Hello,Since cygwin1.dll version 3.1.5, I observed the following behavior: If a symbolic link is existing in the PATH environment, programs (external from Cygwin's system directory) using cygwin1.dll cannot be executed anymore. Possibly, because the Cygwin-DLL isn't found anymore. Steps to reproduce: cd / mkdir link_test cp /usr/bin/sed.exe link_test ln -s link_test test export PATH=/test:/link_test:/usr/bin:/bin /link_test/sed cannot be executed $ ldd /link_test/sed ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffffd960000) KERNEL32.DLL => /cygdrive/c/WINDOWS/System32/KERNEL32.DLL (0x7ffffd140000) KERNELBASE.dll => /cygdrive/c/WINDOWS/System32/KERNELBASE.dll (0x7ffffa8e0000) SYSFER.DLL => /cygdrive/c/WINDOWS/System32/SYSFER.DLL (0x550c0000) -> no cygwin- DLLs found If I delete the symbolic link $ ll test lrwxrwxrwx 1 mmattl Users 9 Dec 1 10:14 test -> link_test/ simply with rm test everything is working fine; sed can be executed $ /link_test/sed Usage: /link_test/sed [OPTION]... {script-only-if-no-other-script} [input-file]... [...] And $ ldd /link_test/sed ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffffd960000) KERNEL32.DLL => /cygdrive/c/WINDOWS/System32/KERNEL32.DLL (0x7ffffd140000) KERNELBASE.dll => /cygdrive/c/WINDOWS/System32/KERNELBASE.dll (0x7ffffa8e0000) SYSFER.DLL => /cygdrive/c/WINDOWS/System32/SYSFER.DLL (0x550c0000) cygwin1.dll => /usr/bin/cygwin1.dll (0x180040000) cygintl-8.dll => /usr/bin/cygintl-8.dll (0x3f7110000) cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x3f7160000) It would be great if you could give some advice to this issue.
I think this was fixed by commit 4b4fffe0f2390be6a5be27b6a3ceaa212a3724b2, but I don't have time to check carefully, and I'm going to be AFK for a few days starting tomorrow.
Corinna, could you build a snapshot for Mario to test? If it's not fixed, I'll be able to look it within a week or so.
