch). If you are not on the exact tag i used (15.2) - you might need to apply them manually, and change some stuff.
-II) create a build dir.
-III) run `../configure --enable-static --with-static-standard-libraries --disable-tui --disable-inprocess-agent --with-libiconv-prefix=<COMPILATION_DIR_PATH>/lib/.libs/ --with-libiconv-type=static`
-IV) run `make all-gdb -j$(nproc)` - for gdbserver, run `make all-gdbserver -j$(nproc)`.
+1. create a build dir.
+2. run `../configure --enable-static --with-static-standard-libraries --disable-tui --disable-inprocess-agent --with-libiconv-prefix=<COMPILATION_DIR_PATH>/lib/.libs/ --with-libiconv-type=static`
+3. run `make all-gdb -j$(nproc)` - for gdbserver, run `make all-gdbserver -j$(nproc)`.
 
 gdb will sit under gdb/gdb.
