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.
|
|
|
|
|
|
|
|
|
|
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.

Please note that when specifying a compilation dir throughout the compilation process (via the <COMPILATION_DIR_PATH> environment variable), DO NOT use relative pathing, or special bash characters such as `~`. Relative pathing / special bash characters will not get parsed correctly!
|
|
|
|
|
|
|
|
|
|
Instead, always use absolute paths.

# 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 experience.
|
|
|
|
|
Thus, I recommended using a custom libiconv and compiling it into gdb.

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:
|
|
|
|
|
1. run `./gitsub.sh pull`
|
|
|
|
|
2. run `./autogen.sh` to create the configure script from configure.sh.
|
|
|
|
|
3. create a build dir (e.g build), and then cd into it.
|
|
|
|
|
4. run `../configure --enable-static`
|
|
|
|
|
5. run `cp -r ./include ./lib/.libs/`
|
|
|
|
|
6. run `mkdir ./lib/.libs/lib/`
|
|
|
|
|
7. run `cp ./lib/.libs/libiconv.a ./lib/.libs/lib/`
|
|
|
|
|
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/`
|
|
|
|
|
VII) run `cp ./lib/.libs/libiconv.a ./lib/.libs/lib/`
|
|
|
|
|
|
|
|
|
|
## 2) Compiling gdb
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
Clone gdb from sourceware - https://sourceware.org/git/binutils-gdb.git.
|
|
|
|
|
I checked out to the 15.2 tag.
|
|
|
|
|
|
|
|
|
|
Work according to the following steps:
|
|
|
|
|
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)`.
|
|
|
|
|
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)`.
|
|
|
|
|
|
|
|
|
|
gdb will sit under gdb/gdb.
|
|
|
|
|
gdbserver will sit under gdbserver/gdbserver.
