HI, I've built MInGW using the sources GCC version 4.7.1. When using LTO '-flto=N' when N greater 1 - I get the following error: > "make": [C:\Users\niXman\AppData\Local\Temp\ccl7QYlh.ltrans0.ltrans.o] Error 1 (ignored) If I use '-flto' или '-flto=1' then the error is absent. Tell me please, where is this error printed from? Because of what? This error is found also in gcc-4.6.3 and gcc-4.7.0. I'd like to have an working LTO whith more than one thread. Thanks! -- Regards, niXman ___________________________________________________ Dual-target(32 & 64 bit) MinGW compilers for 32 and 64 bit Windows: http://sourceforge.net/projects/mingwbuilds/
