How to build GDB on Windows

Question

How does one build GDB (the GNU Debugger) from source on Windows? I need to build it in order to make a build with Python support. I cannot use the one distributed with Cygwin because it has problems interpreting backslashes on Windows. What toolchains do I need for the build -- GnuWin32, MinGW, etc.? Can someone please provide step-by-step instructions on how to do this?

Answer 1

1. install (https://sourceforge.net/downloads/mingw) and configure MinGW with packages g++ gcc libc6-dev libtool pkg-config
2. get gdb sources (I use 7.latest from https://www.gnu.org/software/gdb/) and put it into MinGW/msys/1.0 folder
3. run ./configure in msys shell (MinGW\msys\1.0\msys.bat)
4. run make and fix the following:
5. hypot compile error with help of this '::hypot' has not been declared
6. undefined constants for GetLastError function by adding #include <winerror.h> into \gdb\gdbserver\win32-i386-low.c \gdb\gdbserver\win32-low.c gdb\ser-mingw.c

I have checked build process using 7.11.1 and 7.12.1 sources

7.12.1 x32 is broken under windows https://github.com/Alexpux/MINGW-packages/issues/1909 https://sourceforge.net/p/mingw-w64/bugs/576/
