I have removed whole cygwin and reinstalled everything, now ecl is not failing. However sage is still not building. Building log ends with following text (can't upload logs as attachment, don't know why) [sagelib-9.1.beta9] collect2: error: ld returned 1 exit status [sagelib-9.1.beta9] error: command 'g++' failed with exit status 1 [sagelib-9.1.beta9] make[4]: *** [Makefile:33: sage] Error 1 [sagelib-9.1.beta9] make[4]: Leaving directory '/home/Kuba/sage/src' [sagelib-9.1.beta9] [sagelib-9.1.beta9] real 7m43.455s [sagelib-9.1.beta9] user 17m51.494s [sagelib-9.1.beta9] sys 0m56.723s make[3]: *** [Makefile:1942: sagelib] Error 2 make[3]: Leaving directory '/home/Kuba/sage/build/make' make[2]: *** [Makefile:1801: all-start] Error 2 make[2]: Leaving directory '/home/Kuba/sage/build/make'
