[Mingw-msys] Odd compilation problem: output under MSYS's shell, nothing under Windows' shell

["Antonio García" <nyoescape@xxxxxxxxx>]

Hello all,

I'm getting a really weird problem with I/O under MSYS. I've got a C++ program compiled with -mwindows, which among other things, asks for a password.

After much mucking, I got a snippet of code that did what I wanted from the cURL project, but the getch() function doesn't quite work: it just keeps gobbling characters from God knows where, instead of asking me. I thought that it might be the doing of MSYS' shell, so I tried running my program under the ol' MS-DOS shell, but then there's no output at all! I tried fflush()ing stdin and stdout before doing getch, but it doesn't do anything.

What might I be doing wrong? Oh, and by the way, if I use -ggdb when compiling and then try running the program, it barfs on me.

The command I use for linking is:

g++ -o scenario-client src/FileDownloader.o src/client.o src/ConsoleSecretsAgent.o src/SecretsAgent.o lib/getpass.o -lssl -lcrypto -L/mingw/lib -lneon -lssl -lcrypto -lws2_32 -lws2_32 -lz -L/mingw/lib -lxml2 -lz -liconv -lws2_32 -mwindows

For compiling, I use stuff like:

g++ -Wall -I/mingw/include/neon -Isrc -Ilib -ggdb -DNDEBUG -c -o src/SecretsAgent.o src/SecretsAgent.cpp

And then GDB says this:

$ gdb ./scenario-client.exe

(gdb) c:/cygmnt/prj/pkg/src/gdb/mingw32/gdb/dwarf2read.c:985: gdb-internal-error: read_comp_unit_head: dwarf from non elf file

I'm a bit weirded out by all this. Might it be the fault of one of the libraries? I compiled them all myself under mingw, so I don't think it's a problem of binary compatibility.

Thanks,
Antonio
