I am having the same problem. I switched to 1.3.8 and now when I compile my in-house code I get the same popup window that David sees referring to /dev/null
I do not use -lpthread but do use -lm on my link line: g++ -g -o dgm.tmp Domain.o Element.o Line.o Quad.o Tri.o Edge.o Basis.o polylib.o Field.o Process.o Mesh.o Slab.o Adv_Diff.o Euler.o Navier_Stok es.o Wave.o Curve.o dgm.o parser.tab.o lex.yy.o -L/home/collis/dist/atlas/ -llapack -lcblas -latlas -lblas -lg2c -lm -L/usr/local/lib -lrfftw -lfftw Similar to David, "cygcheck dgm.exe" was Found: .\dgm.exe .\dgm.exe C:\cygwin\bin\cygwin1.dll C:\WINNT\System32\KERNEL32.dll C:\WINNT\System32\NTDLL.DLL but now gives Found: .\dgm.exe .\dgm.exe C:\cygwin\bin\cygwin1.dll C:\WINNT\System32\KERNEL32.dll C:\WINNT\System32\NTDLL.DLL /dev/null - Cannot open Unfortaunately for me, unlike David, when I used setup.exe to go back to cygwin-1.3.6-6 the problem did NOT go away...?
