Strace shows this in a dialog box when it fails: The procedure entry point uname_x could not be located in the dynamic link library C:\cygwin64\bin\cyggs-9dll.
Version info: $ uname -a CYGWIN_NT-10.0 DESKTOP-OLN71TE 2.11.2(0.329/5/3) 2018-11-08 14:34 x86_64 Cygwin $ /lib/csih/winProductName.exe Microsoft Windows 10 Professional, 64-bit (build 17763) Cygwin 'setup' version is 2.897 64 bit I updated cygwin64 on 8 Jun. Afterward, using 'convert' to create a pdf from a jpg file fails, it worked before. 'convert' appeared not to run when trying convert somefile.jpg somefile.pdf, so I ran strace and here is a part of the output: $ strace /usr/bin/convert.exe --- Process 43956 created --- Process 43956 loaded C:\Windows\System32\ntdll.dll at 00007fff10b60000 --- Process 43956 loaded C:\Windows\System32\kernel32.dll at 00007fff10a70000 --- Process 43956 loaded C:\Windows\System32\KernelBase.dll at 00007fff0da80000 --- Process 43956 thread 64252 created --- Process 43956 thread 64672 created --- Process 43956 thread 57620 created --- Process 43956 loaded C:\cygwin64\bin\cygMagickWand-6.Q16-6.dll at 00000003ef010000 --- Process 43956 loaded C:\cygwin64\bin\cygwin1.dll at 0000000180040000 --- Process 43956 loaded C:\cygwin64\bin\cygMagickCore-6.Q16-6.dll at 00000003ef3a0000 An exception shows in the strace output before convert fails: --- Process 43956 loaded C:\cygwin64\bin\cyggmodule-2.0-0.dll at 0000000000020000 --- Process 43956 unloaded DLL at 0000000000020000 --- Process 43956 loaded C:\cygwin64\bin\cyggraphite2-3.dll at 00000003c0e40000 --- Process 43956 loaded C:\cygwin64\bin\cyguuid-1.dll at 000000037fcc0000 --- Process 43956, exception c0000139 at 00007fff10bfeb78 --- Process 43956 thread 57620 exited with status 0xc0000139 --- Process 43956 thread 64252 exited with status 0xc0000139 --- Process 43956 thread 60540 exited with status 0xc0000139 --- Process 43956 exited with status 0xc0000139 I've removed and reinstalled ImageMagick a few times and that does not fix the problem.
