 # Notes about this file - read before proceeding!
 
-While i have already provided the gdb/gdbserver-15 statically compiled binaries for you, some people might want to compile it to a different architecture (without our build scripts), or compile a newer version of gdb in the future :). The rest of the file contains a documentation of the compilation process, in order to help you out.

-## <VARAIBLES> in the script
+NOTE: The compilation guide describes the compilation process in order to create a minimal-working version of gdb. Our build-scripts also provides further capabilites to gdb, such as python and xml support, which are not documented in this file. 
 
-When specifying the compilation dir throughout the compilation process (specified as <COMPILATION_DIR_PATH> in this file), DO NOT use relative pathing, or bash characters such as `~`. They will not get parsed correctly! Instead, use absolute paths only.

 # Compiling gdb statically to the host platform
 
 ## 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.

 Download the source from https://github.com/roboticslibrary/libiconv.git
+
 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.
-III) create a build dir (e.g build), and then cd into it.
-IV) run `../configure --enable-static`
-V) run `cp -r ./include ./lib/.libs/`
-VI) run `mkdir ./lib/.libs/lib/`

+6. run `mkdir ./lib/.libs/lib/`
+7. run `cp ./lib/.libs/libiconv.a ./lib/.libs/lib/`
 
 ## 2) Compiling gdb
 
-Clone gdb from sourceware - https://sourceware.org/git/binutils-gdb.git.
-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.
 gdbserver will sit under gdbserver/gdbserver.
