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.
Many thanks and best regards,
Mario
