CYGWIN build issue (std::wstring)

[jkeogh1413]

Searching has failed me. Perhaps this is an isolated error.

CYGWIN version: 1.7.16
Downloaded Basic Edition for Linux/OSX/etc...

./configure
Configured for CYGWIN

$ make

It seems that in this one case std::wstring is still an issue, even with the -DPOCO_NO_WSTRING option.


Any suggestions?

Thanks.

Any suggestions?

Make sure POCO_WIN32_UTF8 is not defined (look in Config.h).

[jkeogh1413]

A+

Is this a typical step when installing on CYGWIN, or was configure supposed to handle it?

Fix:
Navigate to /poco-1.4.4/Foundation/include/Poco
Open 'Config.h'
Comment out the following line:
//#define POCO_WIN32_UTF8
make
make install

Build was smooth.

Thank you.

You have actually discovered a build system inconsistency. Poco comes with POCO_WIN32_UTF8 enabled by default because that's what most windows users need but it should not leak into non-windows build environments or be defined alongside with POCO_NO_WSTRING. It will be fixed in 1.4.4p1 and 1.5.0
