- Authentication-results: sourceware.org; auth=none
Hello. I'm trying to validate a gcc patchset that affects msabi
functions, so I need good test results on Cygwin, but my unpatched tests
are getting hundreds of failures for which I cannot determine the cause.
I'm running Cygwin 64 bit on Windows 7 in a qemu vm (with kvm). My
sources are on a C: drive (gcc's HEAD a from a few days ago), but I
didn't make that device large enough, so I had to add a second device on
D for the builds. I have cygdrive set to / (in /etc/fstab, I have
"none / cygdrive binary,posix=0,user 0 0"), but the
file names it's printing is using the D: format instead of /d. Example:
FAIL: gfortran.dg/coarray/sync_3.f90 -fcoarray=single -O2 output
pattern test, is
D:/builds/head-test-unpatched-x86_64-pc-cygwin/gcc/testsuite/gfortran2/sync_3.exe:
error while loading shared libraries: cyggfortran-4.dll: cannot open
shared object file: No such file or directory
That might not actually be the problem. I do NOT have fortran
installed. I have run a successful "make bootstrap" so the build tree
should have the correct Fortran libs. The file "cyggfortran-4.dll" does
exist at the location
/d/builds/head-test-unpatched-x86_64-pc-cygwin/x86_64-pc-cygwin/libgfortran/.libs/cyggfortran-4.dll.
The even stranger part is that these errors aren't in the build from my
patched sources. Maybe something changed in my environment? I ran my
patched tests firsts, which resulted in much fewer failures and I
haven't re-run them yet to see if it's failing now or not. Any ideas?
This is the snippet from the log for the above failure:

Also, this is how I have configured gcc:
/c/Users/daniel/proj/sys/gcc/work0/configure --host=x86_64-pc-cygwin
--build=x86_64-pc-cygwin --target=x86_64-pc-cygwin
--prefix=/home/daniel/local/gcc-head-test-unpatched-x86_64-pc-cygwin
--enable-stage1-checking=yes,rtl --enable-lto --enable-gold=yes
--enable-bootstrap --with-system-zlib
Thanks,
Daniel
