I have the same issue with cygstart in cygutils 1.4.16-3. "cygstart .; echo $?" says 0. This issue only happens in 64bit cygwin and cygstart in 32bit cygwin works. To look into this problem, I tried to build cygutils from source, however, it fails in the link stage of getclip with the error: /usr/lib/gcc/x86_64-pc-cygwin/10/../../../../x86_64-pc-cygwin/bin/ld: src/clip/getclip.o: in function `getclip': /usr/src/debug/cygutils-1.4.16-3/src/clip/getclip.c:431: undefined reference to `__imp_RtlUnicodeToUTF8N' It seems that -lntdll flag is required to build it. Doesn't this error happen in your environment? So I modified Makefile.am to: src_clip_getclip_LDADD = -lpopt -lntdll src_clip_putclip_LDADD = -lpopt -lntdll and tried to build again and succeeded. The cygstart built locally works fine. So I tried to debug cygstart using gdb and it says: Thread 1 received signal SIGILL, Illegal instruction. The disassembling result at $rip is: => 0x0000000100401c15 <+389>: vmovdqa 0x18c3(%rip),%xmm0 # 0x1004034e0 This is a AVX instruction. My CPU is Core i7-870, which does not support AVX. Then I ran cygstart in another machine whose CPU is Core i7-4790 and it works without the issue. Conclusion: cygstart in cygutils 1.4.16-3 is compiled with AVX extentions, therefore it can not run in old machine. -- Takashi Yano <takashi.y...@nifty.ne.jp> -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
