Compilation error with GCC [message #46305]

Hi all,

There is a long time I did not come on the forum. I still explore U++ high level capacity for rapid development.
I was interested to test the GCC compiler and I downloaded the upp archive 9687 embedding the Ming compiler. The installation worked perfectly (as usual with U++ Smile

) but I got the following fatal error when compiling the Control4U_Demo project in Bazaar package Confused

D:\Installations\Compilateurs\upp\bazaar\Functions4U\LocalPr ocess2.cpp (151): error: invalid initialization of non-const reference of type 'Upp::WString&' from an rvalue of type 'Upp::Wstring'

Any idea ? or MSC15 is still the preferable alternative ? Rolling Eyes

Thanks in advance for advice

Regards
Biobytes

Thank you BioBytes. Bug is now fixed and Control4U_Demo compiles perfectly with MinGW too.

Best regards

Hello Koldo,

Thank you very much for your reply. I just installed Upp-9694-MingW but still have a compiling error with MingW. My sytem is Win XP with SP3 installed.

The problem is in Function4U package

LocalProcess2.cpp at line 151 "WStringBuffer wscmd(ToSystemCharsetW(command));"

The message error is "D:\Logiciels\Dvt\upp\bazaar\Functions4U\LocalProcess2.cpp (151): error: invalid initialization of non-const reference of type 'Upp::WString&' from an rvalue of type 'Upp::WString'"

Maybe an issue with the conversion of command to WString Confused

Looking forward to hearing from you Razz
