             Bug #: 13510
           Summary: Cross compile of gdbserver for w32 fails
           Product: gdb
           Version: 7.3
            Status: NEW
          Severity: normal
          Priority: P2
         Component: remote
        AssignedTo: unassigned@sourceware.org
        ReportedBy: nisse@lysator.liu.se
    Classification: Unclassified


I downloaded gdb-7.3, and I tried to build gdbserver för w32 using

./configure --target=i586-pc-mingw32msvc --host=i586-pc-mingw32msvc
--prefix=/usr/local/w32 CC=i586-mingw32msvc-gcc

make

This failed with errors complaining on uintptr_t not defined:

After adding a #include <stdint.h> to win32-low.c, it compiles all right. Not
sure if this is the right solution, though.

Maybe I should say something on the big picture:

I want to debug one of gmp's testcases, which fails when cross compiled for
w32, and run under wine. The plan is to build a cross gdb,
--host=x86_64-unknown-linux-gnu --target=i586-pc-mingw32msvc, and use this to
attach to a process run as

wine gdbserver.exe ... test-program.exe

I don't yet know if this will work out. Another alternative would be to cross
compile gdb itself (--target=i586-mingw32msvc --host=i586-mingw32msvc), I'm not
sure if that would be better.

I'm doing all this on a x86_64 machine with debian gnu/linux and the mingw32
packages. The i586-mingw32msvc-gcc cross compiler is version 4.4.4.

Can you try the 7.4 prerelease that went out the other day?
According to the log, an include of <stdint.h> was added to
this file between 7.3 and now.

I couldn't find any prerelease tarball (tried google and alpha.gnu.org). So I
checked out the source code using

cvs -d :pserver:anoncvs@sourceware.org:/cvs/src co -r gdb_7_4-branch gdb

And now

./configure --target=i586-mingw32msvc --host=i586-mingw32msvc
make 

works without error.
