[ptxdist] Qt5 and iconv: QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed

[Matthias Klein]

[-- Attachment #1.1: Type: text/plain, Size: 1189 bytes --]

Hello,

every qt5 (console programm) which I compile against qt5 from the latest 
ptxdist version showes the following messages at start: (but then starts 
/ runs)
QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open 
failed
QIconvCodec::convertFromUnicode: using Latin-1 for conversion, 
iconv_open failed
The libc contains the iconv functions:
/opt/OSELAS.Toolchain-2014.12.1/arm-cortexa8-linux-gnueabihf/gcc-4.9.2-glibc-2.20-binutils-2.24-kernel-3.16-sanitized/bin/arm-cortexa8-linux-gnueabihf-nm 
~/bsp/platform-tx53-3.12-rt/root-debug/lib/libc-2.20.so | grep iconv
00016c18 T iconv
00016d54 T iconv_close
00016a90 T iconv_open
There are also modules in the rootfs
ls -l /usr/lib/gconv/
-rwxr-xr-x    1 root     root          5504 Nov  4 12:46 ISO8859-1.so
-rwxr-xr-x    1 root     root          9600 Nov  4 12:46 ISO8859-15.so
-rw-r--r--    1 root     root         56284 Nov  4 12:46 gconv-modules

The same console application did run without these messages when 
building against qt4.
(The qt5 build (and the qt4 build in the past) is without GUI)

Does anyone has a tip whats the reason for these messages?


Best regards,
Matthias

I don't know why this happens in qt5 and not in qt4 but I think enabling
the gconv unicode modules (GLIBC_GCONV_UTF) should help.

Yes, that helps. Thank you very much!
