- Subject: Problems with recent GDB Cygwin builds
Using recent Cygwin builds, either trunk or 7.3 branch,
I do get problems with iconv DLL.
Typically, all string display fail.
Easiest way to check is
compile new TRUNK gdb
go to build/gdb dir
prompt# ./gdb ./gdb
...
(top-gdb) print version
$1 =
(top-gdb)
while
prompt# ./gdb ./gdb
...
(top-gdb) p version
$1 = "7.2.90.20110414-cvs"
(top-gdb)
Trying to debug this, I clearly see that iconv callsdo fail
iconv is a macro and really calls libiconv which is in cygiconv-2.dll
as $eax=-1 on return.
$ cygcheck.exe -s |grep iconv
980k 2011/01/28 E:\cygwin-1.7\bin\cygiconv-2.dll
libiconv 1.13.1-2 OK
libiconv2 1.13.1-2 OK
The problem seems to be that wchar_iterate returns 2 while
the expected result is 0 or 1.
Mingw32 or mingw64 seem to work just fine.
Does anyone else have the same kind of troubles?
Pierre Muller.
PS: I tried to compile libiconv-1.13.1-2 but it seems to require me to
install
lots of stuff I don't have ...
