CuraEngine Build Error 1

[dalkurac 0]

After finally getting MinGW to work, I now face this build error. Could someone help me with this?

 

g++ -c -Wall -Wextra -Wold-style-cast -Woverloaded-virtual -std=c++11 -DVERSION=

"DEV" -isystem libs -O3 -fomit-frame-pointer -march=pentium4 -flto src/bridge.

cpp -o build/bridge.o

In file included from c:mingwlibgccmingw324.8.1includec++cmath:44:0,

from src/utils/intpoint.h:16,

from src/sliceDataStorage.h:5,

from src/bridge.h:5,

from src/bridge.cpp:2:

c:mingwincludemath.h: In function 'float hypotf(float, float)':

c:mingwincludemath.h:635:30: error: '_hypot' was not declared in this scope

{ return (float)(_hypot (x, y)); }

^

make: *** [build/bridge.o] Error 1

 

Does it have something to do with the include files MinGW is using?

I'm facing same problem too. :(

It seems to be the problem of mingw.

Here is the solution from github but I can't understand how to do that.

Thank you! After getting rid of the -O3 option, it builds without any errors! You must remove the -O3 option located in the CFLAGS tag in the Makefile. I think it's under the Profile if statement.
