Re: [Liberty-eiffel] eiffel-iup on Windows

[Germán Arias]

Ok, I solve the problem. This is caused by the way Liberty Eiffel call
gcc. This is something like:

gcc -Xlinker -as-no-nedeed -lother_libs -o some_example.exe example11.o
........

The problem is the linker options passed at the beginning. If I move
these options to the end it works (this is write all the command by
hand, because I don't know how modify compile tool). This is:

gcc -o some_example.exe example11.o ........ -Xlinker -as-no-nedeed 
-lother_libs

Is possible change this with some option to compile tool?

Regards
Germán
